title: Metal-on-metal hip resurfacing in patients aged 65 or older.
abstract: There is little information regarding the clinical performance of hip resurfacing arthroplasty (HRA) in older patients. Eighty-seven patients (99 hips) aged 65 years or older received HRA while a control group of 52 patients (64 hips) received a primary THA. The average age was 69.2 years for the HRA group and 71.9 years for the THA group. Follow-up ranged from 2 to 13 years. UCLA walking, function and activity scores and SF-12 scores were higher in the HRA group. At 10 years, the Kaplan-Meier overall survivorship rates were 96.7% for the HRA group and 91.2% for the THA group (p = 0.3174). We suggest considering hip resurfacing for patients 65 or older in centres where there is expertise in performing this procedure.
