Cementless femoral components in young patients: review and meta-analysis of total hip arthroplasty and hip resurfacing

Historically, there have always been perceived advantages to hip resurfacing rather than total hip arthroplasty. However, as newer generation hip arthroplasties with improved design have emerged, these previously established failure rate comparisons may no longer be valid. The current study used a meta-analysis to analyze current evidence on this subject. Findings revealed that pooled mechanical failure rates of the femoral component were lower in total hip arthroplasty when compared to the resurfacing, although these rates were low for both procedures. Acetabular and overall failure rates were lower with hip resurfacing.
