Metal-on-metal hip resurfacing with uncemented fixation of the femoral component. A minimum 2 year follow up.

The current generation of metal-on-metal hip resurfacing designs has largely been characterized by cemented femoral fixation using a cementless cup. We present the clinical results of 135 entirely uncemented metal-on-metal hip resurfacing procedures. The primary outcome measures were revision for any cause and the Oxford hip score at the latest follow up. The average length of follow up was 2.9 years. The mean Oxford hip score was 18.4 and no patient required revision of either component during the study period. Uncemented femoral fixation may be comparable to fixation with cement in metal-on-metal hip resurfacing.
