Impact of Total Hip Resurfacing Arthroplasty on Health-Related Quality of Life Measures: A Systematic Review and Meta-Analysis

The aim of this study was to investigate the effect of total hip resurfacing arthroplasty (RA) on general health-related quality of life (HRQOL) and disease/hip-specific measures. Original studies published after 2000, enrolling at least ten skeletally mature patients with a minimum follow-up of 6 months were considered. The standardized mean difference (SMD) was obtained with a random effects model. The cumulative patient population encompassed 1898 patients (2123 RA). Mean follow-up duration was 4 years. The physical component score (P<0.001) and mental component score (P=0.05) of SF-12, and the EuroQol-5D (P<0.0001) improved significantly. WOMAC global score and the subscales (P<0.00001) were also improved. Harris Hip Score (P<0.00001), Oxford Hip Score (P<0.001) and UCLA (P<0.00001) were markedly improved and patient satisfaction was favorable.
