Background: Concussions have previously been shown to have persistent neurological changes represented by altered reaction time and postural stability in high-level athletes. The effects of concussions on professional basketball players’ performance and subsequent injuries during the 90 days after return to play (RTP) have not been investigated. Purpose/Hypothesis: the purpose of this study was to evaluate player statistical performance and risk of musculoskeletal (MSK) injury within 90 days of RTP from a diagnosed concussion. It was hypothesized that within the 90 days after RTP from a concussion, players would be at a greater risk for MSK injury with an associated decrease in player statistical performance. Study Design: Descriptive epidemiology study. Methods: Concussions sustained by National Basketball Association (NBA) players between the 2015-2016 and 2021-2022 seasons, excluding the 2019-2020 season, were evaluated using a publicly available database. The database was queried to identify any MSK injury in the 90-day post-RTP period after a concussion, along with time loss after subsequent injury. Performance statistics were obtained from each player’s preindex season and postindex season, as well as defined time points within the 90-day post-RTP period. Each concussed player was matched 1 to 1 with a nonconcussed control using position, win shares, player efficiency rating, and points per game. MSK injury incidence and player statistics in the concussion group were compared with controls using unpaired Student t tests. Results: A total of 70 concussions were identified in 70 professional basketball players and included in this analysis. A total of 49 players sustained an MSK injury in the 90-day post-RTP period (70%). Compared with controls, the odds of sustaining an MSK injury in the concussed cohort were 11.3 times greater (95% CI, 5.04-25.2; P < .001). Games missed after subsequent MSK injury were similar between the concussed and control groups ( P = .687). Comparisons over the 90-day post-RTP period did not reveal any significant changes in points per game, minutes per game, or true shooting percentage ( P > .05). When compared with controls, no changes in performance statistics were significantly different ( P > .05). Conclusion: Our analysis demonstrates that basketball players who sustain concussions are at a significantly increased risk for subsequent MSK injury within the 90-day post-RTP period but not player performance. Knowledge of this increased risk of MSK injury in concussed athletes can help guide concussion management for proper RTP and targeted rehabilitation in professional basketball players.

Background: It has been demonstrated that an athlete’s psychological readiness contributes to one’s ability to successfully return to sport (RTS) after anterior cruciate ligament (ACL) reconstruction. However, the effect of graft choice on psychological readiness is not yet understood. Purpose/Hypothesis: The purpose of this study was to evaluate the association between graft choice and an athlete’s psychological readiness to RTS. It was hypothesized that similar ACL-Return to Sport after Injury (ACL-RSI) scores would be achieved among patients who underwent ACL reconstruction with quadriceps autograft (QA), hamstring tendon autograft (HA), and bone–patellar tendon–bone (BTB) autograft. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary ACL reconstruction at a single institution between January 2017 and December 2018 were placed into separate cohorts depending on graft type (HA, BTB, or QA; n = 30 patients in each group), and the ACL-RSI, International Knee Documentation Committee subjective form, and Lysholm scores were compared between the different graft cohorts at 6 months postoperatively, at RTS, and at 2 years postoperatively. Also, the rate of patients who achieved an ACL-RSI score of ≥65 (predictive of return to preinjury sport at 2 years postoperatively) was calculated, as was the RTS rate and time. Results: The QA group demonstrated significantly higher ACL-RSI scores than both the HA and BTB groups at 6 months postoperatively ( P < .0001) and RTS ( P = .011). The QA group also had a higher rate of achieving ≥65 on ACL-RSI than the other groups at 6 months postoperatively ( P = .002) and RTS ( P = .024). There was no significant difference in the RTS rate between the 3 groups, although the QA group demonstrated a significantly quicker return (QA, 8.1 months; BTB, 9.6 months; HA, 10.5 months; P < .001). Conclusion: Athletes undergoing primary ACL reconstruction with QA achieved a higher mean ACL-RSI score and more often achieved a score of ≥65 at the 6-month and RTS time points compared with the HA and BTB groups. QA may afford an advantage over other grafts in terms of improved psychological readiness to RTS.

Purpose To compare the surgical outcomes of anterior cruciate ligament (ACL) reconstruction using hamstring autograft (HA) plus lateral extra‐articular tenodesis (LET), isolated all‐soft tissue quadriceps autograft (QA), and isolated HA. Methods A retrospective review was performed comparing high‐risk patients undergoing ACL reconstruction with isolated HA, isolated QA, or HA + LET from August 2013 to January 2023. High‐risk patients, as determined by high‐grade pivot shift or generalized ligament laxity, with at least a 2‐year follow‐up, were included. Lysholm and International Knee Documentation Committee scores were compared at 3, 6, 12, and 24 months postoperatively. Retear rate, postoperative pivot‐shift grade, return to sport, and complications were recorded. Results In total, 159 patients (56 HA, 47 HA + LET, and 56 QA) were included. At 6 months postoperatively, the HA International Knee Documentation Committee score was significantly lower than that of the HA + LET and QA groups ( P < .0001). Similarly, the Lysholm score was significantly lower in the HA cohort at 6 months, 1 year, and 2 years postoperatively ( P < .0001‐.02). There was no difference in the rate of achieving the minimally important clinical difference between the cohorts for either of these outcome scores. The retear rate was significantly higher in the HA group (17.9%) compared to the HA + LET (4.3%) and QA (1.8%) cohorts ( P = .01). The rate of postoperative pivot shift of grade 2 or more was also higher in the isolated HA group ( P = .04). Conclusions The use of an all‐soft tissue QA or HA + LET for ACL reconstruction resulted in a lower retear rate and postoperative pivot‐shift grade compared to an isolated HA graft in high‐risk patients at 2 years postoperatively. There was no difference in the rate of achieving the minimal clinically important difference between the cohorts. The QA and HA + LET reconstruction options may improve stability and decrease the failure rate compared with HA reconstruction alone. Level of Evidence Level III, retrospective cohort study.

Background Value-based care payment and delivery models such as the recently implemented Merit-based Incentive Payment System (MIPS) aim to both provide better care for patients and reduce costs of care. Gender disparities across orthopaedic surgery, encompassing reimbursement, industry payments, referrals, and patient perception, have been thoroughly studied over the years, with numerous disparities identified. However, differences in MIPS performance based on orthopaedic surgeon gender have not been comprehensively evaluated. Questions/purposes After controlling for potentially confounding variables such as experience, geography, group size, and Medicare beneficiary characteristics, does MIPS performance differ between men and women orthopaedic surgeons? Methods The Medicare Physician and Other Practitioners and the Physician Compare databases were queried for years 2017, the first year MIPS was incorporated, and 2021, the most recent year with MIPS data published, to identify all physicians with a self-reported specialty of orthopaedic surgery. Together, these databases include all physicians who submitted at least 11 Medicare claims each year. Physician gender, US census region, years in practice, group practice size, billing practices, and patient demographic characteristics were collected for each surgeon. The MIPS Performance database was used to extract an overall MIPS performance score for each surgeon for each year. Payment adjustments, which are determined based on overall MIPS performance score, were derived for each surgeon based on the thresholds published by the Centers for Medicare & Medicaid Services. Payment adjustments include a negative adjustment, neutral adjustment, positive adjustment, or exceptional performance bonus and are associated with different thresholds each year. Statistical differences based on surgeon gender were assessed utilizing chi-square tests for categorical data, Student t-test for parametric continuous data, and Wilcoxon signed-rank test for nonparametric continuous data. Univariable and multivariable analyses were performed to analyze the relationship between surgeon gender and MIPS performance. Results After controlling for other patient and surgeon variables, woman gender was associated with a slightly increased MIPS performance score in 2021 (β 1.5 [95% confidence interval (CI) 0.02 to 3.00]; p = 0.047). However, this finding was statistically fragile, with the lower bound 95% CI being very close to the line of no difference. No association between surgeon gender and MIPS performance score was found in 2017 (β 2.2 [95% CI -0.5 to 4.9]; p = 0.11). Additionally, no relationship was found between gender and receiving either an exceptional performance MIPS bonus or a MIPS penalty in either year. Conclusion Women orthopaedic surgeons scored slightly higher on the MIPS in 2021, after controlling for surgeon and patient variables, despite providing care for a higher percentage of dual Medicare-Medicaid eligible patients and more medically complex patients. However, this finding was statistically fragile, with a small effect size, a 95% CI close to 0, and no consistent association in MIPS performance in 2017. Additionally, with no differences in MIPS performance bonuses or penalties, the clinical monetary impact of this difference may be minimal. Clinical Relevance The observed association between surgeon gender and MIPS performance scores in 2021, with women orthopaedic surgeons achieving slightly higher scores, raises interesting questions about potential differences in practice behaviors, communication styles, care quality, or other unmeasured variables. These findings may reflect true differences in how care is delivered or documented as scored by the MIPS. However, given the small effect size, statistical fragility, and inconsistency across years, there is a chance that this finding may be spurious. That being so, future research should aim to validate or refute these findings by examining a broader range of variables including documentation practices, practice behaviors, institutional differences, potential systemic biases in scoring methodologies, and patient outcomes. Understanding whether these differences are true is important to ensure that performance metrics like MIPS accurately and equitably reflect care quality.

Purpose To compare Medicaid and Medicare rates for the 20 most commonly billed orthopaedic sports medicine procedures. Methods Medicaid reimbursement rates were obtained from state‐specific fee schedules. Medicare rates were collected from the Centers for Medicare & Medicaid Services Physician Fee Schedule, along with relative value units for each procedure. State rates were compared using averages and dollar differences. Reimbursement rates were adjusted for cost of living using the Medicare Wage Index. Variability between states and between procedures was assessed using coefficients of variation. Results Mean Medicaid reimbursement was lower than that of Medicare for 19 of the 20 procedures. In total, Medicaid reimbursed surgeons 14.9% less when data were unadjusted and 26.0% less when data were adjusted for cost of living. Variation in Medicare rates between states was constant, with a coefficient of variation of 0.06. For Medicaid, the coefficients of variation ranged from 0.27 to 0.70 for unadjusted data and from 0.35 to 0.69 for adjusted data. Conclusions On average, Medicaid reimburses orthopaedic sports medicine specialists less than does Medicare, with substantial variability between states. Adjustment for cost of living increases the percentage difference and the variability between states’ Medicaid reimbursement rates. Level of Evidence Level IV, economic analysis.

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.

OBJECTIVES: This study seeks to evaluate the variability of Medicaid reimbursement and compare it with Medicare reimbursement using the 20 most commonly billed orthopaedic trauma Current Procedural Terminology (CPT) codes nationwide. The authors anticipate significant variability between states and hypothesize that Medicaid payment will be significantly less than Medicare payment. METHODS: The top 20 most common orthopaedic trauma surgery procedural codes were identified from a previous analysis performed by Haglin et al. The Centers for Medicare and Medicaid Services Physician Fee Schedule was used to determine reimbursement rates from Medicare, and state Medicaid fee schedules were used to determine reimbursement rates for Medicaid. State Medicaid rates were compared with their corresponding Medicare rates to determine a dollar difference. In addition, the dollar difference for each CPT code was divided by its respective physician relative value unit. This was used to acknowledge the possible variability in the complexity of orthopaedic procedures and the related physician effort. The Medicare Wage Index was used to adjust Medicaid rates based on the cost of living for the state as well. Coefficients of variation were calculated to represent overall variability in Medicaid and Medicare reimbursement rates. RESULTS: The mean reimbursement rates for Medicaid were lower for all 20 procedures compared with Medicare. On average, Medicaid reimbursed 16.0% less than Medicare and 29.6% less when adjusting for cost of living. MCD reimbursed at a higher rate than MCR for all procedures in only 9 states (Alaska, Arizona, Arkansas, Montana, Nebraska, New Jersey, New Mexico, North Dakota, and South Dakota) while 38 states reimbursed at a lower rate than MCR, on average. The coefficient of variation ranged from 0.24 to 0.34 for the Medicaid unadjusted group and from 0.35 to 0.46 for the Medicare Wage Index–adjusted group. By contrast, the Medicare group was consistent at 0.06 for all 20 procedures. The average dollar difference across the 20 CPT codes for Medicaid reimbursement compared with Medicare reimbursement ranged from −$76.89 to −$225.17, and the dollar difference per relative value unit ranged from −$5.96 to −$15.16. CONCLUSIONS: This study found a high amount of variation between state Medicaid reimbursement rates and average rates that were significantly lower than Medicare reimbursement rates for the top 20 most used orthopaedic trauma CPT codes as identified by Haglin et al. The discrepancy in reimbursement was increased when Medicaid rates were adjusted for state cost of living. LEVEL OF EVIDENCE: Prognostic, Level III.

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.

Purpose To assess outcomes of arthroscopic posterior capsular release among athletes for loss of terminal extension following anterior cruciate ligament (ACL) reconstruction. Methods A retrospective review of prospectively collected data was performed for patients undergoing arthroscopic posterior capsular release for knee extension loss following ACL reconstruction between January 2014 and December 2019. Procedure indications included extension loss greater than 10° at least 3 months after ACL reconstruction that was refractory to physical therapy. Patients were included if they were involved in either high school or college athletics, had complete outcomes of interest, and had at least 2 years of follow‐up. Prospectively collected outcomes included preoperative and postoperative measurement of knee extension, International Knee Documentation Committee score, Lysholm score, return to sport data, and complications. Results Eighteen athletes with minimum 2 years of follow‐up who underwent posterior capsular release following ACL reconstruction performed by a single surgeon were included in the analysis. Patients underwent surgery at an average of 16 weeks after ACL reconstruction. Knee extension improved an average of 13.8° at 2 years’ follow‐up (prerelease mean extension deficit 15.1°, postrelease mean extension deficit 1.3°, P < .005). Improvements in the International Knee Documentation Committee score averaged 21.7 at 6 months and 35.0 at 24 months, both of which were statistically significant ( P < .001). Similarly, differences in Lysholm included a significant improvement of 23.0 and 34.2 at 6 months and 2 years, respectively ( P < .001). In total, 77.8% returned to sport at an average of 9.8 months from their primary ACL surgery and 6.5 months following posterior capsular release surgery. No infections or neurovascular complications were observed. One patient required secondary release to achieve adequate extension. Conclusions For athletes with persistent knee extension loss after ACL reconstruction, knee extension was significantly improved at 2 years following arthroscopic posterior capsular release. Substantial improvements in patient‐reported outcomes also were seen. In addition, subjects demonstrated a high rate of return to sport and return to preinjury performance levels.

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.
