Hip Resurfacing a suitable option for those with mild DDH (Crowe I and II)

A recent systematic review and meta-analysis evaluated the outcomes of hip resurfacing arthroplasty (HRA) in patients with mild developmental dysplasia of the hip (DDH; Crowe I/II). The review screened 65 articles, with 11 met inclusion criteria, totalling 895 patients and 1,006 hips with DDH, with a mean follow-up of 7.1 years. 

Key Findings:

·        Pooled survivorship was 93% and complications occurred in 13% of cases.

·        No statistically significant difference in revision risk when comparing HRA in DDH vs HRA in primary osteoarthritis (OA), or HRA in DDH vs total hip arthroplasty (THA) in DDH.

·        Patients treated with HRA for DDH achieved significantly greater postoperative hip flexion compared with THA in DDH.

JM Comments:

This review supports the selective use of hip resurfacing arthroplasty (HRA) in Crowe I–II DDH patients, especially when modern surgical techniques and DDH-specific implants are applied, highlighting HRA’s emerging role as a versatile treatment option for a broader patient population than traditionally considered.
