Arthroscopic subacromial decompression improved outcomes in situationally depressed patients compared to clinically depressed or nondepressed patients.

Background: The purpose of this study is to evaluate patient reported outcomes after arthroscopic extensive débridement of the shoulder with subacromial decompression (SAD) for subacromial impingement using the Patient-Reported Outcomes Measurement Information System (PROMIS) system and evaluate if depression (Dep) (clinical or situational) impacts patients achieving a Minimal Clinically Important Difference (MCID). Methods: Preoperative PROMIS Physical function (PF), Mood, and Dep scores were obtained at the closest date prior to arthroscopic rotator cuff repair and postoperative scores were collected at every clinical visit thereafter. Final PROMIS score used for data analysis was determined by the patients final PROMIS value between 90 to 180 days. Clinical Dep was determined by patients having a formal diagnosis of "Depression or Major Depressive Disorder" at the time of their surgery. Situationally depressed patients, those without a formal diagnosis yet exhibited symptomatic depressive symptoms, were classified by having a PROMIS-Dep cutoff scores larger than 52.5. Results: A total of 136 patients were included for final statistical analysis. 13 patients had a clinical but not situational diagnosis of Dep, 86 patients were identified who had no instance of clinical or situational Dep (nondepressed). 35 patients were situationally depressed. All three cohorts demonstrated a significant improvement in postoperative PROMIS Dep, PI, and PF score relative to their preoperative value (P = .001). Situationally depressed patients achieved greater delta PROMIS-Dep compared to patients with major depressive disorder. Depressed patients had a higher chance of achieving MCID for PROMIS-Dep compared to nondepressed patients (P = .01). Logistic regression analysis demonstrated that underlying Dep did not alter the odds of obtaining MCID compared to nondepressed patients. Nonsmoking patients had significantly greater odds of achieving MCID for PF (P = .02). Discussion: Patients improved after undergoing SAD regardless of underlying Dep or depressive symptoms. Depressed patients exhibited greater change in PROMIS scores compared to nondepressed patients. Smoking remains a risk factor for postoperative outcomes in patients undergoing SAD for subacromial impingement. Identifying and counseling patients with underlying depressive symptoms without a formal major depressive disorder diagnosis may lead to improved outcomes. These findings may help guide clinicians in deciding who would benefit the most from this procedure.

Use of Area Deprivation Index to Predict Minimal Clinically Important Difference for Patient Reported Outcomes Measurement Information System After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Socioeconomic disparities correlate with worse outcomes after arthroscopic rotator cuff repair. However, use of a surrogate to describe socioeconomic disadvantage has been a challenge. The Area Deprivation Index (ADI) is a tool that encompasses 17 socioeconomic variables into a single metric based on census location. HYPOTHESIS: Higher ADI would result in a worse minimal clinically important difference (MCID) for the Patient Reported Outcomes Measurement Information System (PROMIS) and have less improvement in range of motion (ROM) following arthroscopic rotator cuff repair (ARCR). STUDY DESIGN: Cohort study; Level of evidence, 3. METHOD: A retrospective review was performed for patients who underwent arthroscopic rotator cuff repair. Patients in the most socioeconomically disadvantaged quartile (ADIHigh) were compared with the least disadvantaged quartile (ADILow) in the ability to reach MCID. Demographic and surgical features were assessed for attainment of MCID. RESULTS: In total 1382 patients were identified who underwent ARCR, of which a total of 306 patients met final inclusion criteria. A higher percentage of patients within the ADIHigh cohort identified as "Black" or "other" race and had government-issued insurance compared with the ADILow cohort (P < .05). The ADIHigh cohort had significantly worse postoperative forward flexion compared with the ADILow cohort (145.0°± 32.5° vs 156.3°± 23.4°; P = .001) despite starting with comparable preoperative ROM (P = .17). Logistic regression showed that ADI was the only variable significant for predicting achievement of MCID for all 3 PROMIS domains, with the ADIHigh cohort having significantly worse odds of achieving MCID Physical Function (odds ratio [OR], 0.31; P = .001), Pain Interference (OR, 0.21; P = .001), and Depression (OR, 0.28; P = .001). Meanwhile, age, sex, body mass index, and smoking history were nonsignificant. Moreover, "other" for race and Medicare insurance were significant for achievement of MCID Depression but not Physical Function or Pain Interference. Finally, ADI was the main feature for predictive logistic regression modeling. CONCLUSION: ADI served as the only significant predictor for achieving MCID for all 3 PROMIS domains after arthroscopic rotator cuff repair. Patients who face high levels of socioeconomic disadvantage have lower rates of achieving MCID. In addition, patients with greater neighborhood disadvantage demonstrated significantly worse improvement in active forward flexion. Further investigation is required to understand the role of ADI on physical therapy compliance and to identify the barriers that prevent equitable postoperative care.

Effect of Insurance Reimbursement Status on Pre- and Postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Scores After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Previous studies reported inferior patient-reported outcomes (PROs) after arthroscopic rotator cuff repair for patients receiving workers' compensation (WC) relative to patients with commercial insurance. The extent to which alternative insurance reimbursement, including Medicaid and Medicare, influences outcomes after arthroscopic rotator cuff repair remains understudied. HYPOTHESIS: Compared with patients with commercial insurance reimbursement, patients with WC or government-issued reimbursement would report lower pre- and postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) scores, report higher pre- and postoperative PROMIS Depression (D) and Pain Interference (PI) scores, and experience smaller levels of improvement in all PROMIS domains with surgical intervention. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Demographic and surgical data were extracted from the medical record, and PROMIS domains were prospectively collected. Patients were divided into cohorts based on insurance reimbursement status. Differences between insurance-based cohorts for baseline variables, pre- and postoperative PROMIS scores, and change from baseline to final follow-up (delta) for PROMIS scores were evaluated using Kruskal-Wallis or chi-square tests. Mixed-effects linear regression models were performed to assess the influence of insurance while controlling for other variables. Survival analysis was performed to determine time to achieve minimal clinically important difference (MCID) for each PROMIS domain per cohort. RESULTS: 1252 patients underwent arthroscopic rotator cuff repair, met inclusion criteria, and completed PROMIS questionnaires. Statistically significant differences were noted in demographic variables including age (P < .001), sex (P < .001), ethnicity (P < .001), and body mass index (P < .001) between insurance-based cohorts. Unadjusted analysis revealed significantly higher PF scores and lower PI and D scores for the group with commercial insurance relative to those with Medicare, Medicaid, and WC at 6- and 12-month follow-up (P < .01 all comparisons), except for the Medicare versus commercial subcohort analysis for PI at 6 months (P = .28). These differences persisted for the Medicare, Medicaid, and WC groups (P < .03 all comparisons) after adjustment for confounding variables in linear regression. CONCLUSIONS: The baseline characteristics of patients undergoing arthroscopic rotator cuff repair differed based on insurance reimbursement. Patients with commercial insurance reported improved physical function, decreased pain interference, and improved mood (less depression) relative to patients with government-issued and WC insurance, with maximum improvement 6 to 12 months postoperatively. There were few significant differences between insurance groups in change of PROMIS scores from preoperative to postoperative intervals, indicating that differences in the baseline demographic and surgical characteristics of these groups accounted for differences in response to surgery.

Editorial Commentary: Social Determinants of Health Influence the Success of Shoulder Rotator Cuff Repair Outcomes: When You Do Everything Right, Yet Things Still Go Wrong.

Our ability to perform a technically sound surgery is not sufficient to ensure patients have an excellent clinical outcome. Social determinants of health disparities (SDHDs) profoundly impact health equality. Health disparities that exist in the United States are risk factors for inferior patient-reported outcomes and result in greater complication rates following rotator cuff repair surgery. The presence of SDHDs was associated with an increased risk of revision, stiffness, emergency department visits, medical complications, and costs. Economic and educational SDHDs were associated with the greatest risk of 1-year revision surgery. Improved understanding of these social variables can help with risk identification preoperatively. Surgeons may employ additional, holistic, bio-psycho-social, perioperative resources to provide high-quality, value-based care to at-risk patients who might be marginalized by our health care system.

An Innovative Seven-year Physician Scientist Residency Training Program That Addresses the Shortage of Academic Surgeons.

Due to the declining number of scientifically trained physicians and increasing demand for high-quality literature, our institution pioneered a seven-year Physician Scientist Training Program (PSTP) to provide research-oriented residents the knowledge and skills for a successful academic career. The present study sought to identify orthopaedic surgeons with MD/PhD degrees, residency programs with dedicated research tracks, and to assess the effectiveness of the novel seven-year program in training prospective academic orthopaedic surgeons. Surgeons with MD/PhD degrees account for 2.3% of all 3,408 orthopaedic faculty positions in U.S. residency programs. During the last 23 years, our PSTP residents produced 752 peer-reviewed publications and received $349,354 from 23 resident-authored extramural grants. Eleven of our seven-year alumni practice orthopaedic surgery in an academic setting. The seven-year PSTP successfully develops clinically trained surgeon scientists with refined skills in basic science and clinical experimental design, grant proposals, scientific presentations, and manuscript preparation.

Clinically Depressed Patients Having Anterior Cruciate Ligament Reconstruction Show Improved but Inferior Rate of Achieving Minimum Clinically Important Difference for Patient-Reported Outcomes Measurement Information System Compared With Situationally Depressed or Nondepressed Patients.

PURPOSE: To determine whether the preoperative diagnosis of depression predicted worse postoperative outcomes, including physical therapy (PT) compliance, return-to-sport, and patient-reported outcomes using the Patient-Reported Outcomes Measurement Information System (PROMIS) after anterior cruciate ligament (ACL) reconstruction. METHODS: A multisurgeon series of consecutive patients who had undergone ACL reconstruction with minimum 2-year follow-up were included. Chart review was conducted to determine depression diagnosis status, demographic data, rehabilitation PT compliance, return to sports, and patient-reported outcome data using PROMIS. Patients who met the PROMIS threshold for mild depression but did not carry a clinical diagnosis of depression were classified as "situationally depressed." RESULTS: Ninety-five of 115 consecutive patients (81%) met inclusion criteria with an average follow-up of 34 ± 1.9 months. Fourteen patients (15%) had a preoperative diagnosis of depression, whereas 21 (22%) were considered situationally depressed. Clinically depressed patients had a greater rate of PT noncompliance (33.2% ± 17.6% vs 21.9% ± 12.6%; P = .02) and a lower postoperative PROMIS Physical Function (50.8 ± 7.7 vs 57.8 ± 11.0; P = .03 compared with patients without depression. Situationally depressed patients had lower preoperative physical function (35.4 vs 42.5; P = .04) with no differences in postoperative outcomes scores compared to the non-depressed cohort.19/21 (90.5%) of situationally depressed patients had postoperative resolution of their depressive symptoms. CONCLUSIONS: Situationally depressed patients without a clinical diagnosis of depression can expect significant improvements in both pain and function, as well as a resolution of their depressed mood based on PROMIS scores as they progress through recovery after ACL reconstruction. Clinically depressed patients also experience significant improvements; however, their rate of achieving the minimum clinically important difference for PROMIS outcomes may be less than their nondepressed or situationally depressed counterparts. LEVEL OF EVIDENCE: III, prognostic comparative trial.

Academic Orthopaedics As a Driver of Gender Diversity in the Orthopaedic Workforce: A Review of 4,519 Orthopaedic Faculty Members.

BACKGROUND: The purpose of this study was to perform a cross-sectional analysis on the gender composition of practicing academic orthopaedic surgeons using three databases composed of clinical orthopaedic surgeons. METHODS: A comprehensive database of 4,519 clinically active academic orthopaedic surgeons was compiled for this study after the review of publicly available data. The complied data set was evaluated alongside orthopaedic databases obtained from the 2017 Association of American Medical Colleges (AAMC) Faculty Administrative Management Online User System and the 2016 American Academy of Orthopaedic Surgery (AAOS) Orthopaedic Practice in the US census representing the entire academy membership orthopaedic workforce. Gender status was obtained and compared between the three databases. RESULTS: Of the 4,519 clinically active academic orthopaedic surgeons analyzed, 435 (10%) were female compared with 19% for the AAMC faculty database and 7% for the AAOS members. Fourteen percent of women had achieved the rank of professor compared with 25% of the men (P < 0.001). AAMC faculty had a significantly higher percentages of female representation compared with both the clinical faculty (19% versus 10%; P < 0.001) and AAOS members (19% versus 7%; P < 0.001). CONCLUSION: Despite multiple initiatives designed to increase diversity, the 7% female representation in the orthopaedic workforce identified in this study remains markedly lower than other medical and surgical specialties. A higher percentage of women were associated with the AAMC orthopaedic faculty compared with clinically active female surgeons at these institutions. Academic orthopaedic surgeons had greater female representation than the general orthopaedic workforce, highlighting the importance of training institutions at promoting gender equity.

Implementation and Evaluation of a Formal Virtual Medical Student Away Rotation in Orthopaedic Surgery During the COVID-19 Pandemic: A Single Institution Pilot Experience.

Away rotations are a valuable experience for medical students when applying for residency. In light of the coronavirus disease 2019 pandemic, there has been significant interest in the development of virtually based substitutes. This study evaluates the utility of a formal virtual fourth-year medical student away rotation in orthopaedic surgery by surveying participants and provides recommendations for success. METHODS: A 2-week virtual orthopaedic elective was offered to fourth-year medical students in lieu of traditional in-person away rotations. The course consisted of multiple components such as subspecialty case-based didactics, "happy hours" with residents, assigned resident mentors, student case presentations, and observation of resident lectures. After course completion, anonymous surveys were administered to participants to evaluate the rotation. RESULTS: Twenty-three of 24 participating students (96%) completed the student survey, and 22 of 24 participating faculty and residents (82%) completed the resident/faculty survey. Most students were very (87%) or somewhat (9%) satisfied with their experience and found the rotation to be a very (35%) or somewhat useful (61%) substitute for an in-person rotation. Students indicated that the rotation very (91%) or somewhat positively (9%) influenced their perception of the program. All students indicated that the rotation was very educational. Most students (91%) reported that the rotation was very useful for learning about the program and culture, with subspecialty didactics and happy hours most useful. Faculty and residents indicated that the rotation was useful for getting to know the students (17% "very useful" and 83% "somewhat useful") and for assessing student characteristics, such as knowledge base and communication skills. CONCLUSIONS: A formal virtual orthopaedic surgery away rotation can be a valuable experience for medical students which provides educational value, insight into program culture, and an opportunity to demonstrate interest in the program. The curriculum and recommendations presented in this study can be used as a preliminary template for others interested in creating successful virtual rotations.

Clinical presentation, imaging findings, and arthroscopic features in skeletally immature and mature adolescent hip patients: a comparative double-cohort retrospective study.

The purpose of this study was to evaluate differences in clinical presentation and extent of surgery required based on skeletal maturity between two cohorts of adolescent hip arthroscopy patients. We hypothesized that skeletal immaturity would be associated with a lower frequency of pincer impingement and a decreased need for surgical acetabuloplasty. A database of 1481 hip arthroscopies performed by a single orthopaedic surgeon between 2008 and 2016 was queried. Patients ≤18 years of age with femoroacetabular impingement were divided into two groups based on Risser score: Risser 1-4 (skeletally immature) or Risser 5 (skeletally mature). Groups were compared with respect to presentation, diagnosis, and arthroscopic procedures performed. Eighty-eight skeletally immature and 49 skeletally mature patients were included. Mixed impingement was more common in skeletally mature patients than immature (67.3% vs. 48.9%, P = 0.037). Skeletal maturity was associated with a significantly increased probability of undergoing acetabuloplasty (odds ratio = 4.6, 95% confidence interval 1.4-15.5; P = 0.014). Extent of chondral degeneration was similar between groups. Our findings support the hypothesis that skeletally immature hips undergo acetabuloplasty less frequently and demonstrate similar chondromalacia compared with a skeletally mature cohort. These results suggest that arthroscopic treatment for impingement-associated hip pain may be a reasonable option to consider for symptomatic skeletally immature patients who have completed a structured course of nonoperative treatment. Additional longitudinal outcomes data are needed to clarify the natural history of impingement-associated hip pain in younger populations and whether hip arthroscopy delays progression of osteoarthritis in these patients.

Cemented versus uncemented fixation of second-generation Trabecular Metal glenoid components: minimum 5-year outcomes.

BACKGROUND: Total shoulder arthroplasty (TSA) with second-generation Trabecular Metal™ implants (Zimmer, Warsaw, IN, USA) has shown good short-term outcomes. Differences in outcomes between cemented and uncemented fixation are unknown. This study compared the clinical, radiographic, and patient-rated outcomes of TSA with cemented vs. uncemented TM glenoids at minimum 5-year follow-up. METHODS: Patients who underwent anatomic TSA with second-generation TM glenoid components for primary osteoarthritis were identified for minimum 5-year follow-up. The patients were divided into 2 groups: cemented and uncemented glenoid fixation. Outcome measures included implant survival, patient-rated outcome scores (Patient-Reported Outcomes Measurement Information System [PROMIS] and American Shoulder and Elbow Surgeons scores), shoulder range of motion, and radiographic analysis. Findings were compared between groups. RESULTS: The study included 55 shoulders: 27 in the cemented group (21 with full radiographic follow-up) and 28 in the uncemented group (22 with full radiographic follow-up). Both groups had similar follow-up times (6.6 years in cemented group vs. 6.7 years in uncemented group, P = .60). Moreover, the groups did not differ significantly in sex composition, age at the time of surgery, or preoperative Walch glenoid grade distribution. No patients required revision surgery. The 2 groups had similar preoperative range of motion, but patients in the uncemented group had greater follow-up forward flexion (P = .03), external rotation (P < .01), and lateral elevation (P = .03) than did patients in the cemented group. PROMIS scores were not significantly different between groups. American Shoulder and Elbow Surgeons scores were similar (89.8 in cemented group vs. 94.1 in uncemented group, P = .21). Mid-term radiographs showed a metal debris rate of 24% in the cemented group and 27% in the uncemented group. Although these values were not significantly different (P = .90), the frequency of mild metal debris (grade 1-2), when present, was greater in the uncemented group (grade 2 in 6 shoulders) than in the cemented group (grade 1 in 4 and grade 2 in 1, P = .02). There was a greater presence of mild (grade 1) radiolucent lines in the uncemented group (64%) than in the cemented group (29%, P < .01). No glenoid had evidence of loosening (defined by a change in position or radiolucent lines > 2 mm). The presence of metal debris and radiolucent lines did not have a significant effect on clinical outcomes. CONCLUSION: At minimum 5-year follow-up, TSA patients with TM glenoids demonstrated excellent clinical and patient-reported outcomes with a 100% implant survival rate, regardless of cemented vs. uncemented fixation. However, the uncemented group showed a significantly higher rate of radiolucent lines and a higher frequency of mild metal debris. These radiographic findings did not affect the clinical outcomes, and their implications for long-term outcomes and prosthesis survival is unknown.

Thrower's Exostosis of the Shoulder: A Systematic Review With a Novel Classification.

BACKGROUND: A variety of thrower's exostoses are grouped under the term Bennett lesion, which makes understanding diagnosis and treatment difficult. PURPOSE: To identify all types of reported thrower's and overhead athlete's exostoses and categorize them into a classification system to allow a morphology-based classification. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review of all articles pertaining to Bennett lesions and thrower's exostosis was performed. The classification and treatments were evaluated to describe the types, proposed causes, diagnosis, and treatment options. RESULTS: A total of 27 studies were included in the systematic review. The anatomic locations referenced in the study demonstrated posteroinferior, posterior, and posterosuperior glenoid lesions. Aggregate radiographic data demonstrated 158 of 306 patients (52%) with a thrower's exostosis of any type and location. Of these 158 patients with a radiographic lesion, 119 (75%) patients were symptomatic. The locations were posteroinferior in 110 patients (70%), directly posterior in 2 patients (1.3%), posterosuperior in 44 patients (28%), and unknown in 2 patients (1.3%). Avulsed lesions were present in 9 (5.7%) posteroinferior lesions, 0 direct posterior lesions, and 2 (1.3%) posterosuperior lesions. Treatment plans included both nonoperative and operative strategies, but operative intervention was more commonly reported for detached lesions. After operative intervention, only 61% of reported athletes returned to preinjury performance. CONCLUSION: Based on a comprehensive review of the literature, we identified several anatomic locations for a thrower's exostosis beyond the classic Bennett lesion. We categorized the reported exostoses into a new classification system for description of location and type (subperiosteal or free fragment) of the thrower's exostosis, which may be used to study future treatments. Current treatment strategies recommend that surgical treatment of thrower's exostosis is considered only after exhausting nonoperative management because reported return to sport is variable after surgery. The effectiveness of excision or repair for both subperiosteal and detached lesions has not been established.

Predictive Modeling to Determine Functional Outcomes After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Arthroscopic rotator cuff repair (ARCR) is one of the most commonly performed orthopaedic surgical procedures; however, patient-reported outcomes have varied greatly in the literature. PURPOSE: To identify preoperative factors that affect outcomes and to develop prognostic tools for predicting functional outcomes in future ARCR cases. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients were included who underwent ARCR for repairable full-thickness rotator cuff tears with at least 2 years of follow-up. Twelve predictors were entered as candidate predictors in each model: age, sex, workers' compensation (WC) status, previous cuff repair, tear size, tear shape, multiple-tendon involvement, tendon stump length, Goutallier classification, critical shoulder angle, length of follow-up, and baseline subjective outcomes score. Postoperative American Shoulder and Elbow Surgeons (ASES), 12-Item Short Form Health Survey Physical Component Summary (SF-12 PCS), QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand), and patient satisfaction were each modeled through proportional odds ordinal logistic regression. Model results were presented with marginal covariate effect plots and predictive nomograms. RESULTS: Overall, 552 shoulders fit inclusion criteria. The mean age at surgery was 60.2 years (range, 23-81 years). Twenty-five (4.5%) shoulders underwent revision cuff repair or reverse arthroplasty at a mean 1.9 years (range, 0.1-7.9 years) postoperatively. Overall, 509 shoulders were eligible for follow-up, and minimum 2-year postoperative patient-reported outcomes were obtained for 449 (88.2%) at a mean 4.8 years (range, 2-11 years). The ASES score demonstrated significant improvement from pre- to postoperative median (interquartile range): 58 (44.9-71.6) to 98.3 (89.9-100; P < .001). Women demonstrated significantly higher 2-year reoperation rates than men (5.8% vs 1.6%; odds ratio, 2.8 [95% CI, 0.73-9.6]; P = .023). Independently significant predictors for lower postoperative ASES scores included previous ARCR (P < .001), female sex (P < .001), and a WC claim (P < .001). Significant predictors for worse QuickDASH scores included WC claim (P < .001), female sex (P < .001), previous ARCR (P = .007), and ≥7 years of follow-up time. Significant predictors for lower SF-12 PCS scores included WC claim (P < .001), female sex (P = .001), and lower baseline SF-12 PCS. Last, significant independent predictors of patient satisfaction included previous ARCR (P = .004), WC claim (P = .011), female sex (P = .041), and age (P = .041). CONCLUSION: Excellent clinical outcomes and low failure rates were obtained after ARCR by using careful patient selection and modern surgical techniques for ARCR. Female sex, WC claim, and previous ARCR were significant predictors of poorer outcomes in at least 3 patient-reported outcome models. Prognostic nomograms were developed to aid in future patient selection, clinical decision making, and patient education.

Diversity among academic orthopedic shoulder and elbow surgery faculty in the United States.

BACKGROUND: The purpose of this study was to perform a cross-sectional analysis of diversity among academic shoulder and elbow surgeons in the United States. METHODS: US shoulder and elbow surgeons who participated in shoulder and elbow fellowship and/or orthopedic surgery resident education as of November 2018 were included. Demographic data (age, gender, race), practice setting, years in practice, academic rank, and leadership roles were collected through publicly available databases and professional profiles. Descriptive statistics were performed and findings were compared between different racial and gender groups. Statistical significance was set at P <.05. RESULTS: A total of 186 orthopedic shoulder and elbow surgeons were identified as participating in shoulder and elbow fellowship and/or orthopedic surgery residency education. Overall, 83.9% were white, 14.5% were Asian, 1.1% were Hispanic, 0.5% were an other race, and 0% were African American. In addition, 94.6% of surgeons were male, whereas 5.4% were female. Further, 64.5% of all surgeons had been in practice for >10 years, and 39.2% worked in an urban setting. Less than half (40.3%) of the surgeons practicing primarily at academic institutions held a professor rank. White surgeons had a significantly greater time in practice vs. nonwhite surgeons (mean 18.8 vs. 12.6 years, P < .01) and were more likely to hold a professor rank (44.0% vs. 21.7%, P = .04). CONCLUSION: Racial and gender diversity among US shoulder and elbow surgeons who participate in fellowship and residency education is lacking. Hispanic, African American, and female surgeons are underrepresented. Efforts should be made to identify the reasons for these deficiencies and address them to further advance the field of orthopedic shoulder and elbow surgery.

Lack of Additional Advanced Graduate Training by Orthopaedic Surgeons in Academic Practice: Current Employment and Recruitment Trends.

BACKGROUND: Orthopaedic surgery is ever changing and depends on diverse technical and intellectual skill sets. The purpose of the current study was to evaluate the percentage of academic orthopaedic surgeons with additional graduate degrees in the United States. METHODS: Data including advanced degree(s) (eg, PhD, MS, MBA, MPH, JD, and DVM), academic rank, leadership position, subspecialty, years since training completion, and sex were collected from websites for all academic orthopaedic surgery departments in the United States. Univariate analyses were performed to evaluate for differences in demographic data based on the advanced degree status. Data from the National Resident Matching Program (NRMP) were used to characterize graduate degree-holding US senior medical students who ranked orthopaedic surgery first relative to peers without additional advanced degrees and to applicants who ranked other specialties first. RESULTS: Of 4,519 faculty at 175 academic orthopaedic surgery departments in the United States, 7.1% held a graduate degree in addition to a medical doctorate. There was no difference in the percentage of faculty who held departmental leadership positions (P = 0.62) or who were full professors (P = 0.66) based on holding an additional graduate degree. Of 678 US senior applicants who ranked orthopaedic surgery first and successfully matched into the specialty in 2018, 12.5% held an additional graduate degree and 1.3% were MD-PhDs. Orthopaedic surgery had the second lowest percentage of matched medical students with additional advanced degrees, which was significantly lower than the top 10 specialties (range 16.1% to 21.6%; P < 0.05). Orthopaedic surgery recruited 1.6% of all MD-PhD applicants in 2018. DISCUSSION: Few academic orthopaedic surgery faculty and admitted orthopaedic residency candidates have additional graduate school training. The low percentage of orthopaedic faculty and trainees with additional advanced degrees relative to other specialties may represent a missed opportunity to recruit individuals with diverse skills to advance the field of orthopaedic surgery.

Diabetic hip arthropathy is associated with a higher prevalence of femoral head chondromalacia: a case-controlled study.

INTRODUCTION: No previous studies have characterised hip joint disease in diabetic patients undergoing hip arthroscopy. The purpose of our study was to evaluate intra-articular hip pathology and surgical variables in patients with diabetes compared to matched, non-diabetic controls. We hypothesised that diabetic patients would demonstrate a higher prevalence and severity of hip chondral pathology. METHODS: We retrospectively reviewed 795 consecutive hip arthroscopies performed by a single surgeon between 2010 and 2015. Patients ⩾18 years of age without a history of diabetes served as controls and were matched based on age, sex, body mass index, duration of symptoms, and operative side. Clinical symptoms, preoperative physical examination, and radiologic and intraoperative findings were assessed. The primary outcomes were the acetabular and femoral head chondromalacia index (CMI), calculated as the product of the Outerbridge chondromalacia grade and surface area (mm2*severity). RESULTS: 15 diabetic patients were matched to 137 non-diabetic controls. Diabetic patients demonstrated a higher prevalence of femoral head chondromalacia compared to controls both on magnetic resonance imaging (45.5% vs. 7.5%, p = 0.002) and during arthroscopy (100% vs. 75.9%, p = 0.042). Femoral head chondromalacia in diabetic patients had higher Outerbridge grade (2.4 vs. 2.0, p = 0.030) but similar CMI (513.0 vs. 416.4, p = 0.298) compared to controls. DISCUSSION: Femoral head chondral pathology was more prevalent and of higher severity grade in diabetic patients. The prevalence, size, and severity of acetabular chondral disease were similar between diabetic and non-diabetic patients. Multivariate analysis demonstrated that diabetic status was independently associated with the presence of femoral head chondromalacia.

The Influence of Naproxen on Biological Factors in Leukocyte-Rich Platelet-Rich Plasma: A Prospective Comparative Study.

PURPOSE: To quantify and compare normative catabolic and anabolic factor concentrations in leukocyte-rich platelet-rich plasma (LR-PRP) at various time points, including baseline, 1 week after initiating naproxen use, and after a 1-week washout period. METHODS: Asymptomatic healthy donors aged between 18 and 70 years were recruited (average age, 36.6 years; range, 25-64 years). Subjects were excluded from the study if they were actively taking any prescribed medications or nonsteroidal anti-inflammatory drugs (NSAIDs) or if they had any of the following at present or previously: blood or immunosuppression disorders, cancer, osteonecrosis, rheumatoid arthritis, avascular necrosis, NSAID intolerance, gastrointestinal or peptic ulcer disease, or kidney dysfunction. The anabolic factors vascular endothelial growth factor, fibroblast growth factor 2, platelet-derived growth factor AB (PDGF-AB), and platelet-derived growth factor AA (PDGF-AA) and the catabolic factors interleukin (IL) 1ß, IL-6, IL-8, and tumor necrosis factor α in LR-PRP were measured. Peripheral blood was drawn at 3 time points: baseline, after 1 week of naproxen use, and after a 1-week washout period. RESULTS: The angiogenic factors PDGF-AA (44% decrease in median) and PDGF-AB (47% decrease) significantly declined from baseline (P < .05) after 1 week of naproxen use. There was a significant recovery (P < .05) of PDGF-AA (94% increase) and PDGF-AB (153% increase) levels after the 1-week washout period, with a return to baseline levels. The catabolic factor IL-6 also had a significant decline from baseline (77% decrease in median, P < .05) after 1 week of naproxen use. After a 1-week washout period, the IL-6 level was similar to the baseline level (130% increase, P < .05). CONCLUSIONS: Naproxen use diminished several biological factors in LR-PRP; however, a 1-week washout period was sufficient for the recovery of PDGF-AA, PDGF-AB, and IL-6 to return to baseline levels. Tumor necrosis factor α, IL-1ß, IL-8, vascular endothelial growth factor, and fibroblast growth factor 2 did not show differences between the 3 time points of data collection. Discontinuing NSAIDs for a minimum of 1 week before LR-PRP treatment may improve certain biological factor levels. LEVEL OF EVIDENCE: Level II, prospective comparative study.

Arthroscopic Management of Glenohumeral Arthritis: A Joint Preservation Approach.

Treatment of young, active patients with primary glenohumeral osteoarthritis (GHOA) is challenging because shoulder arthroplasty may not be ideal in this population. In the past two decades, joint-preserving arthroscopic management options for GHOA, including débridement, have been used to treat different pathologies related to GHOA to reduce pain, to improve function, and to delay or even avoid arthroplasty. Key aspects of comprehensively addressing GHOA arthroscopically include chondroplasty, synovectomy, loose body removal, humeral osteoplasty with excision of the goat's beard osteophyte, capsular release, subacromial and subcoracoid decompression, axillary nerve decompression, and biceps tenodesis. Although data are still emerging, clinical studies report that an arthroscopic approach to glenohumeral arthritis using these various procedures reduces pain, improves function, and improves clinical outcome scores in the short- to mid-term follow-up period. Additional high-level studies are warranted to evaluate long-term outcomes and durability following this procedure.

Return to Recreational Sporting Activities Following Total Shoulder Arthroplasty.

BACKGROUND: Patients are staying active longer and expect to return to sports or continue participating in recreational activities after total shoulder arthroplasty (TSA) for primary glenohumeral osteoarthritis. PURPOSE/HYPOTHESIS: The purpose of this study was to assess the ability of patients to return to recreational sports following TSA. We hypothesized that TSA would allow a high rate of return to recreational sports. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: All patients who underwent primary TSA by a single surgeon and were at least 2 years out from surgery were included and were studied for their ability to return to recreational activity following surgery between December 2005 and January 2015. Patient-reported outcomes were obtained, including the 12-Item Short Form Health Survey-Physical Component Summary (SF-12 PCS); Single Assessment Numeric Evaluation (SANE); Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire; American Shoulder and Elbow Surgeons (ASES) score; and satisfaction scores (10-point scale), preoperatively and at a minimum of 2 years postoperatively. Return-to-sport rates were assessed using a standardized patient-reported outcome questionnaire. RESULTS: A total of 165 patients (186 shoulders) that received TSA met the inclusion criteria for the study. Preoperatively, 139 patients (157 shoulders) were involved in recreational sports; 16 (8.6%) shoulders required additional surgical intervention after the index TSA procedure. A significant postoperative increase was noted in the mean ASES (from 48.3 to 87.0; P < .001), QuickDASH (from 41.0 to 15.8; P < .001), SANE (from 49.1 to 81.2; P < .001), and SF-12 PCS scores (from 38.6 to 48.9; P = .004). Of the 157 shoulders in the recreational sports cohort, responses to the survey examining recreational sporting activities after surgery were available for 112 shoulders. The overall rate of return to sport or recreational activity following TSA was 93.7% (105/112 shoulders). The rate of return to recreational sporting activity equal to or better than the preinjury level was 69.7% (78/112 shoulders), while 6.3% (7/112 shoulders) of our cohort reported that they were unable to compete in recreational sports following TSA. Of the patients who participated in predominantly upper extremity sporting activities after TSA, 49% had to modify their postoperative recreational sporting activity because of lifestyle change, pain, weakness, or decreased range of motion. CONCLUSION: Patients undergoing TSA showed excellent postoperative improvement in their outcome scores, satisfaction, and return to athletic activities. Despite the expected decrease in activity levels with the slow progression of osteoarthritis over time until TSA was performed, almost 94% of patients successfully returned to various recreational sporting activities postoperatively. This study showed that return to recreational sports can be achieved at participation levels that are comparable with preoperative levels, but athletes in some sports such as tennis or swimming, which require more intense levels of exercise, are less likely to return to the same participation levels.

Allograft Use in Shoulder Surgery: Instability and Rotator Cuff.

Shoulder instability and rotator cuff pathology can provide a challenging problem, especially in the revision setting. Allograft use in primary or revision surgical intervention for shoulder instability and rotator cuff tear may be a valuable resource. This paper reviews allograft tissue use in shoulder surgery for instability and rotator cuff tear.

Career Length and Performance Among Professional Baseball Players Returning to Play After Hip Arthroscopy.

BACKGROUND: Hip arthroscopy has been shown to be effective for management of symptomatic femoroacetabular impingement (FAI) in professional athletes; however, it is unclear how hip arthroscopy affects career length and performance when professional baseball players return to play. PURPOSE: To determine the career length, performance, and return-to-play rates of professional baseball players after undergoing arthroscopy for symptomatic FAI. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Forty-four professional baseball players (51 hips) underwent hip arthroscopy for FAI between 2000 and 2015 by a single surgeon. Data were retrieved for each player from MLB.com , MiLB.com , Baseballreference.com , and individual team websites. Age, surgical procedure, and intraoperative findings were also used in analysis. Return to play was defined as playing in a preseason or regular season major or minor league game after arthroscopy. Career length was measured as total years played before and after arthroscopy. Performance measures included earned run average for pitchers, batting average for position players, and games played for all players. RESULTS: Of the 44 players, there were 21 pitchers and 23 position players. Ninety-five percent (n = 42) were able to return to professional baseball after hip arthroscopy. The mean career length for all players was 9.5 years. The mean career length after return to play was 3.6 seasons (range, 1-14 seasons). Pitchers had a mean career length of 8.7 years (3.3 after surgery), and position players averaged a career length of 10 years (3.9 after surgery). There were no differences in performance measures between preinjury and postoperative values. CONCLUSION: Professional baseball players undergoing hip arthroscopy for FAI returned to sport and had similar performance as they did before injury. The average career length was 9.5 years. In our study cohort, more pitchers than position players underwent hip arthroscopy. Hip arthroscopy appears to be an effective surgical intervention, allowing for return to play after complete recovery.
