Summary
Periacetabular osteotomy with concomitant hip arthroscopy for symptomatic hip dysplasia resulted in significant improvements in functional outcomes.
Abstract
Purpose
Periacetabular osteotomy (PAO) concomitant with hip arthroscopy used as treatment for symptomatic hip acetabular dysplasia has shown favorable outcomes at mid-term follow-up. The purpose of the current study is to examine return-to-sport (RTS) rates at mid-term follow-up.
Methods
Retrospectively analyzed data for all patients who underwent periacetabular osteotomy concomitant with hip arthroscopy as treatment for painful hip dysplasia between November 2010 and December 2018. Included patients reported sports participation and had completed preoperatory and minimum of 5-year postoperative questionnaires for at least one of the following patient-reported outcomes (PROs): the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12),Visual Analogue Scale (VAS), or documented an endpoint during the study timeframe. Clinically important thresholds were included in the analysis. An overall return-to-sport analysis was conducted, and continuation of sport was analyzed at minimum of 5 years postoperative.
Results
28 patients (29 hips) were included. Patients experienced significant improvement in all PROs. Furthermore, a high percentage of patients reached the MCID and PASS. Of the 28 patients, 3 (10.8%) chose to stop sport participation due to lifestyle transitions. Among the remaining 25 patients, 18 (72%) returned to sports at any time postoperatively. Three patients (12%) did not return due to hip symptoms. Of the 18 patients who returned at any timepoint, 14 (77.8%) continued to practice sports at a minimum of 5 years postoperative. Three hips (10.8%) required revision hip arthroscopy, and two (7.1%) underwent conversion to THA.
Conclusion
PAO with concomitant hip arthroscopy for symptomatic hip dysplasia resulted in significant improvements in functional outcomes, with a high percentage of patients achieving important clinical thresholds. There was a high rate of return to sports, enabling a substantial number of patients to continue practicing at a minimum 5-year follow-up.
