Abstract
We reviewed the short-term results of total knee arthroplasty (TKA) with the Genesis II total knee system after a mean foi!ow-up period of 3 years 9 months. The subjects were 33 patients (40 knees) with OA and 12 patients (12 knees) with RA. There were 9 men and 36 women, and their mean age at the time of surgery was 71.O years. A mobile CR (postevior cruciate retention design), fixed CR, and mobile PS (postevior stabilizer design) were used in 22 knees, 6 knees, and 19 knees, respectively. Patellar resurfacing was performed in 12 knees (23.1%), and lateral release was performed in 10 knees (19.2%). No subluxation of the patella was observed postoperatively. Although the mean angle of the components was generally satisfactory, the mean angle of the femoral component was variable, and a notch formed in 21.2%. Complications reported consis backward dislocation in 1 patient (1 knee), heterotopic ossification in 1 patient (2 knees), and supracondylar femoral fracture in 1 patient (1 knee). The JOA scores improved. No radiolucent line or loosening were observed, and the results were satisfactory.
