Summary
Concomitant hip arthroscopy and periacetabular osteotomy (PAO) show favorable outcomes. Most studies reported significant improvements in patient-reported outcomes after this combined hip preservation surgery.
Area of Science:
- Orthopedic Surgery
- Hip Preservation Surgery
Background:
- Limited aggregate data exists on outcomes of combined hip arthroscopy and periacetabular osteotomy (PAO).
- Hip dysplasia is a common indication for this combined surgical approach.
Purpose of the Study:
- To systematically review and evaluate the outcomes and survivorship after concomitant hip arthroscopy and PAO.
Main Methods:
- A systematic review of PubMed, Cochrane, and Scopus databases was conducted following PRISMA guidelines.
- Ten studies (Level 3 & 4 evidence) including 553 hips were analyzed for patient characteristics, outcomes, and secondary surgery rates.
- Survivorship was defined as non-conversion to total hip arthroplasty (THA).
Main Results:
- Seven of nine studies reported significant improvements in patient-reported outcomes (PROs) post-surgery.
- Conversion to THA rates were low (<3.4%) across follow-up periods (<5 years and >5 years).
- Overall secondary hip preservation surgery rates were also low (0-10.3%).
Conclusions:
- Concomitant hip arthroscopy and PAO demonstrate favorable patient outcomes.
- The combined procedure shows promising results for hip preservation with low rates of revision surgery or conversion to THA.
