Purpose/Introduction To prospectively report the return to sport rate of young athletes undergoing hip arthroscopy with or without periacetabular or distal femoral osteotomy (PAO, DFO) at our institution. To evaluate the relationships between patient characteristics and sport-specific return to sport rate and patient reported outcomes regarding to the ability to return to sport after hip preservation surgery. Methods Prospective evaluation of athletes ages 15 and over with femoroacetabular impingement syndrome (FAI-S) or acetabular dysplasia who elected to undergo hip preservation surgery with intent to return to competitive play post-operatively. All patients underwent hip arthroscopy with or without concomitant PAO or DFO. Patient reported outcomes were obtained using the Hip Outcome Score -Sports Specific Subscale (HOS-SSS) and International Knee Documentation Committee Hip (IKDC-Hip) surveys preoperatively, and the Hip-Return to Sport Index (HIP-RSI), IKDC-Hip, and HOS-SSS questionnaires at 3, 6, and 12 months post-operatively. Patients participated in a standardized post-operative physical therapy program and underwent return to sport performance testing with a physical therapist no sooner than 3 months post-operatively. Results One hundred and two patients were enrolled in the study (73 female). Sixty-nine patients underwent hip arthroscopy alone, twenty-nine had concomitant PAO, and four with concomitant DFO. Mean age was 18.5 ± 3.3 years and mean BMI 20.7 ± 4.4. Post-operative follow-up surveys were obtained at 3 months (n=70), 6 months (n=70), and 1-year (n=48). At 1-year follow-up 38 patients (79%) had returned to sport (79% at same or better performance). Mean HOS-SSS hip scores had statistically significant improvement at 1-year post-op for both groups (86 compared to 49, p< 0.0001). Mean Hip-RSI was 79% at 1-year post-op. 13 of 17 (76%) patients with concomitant PAO or DFO successfully returned to sport, compared to 25 of 30 (83%) who underwent arthroscopy alone. 44 of the 48 patients reported normal or nearly normal function of their hip at 1-year post-op. Sports with the highest return rates were dance, volleyball, and basketball. We did not find statistically significant difference in return to sport rates with regard to age, gender, or BMI. Conclusion The majority of young athletes with FAI-S and hip dysplasia who underwent hip preservation surgery were able to return to competitive play at or above their pre-procedure performance level after return to sport testing. Return to sport rates were similar at one-year in patients undergoing hip arthroscopy with or without concomitant PAO or DFO. Continued follow-up with our cohort will provide more insight.
