Primary total knee arthroplasty using the Genesis I total knee prosthesis: a 5- to 10-year follow-up study.

This study analyzed the data from 82 primary total knee arthroplasties performed in 74 patients using the Genesis Total Knee Arthroplasty System. Ten men and 64 women with a mean age of 78 years were evaluated at a mean follow-up of 7 years. Seventy procedures used cemented femoral and tibial components, and 12 used cementless femoral and tibial components. The preoperative mean HSS score was 39. At the most recent follow-up, the mean HSS score increased to 92. The mean preoperative range of motion was 82 degrees and increased to 108 at the most recent follow-up. Clinically, there were 63 excellent (77%), 14 good (17%), 4 fair (5%), and 1 poor (1%) result.
