Primary total knee arthroplasty using the Genesis Total Knee Arthroplasty System: 3- to 6-year follow-up study of 105 knees.
This prospective study analyzed data from 105 primary total knee arthroplasties performed in 90 patients using the Genesis Total Knee Arthroplasty System. The 34 men and 56 women with a mean age of 68.7 years (range, 41-86 years) were evaluated at a mean follow-up period of 4.25 years (range, 3-6 years). Fifty-five procedures (52%) used cemented femoral and tibial components, 49 (47%) used cementless femoral and cemented tibial components, and 1 (1%) used cementless femoral and tibial components. The preoperative mean pain and function scores were 50 (range, 12-79) and 41 (range, 5-80), respectively. At the most recent follow-up evaluation, the mean pain score increased to 97 (range, 67-100), and the mean function score increased to 88 (range, 40-100). Mean preoperative range of motion was 104 degrees (range, 50 degrees-130 degrees) and increased to 116 degrees (range, 80 degrees-130 degrees) at most recent follow-up evaluation. Clinically, there were 100 excellent results (95%). 4 good results (4%), and 1 poor result (1%).
