Abstract
Abstract Background Periacetabular osteotomy (PAO) is the gold-standard surgical treatment option for symptomatic developmental dysplasia of the hip. Factors associated with return to sport remain difficult to characterize in an underreported and heterogenous group of patients. Methods Patients undergoing primary Bernese PAO between October 2018 and December 2024 were identified. Patients undergoing PAO who had undergone previous surgery to the ipsilateral hip (i.e., prior PAO or prior failed hip arthroscopy) were excluded. At minimum 10-month follow-up, patients were assessed for return to sport and activity rate, patient-reported hip interference with physical activity, preoperative and postoperative physical activity status, and patient-reported physical functionality. Patients who returned to sport following PAO were compared to those who did not using stepwise multivariable logistic regression. Results A total of 68 active patients undergoing primary PAO were evaluated for return to sport characteristics following their correction. Return to sport in this cohort was 73.5% at a mean time of 8.8±5.7 months. Amongst returners, there was no significant difference in preoperative and postoperative sports engagement frequency (P = 0.357); however, there was a decrease in sports engagement duration (P = 0.005). On stepwise binary logistic regression analysis, psychiatric history was associated with an 86% likelihood reduction in return to sport following PAO (OR = 0.14; 95% confidence interval [CI] = 0.03-0.61; P = 0.012), while preoperative physical activity frequency was positively associated with return to sport (OR = 2.50; 95% CI = 1.52-4.69; P = 0.001). Conclusions Patients report high rates of return and maintenance of physical activity following PAO. Preoperative activity frequency and psychiatric history were predictive of return rates in active patients. Finally, most report a postoperative physical activity level that is congruent with preoperative levels and all factors should be considered during patient counseling for the young adult/athlete.
