Abstract
Developmental dysplasia of the hip (DDH) is the most common orthopedic condition with a global incidence of 1% to 3%. (1) Secondary to increased screening methods and improved diagnostic modalities, [...]
Background: Periacetabular osteotomy (PAO) has been used as a treatment modality for development dysplasia of the hip (DDH). Many patients will progress to total hip arthroplasty (THA) following PAO. There is a discrepancy in the literature regarding outcomes of THA after PAO. Methods: A retrospective study was performed. Ten patients (12 hips) with prior PAO who progressed to THA with at least 1-year follow-up after THA were identified. A control group of patients matched for age, sex, and body mass index (BMI) who underwent primary THA with minimum of 1-year follow-up were included. Demographic and radiographic parameters as well as clinical outcomes using the modified Harris Hip Score (mHHS) were collected. Results: The mean age at the time of THA was 36.2 [+ or -] 9.7 years for the PAO and 37.8 [+ or -] 9.1 years for the control cohorts. There was no difference in the demographics between the groups. At mean follow-up time of 22.8 [+ or -] 10.7 months for the PAO group and 25 [+ or -] 13.8 months for the control group, there was no significant difference in mHHS following THA. There was significant improvement in mHHS from preoperative to postoperative levels (p < 0.01). Conclusion: Total hip arthroplasty is an effective means to restore quality of life and function in patients who develop osteoarthritis following PAO, with equivalent outcomes to those undergoing primary THA.
