Understanding postoperative rehabilitation preferences in operatively managed proximal humerus fractures: do trauma and shoulder surgeons differ?

BACKGROUND: Proximal humerus fractures (PHFs) are common, and their incidence is increasing as the population ages. Despite this, postoperative rehabilitation remains unstandardized and little is known about surgeon preferences. The aim of this study was to assess differences in postoperative rehabilitation preferences and patient education between orthopedic trauma and shoulder surgeons. METHODS: An electronic survey was distributed to members of the Orthopaedic Trauma Association and the American Shoulder and Elbow Surgeons to assess differences in postoperative rehabilitation preferences and patient counseling. Descriptive statistics were reported for all respondents, trauma surgeons, and shoulder surgeons. Chi-square and unpaired 2-sample t tests were used to compare responses. Multinomial regression was used to further elucidate the influence of fellowship training independent of confounding characteristics. RESULTS: A total of 293 surgeons completed the survey, including 172 shoulder and 78 trauma surgeons. A greater proportion of trauma surgeons preferred an immediate weightbearing status after arthroplasty compared to shoulder surgeons (45% vs. 19%, P = .003), but not after open reduction and internal fixation (ORIF) (62% vs. 75%, P = .412). A greater proportion of shoulder surgeons preferred home exercise therapy taught by the physician or using a handout following reverse shoulder arthroplasty (RSA) (21% vs. 2%, P = .009). A greater proportion of trauma surgeons began passive range of motion (ROM) <2 weeks after 2-part fractures (70% vs. 41%, P < .001). Conversely, a greater proportion of shoulder surgeons began passive ROM between 2 and 6 weeks for 2-part (57% vs. 24%, P < .001) and 4-part fractures (65% vs. 43%, P = .020). On multinomial regression analysis, fellowship training in shoulder surgery was associated with preference for a nonweightbearing duration of >12 weeks vs. 6-12 weeks after ORIF. Similarly, fellowship training in shoulder surgery was associated with increased odds of preferring a nonweightbearing duration of <6 weeks vs. no restrictions and >12 weeks vs. 6-12 weeks after arthroplasty. Training in shoulder surgery was associated with greater odds of preferring a nonweightbearing duration prior to beginning passive ROM of 2-6 weeks vs. <2 weeks or >6 weeks for 2-part fractures, but not 4-part fractures. CONCLUSION: Trauma surgeons have a more aggressive approach to rehabilitation following operative PHF repair compared to shoulder surgeons regarding time to weightbearing status and passive ROM. Given the increasing incidence of PHFs and substantial variations in reported treatment outcomes, differences in rehabilitation after PHF treatment should be further evaluated to determine the role it may play in the outcomes of treatment studies.

A validated algorithm using current literature to judge the appropriateness of anatomic total shoulder arthroplasty utilizing the RAND/UCLA appropriateness method.

BACKGROUND: Currently, appropriateness criteria evaluating when to perform total shoulder arthroplasty (TSA) is lacking. In the absence of society guidelines and limited quality evidence, the RAND/University California in Los Angeles (UCLA) method provides a suitable alternative to evaluate appropriateness and assist in clinical decision making. Given the rise in utilization, appropriateness criteria for TSA have the potential to be an extremely powerful tool for improving quality of care and controlling costs. Thus, the goal of this study was to test explicit criteria to assess the appropriateness of TSA decision making using the RAND/UCLA appropriateness method. METHODS: A review of recent scientific literature to gather available evidence about the use, effectiveness, efficiency, and the risks involved in surgical intervention was performed by a shoulder/elbow fellowship trained physician. Based on pertinent variables including age, rotator cuff status, previous surgical management, mobility, symptomatology, and imaging classifications, 186 clinical scenarios were created. Appropriateness criteria for TSA were developed using a modified Delphi method with a panel consisting of American Shoulder and Elbow Surgeons (ASES) members. A second panel of ASES members rated the same scenarios, with reliability testing performed to compare groups. RESULTS: Panel members reached agreement in 40 (64%) indications. TSA was appropriate in 15 (24%) of indications. For patients with severe symptomatology, TSA was often appropriate for patients aged <75 years and inconclusive or inappropriate for patients aged >75 years. Among patients aged <65 years, TSA varied between appropriate and inconclusive, often dependent on Walch classification. For patients with moderate symptomatology, TSA was inappropriate or inconclusive for patients aged <65 or >75 years. When compared to the second panel's results, moderate agreement was obtained with a weighted kappa statistic of 0.56. CONCLUSIONS: Using the RAND/UCLA method, ASES members created an appropriateness decision tree for pertinent patient variables. This presents the data in a manner that streamlines the clinical decision-making process and allows for rapid and more reliable determination of appropriateness for practitioners. The decision tree is based on a combination of clinical experience from high-volume ASES-member surgeons and a comprehensive review of current evidence. This tool can be used as part of a broader set of factors, including individual patient characteristics, prior studies, and expert opinion, to inform clinical decision making, improve quality of care, and control costs.

Rotator cuff repair in HIV-positive patients ages 65 and older: only slight increase in risk of general postoperative surgical complications.

PURPOSE: To examine postoperative complications associated with rotator cuff repair (RCR) in HIV-positive patients ages 65 and older. METHODS: Data were collected from the Medicare Standardized Analytic Files between 2005 and 2015 using the PearlDiver Patient Records Database. Subjects were selected using Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes. Demographics including age, sex, medical comorbidities, and smoking status were collected. Complications were examined at 7-day, 30-day, and 90-day postoperative time points. Data were examined with univariate and multivariate analyses. RESULTS: The study included 152,114 patients who underwent RCR, with 24,486 (16.1%) patients who were HIV-positive. Following univariate analysis, patients with HIV were observed to be more likely to develop 7-day, 30-day, and 90-day postoperative complications. However, the absolute risk of each complication was quite low for HIV-positive patients. Univariate and multivariate analysis showed that within 7 days following surgery, patients with HIV were more likely to develop myocardial infarction (OR 2.5, AR 0.1%) and sepsis (OR 2.5, AR 0.04%). Within 30 days, HIV-positive patients were at increased risk for postoperative anemia (OR 2.8, AR 0.1%), blood transfusion (OR 3.3, AR 0.1%), heart failure (OR 2.3, AR 0.8%), and sepsis (OR 2.7, AR 0.1%). Within 90 days, mechanical complications (OR 2.1, AR 0.1%) were increased in the HIV-positive group. CONCLUSION: Postoperative complications of RCR occurred at increased rates in the HIV-positive group compared to the HIV-negative group in patients ages 65 and older. In particular, increased risk for myocardial infarction, sepsis, heart failure, anemia, and mechanical complications was noted in HIV-positive patients. However, the actual percentage of patients who experienced each complication was low, indicating RCR is likely safe to perform even in older HIV-positive patients. As more older adults living with HIV present for elective orthopedic procedures, the results of the present study may reassure physicians who are considering RCR as an option for patients in this particular population, while also informing providers about potential complications.

Outcome measures reported for the management of proximal humeral fractures: a systematic review.

BACKGROUND: The American Shoulder and Elbow Surgeons multicenter taskforce studying proximal humerus fractures reached no consensus on which outcome measures to include in future studies, and currently no gold standard exists. Knowledge of commonly used outcome measures will allow standardization, enabling more consistent proximal humerus fracture treatment comparison. This study identifies the most commonly reported outcome measures for proximal humerus fracture management in recent literature. METHODS: A systematic review identified all English-language articles assessing proximal humerus fractures from 2008 to 2018 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Review articles, meta-analyses, revision surgery, chronic injuries, studies with <15 patients, studies with <12 month follow-up, anatomic/biomechanical studies, and technique articles were excluded. Included studies were assessed for patient demographics and outcome scores, patient satisfaction, complications, range of motion, and strength. RESULTS: Of 655 articles, 74 met inclusion criteria. The number of proximal humerus fractures averaged 74.2 per study (mean patient age, 65.6 years). Mean follow-up was 30.7 months. Neer type 1, 2, 3, and 4 fractures were included in 8%, 51%, 81%, and 88% of studies, respectively. Twenty-two patient-reported outcome instruments were used including the Constant-Murley score (65%), Disabilities of the Arm, Shoulder, and Hand score (31%), visual analog scale pain (27%), and American Shoulder and Elbow Surgeons score (18%). An average of 2.2 measures per study were reported. CONCLUSION: Considerable variability exists in the use of outcome measures across the proximal humerus fracture literature, making treatment comparison challenging. We recommend that future literature on proximal humerus fractures use at least 3 outcomes measures and 1 general health score until the optimal scores are determined.

Nonanatomic Tibial Tunnel Placement for Single-Bundle Posterior Cruciate Ligament Reconstruction Leads to Greater Posterior Tibial Translation in a Biomechanical Model.

PURPOSE: To determine the effect of varying proximal-distal tibial tunnel placement on posterior cruciate ligament (PCL) laxity. METHODS: Nine matched pairs (18 total) of cadaveric knees (mean age 79.3 years, range 60 to 89), were studied. The specimens from each pair were randomly divided into 2 groups based on tibial tunnel placement: (1) anatomic tunnel and (2) proximal nonanatomic tunnel. A 150-N cyclic posterior tibial load was applied using a Materials Testing System machine at 0°, 30°, 60°, and 90° of knee flexion. Each specimen completed 50 cycles at a rate of 0.2 Hz at each knee flexion angle. In 10 specimens, a static 250-N posterior tibial load was applied at 90° of knee flexion. Posterior tibial translation was recorded. Load to failure for all specimens was recorded. RESULTS: With application of a 150-N posteriorly directed cyclic force, the anatomic tunnel group had significantly less posterior tibial translation (millimeters, mean [standard deviation (SD)]) than the proximal nonanatomic tunnel group at 0°, 30°, 60°, and 90° of knee flexion: 1.1 (0.3) v 1.5 (0.4), P = .031; 1.1 (0.6) v 2.2 (0.9), P = .019; 0.9 (0.4) v 2.0 (0.6), P = .001; 0.9 (0.6) v 2.9 (0.7), P < .001, respectively. The anatomic tunnel group also demonstrated significantly less posterior tibial translation (millimeters, mean [SD]) than the nonanatomic tunnel group at 90° with a static 250-N posteriorly directed force applied (P <.05): 2.3 (1.3) v 6.1 (2.3), P = .016. Four pairs were excluded from the 250-N results because of prior load to failure testing. CONCLUSIONS: Anatomic tibial tunnel placement re-creating the tibial origin of the PCL results in significantly less posterior tibial translation than proximal nonanatomic tibial tunnel placement. Correct placement of the tibial tunnel during PCL reconstruction is essential for avoidance of posterior laxity. CLINICAL RELEVANCE: Anatomic tibial tunnel placement during PCL reconstruction may ensure a more stable reconstruction.

The role of magnetic resonance imaging in a Division I university sports medicine program.

OBJECTIVE: To prospectively document musculoskeletal magnetic resonance imaging (MRI) use and how it affects diagnosis, playing status, and treatment of Division I university athletes. We hypothesized that MRI often has little or no effect on the diagnosis or treatment plan. DESIGN: Cross-sectional study. SETTING: Division I university sports medicine program. PATIENTS: Division I university varsity athletes. INTERVENTIONS: Data were collected of musculoskeletal MRI use in varsity student athletes for 2 full academic years from 2010 to 2012 at a National Collegiate Athletic Association Division I institution. MAIN OUTCOME MEASURES: Timing of the injury, first physician visit, and MRI and pre- and post-MRI diagnosis, playing status, and treatment (surgical vs nonsurgical). RESULTS: Eighty-six MRIs were obtained during the 2 years studied. Average age was 19.9 (18-23) years. Forty-five percent of injuries occurred during competition season, 34% occurred preseason, and 21% occurred postseason. There was a change in diagnosis in 13 athletes (15.1%, 1 led to surgery performed after completion of the season), and there was a change in participation status in 8 athletes (9.3%, 5 increased and 3 decreased). Treatment plan changed in 1 athlete (1.2%). No athlete required surgery immediately after an MRI that was not already being planned. Every athlete treated nonsurgically pre-MRI was able to finish their season. CONCLUSIONS: Magnetic resonance imaging was obtained in 14% of athletes and did not demonstrate a clear benefit over history, examination, and radiographs. Magnetic resonance imaging did change diagnosis in 15% of cases, though it did not appreciably change the playing status or treatment plan.

"Lost in Translation: The Readability Discrepancy of Online Patient Educational Materials for PCL Surgery".

Objectives: While the internet provides accessible medical information, often times it does not cater to the average patient's ability to understand medical text at a 6th and 8th grade reading level, per American Medical Association (AMA)/National Institute of Health (NIH) recommendations. This study looks to analyze current online materials relating to posterior cruciate ligament (PCL) surgery and their readability, understandability, and actionability. Methods: The top 100 Google searchs for "PCL surgery" were compiled. Research papers, procedural protocols, advertisements, and videos were excluded from the data collection. The readability was examined using 7 algorithms: the Flesch Reading Ease Score, Gunning Fog, Flesch-Kincaid Grade Level, Coleman-Liau Index, SMOG index, Automated Readability Index and the Linsear Write Formula. Two evaluators assessed Understandability and Actionability of the results with the Patient Educational Materials Assessment Tool (PEMAT). Outcome measures included Reading Grade Level, Reader's age minimum and maximum, Understandability, and Actionability. Results: Of the 100 results, 16 were excluded based on the exclusion criteria. There was a statistically significant difference between the readability of the results from all algorithms and the current recommendation by AMA and NIH. Subgroup analysis demonstrated that there was no difference in readability as it pertained to which page they appeared on Google search. There was also no difference in readability between individual websites versus organizational websites (hospital and non-hospital educational websites). Three articles were at the 8th grade recommended reading level, and all three were from healthcare institutes. Conclusion: There is a discrepancy in readability between the recommendation of AMA/NIH and online educational materials regarding PCL surgeries, regardless of where they appear on Google and across different forums. The understandability and actionability were equally poor. Future research can focus on the readability and validity of video and social media as they are becoming increasingly popular sources of medical information.

Biomechanical comparison of long head of biceps tenodesis with interference screw and biceps sling soft tissue techniques.

PURPOSE: The purpose of our study was to compare biomechanically a long head biceps tenodesis using an all soft tissue biceps sling technique versus an interference screw technique. METHODS: Six paired fresh frozen shoulder specimens were separated into 2 groups. One group used an all soft tissue biceps sling technique for tenodesis. The other group used the interference screw technique for subpectoral tenodesis of the long head biceps tendon. Specimens in both groups were sequentially loaded for 200 cycles, and the difference between the initial and final displacements were recorded. Specimens were then loaded to failure. Load and mode of failure were recorded. RESULTS: The mean displacement of all specimens undergoing the sling technique was significantly less than that of the interference technique at 3.0 mm (±0.80) versus 5.0 mm (±1.08) (P < .05). The biceps sling technique had a higher mean ultimate failure load (UFL) than did the interference screw tenodesis (216.9 N ± 91.6 v 171.7 N ± 101.4), although this was not statistically significant (P = .63). In the interference screw technique, 4 specimens failed at the tenodesis site by either tearing or complete pullout, whereas 2 failed at the biceps myotendinous junction. In the sling technique, 4 specimens failed at the biceps myotendinous junction, whereas one specimen tore at the tenodesis site and one detached the pectoralis tendon insertion from the humerus. One specimen in the biceps sling technique and 2 specimens in the interference screw technique failed before completing all 200 cycles. CONCLUSIONS: The results of this biomechanical study show that the biceps sling technique has construct stability similar to that of the interference screw technique. CLINICAL RELEVANCE: The biceps sling may be a reasonable alternative for treating symptomatic pathologic conditions of the long head biceps tendon.

Arthroscopic evaluation of knee lateral compartment widening after lateral ligamentous injury.

PURPOSE: To evaluate whether diagnostic arthroscopy of the lateral tibiofemoral compartment can determine the presence of a lateral ligamentous knee injury. METHODS: Nine cadaveric knee specimens were used with varus stresses of 12 Nm and the force at which no further lateral opening occurred. Arthroscopic measurements were taken of the lateral compartments with knees at 30°, 45° and 90°. Measurements were recorded in the intact knees and with sequential sectioning of LCL, popliteus, popliteofibular, ACL and PCL. Measurements and opening differences between each ligament state were recorded. RESULTS: No significant difference existed between the two forces compared (p < 0.05). There was a significant difference in opening distance measured at all knee angles with sequential sectioning (p < 0.001). Sequential opening difference between each ligament state was significantly different (p < 0.001) and also when compared across each knee angle (p < 0.001). At 30° for an isolated LCL injury, the average lateral opening was 10.1 mm. For a combined LCL and PLC (popliteus tendon and popliteofibular ligament) injury, the average lateral opening was 12.9 mm. For LCL-, PLC- and ACL-deficient knees, there was average lateral opening of 16.5 mm. CONCLUSIONS: LCL and combined lateral ligamentous injuries can be differentiated during arthroscopy with varus stress. This may be useful when deciding if there is a need for operative repair of any injured lateral ligamentous structures.

Time to return to school following ACL reconstruction: influence of the COVID-19 pandemic.

INTRODUCTION: ACL reconstruction is commonly performed in school-aged patients for whom missed time from school can have an impact on their education. Additionally, the COVID-19 pandemic has led to different ways of accessing school content. We sought to determine how many days of school school-aged patients should expect to miss following ACL reconstruction and how the availability of remote learning during the COVID-19 pandemic affected this. METHODS: We evaluated 53 ACL reconstruction patients in grades 7-12 undergoing surgery during the school year. Demographic, medical, and educational information were collected. Patients were placed into 1 of 2 cohorts: Group A (surgery before the COVID-19 pandemic) or Group B (surgery during the COVID-19 pandemic). We calculated days missed from school after surgery until return to either virtual or in-person school. RESULTS: Overall, patients returned to school after missing an average of 4.4 (SD, 3.0) days of school after ACL reconstruction surgery. Patients in Group A missed an average of 5.5 (SD, 2.9) school days, while patients in Group B missed an average of 2.3 (SD, 1.4) school days (p <.001). Eighty-nine percent of Group B patients first returned to school utilizing a virtual option. Among those returning virtually, these patients missed an average of 1.9 (SD, 0.9) school days. CONCLUSIONS: A virtual distance learning option results in fewer missed days of school post ACL reconstruction. When given this option, school-aged patients can expect to return to school within two days post-op. Otherwise, patients should expect to miss about one week of in-person schooling. In this regard, the COVID-19 pandemic has positively impacted educational opportunities for students post-surgery, and physicians should advocate for continuing virtual options for students receiving medical treatment.

An Anatomically Placed Tibial Tunnel does not Completely Surround a Simulated PCL Reconstruction Graft in the Proximal Tibia.

INTRODUCTION: It is hypothesized that anatomic tunnel placement will create tunnels with violation of the posterior cortex and subsequently an oblique aperture that is not circumferentially surrounded by bone. In this article, we aimed to characterize posterior cruciate ligament (PCL) tibial tunnel using a three-dimensional (3D) computed tomography (CT) model. METHODS: Ten normal knee CTs with the patella, femur, and fibula removed were used. Simulated 11 mm PCL tibial tunnels were created at 55, 50, 45, and 40 degrees. The morphology of the posterior proximal tibial exit was examined with 3D modeling software. The length of tunnel not circumferentially covered (cortex violation) was measured to where the tibial tunnel became circumferential. The surface area and volume of the cylinder both in contact with the tibial bone and that not in contact with the tibia were determined. The percentages of the stick-out length surface area and volume not in contact with bone were calculated. RESULTS: The mean stick-out length of uncovered graft at 55, 50, 45, and 40 degrees were 26.3, 20.5, 17.3, and 12.7 mm, respectively. The mean volume of exposed graft at 55, 50, 45, and 40 degrees were 840.8, 596.2, 425.6, and 302.9 mm3, respectively. The mean percent of volume of exposed graft at 55, 50, 45, and 40 degrees were 32, 29, 25, and 24%, respectively. The mean surface of exposed graft at 55, 50, 45, and 40 degrees were 372.2, 280.4, 208.8, and 153.3 mm2, respectively. The mean percent of surface area of exposed graft at 55, 50, 45, and 40 degrees were 40, 39, 34, and 34%, respectively. CONCLUSION: Anatomic tibial tunnel creation using standard transtibial PCL reconstruction techniques consistently risks posterior tibial cortex violation and creation of an oblique aperture posteriorly. This risk is decreased with decreasing the angle of the tibial tunnel, though the posterior cortex is still compromised with angles as low as 40 degrees. With posterior cortex violation, a surgeon should be aware that a graft within the tunnel or socket posteriorly may not be fully in contact with bone. This is especially relevant with inlay and socket techniques.

Does the addition of post-operative gabapentin reduce the use of narcotics after orthopedic surgery?

OBJECTIVES: To evaluate the efficacy of post-operative gabapentin administration as an analgesic agent and its effect on narcotic use after orthopedic surgery in an outpatient sports medicine practice by comparing patients prior to and after initiating the routine use of gabapentin as part of a standardized post-operative pain medication regimen. We hypothesized that adding gabapentin to a multimodal post-operative pain regimen would decrease the number of requested pain medication refills and have no detrimental effect on Visual Analogue Scale and Single Assessment Numerical Evaluation scores at these early post-operative visits. METHODS: All outpatient surgical patients, <90 years of age, undergoing outpatient orthopedic surgery by the study's senior author were included between 08/05/2021 and 02/22/2022. Patients were allowed 1 narcotic refill post-operatively and only in the first 3 weeks. The primary outcome was difference in percentage of patients who requested a narcotic refill within 3 weeks post-op. Two- and 6-week Visual Analogue Scale and Single Assessment Numerical Evaluation scores, and baseline health and demographic data. T-tests were run on continuous variables, Chi-Square or Fisher's Exact Test were run on dichotomous variables, and Mann-Whitney U test was run on all other categorical variables. Statistical significance was set at P < .05 for all tests. RESULTS: There was a significant difference in narcotic refills at 3 weeks: 23 pre-gabapentin patients and 9 post-gabapentin patients (22.8% vs 9.0%, respectively: P = .006). There were no differences between 2- and 6-week Visual Analogue Scale and 2-week Single Assessment Numerical Evaluation scores. There was a significant difference in 6-week SANE between groups: mean difference = 6.4 (P = .027) though less than the established MCID. CONCLUSION: Addition of gabapentin to a post-operative multimodal pain regimen reduced the use of narcotics after orthopedic sports medicine surgeries while also providing equivalent pain control.

Anticoagulant Usage After Anterior Cruciate Ligament Reconstruction Is Associated With Increased Rate of Manipulation Under Anesthesia.

BACKGROUND: Arthrofibrosis after anterior cruciate ligament reconstruction (ACLR) is a notable but uncommon complication of ACLR. To improve range of motion after ACLR, aggressive physical therapy, arthroscopic/open lysis of adhesions, and revision surgery are currently used. Manipulation under anesthesia (MUA) is also a reasonable choice for an appropriate subset of patients with inadequate range of motion after ACLR. Recently, the correlation between anticoagulant usage and arthrofibrosis after total knee arthroplasty has become an area of interest. The purpose of this study was to determine whether anticoagulant use has a similar effect on the incidence of MUA after ACLR. METHODS: The Mariner data set of the PearlDiver database was used to conduct this retrospective cohort study. Patients with an isolated ACLR were identified by using Current Procedural Terminology codes. Patients were then stratified by MUA within 2 years of ACLR, and the use of postoperative anticoagulation was identified. In addition, patient demographics, medical comorbidities, and timing of ACLR were recorded. Univariate and multivariable analyses were used to model independent risk factors for MUA. RESULTS: We identified 216,147 patients who underwent isolated ACLR. Of these patients, 3,494 (1.62%) underwent MUA within 2 years. Patients who were on anticoagulants after ACLR were more likely to require an MUA (odds ratio [OR]: 2.181; P < 0.001), specifically low-molecular-weight heparin (OR: 2.651; P < 0.001), warfarin (OR: 1.529; P < 0.001), and direct factor Xa inhibitors (OR: 1.957; P < 0.001). DISCUSSION: In conclusion, arthrofibrosis after ACLR is associated with the use of preoperative or postoperative thromboprophylaxis. Healthcare providers should be aware of increased stiffness among these patients and treat them aggressively.

Lack of race/ethnic minority representation in ulnar collateral ligament reconstruction in baseball athletes: a systematic review.

OBJECTIVES: To assess the reporting and representation of ethnic and racial minorities in comparative studies of ulnar collateral ligament (UCL) injuries and treatment in baseball athletes. METHODS: A systematic review of the literature was conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The literature search was conducted by two independent reviewers using the PubMed, Scopus, and Cochrane Library databases. Studies were included if they were UCL of the elbow clinical comparative studies, including randomized clinical trials, cohort studies, case series, and epidemiological studies. Studies were excluded if they were related to ulnar collateral ligament of the thumb, lateral ulnar collateral ligament of the elbow, biomechanical studies, non-surgical studies, non-baseball studies, and systematic reviews and meta-analyses. The Methodological Index for Non-Randomized Studies (MINORS) criterion was used to assess quality of studies included. RESULTS: A total of 108 studies were included for analysis, of which only one reported race and ethnicity in their demographics. Additionally, of the 108 studies included, only four reported Country of Origin, a subset of Race and Ethnicity, in their demographics. CONCLUSION: Race and Ethnicity demographics are scarcely reported in comparative studies evaluating ulnar collateral ligament reconstruction. Future studies evaluating similar populations should strongly consider reporting racial and ethnic demographics as this may provide clarity on any potential effect these might have on post-surgical outcomes, particularly in high-level pitchers.

What effect does anterior cruciate ligament tibial guide orientation have on tibial tunnel length?

PURPOSE: To evaluate the effects of alteration in tibial guide pin insertion angle and external starting point on tibial tunnel length for anterior cruciate ligament (ACL) reconstruction. METHODS: Ten cadaveric tibial specimens were used. One pin was placed at each of variable insertion angles (55°, 50°, and 45°) of the tibial targeting device aimed at the center of the tibial ACL footprint. These 3 pins started externally along the anterior border of the superficial medial collateral ligament. A fourth pin at 50° was placed at a different external tibial starting point 1.5 cm anterior to the anterior border of the superficial medial collateral ligament. The intraosseous length of each pin was measured. Statistic analyses were performed with the Kruskal-Wallis test, with significance set at P < .05. RESULTS: The mean length for the 55° tibial tunnel was 50.3 mm (range, 42 to 56 mm); for the 50° tunnel, it was 48.9 mm (range, 44 to 55 mm); for the 50° anterior tunnel, it was 47.6 mm (range, 39 to 55 mm); and for the 45° tunnel, it was 47.3 mm (range, 41 to 52 mm). Changing the angle of the tibial guide did not significantly affect the length of the tibial tunnel (P = .18). Changing the external tibial starting point did not affect the length of the tibial tunnel (P = .39). CONCLUSIONS: Changing the tibial guide angle between 45°, 50°, and 55° does not appreciably change tibial tunnel length. Moving the starting point anterior 1.5 cm toward the tibial tubercle also has no effect on the tibial tunnel length. The lack of significant changes in tunnel length with these interventions may reflect the associated changes that occur in proximal tibial morphometry with change in external tibial starting position. CLINICAL RELEVANCE: Changing tibial tunnel length in ACL reconstruction likely requires more distalization of the external tibial starting point than is achieved simply by altering the tibial aiming guide angle by 10° or less.

Inter- and intraobserver reliability of the clock face representation as used to describe the femoral intercondylar notch.

PURPOSE: To validate the use of the clock face reference as a reliable means of communicating femoral intercondylar notch position. METHODS: A single red mark was made on ten identical left Sawbones femurs in the intercondylar notch at variable locations. Ten surgeons, who routinely perform ACL reconstructions, were presented the femurs in random order and asked to state the position of the mark to the nearest 30-min interval. Responses were recorded and then repeated 3 weeks later. The same 10 surgeons were presented with 30 actual arthroscopic photographs of the intercondylar notch, performed at 90° of knee flexion, with a probe pointing at various locations (10 knees; 3 photographs/knee) along the lateral aspect of the notch. The results were then analyzed with an ICC, Cronbach's alpha test, and descriptive statistics. RESULTS: For the Sawbones, the ICC was 0.996 while individual physician's Cronbach's alpha test ranged from 0.954 to 0.999, indicating a very high interobserver and intraobserver reliability. The mean range of responses among the 10 surgeons was 1.6 h, SD 0.6. For the photographs, the ICC was also high at 0.997. There was a mean range of 1.1 h, SD 0.4, among surgeons. CONCLUSIONS: The clock face method is commonly utilized for both placement of the femoral tunnel during ACL reconstruction as well as describing the location of the ACL femoral tunnel between communicating surgeons. Despite a high statistical interobserver correlation, there is significant range among different surgeons' responses. The present study questions the reliability of the clock face method for use between surgeons as a stand alone tool. Other methods also utilizing anatomic landmarks may be more accurate for describing intercondylar notch anatomy. LEVEL OF EVIDENCE: III.

Day case versus inpatient total shoulder arthroplasty: A systematic review and meta-analysis.

BACKGROUND: A number of papers have been published comparing the safety and efficacy of day case and inpatient anatomic or reverse total shoulder arthroplasty. However, no systematic review of the literature has been published to date. The aim of this review was to determine if day case total shoulder arthroplasty (length of stay <24 h) leads to similar outcomes as standard-stay inpatients (length of stay ≥24 h). METHODS: The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviewers were queried for publications utilizing keywords that were pertinent to total shoulder arthroplasty, day case, outpatient and inpatient, clinical or functional outcomes, and complications. In order to determine the quantitative impact of day case total shoulder arthroplasty on readmission and revision rate, a meta-analysis was performed on articles that observed 30- or 90-day readmission or revision. RESULTS: Eight articles were found to be suitable for inclusion in the present study which included 6103 day case total shoulder arthroplasty and 147,463 inpatient total shoulder arthroplasty. Following meta-analysis, there was no significant difference among patients who underwent day case total shoulder arthroplasty compared to inpatient total shoulder arthroplasty regarding revision rates (OR: 1.001; 95% CI: 0.721-1.389; p = 0.995) and 30-day readmission rates (OR: 0.940; 95% CI: 0.723-1.223; p = 0.646). In contrast, patients who underwent day case total shoulder arthroplasty were less likely to have a readmission within 90 days compared to their inpatient counterparts (OR: 0.839; 95% CI: 0.704-0.999; p = 0.049). Two out of eight studies reported comparable baseline clinical characteristics among groups, while five studies reported significant differences and one study did not provide information regarding clinical characteristics, such as medical comorbidities or American Society of Anaesthesiologists'(ASA) score. No significant difference among groups was found in all or almost all studies regarding mortality rates, and rates of cardiac complications, cerebrovascular events, thromboembolic events, pulmonary complications, cardiac complications, and nerve complications. Finally, results were rather conflicting regarding the correlation of day case total shoulder arthroplasty to the rate of surgical site infections. CONCLUSIONS: This study showed that day case total shoulder arthroplasty might lead to similar rates of mortality, complications, revisions, and readmissions compared to inpatient total shoulder arthroplasty when used in a selected population of younger, healthier, and more male patients. In contrast, there was no consensus regarding the impact of day case total shoulder arthroplasty on the rate of surgical site infections. Finally, further research of higher quality is required to establish patient demographic criteria, ASA score, or comorbidity index cut off that might be used to define day case-treated patients who seem to have equivalent outcomes compared to inpatient-treated patients.Level of evidence: Systematic review of level III studies (lowest level included).

Effect of Patient Resilience and the Single Assessment Numeric Evaluation (SANE) Score on Return to Sport Following Anterior Cruciate Ligament Reconstruction Surgery.

BACKGROUND: This study aims to determine the effect of resilience, as measured by the Brief Resilience Scale (BRS), and perceived self-efficacy of knee function, as measured by the Single Assessment Numeric Evaluation (SANE) score on return to sport outcomes following ACL Reconstruction (ACLR) surgery. METHODS: Seventy-one patients undergoing ACLR surgery were followed up for a minimum of one year. At six-months post-op, ACLR patients completed the BRS and the SANE score. Patients were stratified into low, normal, and high resilience groups, and outcome scores were calculated. RESULTS: The median return to sports participation, in months post-operatively, for the low, normal, and high resiliency groups were 7.1, 7.3, and 7.2 months, respectively (P=0.78). A multiple logistic regression analysis revealed that the SANE score was a significant predictor of return to sport at nine months when adjusted for age, sex, and BRS score (P=0.01). Patients that returned to sport by nine months demonstrated a mean SANE score of 92.7, compared to a mean of 85.7 (P=0.08). In patients who had returned to sport, neither the BRS resilience group nor the SANE score were significant predictors of the returned level of competition status (P=0.06; P=0.18). CONCLUSION: The SANE score may serve as a significant predictor of return to sport when adjusted for age, sex, and BRS score. Resilience, as measured by the BRS, was not significantly associated with return to sport, but may have utility in specific patient populations.

A Prospective Assessment of Opioid Utilization Post-Operatively in Orthopaedic Sports Medicine Surgeries.

BACKGROUND: The healthcare system is plagued finding the balance between opioid use and abuse. Orthopaedic surgeons are expected to curtail the number of opioids prescribed in order to lower opioid abuse. We sought to prospectively evaluate opioid consumption following a wide range of sports orthopaedic surgical procedures to determine utilization patterns. METHODS: All patients receiving procedures within a one-year period were consented and then called daily for one week followed by weekly for up to two months or until the patients no longer were taking their opioid medication. We studied the number of opioids patient's took postoperatively and also collected information in regards to the patient and the surgical procedure. RESULTS: Included were 223 patients with a mean age of 32.9 years (range, 11 to 82). Surgeons prescribed a mean total of 59.5 pills, and patients reported consuming a mean total of 20.9 pills, resulting in a utilization rate of 40%. 94.4% of patients received no education on how to properly dispose of unused opioids. The mean SANE score was 53.9. The mean Pain Catastrophizing Scale score was 15.1. The mean Opioid Risk Tool was 3.3. The procedures were broken down into: 47.5% ligamentous knee repair, 18.4% shoulder arthroscopy/other shoulder, 7.6% meniscus, 7.6% shoulder arthroplasty, 5.4% distal biceps, 4.0% lower leg (ankle/foot/tibia) and 4.0% shoulder ORIF. CONCLUSION: Over-prescribing opioids after sports orthopaedic surgeries is widespread. In this study, we found that patients are being prescribed 2.48 times greater opioid medications than needed following sports orthopaedic surgical procedures. We recommend surgeons take care when prescribing postoperative pain control and consider customizing their opioid prescriptions on the basis of prior opioid usage, anatomic location and procedure type. We also recommend educating the patients on proper disposal of excess opioids and consider involving pain management for patients likely to require prolonged opioid usage.
