Poster 178: Outcomes of SLAP Repair vs. Biceps Tenodesis of SLAP Lesions in Females: A Retrospective Review

Objectives: When surgically managing superior labrum from anterior to posterior (SLAP) tears, there is no consensus on whether SLAP repair or biceps tenodesis yields superior long term outcomes. Additionally, no previous studies have specifically examined outcomes of these procedures in female patients, despite evidence of sex-based differences in recovery following orthopedic surgery. The purpose of this study was to retrospectively compare outcomes after SLAP repair and biceps tenodesis in females. Prior to the start of the study, it was predicted that outcomes between patients who undergo SLAP repair and biceps tenodesis as a treatment will not significantly differ. Methods: Female patients who underwent arthroscopic SLAP repair or biceps tenodesis for treatment of an SLAP lesion between 1/1/2014 and 9/1/2019 at a single institution were retrospectively reviewed. Patients were queried using CPT codes for arthroscopic SLAP repair or biceps tenodesis: for those identified, electronic medical records were reviewed to confirm they met inclusion criteria. Exclusion criteria included: age less than 18 years old at the time of surgery, revision surgery, and concomitant rotator cuff repair at the time of surgery. Patients were contacted at a minimum of two-years post- surgery and asked to complete the standardized American Shoulder and Elbow Surgeons (ASES) score, single assessment numerical evaluation (SANE) survey, and visual analog scale (VAS) for pain. Patients were also given a custom survey assessing return to activity and level of activity following the operation. Patient demographics collected included age at time of surgery, BMI, laterality, and procedure type. Differences in post-operative function between the procedures were assessed using T-tests or Mann- Whitney U tests for numerical data and Chi-Square testing for categorical data. Results: The study included 118 patients. 61 (51.7%) underwent arthroscopic SLAP repair, and 57 (48.3%) underwent open or arthroscopic biceps tenodesis. Comparing demographic data for SLAP repair versus biceps tenodesis groups, mean age was 35.2±8.93 years versus 45.5±10.2 years (p
