The Bernese periacetabular osteotomy effectively relieves hip pain and improves function for acetabular dysplasia. However, current evidence is mainly Level IV, highlighting the need for higher-quality studies on this surgical intervention.
Area of Science:
- Orthopedic surgery
- Hip reconstruction
- Evidence-based medicine
Background:
- Symptomatic acetabular dysplasia is often treated with Bernese periacetabular osteotomy.
- The clinical evidence supporting its efficacy for pain relief and functional improvement requires further definition.
Purpose of the Study:
- To systematically review the literature on Bernese periacetabular osteotomy.
- To assess the level of evidence, radiographic correction, clinical outcomes, and complications associated with the procedure.
Main Methods:
- Systematic literature review including 13 studies.
- Analysis of study levels of evidence (predominantly Level IV).
- Evaluation of radiographic deformity correction, functional outcomes, and complication rates.
Main Results:
- Consistent radiographic deformity correction and improved hip function were observed across studies.
- Clinical failures were linked to severe preoperative osteoarthritis; total hip arthroplasty conversion ranged from 0% to 17%.
- Major complications occurred in 6% to 37% of procedures.
Conclusions:
- Bernese periacetabular osteotomy offers short- to midterm pain relief and functional improvement for most patients.
- The current evidence base for this procedure is predominantly Level IV, indicating a need for more rigorous research.
