Race and Socioeconomic Status Are Associated With Inferior Patient-Reported Outcome Measures Following Rotator Cuff Repair.

PURPOSE: To investigate the impact social determinants of health (SDOH) have on National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive test scores and postoperative health care use in patients who undergo rotator cuff repair (RCR). METHODS: All patients who underwent RCR surgery by 3 shoulder and/or sports medicine fellowship-trained orthopaedic surgeons between July 2017 and January 2020 were included. The electronic medical record (EMR) was used to identify SDOH for each patient. PROMIS computer adaptive test measures of Upper Extremity function, Pain Interference, and Depression were completed preoperatively and postoperatively (6 months and 1 year). Postoperative health care use (clinical visits, virtual encounters, imaging encounters, and physical therapy visits) were recorded as well. Univariate associations, multiple linear regressions, and Wilcoxon rank-sum tests were used to analyze mean differences between patient groups based on SDOH. RESULTS: Three hundred thirty-eight patients who underwent RCR were included. Patients who were Black, in lower median household income quartiles, had public insurance, and female reported lower PROMIS scores compared with their counterparts. Smokers and White patients attended fewer postoperative office visits whereas Black patients had more physical therapy and nonvisit encounters compared with their respective counterparts. CONCLUSIONS: Black race and lower socioeconomic status are associated with worse function and pain outcomes post-RCR compared with White race. Similarly, Black race and positive smoking status are associated with differential use of health care following RCR. Further attention may be required for these patients to address health care disparities. LEVEL OF EVIDENCE: III, retrospective cohort study.

Editorial Commentary: Baseball Catchers Who Throw From a Squatted Position May Reduce Medial Elbow Torque by Stretching Exercise to Increase Passive Internal Rotation of the Throwing-Side Hip.

Youth baseball pitchers who also play catcher are at nearly 3-fold increased risk of developing a shoulder or elbow injury throughout the course of a season. The risk of injury has been largely attributed to the increased workload from a greater overall number of throws. In addition, throws performed by catchers are often performed in the squatting or kneeling position, which is radically different from all other positions. Fortunately, recent research shows no difference in medial elbow torque between squatting and standing throws a standard distance from home plate to the pitcher and also shows that greater passive internal rotation of the hip on the throwing side is protective against loads on the medial elbow when throwing from the squatting position. Improving passive hip range of motion through stretching exercises may prevent injury in young baseball catchers.

Social Determinants of Health Influence Access to Care and Outcomes in Patients Undergoing Anterior Cruciate Ligament Reconstruction: A Systematic Review.

PURPOSE: To investigate the impact social determinants of health (SDOH) have on accessing orthopaedic treatment after an anterior cruciate ligament injury, as well as patient-reported and surgical outcomes after anterior cruciate ligament reconstruction (ACLR). METHODS: A systematic search of the PubMed, MEDLINE, Epub Ahead of Print, Embase, and Web of Science databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies that reported at least 1 SDOH and its effect on patient-reported outcomes or surgical outcomes after anterior cruciate ligament reconstruction. Our search identified 937 studies. After eliminating 273 duplicates, 2 authors screened 664 articles on the basis of title and abstract. After this initial screening, 76 studies were evaluated for data extraction. Studies were categorized based on the social determinant(s) of health reported. RESULTS: Twenty-two articles published between 2002 and 2020 were included in this study, encompassing 15 retrospective cohort studies, 3 prospective cohort studies, 3 cross-sectional studies, and 1 case-control study from 9 journals across 3 countries. Of these articles, 9 investigated race/ethnicity, 8 investigated insurance status, 4 investigated income, 5 investigated education level, 2 investigated employment status, and 5 investigated socioeconomic status. Reported outcomes included time to treatment, concomitant knee injury, patient-reported outcome measurement scores, postoperative complications, need for additional surgery, and postoperative healthcare utilization. CONCLUSIONS: Certain SDOH, including black race, Hispanic ethnicity, public health insurance, and lower socioeconomic status contribute to a delay in access to care, which may result in increased severity of concomitant knee injuries encountered at the time of anterior cruciate ligament reconstruction and inferior outcomes.

Preoperative Opioid Use Is Associated With Inferior Patient-Reported Outcomes Measurement Information System Scores Following Rotator Cuff Repair.

PURPOSE: To determine the influence of preoperative opioid use on Patient-Reported Outcomes Measurement Information System (PROMIS) scores pre- and postoperatively in patients undergoing arthroscopic rotator cuff repair (RCR). METHODS: A retrospective review of all RCR patients aged >18 years old was performed. PROMIS pain interference ("PROMIS PI"), upper extremity function ("PROMIS UE"), and depression ("PROMIS D") scores, were reviewed. These measures were collected at preoperative, 6-month, and 1-year postoperative time points. A prescription drug-monitoring program was queried to track opioid prescriptions. Patients were categorized as chronic users, acute users, and nonusers based on prescriptions filled. Comparison of means were carried out using analysis of variance and least squares means. Effect sizes and 95% confidence intervals were calculated. RESULTS: In total, 184 patients who underwent RCR were included. Preoperatively, nonusers (n = 92) had superior PROMIS UE (30.6 vs 28.9 vs 26.1; P < .05) and PI scores (61.5 vs 64.9 vs 65.3; P < .001) compared with acute users (n = 65) and chronic users (n = 27), respectively. At 6 months postoperatively; nonusers demonstrated significantly greater PROMIS UE (41.7 vs 35.6 vs. 33.5; P < .001), lower PROMIS D (41.6 vs 45.8 vs 51.1; P < .001), and lower PROMIS PI scores (50.7 vs 56.3 vs 58.1; P < .01) when compared with acute and chronic users, respectively. Nonusers had lower PROMIS PI (47.9 vs 54.3 vs 57.4; P < .0001) and PROMIS D (41.6 vs 48.3 vs 49.2; P = .0002) scores compared with acute and chronic users at 1-year postoperatively. Nonusers experienced a significantly greater magnitude of improvement in PROMIS D 6 months postoperatively compared with chronic opioid users (-5.9 vs 0.0; P < .01). CONCLUSIONS: Patients undergoing RCR demonstrated superior PROMIS scores pre- and postoperatively if they did not use opioids within 3 months before surgery. LEVEL OF EVIDENCE: III, retrospective comparative trial.

Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Instruments Compare Favorably With Legacy Patient-Reported Outcome Measures in Upper- and Lower-Extremity Orthopaedic Patients: A Systematic Review of the Literature.

PURPOSE: To compare Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) with traditional ("legacy") patient-reported outcome measures (PROMs) in regard to correlations, ease of use, and quality criteria for upper (UE) and lower extremity (LE) orthopaedic conditions. METHODS: A systematic search of the PubMed/MEDLINE database was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify published articles that referenced the various PROMIS PF measures. Two authors independently reviewed selected studies. The search returned 857 studies, 85 of which were selected for independent review by 2 authors. Of these, 54 were selected for inclusion. Mixed linear models were performed to assess for differences between legacy PROMs and PROMIS measures. RESULTS: The combined sample size of all included studies yielded 6,074 UE and 9,366 LE patients. Overall, PROMIS PF measures demonstrated strong correlations with legacy PROMs among UE (weighted Pearson correlation, 0.624, standard error [SE] = 0.042; weighted Spearman correlation, 0.566, SE = 0.042) and LE patients (weighted Pearson correlation, 0.645, SE = 0.062; weighted Spearman correlation, 0.631, SE = 0.041). PROMIS PF questionnaires completed by UE patients had fewer questions than legacy PROMs (5.9 vs 17.7, P = .0093) and were completed in less time (90.5 vs 223.8 seconds, P = .084). PROMIS PF questionnaires completed by LE patients had fewer questions than legacy PROMs (4.81 vs 15.33, P < .001) and were completed in less time (63.6 vs 203.2 seconds, P = .0063). The differences for the reliability measures were not significant. CONCLUSIONS: PROMIS PF scores correlate strongly with commonly used legacy PROMs in orthopaedics, particularly in UE and LE patients. PROMIS PF forms can be administered efficiently and to a broad patient population while remaining highly reliable. Therefore, they can be justified for standardized use among orthopaedic patients with UE and LE conditions, improving the ability to aggregate and compare outcomes in orthopaedic research.

Time-Driven Activity-Based Costing Accurately Determines Bundle Cost for Rotator Cuff Repair.

PURPOSE: The purpose of this study was to determine the cost of the episode of care for primary rotator cuff repair (RCR) from day of surgery to 90 days postoperatively using the time-driven activity-based costing (TDABC) method. The secondary purpose of this study was to identify the main drivers of cost for both phases of care. METHODS: This retrospective case series study used the TDABC method to determine the bundled cost of care for an RCR. First, a process map of the RCR episode of care was constructed in order to determine drivers of fixed (i.e., rent, power), direct variable (i.e., healthcare personnel), and indirect costs (i.e., marketing, building maintenance). The study was performed at a Midwestern tertiary care medical system, and patients were included in the study if they underwent an RCR from January 2018 to January 2019 with at least 90 days of postoperative follow-up. In this article, all costs were included, but we did not account for fees to provider and professional groups. RESULTS: The TDABC method calculated a cost of $10,569 for a bundled RCR, with 76% arising from the operative phase and 24% from the postoperative phase. The main driver of cost within the operative phase was the direct fixed costs, which accounted for 35% of the cost in this phase, and the largest contributor to cost within this category was the cost of implants, which accounted for 55%. In the postoperative phase of care, physical therapy visits were the greatest contributor to cost at 59%. CONCLUSION: In a bundled cost of care for RCR, the largest cost driver occurs on the day of surgery for direct fixed costs, in particular, the implant. Physical therapy represents over half of the costs of the episode of care. Better understanding the specific cost of care for RCR will facilitate optimization with appropriately designed payment models and policies that safeguard the interests of the patient, physician, and payer.

Trends in Patient-Reported Outcomes Measurement Information System Scores Exist Between Day of Surgical Scheduling and Day of Surgery.

PURPOSE: To examine trends in Patient-Reported Outcome Measurement Information System (PROMIS) scores among orthopedic sports medicine patients undergoing surgery who completed PROMIS forms both in the ambulatory (preoperative) setting at the time of surgical scheduling, as well as on the day of surgery (perioperative) prior to their procedure. METHODS: Consecutive patients undergoing various sports medicine-related surgeries were recruited. Patients were included if they were scheduled for surgery and completed preoperative PROMIS on the day of surgical scheduling and on the day of surgery. Patients were excluded if they refused the questionnaire or had been administered perioperative anesthesia, which would interfere with questionnaire completion. Paired samples t-tests were run between preoperative and perioperative PROMIS scores to determine statistical significance. RESULTS: 153 patients were included with an average age of 46.5 years. The average (SD) time between completion of PROMIS questionnaires was 46.5 (44.4) days. The absolute value change in scores between preoperative and perioperative visits was 4.09 for PROMIS UE, 3.59 for PROMIS PF, 3.67 for PROMIS PI, and 4.13 for PROMIS D. The overall net change of scores between preoperative and perioperative visits were -.57 for PROMIS UE CAT, .16 points for PROMIS PF CAT, -.85 points for PROMIS PI CAT, and -2.14 points for PROMIS D CAT. Statistically significant differences in preoperative and perioperative PROMIS PI (P =.042) and PROMIS D (P =.004) scores were found. CONCLUSIONS: Health states-as measured by PROMIS CAT forms completed among patients undergoing orthopedic surgery-can either improve or worsen preoperatively between the time of administration in both the ambulatory and perioperative setting. Despite the existence of these preoperative trends, it is important to consider patient and surgery-specific causes, such as the anatomic region, type of surgical intervention, and timing of preoperative PROMIS administration.

Risk factors for failure to achieve minimal clinically important difference and significant clinical benefit in PROMIS computer adaptive test domains in patients undergoing rotator cuff repair.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) has emerged as a valid and efficient means of collecting outcomes in patients with rotator cuff tears. The purpose of this study was to establish threshold score changes to determine minimal clinically important difference (MCID) and substantial clinical benefit (SCB) in PROMIS computer adaptive test (CAT) scores following rotator cuff repair (RCR). Additionally, we sought to identify potential risk factors for failing to achieve MCID and SCB. METHODS: Patients undergoing arthroscopic RCR were identified over a 24-month period. Only patients who completed both preoperative and postoperative PROMIS CAT assessments were included in this cohort. PROMIS CAT forms for upper extremity physical function (PROMIS-UE), pain interference (PROMIS-PI), and depression (PROMIS-D) were used with a minimum of 1.5-year follow-up. Statistical analysis was performed to determine threshold score changes to determine anchor-based MCID and SCB, as well as risk factors for failure to achieve significant clinical improvement following surgery. RESULTS: Of 198 eligible patients, 168 (84.8%) were included in analysis. ΔPROMIS-UE values of 5.8 and 9.7 (area under the curve [AUC] = 0.906 and 0.949, respectively) and ΔPROMIS-PI values of -11.4 and -12.9 (AUC = 0.875 and 0.938, respectively) were identified as threshold predictors of MCID and SCB achievement. On average, 81%, 65%, and 55% of patients achieved MCID for PROMIS-UE, PROMIS-PI, and PROMIS-D whereas 71%, 61%, and 38% of patients in the cohort, respectively, achieved SCB. MCID achievement in PROMIS-UE significantly differed according to risk factors, including smoking status (likelihood ratio [LR]: 9.8, P = .037), tear size (LR: 10.4, P < .001), distal clavicle excision (LR: 6.1, P = .005), and prior shoulder surgery (LR: 19.2, P < .001). Factors influencing SCB achievement for PROMIS-UE were smoking status (LR: 9.3, P = .022), tear size (LR: 8.0, P = .039), and prior shoulder surgery (11.9, P < .001). Significantly different rates of MCID and SCB achievement in PROMIS-PI for smoking status (LR: 7.0, P = .030, and LR: 5.2, P = .045) and prior shoulder surgery (LR: 9.1, P = .002, and LR: 7.4, P = .006) were also identified. DISCUSSION AND CONCLUSION: The majority of patients showed clinically significant improvements that exceeded the established MCID for PROMIS-UE and PROMIS-PI following RCR. Patients with larger tear sizes, a history of prior shoulder surgery, tobacco users, and those who received concomitant distal clavicle excision were at risk for failing to achieve MCID in PROMIS-UE. Additionally, smokers and patients who underwent prior shoulder surgery demonstrated significantly lower improvements in pain scores following surgery.

Impact of the COVID-19 pandemic on shoulder arthroplasty: surgical trends and postoperative care pathway analysis.

BACKGROUND: COVID-19 triggered disruption in the conventional care pathways for many orthopedic procedures. The current study aims to quantify the impact of the COVID-19 pandemic on shoulder arthroplasty hospital surgical volume, trends in surgical case distribution, length of hospitalization, posthospital disposition, and 30-day readmission rates. METHODS: This study queried all Medicare (100% sample) fee-for-service beneficiaries who underwent a shoulder arthroplasty procedure (Diagnosis-Related Group code 483, Current Procedural Terminology code 23472) from January 1, 2019, to December 18, 2020. Fracture cases were separated from nonfracture cases, which were further subdivided into anatomic or reverse arthroplasty. Volume per 1000 Medicare beneficiaries was calculated from April to December 2020 and compared to the same months in 2019. Length of stay (LOS), discharged-home rate, and 30-day readmission for the same period were obtained. The yearly difference adjusted for age, sex, race (white vs. nonwhite), Centers for Medicare & Medicaid Services Hierarchical Condition Category risk score, month fixed effects, and Core-Based Statistical Area fixed effects, with standard errors clustered at the provider level, was calculated using a multivariate analysis (P < .05). RESULTS: A total of 49,412 and 41,554 total shoulder arthroplasty (TSA) cases were observed April through December for 2019 and 2020, respectively. There was an overall decrease in shoulder arthroplasty volume per 1000 Medicare beneficiaries by 14% (19% reduction in anatomic TSA, 13% reduction in reverse shoulder arthroplasty, and 3% reduction in fracture cases). LOS for all shoulder arthroplasty cases decreased by 16% (-0.27 days, P < .001) when adjusted for confounders. There was a 5% increase in the discharged-home rate (88.0% to 92.7%, P < .001), which was most prominent in fracture cases, with a 20% increase in discharged-home cases (65.0% to 73.4%, P < .001). There was no significant change in 30-day hospital readmission rates overall (P = .20) or when broken down by individual procedures. CONCLUSIONS: There was an overall decrease in shoulder arthroplasty volume per 1000 Medicare beneficiaries by 14% during the COVID-19 pandemic. A decrease in LOS and increase in the discharged-home rates was also observed with no significant change in 30-day hospital readmission, indicating that a shift toward an outpatient surgical model can be performed safely and efficiently and has the potential to provide value.

Changes in Patient Reported Outcome Measure Scores From Initial Presentation to Day-of-Surgery in Patients Undergoing Hip and Knee Arthroplasty.

BACKGROUND: It is not well understood how patient reported outcome measures (PROMs) change from initial presentation to day-of-surgery (DOS). This study sought to quantify preoperative PROM changes for hip and knee arthroplasty patients. METHODS: A retrospective review was performed on primary total hip, total knee, and partial knee arthroplasty patients from October 2020 through January 2021. Trends in preoperative Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR), and Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) scores were compared using scores at initial presentation in the ambulatory clinic and at a time near the date-of-surgery. A total of 497 patients possessed 2 preoperative PROMIS-PF (497/497), HOOS-JR (152/497), or KOOS-JR (258/497) surveys. RESULTS: There was no significant statistical difference in mean PROM scores between initial presentation and DOS PROMIS-PF or HOOS-JR scores. Only KOOS-JR demonstrated a significant statistical difference of 2 ± 14 (P = .002) when comparing initial versus preoperative scores. Partial knee arthroplasty patients saw a strong positive correlation (r = 0.77) between initial PROMIS-PF and DOS scores. However, mean absolute value changes on an individual level were 4 ± 4, 11 ± 39, and 11 ± 10 for PROMIS-PF, HOOS-JR, and KOOS-JR, respectively, indicating the presence of meaningful patient-level score changes as based on previously published anchor-based minimal clinically important differences. CONCLUSION: PROMs collected during the preoperative period demonstrated wide variability at an individual level, but not at a population level. Collection at both time points may be necessary in order to understand the clinical impact of surgery on these patients.

Time-Driven Activity-Based Costing Provides a Lower and More Accurate Assessment of Costs in the Field of Orthopaedic Surgery Compared With Traditional Accounting Methods.

PURPOSE: To analyze the implementation and benefits of time-driven activity-based costing (TDABC) in the field of orthopaedic surgery. METHODS: We performed a search of PubMed, Google Scholar, and Embase in March 2020, using the following terms: "Time-Driven Activity-Based Costing," "TDABC," "Orthopaedic Surgery," and "Cost." Then we selected the studies that used the TDABC methodology to generate costs for a particular aspect of orthopaedic surgery. The included studies were divided into the following 5 main categories for ease of analysis: joint arthroplasty, trauma, hand, electronic medical record (EMR) implementation, and pediatric. We analyzed the overall ability of TDABC in the field of orthopaedic surgery, compared to the standard costing methods. RESULTS: We included a total of 19 studies that implemented the TDABC methodology to generate a cost, which was compared to traditional accounting methods. The orthopaedic subspecialty with the most amount of TDABC implementation has been the field of joint arthroplasty. In these studies, the authors have noted that TDABC has provided a more granular breakdown of costs and has calculated a lower cost compared with traditional accounting methods. CONCLUSION: TDABC is a powerful cost analysis method that has demonstrated benefit over the activity-based costing (ABC) approach in determining a lower and more accurate cost of orthopaedic procedures. Furthermore, the TDABC method generates an average cost reduction of $10,000 and $12,000 for total hip arthroplasty and total knee arthroplasty, respectively. CLINICAL RELEVANCE: TDABC can allow health care administration to better determine and understand the cost drivers of particular orthopaedic procedures at their institutions. With improved estimates on the true cost of an activity, hospital administrators and department chairs can adjust to ensure cost-effective, patient-centered health care.

Pain Is the Primary Factor Associated With Satisfaction With Symptoms for New Patients Presenting to the Orthopedic Clinic.

PURPOSE: The purpose of the current study was to (1) determine the percentage of new orthopedic patients reporting their symptoms to be acceptable at presentation, as measured by the Patient Acceptable Symptom State (PASS) question, and (2) evaluate whether patient-reported outcome measures (PROMs), including Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) or Upper Extremity, Pain Interference (PI), and Depression (D), or sociodemographic factors are associated with acceptable symptoms at presentation. METHODS: Between February 7, 2020, and March 16, 2020, new orthopedic patients who completed PROMs were identified. Patient records were reviewed for those who also completed the PASS question, a yes/no question about whether a patient's current symptom state is satisfactory. Bivariate analysis was conducted to compare patient characteristics, such as area deprivation index (ADI), between those reporting acceptable symptoms and those who did not. Multivariable logistic regression models were used to determine factors associated with acceptable symptoms at presentation. RESULTS: A total of 570 patients were included, with one-fourth (n = 143 [25%]) reporting acceptable symptoms at presentation. In multivariable regression analysis, only pain, as measured by the PROMIS PI, was associated with acceptable symptoms at presentation (non-upper extremity patient regression: PROMIS PI: odds ratio [OR], 0.84; 95% confidence interval [CI], 0.79-0.90, P < .01; upper extremity patient regression: PROMIS PI: OR, 0.91; 95% CI, 0.85-0.98, P < .01). In both multivariable regression analyses, insurance type (private, Medicare, Medicaid, other), visit subspecialty (sports, hand, joints, foot and ankle, spine, other), PROMIS PF, PROMIS D, and national ADI were not associated with acceptable symptoms at presentation (all P > .05). CONCLUSIONS: One-fourth of new orthopedic patients reported their symptoms to be acceptable at presentation. Of those who considered their symptom state unsatisfactory, pain-not functional status, mental health, or sociodemographic factors-was the primary determinant. LEVEL OF EVIDENCE: Level III, diagnostic.

Preoperative Patient-Centric Predictors of Postoperative Outcomes in Patients Undergoing Arthroscopic Meniscectomy.

PURPOSE: To determine the minimal clinically important difference (MCID) using Patient-Reported Outcome Measurement Information System (PROMIS) computer-adaptive testing assessments in patients undergoing arthroscopic partial meniscectomy. The secondary purpose was to identify which preoperative patient factors are associated with MCID achievement. METHODS: Three PROMIS computer-adaptive testing assessments (Physical Function [PF], Pain Interference [PI], and Depression [D]) were administered to all patients presenting to 1 of 2 board-certified, sports medicine orthopaedic surgeons. Patients with Current Procedural Terminology codes of 29880 or 29881 were chart reviewed for a host clinical and demographic factors. PROMIS scores were assessed for improvement and patient characteristics were assessed for influence on any improvement. MCID was calculated according to the distribution methodology and receiver operating characteristics were used to assess preoperative scores predictive ability. RESULTS: In total, 166 patients met inclusion criteria (58 exclusions). Postoperative PROMIS-PF (45.6), PROMIS-PI (54.6), and PROMIS-D (44.1) significantly improved at least 3 months after surgery when compared with baseline (P = .002). MCID values for PROMIS-PF, PROMIS-PI, and PROMIS-D were 3.5, 3.3, and 4.4, respectively. Individuals with PROMIS-PF scores below 34.9 yielded an 82% probability of achieving MCID, while PROMIS-PI scores above 67.5 yielded an 86% probability of achieving MCID and a cutoff of 58.9 for PROMIS-D yielded a 60% probability of achieving MCID, with 90% specificity. CONCLUSIONS: PROMIS scores, obtained preoperatively, were shown to be valid predictors of postoperative clinical improvement in patients undergoing meniscectomy. Our findings suggest that patients with physical function scores of 34.9 or less have an increased probability of reaching a minimal clinically important difference. Similarly, patients with pain interference scores of 67.5 and above have increased probability of reaching MCID for pain interference. These cutoffs may be used by physicians to aid in the counseling of patients considering arthroscopic meniscectomy. LEVEL OF EVIDENCE: IV, Case Series.

Patients With Preoperative Clinical Depression Symptomology Experience Significant Improvements in Postoperative Pain, Function, and Depressive Symptoms Following Rotator Cuff Repair.

PURPOSE: To determine the impact of clinical depression on outcomes after rotator cuff repair (RCR), as measured by Patient-Reported Outcomes Measurement Information System (PROMIS) Computer Adaptive Test (CAT) health domains. METHODS: RCR patients were given PROMIS CAT assessments for physical function (PROMIS UE), pain interference (PROMIS PI), and depression (PROMIS D) during preoperative and postoperative clinic visits. PROMIS D scores ≥55 correlate with mild clinical depression; thus patients with PROMIS D scores ≥ 55 were placed in the clinical depression (CD) group, whereas patients with scores <55 were placed in the "no clinical depression" (NCD) group. Categorical variables were compared at preoperative and postoperative (6 months and ≥1 year) timepoints using χ2 tests. Continuous variables were compared using Student's t-tests. RESULTS: Of the 340 RCR patients included in this study, 65 (19.1%) were found to have mild clinical depression preoperatively, with that number being reduced to 23 (6.8%) at 6 months and 19 (5.6%) at ≥1 year after surgery. Compared with preoperative PROMIS scores, CD patients had significant postoperative improvements at 6 months and ≥1 year in mean PROMIS UE (26.7 vs 35.5 vs 38.9; P < .001) and PROMIS PI (67.6 vs 56.7 vs 56.4; P < .001). NCD patients had similar postoperative improvements at 6 months and ≥1 year in mean PROMIS UE (30.8 vs 38.6 vs 46.9; P < .001) and PROMIS PI (61.7 vs 53.0 vs 47.6; P < .001). The improvement in PROMIS scores was similar for the CD and NCD groups in both PROMIS UE (12.2 vs 16.1, respectively) and PROMIS PI (-11.2 vs -14.1, respectively). CONCLUSION: Despite starting with worse PROMIS UE and PROMIS PI scores, patients undergoing RCR with symptoms of CD experienced significant improvement in function, pain, and depressive symptoms. Preoperative depression should not be a contraindication to arthroscopic RCR in patients who are otherwise appropriate operative candidates.

Elbow Torque Is Reduced in Asymptomatic College Pitchers With Elbow Laxity: A Dynamic Ultrasound Study.

PURPOSE: To determine the relation between medial elbow torque, as measured by wearable sensor technology, and adaptations of the medial elbow structures on dynamic ultrasound imaging in asymptomatic collegiate pitchers. METHODS: Thirty-four pitchers from National Collegiate Athletic Association Division II universities were eligible for preseason testing. The exclusion criteria included age younger than 18 years, history of surgery, non-pitcher, or current restrictions. Pitchers were fitted with a wearable sensor sleeve that recorded elbow torque, arm slot, arm speed, and arm rotation. Pitchers threw 5 fastballs in a standardized manner off the mound at game-speed effort. They also underwent dynamic ultrasound imaging of the elbow by a musculoskeletal sonographer, with standardized valgus loading. Images were deidentified, and measurements of the ulnar collateral ligament (UCL) and ulnohumeral joint space (UHJS), to assess elbow laxity, were performed by a musculoskeletal radiologist. RESULTS: The final analysis included 28 pitchers with an average age of 20.1 years (standard deviation, 1.3 years; range, 18-23 years) and playing experience of 15.3 years (standard deviation, 1.8 years; range, 11-19 years). The dominant UCL thickness (P < .001), loaded UHJS (P = .039), and delta UHJS (P < .001) were significantly greater than the nondominant measurements. An inverse correlation was found between loaded UHJS and medial elbow torque (r = -0.4, P < .001). Additionally, every 1-mm increase in UHJS significantly reduced medial elbow torque by 2.27 Nm (P = .032) and arm slot by 8.8° (P = .019) and increased arm rotation by 5.3° (P = .043). Pitchers with a loaded UHJS of 4.4 mm or greater and delta UHJS of 1.25 mm or greater had significantly reduced medial elbow torque (P < .001). Pitchers with a UCL thickness of 1.65 mm or greater had significantly increased medial elbow torque (47.4 Nm vs 44.8 Nm, P = .006). CONCLUSIONS: Pitchers with increased dynamic elbow laxity were found to experience reduced medial elbow torque while pitching. Additionally, pitchers with greater UCL thickness on ultrasound were found to experience increased medial elbow torque while pitching. This study's findings suggest a relation between anatomic adaptations found on ultrasound of the pitching elbow and medial elbow torque. LEVEL OF EVIDENCE: Level II, prospective cohort study.

Technical Pearls for Shoulder Instability.

Glenohumeral instability is one of the most common conditions of the upper extremity, especially in athletes and active individuals. Over the past two decades, there has been a transformation of surgical treatment from traditionally open repair/reconstruction to arthroscopic management. This has especially been true with management of both anterior and posterior instability without significant bone loss. In this setting, and in certain patient populations (eg, contact/collision athletes), arthroscopic treatment may not be sufficient. Therefore, open techniques, such as coracoid bone transfer, also occupy an important role in management of glenohumeral instability. The goal of this review is to provide technical "pearls" in management of glenohumeral instability. Specifically, the review will highlight treatments such as arthroscopic anterior and posterior instability repair, posterior glenoid bone augmentation, and open coracoid transfer (Latarjet) for anterior instability with bone loss. We will also review management of complications related to coracoid transfer.

Establishing and comparing reference preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) scores in patients undergoing shoulder surgery.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) has become increasingly popular among orthopedic surgeons treating shoulder pathology. Despite this, there have been few studies that have described and compared preoperative reference scores for specific shoulder surgical procedures. The primary purpose of this study was to establish and compare baseline preoperative PROMIS scores for 3 common types of shoulder surgery: rotator cuff repair (RCR), total shoulder arthroplasty (TSA), and labral repair (LR). The secondary goal was to stratify these operative groups by diagnosis and compare preoperative PROMIS scores. METHODS: In this cross-sectional study, adult and pediatric patients who underwent surgery for either RCR, TSA, or LR were included. PROMIS-Upper Extremity (UE), PROMIS-Pain Interference (PI), and PROMIS-Depression (D) scores that were collected at each patient's preoperative visit were reviewed. Continuous and categorical variables were compared between operative groups using analysis of variance and χ2 or Fisher exact tests, respectively. Multivariable general linear models were used to identify significant independent predictors of PROMIS scores when controlling for age, sex, and body mass index. RESULTS: A total of 413 patients were included in the study: 272 in the RCR group, 84 in the TSA group, and 57 in the LR group. The average PROMIS-UE score was 39.8 in the LR group vs. 29.9 in the RCR group (P < .001) and 29.6 in the TSA group (P < .001). There was no difference between the mean RCR and TSA PROMIS-UE scores (P = .93). The average PROMIS-PI score was 56.6 in the LR group vs. 62.8 in the RCR group (P < .001) and 63.9 in the TSA group (P < .001). There was no difference between RCR and TSA PROMIS-PI scores (P = .09). The average PROMIS-D score was 43.5 in the LR group vs. 47.7 in the RCR group (P = .004) and 50.3 in the TSA group (P < .001). The TSA group had a higher mean PROMIS-D score than the RCR group (P = .03). For PROMIS-UE scores, age and body mass index were not found to be significant independent predictors (P = .98 and P = .88, respectively). For PROMIS-PI scores, age, body mass index, and sex were not found to be significant independent predictors (P = .31, P = .81, and P = .48, respectively). CONCLUSION: Patients undergoing shoulder LR had higher preoperative function scores and lower pain interference and depression scores than those undergoing TSA and RCR. These baseline PROMIS scores should be taken into consideration when tracking a patient's outcomes after surgery, as a certain score could mean drastically different functional and pain outcomes depending on the underlying pathology.

The relationship between shoulder range of motion and elbow stress in college pitchers.

HYPOTHESIS: College pitchers with increased external rotation gain (ERG) produce increased medial elbow torque (elbow stress) whereas those with reduced total rotational range of motion (ROM) have reduced medial elbow torque during pitching. METHODS: Pitchers were recruited from 3 college baseball teams. Players with prior injury or on pitching restrictions because of pain were excluded. Players were evaluated within 2 weeks before their first game of the season. Pitchers completed an intake survey, and shoulder and arm measurements were taken. Pitchers were fitted with a baseball sleeve that included a sensor at the medial elbow. The sensor calculated elbow torque, arm speed, arm slot, and shoulder rotation for each pitch, while a radar gun measured peak ball velocity. After adequate warm-up, pitchers threw 5 fastballs in a standardized manner off the mound at game-speed effort. The primary outcome evaluated the relationship between shoulder ROM and medial elbow torque. Additional outcomes evaluated pitcher characteristics and demographic characteristics in the context of shoulder ROM. RESULTS: Twenty-eight pitchers were included in the preseason analysis. The average age and playing experience were 20.1 years (standard deviation [SD], 1.3 years) and 15.3 years (SD, 1.8 years), respectively, with 2.5 years (SD, 1.2 years) playing at collegiate level. The dominant shoulder showed decreased internal rotation and increased external rotation (ER) relative to the nondominant side (P < .001). The average glenohumeral internal rotation deficit and ERG were 11.3° (SD, 9.87°) and 5.71° (SD, 8.8°), respectively. ERG ≥ 5° was a significant predictor of elbow stress during pitching (47.4 Nm [SD, 0.7 Nm] vs. 45.1 Nm [SD, 0.6 Nm], P = .014). Univariate associations showed that each additional degree of ER resulted in increased elbow torque (ß estimate, 0.35 ± 0.06 Nm; P = .003). Conversely, decreased medial elbow torque was found in pitchers with reduced shoulder ROM (glenohumeral internal rotation deficit ≥ 20°: 43.5 Nm [SD, 1.1 Nm] vs. 46.6 Nm [SD, 0.5 Nm], P = .011; loss of total rotational ROM ≥ 5°: 43.6 Nm [SD, 1.1 Nm] vs. 46.6 Nm [SD, 0.5 Nm], P = .013) and in those with greater arm length (P < .05). CONCLUSIONS: College pitchers with increased ER produce greater medial elbow torque during the pitching movement. Each degree of increased ER was found to correlate with increased elbow torque and ball velocity. On the contrary, arm length and reduced shoulder ROM were associated with reduced medial elbow torque. This study suggests that increased ER in pitchers is associated with greater elbow stress during pitching.

Editorial Commentary: Making the Leap to the Patient-Reported Outcomes Measurement Information System: A Paradigm Shift That Will Ultimately Benefit Our Patients.

Numerous studies have demonstrated favorable psychometric and administrative characteristics of the National Institutes of Health Patient-Reported Outcomes Measurement Information System Computer Adaptive Test measures in orthopaedic patient populations. These dynamic assessments require significantly fewer questions than do traditional patient-reported outcome measures, thus requiring less time for survey completion. Their domain-specific nature and standardized scoring make them uniquely suitable for population health assessments. Although some challenges exist in improving adoption of Patient-Reported Outcomes Measurement Information System Computer Adaptive Test forms across orthopaedics, there is growing momentum to increase use of these tools across clinical and research orthopaedic applications.

What Are the Floor and Ceiling Effects of Patient-Reported Outcomes Measurement Information System Computer Adaptive Test Domains in Orthopaedic Patients? A Systematic Review.

PURPOSE: To perform a systematic review to answer the following: (1) What are the floor and ceiling (F/C) effects of the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive test (CAT) domains of physical function (PF), upper extremity physical function (UE), pain interference (PI), and depression (D) in adult orthopaedic patients? (2) Do the PROMIS-PF and PROMIS-PI domains have differing F/C effects depending on use in upper extremity, lower extremity, spine, neck, and back, or trauma patients?. METHODS: (Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines were followed, the review was registered on PROSPERO, and the methodological index for non-randomized studies was used for this systematic review. Studies reporting the F/C effects of at least 1 of 4 PROMIS CAT domains in orthopaedic patient cohorts accessed through PubMed and Embase on October 30, 2018, were included. F/C effects for each study were reported within forest plots. RESULTS: Forty-three studies were included. Generally, varying cohorts demonstrated no F/C effects for PROMIS-PF (0%-9.0%), variable ceiling effects for PROMIS-UE (lower in v2.0; 0%-28.2%), variable floor effects for PROMIS-PI (0%-19.0%), and significant floor effects for PROMIS-D (0.4%-23.4%). CONCLUSIONS: The orthopaedic literature demonstrated generally favorable floor and ceiling effects for PROMIS CAT domains, with the exception of variable ceiling effects for PROMIS-UE (the newer version exhibits only minor effects), variable floor effects for PROMIS-PI, and significant floor effects for PROMIS-D. In addition, the F/C effects of PROMIS-PF did not vary based on patient population. Although the floor effects of PROMIS-PI did vary based on patient population, the variability does not appear to be based solely on anatomic location. The PROMIS-PF and PROMIS-UE v2.0 demonstrate consistently low floor and ceiling effects. However, the PROMIS-PI and PROMIS-D may need modification before widespread adoption for clinical and research purposes. LEVEL OF EVIDENCE: III; systematic review of Level I-III studies.
