Abstract:
We report the early results of 10 consecutive metal-on-metal resurfacing arthroplasties performed between May 2006 and July 2007 in young, active patients with gross femoral head defects. Failure was classified as revision for any reason. The mean age of our cohort at the time of surgery was 42.8 years and the minimal period of follow-up was 6.9 months. No patients were lost to follow-up. Up to the time of last review, there were no failures and all patients have returned to their preoperative levels of activity. This study shows promising early results of a bone-conserving, hydroxyapatite-coated, uncemented metal-on-metal bearing prosthesis in young, active patients with bony defects of the femoral head.
