One-Year Function Similar After Resurfacing Hip Arthroplasty or Total Hip Arthroplasty

Resurfacing hip arthroplasty (in which the femoral head is resurfaced with a cap and the neck is preserved) is an increasingly popular alternative to total hip arthroplasty (in which the femoral head and neck are replaced). Resurfacing may be especially attractive for young patients because it results in more hip movement than total hip arthroplasty and may make revision surgery easier later in the patient's life. In this single-center, assessor-blinded, trial, U.K. investigators randomized 126 adults with severe hip arthritis to total hip arthroplasty or to resurfacing hip arthroplasty.

Intention-to-treat analysis showed no between-group difference in hip function and activity levels at 12 months. Overall complication rates did not differ b…
