Summary
Chiari pelvic osteotomy (CPO) can yield satisfactory results in selected younger patients with hip osteoarthritis, even with advanced disease. This joint-conserving procedure may delay the need for total hip arthroplasty (THA).
Area of Science:
- Orthopedic surgery
- Hip joint preservation
- Osteoarthritis treatment
Background:
- Chiari pelvic osteotomy (CPO) indications have narrowed, with decreased surgical frequency.
- Published long-term data suggest CPO can achieve satisfactory functional outcomes in select patients.
- Investigating factors influencing CPO survival and conversion to total hip arthroplasty (THA) is crucial.
Purpose of the Study:
- To identify parameters affecting the long-term survival of Chiari pelvic osteotomy (CPO).
- To analyze factors influencing the conversion rate of CPO to total hip arthroplasty (THA).
Main Methods:
- Single-center retrospective case-series study.
- Included 172 CPO procedures in 158 patients (1976-2012).
- Final analysis included 115 patients (124 CPO) with a median follow-up of 19 years.
Main Results:
- 51 total hip arthroplasties (THA) were performed in 49 patients out of 124 CPO procedures.
- The median time from CPO to THA was 14 years.
Conclusions:
- CPO remains a viable joint-preserving option for younger patients with advanced hip osteoarthritis.
- Patients should be selected carefully, understanding the potential for a less optimal outcome compared to primary THA.
- CPO may serve as a valuable procedure to delay THA in appropriate candidates.
