The performance of the Cormet hip resurfacing device was evaluated after a minimum of 5 years in 234 hips. The mean age of the patients was 54 years; there were 135 men and 80 women. The primary diagnosis was osteoarthritis in 78% of the patients.

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.

Methods: Single osteochondral grafts, 4.
Osteochondral grafts were transplanted from the trochlea of porcine femurs into drill holes that were 20, 15, and 12 mm in length on the lateral femoral condyle. Grafts initially were pushed in flush with the surrounding cartilage, and then a testing machine pushed the grafts 3 mm deeper. For the 20-, 15-, and 12-mm drill holes, mean forces for pushing the graft flush were 36.
