Abstract Glenoid bone loss is a common sequela of recurrent anterior shoulder instability. When treated surgically, a bone augmentation procedure is more likely to provide a good outcome with a lower risk of recurrent instability compared with a soft‐tissue repair alone. There are several bone augmentation options to address glenoid bone loss, including coracoid transfer, iliac crest autograft, and distal tibial allograft (DTA). Both open and arthroscopic DTA techniques have been described using the lateral one‐third of the distal tibia oriented with the anterior aspect placed superiorly on the anterior glenoid. This graft orientation places its concavity in the superior‐to‐inferior direction. It may be preferred to have this concavity maximized toward the anterior direction so that it can further resist anterior displacement. The posterior one‐third of the distal tibia may provide a more optimal arc of resistance. However, no previous technique has used the posterior one‐third of the distal tibia to reconstruct the “half‐pipe” concavity of the anterior glenoid. We describe an all‐arthroscopic technique for a posterior third DTA oriented with the posterior tibial edge placed anteriorly on the glenoid, termed the “congruent‐arc DTA,” to address anterior shoulder instability with bone loss.

Purpose To characterize the relationship between testosterone replacement therapy (TRT) and anterior cruciate ligament (ACL) injuries. Methods A retrospective cohort study using a large insurance database was conducted. Patients who were prescribed TRT for at least 3 months were matched with controls who were not prescribed TRT. Rates of ACL tears were compared between the cohorts. Multiple subgroups were created based on age (<25, 25‐35, 36‐45, 46‐55, 56‐65, and 65+ years). Multivariable logistic regressions were performed to determine the association of TRT with ACL tears while accounting for demographic variables and comorbidities. Results After matching, there were 160,839 patients in both the TRT cohort and the control cohort. The incidence of ACL injuries was 17.8 per 10,000 person‐years (95% confidence interval [CI]: 16.4‐19.2) for patients who were prescribed TRT and 4.9 per 10,000 person‐years (95% CI: 4.1‐5.7) for controls ( P < .001). Within 2 years of filling a testosterone prescription for at least 3 months, 572 (0.35%) patients experienced an ACL injury compared to only 157 (0.10%) controls during the same follow‐up period (odds ratio: 2.77; 95% CI: 2.26‐3.42, P < .001). When stratified by age, all groups except the <25 years of age group demonstrated a significantly higher rate of ACL tears (odds ratio 3.91‐12.3, P < .001‐.009). When separated by sex, males on TRT were 3.13 (95% CI: 2.50‐3.93, P < .001) times more likely while females on TRT were 1.94 (95% CI: 1.13‐3.41, P = .018) times more likely to experience an ACL injury compared to controls. Conclusions This study found that patients prescribed at least 3 months of TRT had a significantly higher incidence of ACL injuries compared to controls within a 2‐year follow‐up period.

Purpose To determine whether long‐term preoperative nonsteroidal anti‐inflammatory drug (NSAID) use affected the revision rates after primary tendon repair for the following common sports medicine surgical procedures: rotator cuff repair (RCR), Achilles tendon repair (ATR), distal biceps repair (DBR), or quadriceps tendon repair (QTR). Methods A retrospective comparative study using a national insurance database was performed. Patients who underwent major tendon repair, including RCR, ATR, DBR, or QTR, with at least 2‐year follow‐up were identified. Those who had a diagnosis of long‐term NSAID use prior to the index operation were identified and matched 1:4 to controls without NSAID use based on age, sex, specific tendon repaired, and Elixhauser Comorbidity Index. The revision repair rates of the 2 groups were compared. Results A total of 36,068 patients underwent major tendon repair. Of these, 7,246 (20%) met the long‐term NSAID use criteria prior to tendon repair (NSAID users). After RCR, 3.2% of NSAID users (n = 190) and 2.6% of controls (n = 617) underwent revision surgery within 2 years (odds ratio [OR], 1.15; 95% confidence interval [CI], 0.97‐1.36; P = .10). After ATR, NSAID users had a revision rate of 3.9% (n = 24) versus 2.5% (n = 62) in the control cohort (OR, 1.47; 95% CI, 0.89‐2.38; P = .12). After DBR, both NSAID users and controls had fewer than 11 revision cases (OR, 1.54; 95% CI, 0.49‐4.16; P = .42). After QTR, the revision rate was 5.9% (n = 30) for NSAID users compared with 4.8% (n = 95) for the control group (OR, 1.22; 95% CI, 0.77‐1.86; P = .38). None of the observed differences in revision rates between NSAID users and controls were significant. Conclusions Patients with a diagnosis of and coding for long‐term preoperative NSAID use do not have greater revision rates within 2 years of primary tendon repair than patients without this diagnosis.

Abstract A bony Bankart fracture is a common injury pattern in anterior shoulder instability. The fracture fragment size varies and the larger the fragment the more likely recurrent instability will occur. When a large bony Bankart fracture is present, surgical fixation is preferred. Both open and arthroscopic approaches exist with multiple fixation techniques including anterior‐to‐posterior screw fixation, suture anchor bridge fixation, and suture button fixation. Arthroscopic screw fixation is difficult, as the angle necessary to be parallel to the glenoid surface requires a far medial start point and places the nerve at risk. The use of a variable‐pitch, headless compression screw placed from posterior to anterior avoids these risks. We describe an arthroscopic technique for glenoid fixation using a posterior‐to‐anterior, cannulated, variable‐pitch headless compression screw for the treatment of an anterior BBF.

Purpose To assess surgeon reimbursement for common arthroscopic procedures, including arthroscopic meniscal debridement and arthroscopic rotator cuff repair, in patients with differing risk profiles within the Medicare population. Methods A publicly available Medicare database was used to identify all cases of arthroscopic meniscal debridement and arthroscopic rotator cuff repair procedures billed to Medicare from 2013 to 2020. The surgeon reimbursement from Medicare was collected and adjusted for inflation. All procedure episodes were split into 2 cohorts; those with a hierarchical condition category (HCC) risk score ≥1.5, and those with patient HCC risk scores <1.5. Reimbursement rates were compared between groups. Results From 2013 to 2020, a total of 624,077 meniscal debridement procedures and 567,794 arthroscopic rotator cuff repairs were billed to Medicare Part B. During this time, the mean adjusted surgeon reimbursement for arthroscopic rotator cuff repair decreased by 9.2% from 2013 to 2020. During the same time period, the adjusted mean surgeon reimbursement for arthroscopic both compartment meniscal debridement and single compartment meniscal debridement decreased by 7.9% and 9.9%, respectively. Throughout the study period, the mean HCC risk score increased from 1.19 in 2013 to 1.31 in 2020 ( P < .001). Across all years in the study, the sicker cohort had a significantly greater rate of all comorbidities and a greater mean body mass index ( P < .001 for all variables). The mean reimbursement across this cohort was lower for both rotator cuff repair ( P = .037) and meniscal debridement procedures ( P < .001) compared with the healthier cohort. Conclusions This study demonstrates that from 2013 to 2020, inflation‐adjusted surgeon reimbursement for arthroscopic rotator cuff repair and meniscal debridement decreased while patient complexity increased. Further, mean surgeon reimbursement was lower among patients with more complexity in comparison with their healthier counterparts for such procedures. Level of Evidence Level III, retrospective cohort study.

ABSTRACT Introduction: Medical conferences are an integral aspect of medical education as they allow attendees to stay up to date with recent advancements in medicine, to develop presentation and communication skills, and to network and establish connections with professionals in their field of interest. But, when the coronavirus disease 2019 (COVID-19) pandemic was declared in March 2020, face-to-face medical conferences were suspended, and conference organizers began shifting their meetings to virtual platforms. These new virtual conferences afforded medical residents and fellows the unique opportunity to attend conferences from the comfort of their own home or workplace; however, the virtual meeting platforms did not provide attendees with the same networking experiences as in-person conferences. Since the end of the COVID-19 public health emergency, medical conferences are now faced with the question of whether they should remain virtual, shift back to in-person meetings, or develop a hybrid model of both options. Thus, the purpose of this study was to analyze medical resident and fellow sentiments and preferences by comparing virtual and in-person conference formats. Methods: A voluntary electronic survey was distributed to medical residents and fellows across the United States through their program coordinators and directors. Results: The main findings of this study suggest that medical residents and fellows largely prefer in-person conferences (85%) as compared to a virtual format because of the networking opportunities afforded to them along with the development of camaraderie with their peers. The findings in this study suggest that the largest benefit in attending a virtual conference is the flexibility to attend from any location (79% important or very important), which offered convenience, flexibility, and comfort to participants (n = 100). Conclusion: These results support our hypothesis that despite the convenience and portability afforded by attending conferences virtually, medical residents and fellows still ultimately prefer to attend conferences in person. Overall, the findings in this study are of relevance to conference organizers in understanding the driving forces behind attendance and should be considered in determining meeting format.

Purpose To use Google trends to explore differences in public interest among types of anterior cruciate ligament (ACL) autografts, specifically quadriceps tendon, patellar tendon, and hamstring tendon autografts, between 2008 and 2019. Methods Data were obtained by querying Google Trends for key terms and phrases for online search data ranging from January 2008 to December 2019. Relative search volumes were created based on searches related to ACL reconstruction with comparative analysis generated for search terms related to quadriceps ACL, patellar tendon ACL, and hamstring ACL autografts. Statistical analysis included linear regression analysis, comparison of quarterly search volume trends over time, and comparison of cumulative annual search volumes for 2008 versus 2019. Results Linear models for respective search terms were statistically significant for the quadriceps ( P < .001) and patellar ( P = .007) tendon autograft groups but not the hamstring group ( P = .129). The quadriceps autograft group demonstrated a 12‐year search volume trend change of 0.56, which was significantly greater than the hamstring (0.07; P < .001) and patellar tendon (0.168; P < .001) groups. There was no significant difference in the trend change between hamstring and patellar tendon groups ( P = .20). Percent change in cumulative relative annual search volumes between 2008 and 2019 was 112% for the quadriceps tendon group, 12.9% for the hamstring group, and 18.6% for the patellar tendon group. Conclusions This study indicates a consistently increasing public interest in quadriceps tendon autograft for ACL reconstruction. The quadriceps autograft group demonstrated a significantly greater 12‐year online search volume, greater linear correlation, and larger percent change between 2008 and 2019 compared with patellar tendon or hamstring autograft groups. Clinical Relevance Awareness of patient perceptions has value in informing shared decision‐making, aligning patient expectations, and guiding areas of future research. Each of these has an impact on patient care. Being aware of patient interest and expectations is particularly important in areas with controversial or emerging research.

Background: There is limited evidence related to the effects of autograft type on functional performance after anterior cruciate ligament reconstruction (ACLR). Purpose/Hypothesis: This study aimed to compare biomechanical outcomes during a drop vertical jump (DVJ) between patients with a hamstring tendon (HT) autograft, quadriceps tendon (QT) autograft with bone block, QT autograft without bone block, and bone–patellar tendon–bone autograft at 6 months postoperatively in an adolescent population. The authors’ hypothesized there would be differences in DVJ biomechanics between athletes depending on the type of autograft used. Study Design: Controlled laboratory study. Methods: Patients aged 8 to 18 years who underwent primary ACLR were included for analysis. Kinematic and kinetic data collected during a DVJ using a 3-dimensional computerized marker system were assessed at 6 months after ACLR and compared with the uninjured contralateral limb. Results: A total of 155 participants were included. There were no significant differences in terms of age, sex, or affected leg ( P≥ .1973) between groups. The HT group was significantly associated with a larger knee valgus moment at initial contact compared with the QT group (28 × 10 –2 vs −35 × 10 –2 N·m/kg, respectively; P = .0254) and a significantly larger maximum hip adduction moment compared with the QT with bone block group (30 × 10 –2 vs −4 × 10 –2 N·m/kg, respectively; P = .0426). Both the QT with bone block (–12 × 10 –2 vs −3 × 10 –2 N·m/kg, respectively; P = .0265) and QT (–13 × 10 –2 vs −3 × 10 –2 N·m/kg, respectively; P = .0459) groups demonstrated significantly decreased mean knee extension moments compared with the HT group. Conclusion: The findings of this study suggest that utilizing an HT autograft resulted in a significantly increased knee valgus moment at initial contact compared with a QT autograft without bone block at 6 months after ACLR in adolescent patients performing a DVJ. A QT autograft was found to be associated with significantly decreased extensor mechanism function compared with an HT autograft. Clinical Relevance: This study adds unique kinematic and kinetic information regarding various ACLR autograft options and highlights the biomechanical deficits that should be taken into consideration in rehabilitation.

Purpose To evaluate how arthroscopic meniscectomy utilization, reimbursement, physician billing practices, and patient populations have changed within the Medicare population from 2013 to 2021 at a national level and regional level. Methods The Medicare Physician & Other Practitioners database was queried for all episodes of 2‐compartment and single‐compartment arthroscopic meniscectomy between 2013 and 2021. Utilization per 10,000 beneficiaries and average inflation‐adjusted reimbursement were assessed. Physician practice styles, measured through changes in the services billed, and Medicare beneficiary demographic characteristics were extracted each year. The Kruskal‐Wallis test was performed to compare regions. Results Between 2013 and 2021, two‐compartment meniscectomy utilization per 10,000 Medicare beneficiaries declined by 54.9% and single‐compartment meniscectomy utilization declined by 54.2%. Average reimbursement declined by 9.3% and 12.5% for 2‐compartment meniscectomy and single‐compartment meniscectomy, respectively. In 2021, the South had the highest utilization of both 2‐compartment (3.8/10,000) and single‐compartment (4.7/10,000) meniscectomies while having the lowest average reimbursement for 2‐compartment meniscectomy ($383.02, P < .001). Nationally, the average number of beneficiaries per surgeon performing single‐compartment meniscectomy declined by 3.8% whereas the average number of billable services performed per beneficiary increased by 46.6%. The comorbidity risk score of these patients decreased by 8.7%, with the West having the healthiest patients in 2021. Conclusions Meniscectomy utilization and reimbursement have been declining nationally within the Medicare population. Surgeons in the South performed the most meniscectomies while having among the lowest reimbursement. The practice patterns of surgeons performing meniscectomies have been changing, with surgeons performing nearly 50% more total billable services per beneficiary while performing fewer unique billable services. Additionally, the patient population of surgeons who perform meniscectomy was healthier in 2021 than in 2013. Clinical Relevance This study highlights changes in meniscectomy utilization and reimbursement over time in the face of changing evidence of meniscectomy use in elderly patients and new Medicare legislature regarding reimbursement.

Purpose To determine the incidence rates and associated risk factors of season‐ending injuries (SEIs) in the National Basketball Association (NBA) from the 2015‐20 seasons. Methods Publicly available records of active NBA players between the 2015‐16 and 2020‐21 seasons were reviewed to identify players with an SEI. In this study, SEI was classified as any injury that resulted in failure to return at least 5 games before the end of the team’s game schedule. Injury data from the 2019‐20 NBA season, shortened because of the coronavirus disease 2019 pandemic, were omitted. The primary outcome was the incidence of SEIs reported per 1,000 game exposures (GEs). Player demographics, basketball statistics, injury characteristics, and timing of injury were recorded. Secondary analysis, including bivariate analysis and multivariate logistic regression, was performed to investigate factors associated with having an SEI. Results In total, 196 players (15.6% of all players) sustained a combined 238 SEIs between the 2015‐16 and 2020‐21 seasons, indicating a rate of 1.74 SEIs per 1,000 GEs. When characterized by body part, knee injuries were found to be the most frequent SEI, at a rate of 0.47 injuries per 1,000 GEs. Accounting for potential confounders, having an SEI was significantly associated with more minutes per game played (odds ratio, 1.06, 95% confidence interval, 0.99‐1.01, P < .001). Conclusions SEIs occurred in 15.6% of players in this study, with an overall rate of 1.74 SEIs per 1,000 GEs. The most significant risk factor associated with injury was minutes per game. SEI was more likely to occur in the third and fourth quartiles of the NBA season than in the first or second quartile. Level of Evidence : Level III, retrospective comparative prognostic investigation.
