title: Primary total knee arthroplasty using the Genesis Total Knee Arthroplasty System: 3- to 6-year follow-up study of 105 knees.
abstract: 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%).
