Athletes Undergoing Concomitant Hip Arthroscopy and Periacetabular Osteotomy Demonstrate Greater Than 80% Return-to-Sport Rate at 2-Year Minimum Follow-Up

Purpose: To report minimum 2-year follow-up patient-reported outcomes and return-to-sport (RTS) rates in athletes undergoing concomitant hip arthroscopy and periacetabular osteotomy (PAO) to treat acetabular dysplasia and intra-articular pathologies such as cam deformity and labral tears. Methods: We reviewed the data of consecutive athletes undergoing concomitant primary hip arthroscopy and PAO for acetabular dysplasia and cam deformity from November 2010 to December 2018. Patients were included in the study if they had the following preoperative and minimum 2-year postoperative scores: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and Hip Outcome Score-Sport-Specific Subscale (HOS-SSS). The percentage of patients who achieved the minimal clinically important difference was recorded, in addition to RTS status. Results: A total of 29 athletes (29 hips) were included, with a mean follow-up time of 34.1 +/- 7.9 months, mean age of 26.0 +/- 8.7 years, and mean body mass index of 23.7 +/- 3.4. These athletes showed significant improvements in the mHHS, NAHS, and HO SS S S from baseline to latest follow-up (P < .001). The minimal clinically important difference was achieved at high rates for the mHHS (82.8%), NAHS (86.2%), and HOS-SSS (79.3%). Athletes who attempted to RTS successfully returned at a rate of 81.8%. Conclusions: Athletes undergoing concomitant hip arthroscopy and PAO showed significant improvements in patient-reported outcomes at minimum 2-year follow-up and had an RTS rate of 81.8%.
