The purpose of this prospective randomized study was to compare the 2-year follow-up penetration of Oxinium versus Metal on polyethylene in a consecutive series of low friction total hip arthroplasty. Between July 2006 and May 2006, 50 patients (27 females and 23 males) with a mean age of 60.6 ± 11.4 years (21 to 75) were randomized to receive either Oxinium (25 hips) or Metal (25 hips) femoral head. Other parameters, including the femoral component and the all polyethylene socket (EtO sterilized), were identical in both groups. The primary criterion for evaluation was linear head penetration measurement using the Martell system.Introduction
