Purpose To compare lower extremity soft tissue injury and revision surgery rates for patients with anorexia nervosa (AN) and bulimia nervosa (BN) compared with matched controls. Methods This retrospective cohort study used a deidentified claims database. Patients were included if they carried an International Classification of Diseases code for AN or BN. Respective matched cohorts for AN and BN were created using propensity score matching. Primary and revision surgeries for anterior cruciate ligament (ACL) reconstruction, posterior cruciate ligament reconstruction, knee collateral ligament reconstruction, meniscus repair or meniscectomy, and any ankle ligament reconstruction were identified by their CPT codes. Patients over the age of 40 and without a minimum 2‐year follow‐up after primary surgery were excluded. Differences in prevalence and revision rates were analyzed. Results A total of 56,146 patients with AN and 42,630 patients with BN were included in this study with equal numbers in respective matched cohorts. Patients with BN showed an increased risk of ACL injury (relative risk = 1.32, P = .019), medial collateral ligament injury (1.17, 0.04), calcaneofibular sprain (1.92, <0.001), deltoid sprain (1.41, 0.004), and unspecified ankle sprain (1.44, <0.001). Patients with AN showed an increased risk for calcaneofibular sprain (1.25, 0.007), deltoid sprain (1.28, 0.015), and unspecified ankle sprain (1.17, <0.001). Patients with BN were more likely to have revision ACL repair (1.89, 0.02), partial meniscus revision (3.44, <0.001) and any meniscus revision (4.74, <0.001) while patients with AN were more likely to have an ACL revision (2.81, <0.001), partial meniscus (4.37, <0.001), and any meniscus (4.52, <0.001). Conclusions In this study, patients with AN and BN had a significantly increased risk for various knee and ankle injuries and revision surgeries compared with matched controls. Additionally, patients with AN and BN who sustained these injuries were more likely to undergo a revision surgical procedure within the first 5 years of the primary procedure. Level of Evidence Level III, retrospective comparative study.

Abstract Background Little research exists regarding geographic comparisons within the United States for Medicaid reimbursement. We compared Medicaid reimbursement for a broad range of orthopedic surgery codes from each state on a geographic and state level. Methods We obtained Medicaid reimbursement rates in each state for 211 orthopedic procedure codes along with corresponding work Relative Value Units (wRVUs). Rates were divided by wRVUs to control for differences between procedures and subspecialties. States were designated as either West, Midwest, South, or Northeast. Kruskal-Wallis tests with Dunn’s post-hoc analyses ascertained differences between regions and each orthopedic subspecialty by state. Coefficient of variation (CoV) values were calculated to measure the amount of variability in rates. A Kruskall-Wallis with Dunn’s post-hoc test assessed differences in quartiles for reimbursement compared to a square miles per orthopedic surgeon ratio. Results The West region reimbursed the highest at $72.92/wRVU and the Northeast reimbursed the lowest at $51.78. Hand surgery was the highest reimbursing subspecialty ($94.58/wRVU) and Oncology the lowest ($62.89/wRVU). The CoV ranged from 0.15–0.77 by state and 0.27–0.50 by subspecialty. A linear regression model between wRVU-adjusted Medicaid reimbursement and square miles per surgeon yielded an R2 value of 0.453. States with the most land area relative to orthopedic surgeons reimbursed significantly higher. Conclusion The West geographic region is associated with the highest Medicaid reimbursement for orthopedic procedures, and the Northeast the lowest. Wide variability was seen in rates, both between states and within states. Large, sparsely-populated states may increase Medicaid reimbursement as a tactic to attract physicians.

Background: Simultaneous carpal tunnel release (sCTR) with emergent forearm fasciotomy in the setting of acute compartment syndrome (ACS) has been reported, but the national incidence and cost of delayed carpal tunnel release (CTR) remain unknown. This large database study aims to evaluate how often sCTR is performed, the frequency of delayed CTR when not performed simultaneously, and the associated costs. Methods: The PearlDiver Mariner database was queried for patients who underwent forearm fasciotomies between January 1, 2015, and October 31, 2022. Patients were grouped based on CTR timing: simultaneous, within 2 weeks, 2 weeks to 1 year, 1 to 5 years, or no CTR. Reimbursement data were collected, and patient numbers and costs were analyzed across cohorts. Results: More than half of patients undergoing emergent forearm fasciotomy received sCTR. Among those who did not, 31% required CTR within 1 year and 35% within 5 years. The total cost was highest when CTR was performed within 1 year but not on the same day as fasciotomy. After 1 year, the additional cost of CTR was similar to that of patients who never underwent fasciotomy. Conclusions: This large database study shows that over one-third of patients who did not undergo sCTR at the time of emergent forearm fasciotomy required it within 1 year, incurring significantly higher costs. Including sCTR during initial fasciotomy may reduce delayed care and associated expenses. While these findings suggest that including sCTR during initial fasciotomy may reduce delayed care and expenses, the retrospective design precludes definitive recommendations, and clinical judgment remains essential Level of Evidence: 4

» Affordable Care Act Medicaid expansion increased orthopaedic surgery access and utilization among Medicaid patients, including for racial and ethnic minorities. » Despite improved coverage, Medicaid patients continue to face significant real-world barriers to orthopaedic care, including lower appointment success and longer wait times compared with privately insured patients. » Evidence on cost and quality impacts remains limited, with early signals of increased reimbursements, higher charges, and some quality improvements postexpansion.

Introduction: Total knee arthroplasty (TKA) is a widely performed elective procedure globally. Periprosthetic joint infection (PJI) remains a serious complication following TKA. Hematogenous seeding from distant infections is a recognized mechanism of PJI. However, to our knowledge, there are no published reports of hematogenous PJI originating from acute epididymo-orchitis. Case Report: A 74-year-old male presented to the emergency department following a ground-level fall on his right knee. He was diagnosed with a knee effusion and discharged for outpatient follow-up. Approximately one week later, the patient presented to his primary care physician with right scrotal swelling and was diagnosed with epididymitis and started on oral antibiotics. The following day, he underwent right knee arthrocentesis which was positive for an acute PJI. The patient then underwent a double debridement, antibiotics and implant retention (DAIR) procedure and was discharged on a six-month course of oral antibiotics. Eight months after the double DAIR, the patient developed right knee swelling and erythema. Right knee aspiration was positive for a persistent PJI, and the patient underwent resection arthroplasty with insertion of an antibiotic spacer. Conclusion: Hematogenous spread of epididymoorchitis resulting in PJI is a rare and underreported complication that has not been fully understood in the literature. In this case, several risk factors—such as the presence of a prosthetic joint, recent trauma, and chronic corticosteroid use—may have increased the patient’s susceptibility to infection. Close monitoring of inflammatory markers such as C-reactive protein, erythrocyte sedimentation rate, and white blood cell count can aid in the early detection of septic arthritis and contribute to improved patient outcomes.

Background: The Centers for Medicare & Medicaid Services (CMS) Merit-based Incentive Payment System (MIPS) has undergone numerous changes to promote care for patients at high social risk. However, the effect of these changes on surgeon MIPS performance and caseload selection remains unclear. Thus, the purpose of this study was to evaluate how orthopaedic surgeon MIPS scores, demographics, practice characteristics, and patient populations varied on the basis of patient social risk in 2017 compared with 2021. Methods: CMS data were utilized to examine U.S. orthopaedic surgeons. Surgeons were placed into social-risk quintiles on the basis of the proportion of their patients who were dually eligible for Medicare and Medicaid, with the highest quintile representing the highest social risk. Demographics, practice location characteristics, patient data, and MIPS performance were assessed for the years 2017 and 2021. Differences between social-risk quintiles were assessed utilizing chi-square, Student t, and Wilcoxon signed-rank tests and multivariable logistic regression. Results: In 2017, surgeons with caseloads at the highest, compared with the lowest, social risk had lower MIPS performance scores (mean [and standard deviation], 66.0 ± 37.6 versus 70.1 ± 33.5; p < 0.001). However, in 2021, orthopaedic surgeons with caseloads at the highest, compared with the lowest, social risk had significantly higher MIPS performance scores (mean, 88.7 ± 16.9 versus 81.5 ± 18.3; p < 0.001). In terms of demographics, in 2021, orthopaedic surgeons with caseloads at the highest, compared with the lowest, social risk were more often women (9.2% versus 3.6%; p < 0.001), more often had a DO degree (11.2% versus 6.6%; p < 0.001), more recently graduated from medical school (mean, 23.0 ± 12.9 versus 25.7 ± 10.9 years; p < 0.001), and worked in areas with higher Distressed Communities Index (DCI) distress scores (mean, 56.9 ± 27.3 versus 35.1 ± 25.2; p < 0.001). Similar findings were present in 2017. Conclusions: The addition of the Complex Patient Bonus to the MIPS in 2020 may have reduced performance inequities in MIPS scoring for surgeons with caseloads at high social risk. However, the demographics and practice patterns of the orthopaedic surgeons caring for populations at the highest social risk remained consistent between years.

Background: Supracondylar humerus fractures (SCH) are the most common type of elbow fracture in children, with many cases requiring surgery. Treatment of postoperative pain for SCH has high variability, but can often be treated effectively with minimal or no opioids. Furthermore, there is significant morbidity related to pediatric opioid consumption. The goal of this study was to characterize prescription patterns in the United States following closed reduction and percutaneous pinning (CRPP) of SCH. Methods: All patients aged 10 or younger years who underwent CRPP of SCH from January 2010 to December 2021 were identified in the PearlDiver Mariner Claims Database. The primary outcome was postoperative pain medication prescriptions in the 30 days following SCH CRPP. Patient demographics, prescription duration, and morphine milligram equivalents (MME) were analyzed. Multivariable-log-binomial mixed regression models were constructed to assess factors associated with increased opioid prescription. Results: In total, 43,611 SCH CRPP cases in patients aged 10 or younger were identified from 2010 to 2021. Throughout the study period, 48.6% of patients (21,191/43,611) received and filled a narcotic pain prescription. The percentage of patients receiving opioid medication decreased from 54.7% in 2010 to 27.4% in 2021. Opioid prescriptions totaled a mean of 6.1±2.1 days of narcotics with a mean of 79.2 MME prescribed per patient. Increased patient age, increased Elixhauser comorbidity index, and Medicaid insurance were all associated with increased opioid prescription (P<0.001). Living in the Northeast, increased family income, and commercial insurance were associated with decreased opioid prescriptions (P<0.001). Conclusions: Nearly half of the patients over the past decade treated with CRPP for SCH received a narcotic prescription. However, there has been a steady decline in the proportion of patients being prescribed opioids, with only 27.4% receiving opioids in 2021. Further, patients with increased comorbidities or those insured by Medicaid with lower mean family income may be at risk for increased opioid prescription. While efforts have been made to reduce opioid overprescribing, there continues to be room for further reduction in opioid utilization after CRPP for SCH moving forward.

Background: The number of multiply revised anterior cruciate ligament reconstructions (rrACLRs) performed each year continues to increase. The most reliable graft type and surgical technique in the young, active patient remains to be determined. Purpose: To determine the outcomes of rrACLR using quadriceps tendon (QT) autograft with lateral extra-articular tenodesis (LET). Study Design: Case series; Level of evidence, 4. Methods: A retrospective review was performed of all competitive athletes undergoing rrACLR with QT autograft and LET at a single institution with a minimum follow-up of 2 years. Patient demographics, physical examination, and radiological findings, and previous surgical details were documented. Patient outcomes were noted, including the International Knee Documentation Committee (IKDC) and Lysholm scores, ability to return to sport and return at the same level of play, retear rate, and other complications. Results: A total of 19 rrACLRs were performed and met inclusion criteria in the 10-year study period. All participants were high school, collegiate, or professional athletes with a mean age of 22 years, and 63.2% were female. The mean follow-up was 42.3 months, and IKDC scores increased from 51.6 preoperatively to 74.7 at the final follow-up ( P < .001). Likewise, the Lysholm score increased significantly from a preoperative value of 53.6 to 76.8 at the final follow-up ( P < .001). Return to play was possible in 52.6% of the patients at a mean of 11.5 months, with 31.6% returning to the same or higher level of play. One (5.3%) patient experienced a recurrent ACL tear, and 2 (10.5%) experienced a contralateral tear. Arthrofibrosis requiring surgical intervention occurred in 26.3% of the athletes. Conclusion: Short- to midterm results demonstrated that competitive athletes who received an rrACLR using a QT autograft with LET had statistically significant improvements in both IKDC and Lysholm scores, with more than half of patients being able to return to sport and nearly a third returning at the same or higher level of play. In the setting of a third ACL reconstruction, quadriceps tendon autograft with LET is a reasonable option even in high-risk patients.

Background: Medicaid reimbursement to physicians is often perceived to be lower than Medicare, but little is known about orthopaedic foot and ankle reimbursement. This study sought to compare Medicare and Medicaid reimbursement for the 20 most common foot and ankle procedures. Methods: Medicare reimbursement rates for common foot and ankle codes were obtained from the online Centers for Medicare & Medicaid fee schedule, while Medicaid rates were found from individual state fee schedule websites. Medicaid rates were compared by state and pooled to obtain national differences. The Medicare Wage Index was used to adjust Medicaid rates by state wages to ensure a more accurate comparison. Variability between states was measured using state percentages of Medicare and coefficient of variation values. Results: Medicaid reimbursed physicians higher than Medicare in 31 states overall, with average reimbursement ranging from 37% to 324% of Medicare. Nationally, Medicaid reimbursed 8.8% higher than Medicare, but Medicare reimbursed 3.7% higher when adjusted for the Medicare Wage Index. The Current Procedural Terminology ( CPT ) codes with the highest ratio of Medicaid to Medicare reimbursement were CPT 28002 for incision and drainage of the foot (176.6%) and CPT 28820 for toe amputation (167.6%). Five codes had lower relative Medicaid reimbursement on average: CPT 27687 for repair procedures on the leg and ankle joint, CPT 28810 for amputation procedures on the foot and toes, CPT 28010 for toe tenotomy, CPT 28005 for incision procedures on the foot and toes, and CPT 28470 for closed treatment of a metatarsal fracture. The coefficient of variation values ranged from 0.34 to 0.84 in the Medicaid group and 0.40 to 0.78 in the adjusted group, indicating high variability between states and between procedures. Conclusion: Medicaid reimbursement is highly inconsistent between states, ranging from 37% to 324% of Medicare. Medicaid reimbursed more than Medicare overall, which is in contrast with most published findings that tend to show higher reimbursement for Medicare when compared to Medicaid. When adjusting for wage differences between states, Medicare reimbursed slightly higher than Medicaid. Level of Evidence: Level IV, economic analysis.

Background: The purpose of this study was to investigate the association between cannabis use and postoperative complications following ankle and hindfoot arthrodesis. Methods: A retrospective cohort study using a large national insurance database from 2010 to 2022 was conducted. All patients who underwent ankle or hindfoot arthrodesis with at least 2 years’ follow-up were included. Patients were divided into 4 groups: cannabis-only users, tobacco-only users, cannabis and tobacco users, and nonuser controls. Groups were matched 1:4 with nonuser controls based on demographic variables and comorbidities. Also, both cannabis and tobacco users were matched 1:4 with tobacco-only users based on demographics and comorbidities. Medical complications within 90 days of surgery and surgery-specific complications within 2 years were compared between groups with multivariable logistic regressions. Results: Compared with nonuser controls, cannabis users only were not at increased risk of 90-day medical complications or 2-year surgical complications. Tobacco use alone was associated with increased risk of postoperative admission (OR 1.32, 95% CI 1.21-1.43) and emergency department (ED) utilization (OR 1.57, 95% CI 1.48-1.66) within 90 days as well as infection (OR 1.24, 95% CI 1.18-1.30), hardware removal (OR 1.12, 95% CI 1.07-1.18), nonunion (OR 1.33, 95% CI 1.27-1.40), and wound dehiscence (OR 1.38, 95% CI 1.27-1.49) within 2 years of surgery compared with nonuser controls. Compared with tobacco-only use, combined cannabis and tobacco use was associated with increased risk of ED visits within 90 days (OR 1.45, 95% CI 1.30-1.62) and nonunion within 2 years of surgery (OR 1.19, 95% CI 1.05-1.35). Conclusion: These findings suggest that although cannabis use alone was not associated with a higher risk of postoperative complications, its concurrent use with tobacco was linked to greater rates of adverse outcomes. Level of Evidence: Level III, retrospective case control study.
