Purpose:
The clinical impact of periacetabular osteotomy (PAO) in patients with borderline hip dysplasia (BHD) remains unclear. This systematic review aims to evaluate outcomes in patients with BHD undergoing PAO.
Methods:
A systematic review was conducted according to PRISMA guidelines by searching PubMed, Embase, and the Cochrane Library for English-language studies reporting clinical outcomes of PAO in BHD patients. Outcomes assessed included conversion to total hip arthroplasty (THA), return-to-sport (RTS) rates and patient-reported outcome measures (PROMs) such as the modified Harris Hip Score (mHHS), Hip Outcome Score (HOS), Subjective Hip Value (SHV), Hip Disability and Osteoarthritis Outcome Score (HOOS), Short-Form Health Survey (SF-12/SF-36), International Hip Outcome Tool (iHOT-12/iHOT-33) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores.
Results:
Eleven studies (2 Level III, 9 Level IV) with 657 hips met inclusion criteria. The mean patient age was 26.9 years, and follow-up was 48.1 months. The average BMI was 23.3 kg/m², and 13.0% of patients were male. mHHS improved significantly in four studies (mean: 62.6-82.9). SF-12/SF-36 physical scores improved in three studies (37.8-47.6). Two studies each showed gains in iHOT and SHV scores. The reoperation rate was 9.5%, mostly for implant irritation. THA conversion occurred in 0.2%. One study reported a 92.5% return-to-sport rate, typically within 6 months.
Conclusion:
In patients with BHD undergoing PAO, there is consistent improvement in most PROMs along with a low rate of reoperation and conversion to THA.
Level Of Evidence:
Level IV, systematic review of Level III-IV studies.
