Purpose To use the All of Us database to investigate barriers to health care access for patients with meniscus tears and to examine how specific demographic, socioeconomic, and health‐related factors independently influence their health care utilization. Methods The National Institutes of Health All of Us database was queried for patient data between March 2017 and March 2023 to form a cohort of patients with meniscal tears. Patients with meniscal tears were identified using Systematized Nomenclature of Medicine clinical terms. All patients with self‐reported meniscus tears were included, with no exclusion criteria to ensure a diverse representation of underrepresented individuals. Patient responses to the “Healthcare Access and Utilization Survey” were analyzed across 4 domains: “delayed care,” “could not afford care,” “skipped medication,” and “have not seen a provider in over one year.” Results In total, 5,671 survey respondents with meniscal tears were included for analysis from a population of 436,000 eligible records. Among them, 27.7% reported delayed care, 23.9% were unable to afford care, 11.8% skipped medication, and 2.0% had not seen a provider in over a year. Patients with annual incomes under $50,000 were more likely to delay care (odds ratio [OR], 1.41; P < .001), be unable to afford care (OR, 1.73; P < .001), or skip medications (OR, 1.79; P < .001). Younger age than the cohort mean of 65.4 years, female sex, and poor physical and mental health were associated with impaired access in at least 1 care domain. Conclusions Over one‐fourth of patients with a diagnosis of meniscus tear who responded to the All of Us “Healthcare Access and Utilization Survey” reported difficulties with access to care across 4 domains, with those of low income, younger age, female sex, and poor mental or physical health experiencing significant barriers to care. Clinical Relevance This research can inform strategies for equitable treatment of meniscal injuries by highlighting disparities in orthopaedic care access and utilization.

Background: Because of growing concerns regarding repeated head trauma, in 2016, the United States Soccer Federation (USSF) banned headers for athletes aged ≤10 years and limited athletes aged 11 to 13 years to practicing headers for 30 minutes per week. Purpose: To assess whether the USSF header policy was associated with fewer soccer-related concussions after the 2015 season. Study Design: Descriptive epidemiology study. Methods: A retrospective cohort from the National Electronic Injury Surveillance System database was assessed. Age, sex, and injury type were extracted for all soccer-related emergency department visits between January 1, 2012, and December 31, 2023. Univariate and multiple regression analyses were used to assess concussions as a percentage of all soccer-related injuries based on sex, age group (6-9, 10-13, and 14-17 years), and year. The following time frames were assessed: 2012-2015, 2016-2019, and 2020-2023. Results: The proportion of concussions decreased from 8.2% of all soccer-related injuries in 2012-2015 to 6.1% in 2020-2023 ( P < .01). The relative risk reduction for soccer-related concussions presenting to an emergency department in 2020-2023 compared with 2012-2015 was 25.6%. Overall, the proportion of concussions among 10- to 13-year-old and 14- to 17-year-old players was higher than for 6- to 9-year-old players (6.6% and 8.9% vs 4.9%, respectively; P < .01). Despite having a lower frequency of soccer-related injuries overall, female players had a greater proportion of concussions than male players (9.6% vs 6.2% of all soccer-related injuries; P < .01). In the multiple regression analysis, injuries that occurred in 2020-2023 were associated with lower odds of concussion compared with 2012-2015 (odds ratio [OR], 0.75 [95% CI, 0.69-0.81]). Compared with 6- to 9-year-old and male players, the 10- to 13-year-old (OR, 1.30 [95% CI, 1.16-1.45]), 14- to 17-year-old (OR, 1.79 [95% CI, 1.61-1.99]), and female players (OR, 1.53 [95% CI, 1.43-1.63]) were associated with higher odds of concussion. Conclusion: A 25.6% reduction in the relative risk of presenting to the emergency department with a soccer-related concussion was found when comparing 2020-2023 (after USSF header policy implementation) with 2012-2015 (before policy implementation). The USSF youth soccer header policy may improve player safety by reducing head impacts in the pediatric population.

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. Level of Evidence Level III, retrospective comparative study.

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.

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.
