Defining Patient Satisfaction after Reverse Total Shoulder Arthroplasty: A Systematic Review.

BACKGROUND: The prevalence of reverse total shoulder arthroplasty (rTSA) has grown rapidly. As indications for the procedure expand, the proportion of patients who have satisfactory outcomes after rTSA has not been well defined. This systematic literature review explores overall patient satisfaction after rTSA and defines patient satisfaction based on indication for surgery. METHODS: A literature search was performed for studies describing patient satisfaction after rTSA in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Papers were included if they investigated patient satisfaction after rTSA at a minimum of 2-year follow-up. Data were collected on patient demographics, including age, gender, and body mass index (BMI). Follow-up duration, indication for surgery, and patient reported outcome measures (PROMs) relating to patient satisfaction were also recorded. RESULTS: There were a total of 5234 patients and 5288 shoulders from the 45 included studies. The overall study population was 61.2% female and the average age was 71.1 years (range 23-99). Satisfaction results were recorded at final follow-up, with average follow-up of 49.1 months (range 24-228). Overall patient satisfaction ranged from 77.7 to 87.8%, depending on patient satisfaction PROMs. When stratified by diagnosis, patients with a diagnosis of glenohumeral osteoarthritis (GHOA) rated better satisfaction on all metrics when compared to patients with a diagnosis of cuff tear arthropathy (CTA) or massive rotator cuff tear (MRCT). CONCLUSION: This systematic review demonstrated that patients who undergo rTSA for either GHOA, CTA, or MRCT are generally satisfied with their procedure, with the rate of satisfaction highest in GHOA. Focusing on patient satisfaction may provide the best overall assessment of health care quality in a very understandable and tangible form. Overall satisfaction rate is valuable information for patient education and can be utilized as part of effective surgical counseling.

Same-Day Discharge vs. Inpatient Total Shoulder Arthroplasty: An Age Stratified Comparison of Postoperative Outcomes and Hospital Charges.

BACKGROUND: As the number of total shoulder arthroplasty (TSA) procedures increases, there is a growing interest in improving patient outcomes, limiting costs, and optimizing efficiency. One approach has been to transition these surgeries to an outpatient setting. Therefore, the purpose of this study was to conduct an age-stratified analysis comparing the 90-day postoperative outcomes of primary TSA in the same-day discharge (SDD) and inpatient (IP) settings with a specific focus on the super-elderly. METHODS: This retrospective study included all patients who underwent primary anatomic or reverse TSA between January 2018 and December 2021 in ambulatory and inpatient settings. The outcome measures included LOS, complications, hospital charges, ED utilization, readmissions, and reoperations within 90-days following TSA. Patients with LOS ≤8 hours were considered as SDD, and those with LOS >8 hours were considered as IP. P <0.05 was considered statistically significant. RESULTS: There were 121 and 174 procedures performed in SDD and IP settings, respectively. There were no differences in comorbidity indices between the SDD and IP groups (ASA score P=0.12, ECI P=0.067). The SDD cohort was younger than the IP group (SDD 67.0 years vs. 73.0 IP years, P<0.001), and the SDD group higher rate of intraoperative tranexamic acid use (P=0.015) and lower estimated blood loss (P=0.009). There were no differences in 90-day overall minor (P=0.20) and major complications (P=1.00), ED utilization (P=0.63), readmission (P=0.25) or reoperation (P =0.51) between the SDD and IP groups. When stratified by age, there were no differences in overall major (P=0.80) and minor (P=0.36) complications among the groups. However, the LOS was directly correlated with increasing age (LOS=8.4 hours in ≥65 to < 75-year cohort vs. LOS=25.9 hours in ≥80-year cohort; P<0.001). There were no differences in hospital charges between SDD and IP primary TSA in all 3 age groups (P=0.82). CONCLUSION: SDD TSA has a shorter LOS without increasing postoperative major and minor complications, ED encounters, readmissions, or reoperations. Older age was not associated with an increase in the complication profile or hospital charges even in the SDD setting, although it was associated with increased LOS in the IP group. These results suggest that TSA can be safely performed expeditiously in an outpatient setting. LEVEL OF EVIDENCE: Level III; Retrospective Comparative Study.

Effects of Opioid-Limiting Legislation in the State of Ohio on Opioid Prescriptions After Shoulder Arthroscopy.

Background: Recent studies have shown that legislation regulating opioid prescriptions in the United States has been successful in reducing the morphine milligram equivalent (MME) prescribed after certain orthopaedic procedures. Purpose: To (1) determine the effect of Ohio's legislation limiting opioid prescriptions after shoulder arthroscopy and (2) identify risk factors associated with prolonged opioid use and increased postoperative opioid dosing. Study Design: Cohort study; Level of evidence, 3. Methods: We reviewed the data of patients who underwent shoulder arthroscopy between January 1, 2016, and March 31, 2020. Patients were classified according to the date of legislation passage (August 31, 2017) as before legislation (PRE) or on/after legislation (POST). Patients were also classified based on the number of opioid prescriptions filled within 30 days of surgery as opioid-tolerant (at least 1 prescription) or opioid-naïve (zero prescriptions). We recorded patient characteristics, medical comorbidities, and surgical details, as well as the number of opioid prescriptions, MME per prescription from 30 days preoperatively to 90 days postoperatively, and the number of gamma-aminobutyric acid (GABA) analogues and benzodiazepine prescriptions from 30 days preoperatively to the date of surgery. Differences between cohorts were compared with the Fisher exact test and Wilcoxon test. A covariate-adjusted regression analysis was used to evaluate risk factors associated with increased postoperative opioid dosing. Results: Overall, 279 patients (n = 97 PRE; n = 182 POST; n = 42 opioid-tolerant; n = 237 opioid-naïve) were included in the final analysis. There was a significant reduction in the cumulative MME prescribed in the immediate (0-7 days) postoperative period (PRE, 450 MME vs POST, 315 MME), the first 30 postoperative days (PRE, 590 MME vs POST, 375 MME), and the first 90 postoperative days (PRE, 600 MME vs POST, 420 MME) (P < .001 for all). The opioid-tolerant cohort had higher MME at every time point in the postoperative period (P < .001). Consumption of preoperative opioid (ß = 1682.5; P < .001), benzodiazepine (ß = 468.09; P < .001), and GABA analogue (ß = 251.37; P = .04) was associated with an increase in the cumulative MME prescribed. Conclusion: Opioid prescription-limiting legislation in Ohio significantly reduced the cumulative MME prescribed in the first 30 days postoperatively for both opioid-naïve and opioid-tolerant patients after shoulder arthroscopy. Consumption of opioids, benzodiazepines, and GABA analogues preoperatively was associated with increased postoperative opioid dosage.

Patient Preferences and Perceptions of Provider Diversity in Orthopaedic Surgery.

BACKGROUND: Orthopaedic surgery in the U.S. historically has been among the least demographically diverse specialties in medicine. Currently, limited data exist on how patients perceive diversity within the field and what patients look for when choosing an orthopaedic surgeon. The purpose of this study was to identify specific patient preferences for surgeon demographics and understand patient perceptions of racial and gender diversity in orthopaedic surgery. METHODS: Nonconsecutive patients from orthopaedic clinics affiliated with a U.S. academic health system voluntarily completed a 39-item questionnaire that surveyed basic demographic information, perception of diversity, racial and gender preferences during surgeon selection, and perception of health-care inequalities. Bivariate analyses were used to test the association between patient-surgeon demographic variables and ratings of diversity. Multiple regression models were used to identify independent predictors of overall perceived diversity ratings. RESULTS: A total of 349 patients (80.6% White, 17.9% Black, and 1.5% other) were analyzed. Black patients were more likely to experience difficulty relating to their surgeon than White patients (11.48% versus 2.29%; odds ratio [OR], 5.62; 95% confidence interval [CI], 1.55 to 21.1; p = 0.004). Moreover, Black patients were more likely to perceive racial bias from their surgeon than White patients (5.17% versus 0.37%; OR, 14.44; 95% CI, 1.14 to 766.29; p = 0.02). While the level of racial diversity perceived by White patients (2.57 of 10) was significantly higher than that perceived by Black patients (2.10 of 10) (p = 0.001), the absolute difference between these 2 figures was small, suggesting that both groups perceived racial diversity in orthopaedics to be low. White and Black patients differed in their importance ranking of a surgeon's race (p < 0.0001): Black patients ranked a surgeon's race with higher importance (mean, 3.49 of 10) when selecting a surgeon compared with White patients (1.45 of 10). Both male and female patients gave relatively low importance rankings for a surgeon's gender (mean, 1.58 of 10 and 2.15 of 10, respectively, p = 0.02). CONCLUSIONS: Patients in this study did not perceive orthopaedic surgery as a diverse field (overall diversity rating, <3 of 10). There were significant racial and gender differences in patients' preferences for specific physician characteristics when choosing an orthopaedic surgeon, which may help explain some instances of perceived racial bias and difficulty relating to their orthopaedic surgeon.

Increase in Deltoid Compartment Pressures Immediately After Arthroscopic Rotator Cuff Repair Does Not Significantly Affect Postoperative Opioid Consumption.

Purpose: To investigate the association between changes in individual (anterior, lateral, and posterior) and overall deltoid compartment pressures and postoperative opioid consumption up to 14 days after primary double-row arthroscopic rotator cuff repair (ARCR). Methods: In 113 consecutive patients undergoing primary double-row ARCR, anterior, lateral, and posterior deltoid compartment pressures were measured prior to incision and immediately after closure with a manometer. Postoperatively, all patients were provided with an identical rehabilitation protocol, quantity and dose of opioid tablets, and pain journal in which to record daily opioid consumption and visual analog scale pain scores for 14 days after surgery. The pain journals were collected at the first postoperative visit, and opioid consumption was calculated based on morphine equivalents. Statistical analysis was performed to determine the association between deltoid compartment pressures and opioid consumption postoperatively. Results: Sixty-nine percent of patients who met the inclusion criteria (74 of 107) returned the pain journals. The mean age at the time of surgery was 57.4 ± 8.8 years (range, 30-75 years), with female patients being significantly older (P = .03). The mean length of surgery was 71.7 ± 16.3 minutes. No significant association between increase in individual (anterior, lateral, or posterior) or mean overall compartment pressures and morphine equivalents of opioid consumption was appreciated on any postoperative day. Conclusions: No significant correlation between increase in individual or overall deltoid compartment pressures after ARCR and postoperative opioid consumption in the immediate postoperative period was found in this study. Level of Evidence: Level II, prospective cohort study.

Trends in Orthopedic Device Innovation: An Analysis of 510(k) Clearances and Premarket Approvals From 2000 to 2019.

The objective of this study was to characterize recent trends in orthopedic device development across different subspecialty areas. Orthopedic 510(k) clearances, premarket approvals (PMAs; together, "authorizations"), and new market entrants from 2000 to 2019 were analyzed as markers of research and development activity. Data were extracted from the US Food and Drug Administration website and stratified into one of 9 "subspecialty" groups: spine, trauma, hip arthroplasty, knee arthroplasty, shoulder, hand/elbow, foot/ankle, cement/filler/graft, and other. Descriptive statistics were used to analyze the data. Growth rates were calculated from trailing 3-year averages. During the study period, there were 9906 orthopedic 510(k) clearances and 1409 PMAs, of which 61 were for original PMA submissions. The preponderance of 510(k) clearances were for devices used in spine (36%) and trauma (30%) surgery, followed by hip (11%) and knee (8%) arthroplasty. Annual 510(k) clearances for spine and trauma devices grew by 232% and 44%, respectively, whereas annual hip and knee arthroplasty clearances declined. Paralleling these findings, the influx of new manufacturers of orthopedic devices was greatest for the trauma surgery (438), spine surgery (383), and cement/filler/graft (181) markets. Spinal surgery and orthopedic trauma have become leading priorities in orthopedic product development during the past two decades. Meanwhile, hip and knee arthroplasty products have proportionally become a smaller category of new devices over time. These findings demonstrate changing priorities within orthopedic innovation.

Clinical and radiographic outcomes following anatomic total shoulder arthroplasty utilizing an inset glenoid component at 2-year minimum follow-up: a dual center study.

BACKGROUND: Anatomic total shoulder arthroplasty (aTSA) is a successful and reproducible treatment for patients with painful glenohumeral arthritis. However, long-term outcomes using traditional onlay glenoid components have been tempered by glenoid loosening. Inset components have been proposed to minimize glenoid loosening by reducing edge-loading and opposite-edge lift-off forces with humeral translation. Successful short- and long-term outcomes have been reported while using inset glenoid implants. The current study is the largest study presenting a minimum of 2-year follow-up data following aTSA with an all-polyethylene inset glenoid component (Shoulder Innovations, Holland, MI, USA). METHODS: A dual center, retrospective review of patients undergoing aTSA using an Inset glenoid component by 2 fellowship-trained shoulder surgeons at 2 separate institutions from August, 2016, to August, 2019, was performed. Minimum follow-up was 2 years. Range of motion (ROM), visual analog scale (VAS) pain scores, Single Assessment Numeric Evaluation (SANE), and American Shoulder and Elbow Surgeons (ASES) scores were obtained. Radiographic outcomes, including central peg lucency and glenoid loosening, were assessed by 3 independent reviewers on the postoperative Grashey and axillary radiographs obtained at the final follow-up. RESULTS: Seventy-five shoulders were included for the final analysis. The mean age of the entire cohort was 64 (±11.4) years. Twenty-one (28%) glenoids were type A1, 10 (13.3%) were type A2, 13 (17.3%) were type B1, 22 (29.3%) were type B2, 6 (8%) were type B3, and 3 (4%) were type D. At a minimum follow-up of 24 months (mean: 28.7 months), a significant improvement in ROM in all planes was observed. Significant improvements in VAS (5.1-0.9, P < .001), SANE (39.5-91.2, P < .001), and ASES (43.7-86.6, P < .001) scores were observed. There were 4 (5.3%) cases of central peg lucency about the inset glenoid component and one (1.3%) case of glenoid loosening. No revisions were performed for glenoid loosening. CONCLUSION: At a minimum of 2 years postoperatively, there were significant improvements in ROM, VAS, SANE, and ASES scores with very low rates of central peg lucency and glenoid loosening in patients undergoing aTSA with an inset glenoid component. Further work is needed to determine the long-term benefit of this novel implant.

Patients who have undergone total shoulder arthroplasty prefer greater surgeon involvement in shared decision making.

BACKGROUND: There has been a shift in medical decision making from a paternalist model to a shared decision-making (SDM) approach, described as a patient-physician relationship where both parties collaborate to arrive on an evidence-based treatment regimen that best suits the patient's needs and values. However, there is a scarcity in evidence regarding SDM in shoulder arthroplasty. The purpose of this study was to evaluate overall patient preference for SDM and determine demographic and socioeconomic factors related to SDM preference in those undergoing shoulder arthroplasty. METHODS: Patients aged 40-89 years who had undergone a total shoulder arthroplasty were enrolled. Two-part questionnaires were administered collecting patient demographic information and SDM subscale scores postoperatively. Bivariate and multivariate regression models were used to determine factors associated with SDM Total and subscale scores. RESULTS: A total of 125 patients (53 male; mean age, 69.5 ± 10.4 years) who had undergone primary total shoulder arthroplasty were included. The mean Total SDM score was -2.24 ± 1.9 and the Preoperative, Operative, and Postoperative SDM subscale scores were -1.54 ± 2.0, -2.59 ± 2.2, and -2.48 ± 2.1, respectively, indicating a preference for SDM in the Preoperative subscale and surgeon-driven decision making in the total score and other 2 subscales. Multivariate regression models demonstrated a preference for surgeon decision making at both the 4-12-week postoperative period for the Preoperative subscale (odds ratio [OR] -1.03, 95% CI -2.0, -0.1, P = .039) and the 2-4-week postoperative period for the Operative subscale (OR -1.74, 95% CI -3.4, -0.1, P = .038) when compared to patients at the 2-week postoperative period. No other variables were significantly associated with any of the SDM subscale scores or Total SDM score. CONCLUSION: Patients reported a more passive role in the decision-making process with an overall preference for a surgeon-led approach in primary total shoulder arthroplasty. Patients preferred a shared decision-making approach in regard to preoperative considerations but indicated a significant preference for surgeon-led decision making regarding day of surgery decisions. There were no correlations between SDM scores and age, sex, race, income, education level, insurance type, or treating surgeon. Overall, patients demonstrated a predilection for an SDM approach for preoperative considerations, contrary to those decisions associated with the day of surgery and postoperative care.

Which Application Factors Are Associated With Outstanding Performance in Orthopaedic Surgery Residency?

BACKGROUND: Identifying ideal candidates for orthopaedic surgery residency is difficult. Data available for applicant selection are evolving; preclinical grades and the Alpha Omega Alpha (AOA) honors society are being phased out at some medical schools. Similarly, three-digit United States Medical Licensing Examination (USMLE) Step 1 scores have been eliminated. There is renewed interest in improving resident selection to provide a diverse, comprehensive educational opportunity that produces orthopaedic surgeons who are prepared for practice. QUESTIONS/PURPOSES: We sought to identify whether (1) academic achievements, (2) letters of recommendation, (3) research activity, and (4) miscellaneous factors available on Electronic Residency Application Service (ERAS) applications were associated with outstanding residency performance. METHODS: Ten faculty members (22% of all full-time faculty) with extensive educational involvement for at least 7 years, whose expertise covered all subspecialty departments at an urban, academic orthopaedic surgery residency program, were given an anonymous survey on the performance of the four most recent classes of residency graduates (24 residents). This survey was developed due to the lack of a validated residency outcomes tool or objective metrics for residency performance. The evaluated criteria were decided upon after discussion by a relatively large group of academic orthopaedic surgeons considering the factors most important for graduating orthopaedic residents. The faculty were selected based on their long-term knowledge of the residency, along with their diversity of specialty and backgrounds; there were no nonresponders. Faculty graded each resident on a scale from 1 to 10 (higher is better) on six criteria: surgical technical skills, research productivity, clinical knowledge, professionalism, personality, and fellowship match. The mean of the faculty ratings made by all faculty for all six criteria was calculated, producing the overall residency performance score. Factors available on each resident's ERAS application were then correlated with their overall residency performance score. Categorical ERAS factors, including AOA status, five or more honors in core clerkships, at least three exceptional letters of recommendation, collegiate athletics participation, expertise with a musical instrument, and research (6-year) track residents, were correlated with overall residency performance score via point biserial analysis. Continuous ERAS factors including USMLE Step 1 and Step 2 scores, number of publications before residency, number of research years before residency, medical school ranking, and number of volunteer experiences were correlated with overall residency performance score via Pearson correlation. USMLE Step 1 three-digit scores were evaluated despite their recent elimination because of their historic importance as a screening tool for residency interviews and for comparison to USMLE Step 2, which retains a three-digit score. Application factors with a p < 0.2 on univariate analysis (five or more honors in core clerkships, at least three exceptional letters of recommendation, research track residents) were included in a stepwise linear regression model with "overall residency performance score" as the outcome variable. All p values < 0.05 were considered significant. RESULTS: The mean overall residency performance score was 7.9 ± 1.2. Applicants with at least five honors grades in core clerkships had overall residency performance scores 1.2 points greater than those of their peers (95% confidence interval (CI) 0.3 to 2.0; p = 0.01, Cohen ƒ 2 = 0.2, representing a small effect size). ERAS applications including at least three exceptional letters of recommendation were associated with a 0.9-point increase in residency performance (95% CI 0.02 to 1.7; p = 0.046, Cohen ƒ 2 = 0.1, representing a small effect size). Participation in the residency research (6-year) track was associated with a 1-point improvement in residency performance (95% CI 0.1 to 1.9; p = 0.03, Cohen ƒ 2 = 0.2, again, representing a small effect size). Together, these three factors accounted for 53% of the variance in overall residency performance score observed in this study. CONCLUSION: Past clinical excellence, measured by core clerkship grades and exceptional letters of recommendation, is associated with slightly improved overall orthopaedic residency performance scores. Applicants meeting both criteria who also complete a research track residency may perform substantially better in residency than their counterparts, as these three factors accounted for half of all the variance observed in the current study. Although minimum requirements are necessary, traditionally used screening factors (such as USMLE scores, AOA status, medical school rank, and number of publications) may be of less utility in identifying successful future residents than previously thought. LEVEL OF EVIDENCE: Level III, therapeutic study.

Complete Isolated Ruptures of the Distal Biceps Brachii During Athletic Activity: A Systematic Review.

Complete, isolated ruptures of the distal biceps brachii sustained during athletic activities are uncommon. A systematic review of the literature was performed to identify complete distal biceps brachii tears experienced during athletic activities to determine injury prevalence, athletic activities/mechanisms responsible for injury and return to activity timing following operative management. A total of 10 studies, comprising 16 athletes undergoing surgery for 18 cases, were identified. Injuries were predominately associated with weightlifting. Injuries were treated utilizing a single incision in 56% of cases and primary repair performed in 89% of cases. Mean time to return to activity was 4.86 ± 1.14months. Athletes undergoing surgery ≤ 10 days following injury and those undergoing primary repair returned to activity significantly quicker. Isolated tears of the distal biceps remain uncommon during athletic activities, occurring primarily during weightlifting. Return to activity timing was not significantly delayed based on surgical approach, steroid use, or athlete age.

Mesenchymal Stem Cell Delivery via Topographically Tenoinductive Collagen Biotextile Enhances Regeneration of Segmental Tendon Defects.

BACKGROUND: Successful management of massive rotator cuff (RC) tendon tears represents a treatment challenge because of the limited intrinsic healing capacity of native tendons and the risk of repair failure. Biologic augmentation of massive RC tears utilizing scaffolds-capable of regenerating bulk tendon tissue to achieve a mechanically functional repair-represents an area of increasing clinical interest. PURPOSE: To investigate the histological and biomechanical outcomes after the use of a novel biologic scaffold fabricated from woven electrochemically aligned collagen (ELAC) threads as a suture-holding, fully load-bearing, defect-bridging scaffold with or without mesenchymal stem cells (MSCs) compared with direct repair in the treatment of critically sized RC defects using a rabbit model. STUDY DESIGN: Controlled laboratory study. METHODS: A total of 34 New Zealand White rabbits underwent iatrogenic creation of a critically sized defect (6 mm) in the infraspinatus tendon of 1 shoulder, with the contralateral shoulder utilized as an intact control. Specimens were divided into 4 groups: (1) gap-negative control without repair; (2) direct repair of the infraspinatus tendon-operative control; (3) tendon repair using ELAC; and (4) tendon repair using ELAC + MSCs. Repair outcomes were assessed at 6 months using micro-computed tomography, biomechanical testing, histology, and immunohistochemistry. RESULTS: Specimens treated with ELAC demonstrated significantly less tendon retraction when compared with the direct repair group specimens (P = .014). ELAC + MSCs possessed comparable biomechanical strength (178 ± 50 N) to intact control shoulders (199 ± 35 N) (P = .554). Histological analyses demonstrated abundant, well-aligned de novo collagen around ELAC threads in both the ELAC and the ELAC + MSC shoulders, with ELAC + MSC specimens demonstrating increased ELAC resorption (7% vs 37%, respectively; P = .002). The presence of extracellular matrix components, collagen type I, and tenomodulin, indicating tendon-like tissue formation, was appreciated in both the ELAC and the ELAC + MSC groups. CONCLUSION: The application of MSCs to ELAC scaffolds improved biomechanical and histological outcomes when compared with direct repair for the treatment of critically sized defects of the RC in a rabbit model. CLINICAL RELEVANCE: This study demonstrates the feasibility of repairing segmental tendon defects with a load-bearing, collagen biotextile in an animal model, showing the potential applicability of RC repair supplementation using allogeneic stem cells.

Restoration of the native humeral anatomy during stemless anatomic total shoulder arthroplasty: a radiographic comparison of intramedullary versus freehand resection.

BACKGROUND: During anatomic total shoulder arthroplasty (aTSA), the humeral head can be resected with or without the use of an intramedullary cutting guide, the former referred to as intramedullary (IM) resection and the latter referred to as freehand (FH) resection. Outcomes following aTSA are predicated upon the restoration of the native humeral anatomy, which can be more challenging with stemless implants. To date, no studies have determined which method of humeral head resection is superior in restoring native anatomy. Our purpose was to determine whether FH or IM resection was superior in restoring native anatomy during aTSA with stemless implants. METHODS: A review of all patients who underwent aTSA using the stemless Tornier Simpliciti Shoulder System at two academic institutions by two separate surgeons between January 2017 and June 2020 was performed. One surgeon at one institution performed stemless aTSA using the IM resection technique, while the second surgeon utilized the FH resection technique. Patients were excluded if they underwent surgery for an indication other than glenohumeral osteoarthritis, if they received a short-stem or standard-stem implant, or if they lacked adequate preoperative and postoperative Grashey radiographs. One hundred eleven patients across both institutions (51 IM, 60 FH) were included for the final radiographic assessment. The humeral head height (HH) and neck-shaft angle (NSA) were measured on preoperative and postoperative Grashey radiographs. The centers of rotation (CORs) were measured on postoperative Grashey radiographs. Patients were classified as having acceptable restoration of their native anatomy if the change (Δ) in COR or HH was ≤3 mm and ≤ 5 mm, respectively, or if the postoperative NSA was ≥130°. RESULTS: IM resection had the greatest acceptable restoration of COR (90.2% IM versus 70% FH, P = .009), HH (96.1% IM vs. 63.3% FH, P < .001), and NSA (96.1% IM vs. 78.3% FH, P = .006) relative to FH resection. The mean postoperative NSAs for the IM and FH cohorts were 134.4° (±2.1°) and 133.8° (±5.4°), respectively (P = .208). The mean ΔCORs for the IM and FH groups were 1.2 (±1.5) and 2.3 (±1.2) mm, respectively (P < .001). Finally, the mean ΔHHs for the IM and FH cohorts were 1.7 (±1.4) and 4.4 (±2.9) mm, respectively (P < .001). CONCLUSIONS: Restoration of the native humeral anatomy following stemless aTSA occurred at a significantly higher rate when using IM vs. FH resection.

Evaluating the Chase Utley Rule: The Association Between a Rule Change and Collision-Related Injuries in Major League Baseball.

Background: Major League Baseball (MLB) adopted a rule change in 2016 to reduce the number of collisions that occur when a player slides into a base. The effect of rule 6.01(j) has not been quantified, and it remains unknown if this rule change has led to improved player safety. Hypothesis: Rule 6.01(j) would be associated with a reduction in the number of collision-related injuries at second base. Study Design: Cohort study; Level of evidence, 3. Methods: Using data from the MLB Health and Injury Tracking System, we quantified the number of collision-related injuries for defensive (ie, fielding) players in the infield at the major and minor league levels between the 2010 and 2019 seasons. We compared the median number of collision-related injuries for defensive players in the infield from before (2010-2015) to after (2016-2019) the implementation of rule 6.01(j) and also calculated the difference in location of the median from the seasons before versus after the rule change. An additional 3 analyses were performed to support or contradict a conclusion that any observed reduction in injuries at the start of the 2016 season was likely caused by the adoption of rule 6.01(j). Results: The median number of collision-related injuries for defensive players at second base decreased from 58.5 to 37.5 injuries per season after the rule change, which was a 36% decrease (difference in location, 19.5 [95% CI, 5.0 to 31.0]; P = .019). In contrast, the median number of collision-related injuries at first base decreased by only 14.1%, from 49.5 before to 42.5 after the rule change (difference in location, -9.0 [95% CI, -4.0 to 18.0]; P = .16), and the median number of collision-related injuries per season at third base was unchanged at 15 per season. Conclusion: This rule change was associated with a decrease in the number of collision-related injuries, with the largest effect observed at second base, as expected.

Emergency Department Utilization Is Low After Outpatient Elective Rotator Cuff Repair.

INTRODUCTION: The purpose of this study was to establish emergency department (ED) utilization rate and reasons for presentation to the ED after outpatient rotator cuff repair (RCR) and determine preoperative predictors for these ED visits. METHODS: Patients who underwent outpatient RCR between 2014 and 2015 were retrospectively evaluated using the New York and Florida State Databases. The primary outcome was all-cause 7- and 30-day ED utilization rates. Reasons for presentation to the ED were recorded and stratified. Univariate and multivariate analyses were done to identify independent predictors of ED utilization. RESULTS: The 7- and 30-day ED visit rates were 3.2% and 5.0%, respectively. The most common cause for an ED visit after outpatient RCR at 7- and 30-days postoperatively were postoperative pain (29.0%) and GI complaints (16.3%), respectively. African American race (odds ratio [OD], 1.69; P < 0.001), Hispanic race (OD, 1.47; P = 0.005), and comorbid diagnoses of hypertension (OD, 1.51; P < 0.001), diabetes (OD, 1.58; P < 0.001), and/or schizophrenia (OD, 5.14; P < 0.001) were independent risk factors for an ED visit at up to 30 days postoperatively. Those with Medicare (OD, 2.01; P < 0.001) or Medicaid (OD, 2.61; P < 0.001) were more than twice as likely to present to the ED within 30 days than those with private health insurance. DISCUSSION: ED utilization after outpatient RCR is uncommon with postoperative pain as the most common chief concern for ED visits within the first 7 days and GI issues as the most common reason for ED encounters at up to 30 days postoperatively. Hypertension, diabetes, renal failure, liver disease, rheumatologic diseases, schizophrenia, depression, and Medicare and Medicaid insurance were independent predictors of ED encounters at up to 30 days postoperatively. Procedures done at freestanding surgery centers were protective against ED utilization. LEVEL OF EVIDENCE: Level III, Retrospective Cohort.

Effects of opioid-limiting legislation on postoperative opioid use in shoulder arthroplasty in an epidemic epicenter.

BACKGROUND: The current opioid epidemic in the United States has become a public health crisis with an estimated 150 daily deaths and nearly 47,000 opioid-related deaths in the United States in 2017 alone. Sensible prescriber practice changes have been a focus of policymakers to decrease the total number of narcotic pain medications in circulation. In the state of Ohio, opioid prescription limits for acute pain were enacted in August 2017. However, given the association of acute opioid exposure with long-term use and lack of assessment of these policies, there is an unmet need to evaluate the effects of similar legislation in Ohio on postoperative opioid dosing after shoulder arthroplasty. This study evaluates the effects of opioid prescription-limiting legislation in Ohio on postoperative opioid dosing in shoulder arthroplasty and assesses risk factors related to long-term opioid use. METHODS: All patients undergoing primary and revision shoulder arthroplasty over a 5-year period performed by a single surgeon were included. The pre-legislation (PRE) and post-legislation (POST) groups were defined as patients undergoing shoulder arthroplasty before August 31, 2017 and on or after August 31, 2017, respectively. The Ohio Automated Rx Reporting System was queried for controlled-substance prescriptions from 30 days preoperatively to 90 days postoperatively. Patients were designated as opioid tolerant if they had filled an opioid prescription within 30 days of surgery. A binary logistic regression analysis was applied to assess factors related to long-term opioid use. RESULTS: A total of 334 patients were categorized into 2 cohorts: PRE (n = 99) and POST (n = 235). Accounting for legislative effects, we observed significant reductions in cumulative morphine milligram equivalent (MME) dosing in the opioid-naive patients in the 7-day and 30-day postoperative periods (450.0 MMEs in PRE group vs. 210.0 MMEs in POST group, P < .001) and in the opioid-tolerant patients in the 7-day postoperative period (450.0 MMEs in PRE group vs. 250.0 MMEs in POST group, P = .001). Among the opioid-naive patients, the POST group had a significant MME reduction in the 90-day postoperative period relative to the PRE cohort (P < .001). Preoperative opioid tolerance and benzodiazepine tolerance were independent risk factors for increased MME dosing at 90 days postoperatively (P < .001 and P = .02, respectively). CONCLUSION: Opioid prescription-limiting legislation for acute pain in the state of Ohio is associated with a notable reduction in opioid MME dosing in the 90-day postoperative period after shoulder arthroplasty, particularly in opioid-naive patients in the first 30 days postoperatively. Preoperative opioid tolerance is correlated with significantly higher MME dosing postoperatively after shoulder arthroplasty.

Immunologic Contributions Following Rotator Cuff Injury and Development of Cuff Tear Arthropathy.

¼: Rotator cuff tear arthropathy (RCTA) describes a pattern of glenohumeral degenerative changes following chronic rotator cuff tears that is characterized by superior humeral head migration, erosion of the greater tuberosity of the humeral head, contouring of the coracoacromial arch to create a socket for the humeral head, and eventual glenohumeral arthritis. ¼: Acute and chronic inflammatory changes following rotator cuff tears are thought to contribute to cartilage damage, muscle fibrosis, and fatty infiltration in the glenohumeral joint. ¼: In vitro animal studies targeting various inflammatory modulators, including macrophages, insulin-like growth factor-I, and transforming growth factor-beta pathways, provide promising therapeutic targets to improve healing after rotator cuff tears. ¼: The role of platelet-rich plasma in the treatment and prevention of RCTA has been investigated, with conflicting results.

Clinical Outcomes of the Traditional Latarjet Versus the Congruent Arc Modification for the Treatment of Recurrent Anterior Shoulder Instability: A Meta-analysis.

BACKGROUND: Few studies have compared clinical outcomes between the traditional Latarjet procedure for anterior shoulder instability and the congruent arc modification to the Latarjet procedure. PURPOSE: To systematically evaluate the literature for the incidence of recurrent instability, clinical outcomes, radiographic findings, and complications for the traditional Latarjet procedure and the congruent arc modification and to compare results of each search. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review and meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We included studies published between January 1990 and October 2020 that described clinical outcomes of the traditional Latarjet and the congruent arc modification with a follow-up range of 2 to 10 years. The difference in surgical technique was analyzed using a chi-square test for categorical variables, while continuous variables were evaluated using a Student t test. RESULTS: In total, 26 studies met the inclusion criteria: 20 studies describing the traditional Latarjet procedure in 1412 shoulders, and 6 studies describing the congruent arc modification in 289 shoulders. No difference between procedures was found regarding patient age at surgery, follow-up time, Rowe or postoperative visual analog scores, early or late complications, return-to-sport timing, or incidence of improper graft placement or graft fracture. A significantly greater proportion of male patients underwent glenoid augmentation using the congruent arc modification versus traditional Latarjet (P < .001). When comparing outcomes, the traditional Latarjet procedure demonstrated a lower incidence of fibrous union or nonunion (P = .047) and broken, loose, or improperly placed screws (P < .001), and the congruent arc modification demonstrated improved outcomes with regard to overall return to sport (P < .001), return to sport at the same level (P < .001), incidence of subluxation (P = .003) or positive apprehension (P = .002), and revision surgery for recurrent instability (P = .027). CONCLUSION: Outcomes after the congruent arc modification proved at least equivalent to the traditional Latarjet procedure in terms of recurrent instability and return to sport, although early and late complications were equivalent. The congruent arc procedure may be an acceptable alternative to traditional Latarjet for the treatment of anterior shoulder instability with glenoid bone loss; however, long-term outcomes of this procedure are needed.

Oral Ketorolac as an Adjuvant Agent for Postoperative Pain Control After Arthroscopic Rotator Cuff Repair: A Prospective, Randomized, Controlled Study.

BACKGROUND: Arthroscopic rotator cuff repair (RCR) is associated with substantial postoperative pain. Oral narcotic agents are the preferred analgesic postoperatively. However, these agents are associated with several side effects and a potential for abuse. This study evaluates the efficacy of ketorolac as an adjunctive agent for postoperative pain control after arthroscopic RCR. METHODS: Adult patients undergoing arthroscopic RCR were prospectively enrolled and randomized to one of two groups. The control received our institution's standard-of-care pain protocol, including oxycodone-acetaminophen 5 to 325 mg on discharge. The ketorolac group received the standard-of-care protocol, intravenous ketorolac at the completion of the procedure, and oral ketorolac on discharge. Pain and functional outcome scores and narcotic utilization were recorded three times per day for the first 5 days after surgery. Repeat magnetic resonance imaging was done at least 6 months postoperatively. RESULTS: In our study, 39 patients were included for final analysis; the mean age of the cohort was 55.7 ± 10.6 years, and 66.7% of patients were male. No differences were observed in preoperative demographics, comorbidities, cuff tear morphology, and functional scores between the two groups. Over the first 5 days after surgery, patients in the ketorolac group consumed a mean of 10.6 fewer narcotic pills, a consumption reduction of 54.6% (19.42 versus 8.82, P < 0.001). No difference was observed in functional outcome scores at up to 6 weeks postoperatively between the two groups. No difference was observed in adverse events between the two groups with no reported cases of gastritis or gastrointestinal bleeding. Twenty-two of 39 patients underwent repeat magnetic resonance imaging at a mean of 7.9 months postoperatively, of which 5 (22%) demonstrated a retear of their rotator cuff. No significant difference was observed between the ketorolac and control groups in the rate of retear (P = 1.00). DISCUSSION: Adjunctive ketorolac substantially reduces narcotic utilization after arthroscopic RCR.

Evaluating the role of graft integrity on outcomes: clinical and imaging results following superior capsular reconstruction.

BACKGROUND: Superior capsular reconstruction (SCR) addresses massive, irreparable rotator cuff tears in young patients. The purpose of this study was to retrospectively evaluate clinical outcomes and graft integrity in patients following SCR. METHODS: Thirty-four consecutive patients undergoing SCR by 2 surgeons with minimum 2-year follow-up were identified. Functional outcomes were obtained, including Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), visual analog scale (VAS), and Single Assessment Numeric Evaluation (SANE) scores. Graft integrity was evaluated on magnetic resonance images (MRIs). RESULTS: Thirty-five shoulders in 34 patients were identified. Four patients underwent subsequent surgery. The mean preoperative scores were SST 21.6 ± 17.6, ASES 28.3 ± 10.1, SANE 50.6 ± 22.1, and VAS 6.6 ± 1.7. The mean postoperative outcomes were SST 79.1 ± 19.6, ASES 79.9 ± 17.4, SANE 74.3 ± 18.7, and VAS 1.5 ± 2.2. There was statistically significant improvement in SST, ASES, and VAS following SCR. MRI revealed graft failure in 62% (n = 13 of 21) of shoulders. Radiographic evidence of graft healing did not have any effect on SST, ASES, SANE, or VAS scores. CONCLUSION: Given the high rate of graft failure without a significant difference in clinical outcomes, graft healing after SCR might not be an independent predictor of success. The improved clinical improvement in patients undergoing SCR may be due to other known beneficial aspects of the procedure, including partial rotator cuff repair, débridement, and biceps management.

Opioid-prescribing patterns among shoulder and elbow surgeons: considerations for future prescription guidelines.

BACKGROUND: Although the achievement of adequate analgesia is critical to patient comfort and recovery following orthopedic procedures, no standard protocol exists to dictate the appropriate duration and quantity of narcotic prescription in the postoperative period. Therefore, the purpose of this survey was to determine patterns of opioid prescribing among orthopedic shoulder and elbow providers. METHODS: In March 2020, a survey was distributed through a LISTSERV to 989 members of the American Shoulder and Elbow Surgeons orthopedic society. Survey recipients were asked to describe their personal and practice characteristics. Additionally, they were asked to list their 3 most commonly performed procedures and, for each operation, to list which narcotic pain medication they most commonly prescribe postoperatively, along with the corresponding number of tablets typically given. Similarly, respondents were asked to record frequently recommended alternative strategies for postoperative pain control, factors influencing the respondents' prescribing practices, and methods of patient counseling regarding opioid use and disposal. RESULTS: A total of 177 providers responded to the survey. Across all selected procedures, Percocet (5 mg of oxycodone hydrochloride and 325 mg of acetaminophen) was the most commonly prescribed drug, with 21-30 tablets being the most commonly prescribed amount. The majority of surgeons (82%) indicated that previous opioid prescriptions influence their decision to prescribe opioids. Respondents most frequently reported patient age (48%) and duration of the patient's symptoms (32%) as additional influential factors. Most surgeons (93%) reported counseling their patients regarding the use of opioid medications. However, only 30% of surgeons reported providing information regarding how to dispose of unused opioids. In lieu of opioids, nearly all investigators reported the use of ice as a pain-relief strategy, with rest and the use of nonsteroidal anti-inflammatory drugs reported as other commonly recommended alternatives. Of 137 respondents who were aware of prescription guidelines, 21% reported using recommendations from the American Academy of Orthopaedic Surgeons, 21% used institutional policies, and 20% used personal guidelines, whereas the remaining respondents used other literature findings in their prescription decisions. Of particular concern, 21% of overall respondents were unaware of any type of guidelines. DISCUSSION: To prevent both misuse and abuse of opioid prescribing, this analysis serves as a starting point for the establishment of more consistent, evidence-based opioid prescription guidelines for surgical procedures on the shoulder and elbow. In addition to recommending safe, procedure-specific opioid dosages and standardizing pain management strategies, these guidelines should include effective methods of educating both providers and patients regarding the use of opioid medication.
