Declining Inflation-Adjusted Medicare Physician Fees: An Unsustainable Trend in Hip Arthroscopy.

INTRODUCTION: Although hip arthroscopy continues to be one of the most used arthroscopic procedures, no focused, comprehensive evaluation of reimbursement trends has been conducted. The purpose of this study was to analyze the temporal Medicare reimbursement trends for hip arthroscopy procedures. METHODS: From 2011 to 2021, the Medicare Physician Fee Schedule Look-Up Tool was queried for Current Procedural Terminology (CPT) codes related to hip arthroscopy (29860 to 29863, 29914 to 29916). All monetary data were adjusted to 2021 US dollars. The compound annual growth rate and total percentage change were calculated. Mann-Kendall trend tests were used to evaluate the reimbursement trends. RESULTS: Based on the unadjusted values, a significant increase in physician fee was observed from 2011 to 2021 for CPT codes 29861 (removal of loose or foreign bodies; % change: 3.49, P = 0.03) and 29862 (chondroplasty, abrasion arthroplasty, labral resection; % change: 3.19, P = 0.03). The remaining CPT codes experienced no notable changes in reimbursement based on the unadjusted values. After adjusting for inflation, all seven of the hip arthroscopy CPT codes were observed to experience a notable decline in Medicare reimbursement. Hip arthroscopy with acetabuloplasty (CPT: 29915) and labral repair (CPT: 29916) exhibited the greatest reduction in reimbursement with a decrease in physician fee of 24.69% ( P < 0.001) and 24.64% ( P < 0.001), respectively, over the study period. DISCUSSION: Medicare reimbursement for all seven of the commonly used hip arthroscopy services did not keep up with inflation, demonstrating marked reductions from 2011 to 2021. Specifically, the inflation-adjusted reimbursements decreased between 19.23% and 24.69% between 2011 and 2021.

Femoral Version May Impact Hip Arthroscopy Outcomes in Select Patient Populations: A Systematic Review.

PURPOSE: To provide further clarity regarding the management of patients with abnormal femoral version in the setting of hip arthroscopy and will discuss the definition of femoral version, the diagnostic and clinical evaluation of abnormal femoral version, and several described measurement techniques. METHODS: A systematic review was conducted in literature published before August 2021 that measured femoral version and reported patient-reported outcomes measures or rates of subsequent procedures following hip arthroscopy. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and the electronic databases, PubMed, OvidMedLine, Scopus, and Web of Science were searched. Two blinded reviews screened and evaluated data quality using the Newcastle-Ottawa Scale. RESULTS: Eighteen studies were included with 11 studies reporting patient outcomes and 7 studies reporting rates of subsequent procedures. The most commonly used definition of femoral version was 5° to 20° of femoral anteversion. Computed tomography scan was the most commonly used imaging modality. The majority of studies (7 of 11) demonstrated that femoral version does not have an impact on patient-reported outcomes measures and is not predictive of clinically meaningful improvement scores. However, in select studies, patients with femoral retroversion were found to experience slightly inferior outcomes following hip arthroscopy for femoroacetabular impingement. While femoral retroversion may be a risk factor for subsequent procedures, 3 of 7 studies refute this claim. Although in patients with borderline hip dysplasia, excessive femoral anteversion led to greater rates of subsequent hip procedures. CONCLUSIONS: While the majority of studies show that femoral version does not have an impact on patient-reported outcomes following hip arthroscopy, those with femoral retroversion and with excessive anteversion with coexisting borderline hip dysplasia need to be educated on their increased risk of subsequent operation. Ultimately, this review suggests that clinical improvement can likely be achieved regardless of femoral version. LEVEL OF EVIDENCE: IV; systematic review of Level I-IV studies.

Comparison of time to healing and major complications after surgical fixation of nondisplaced femoral neck stress fractures: A systematic review.

INTRODUCTION: There is no recent literature review comparing outcomes of fixation methods for nondisplaced stress fractures of the femoral neck. METHODS: A systematic review of the literature on operative fixation of femoral neck stress fractures was performed. Inclusion criteria consisted of diagnosis of nondisplaced femoral neck stress fractures, implants used for fixation, articles in English language or available English translation, all ages, and Level 1-5 evidence, documented time to healing, and incidence of complications. Statistical analysis was performed to compare outcomes. RESULTS: Eight studies with 13 subjects and 15 fractures undergoing operative fixation were included. Six fracture were compression sided, five were tension sided, and four were complete. Radiographic healing occurred on average at 32.7 ± 36.3 weeks (range 8-121 weeks). Four subjects were noted to have a metabolic disturbance. Six subjects did not participate in vigorous exercise. There were no complications. There was no significant difference in radiographic healing time between: cannulated screws or SHS ± osteotomy (p = 0.21); compression sided, tension sided, or complete fractures (p = 0.41); ages (p = 0.09); sex (p = 0.09) or individuals with or without metabolic disturbances (p = 0.92). There was no difference between use of cannulated screw fixation, SHS + osteotomy, and SHS alone based on the subject's age (p = 0.27) or cannulated screw vs SHS ± osteotomy given subject's age (p = 0.19) or sex (p = 1.0). Time to full weight bearing (FWB) did not significantly differ between implants (p = 0.22). However, >8 weeks restricted weight bearing had increased healing times (p = 0.002). DISCUSSION: Time to healing was not dependent on subjects' sex or age, fracture location, implant choice, or presence of metabolic abnormality. No complications were reported. Time to full weight bearing was not dependent on implant choice. However, restricted weight bearing beyond 8 weeks can lead to prolonged healing times. Fixation should be safe, effective and promote early weight bearing and mobilization.

Use of a Suture Anchor Technique to Replace the Tethering Effect of the Ligamentum Teres in the Treatment of Complex Hip Dysplasia.

After open hip reduction in hip dysplasia, some hips can have persistent instability, even after pelvic and femoral osteotomies as well as capsulorrhaphy. While the diseased ligamentum teres in a dislocated hip is thought to contribute to inadequate reduction, the native ligament is thought to provide some level of stability. As such, the purpose of this study was to investigate the utility of a suture augment that replaces the function of the ligamentum teres to provide added stability.
