Results of 89 polycentric knee arthroplasties are assessed from 2 years to 7 1/2 years after operation. Seventy-two arthroplasties (81%) are considered to improve the mobility of the patient, with 17 arthroplasties producing no improvement. Infection after operation in 6 arthroplasties (7%) required arthrodesis of 3 arthroplasties. Loosening of prosthetic components occurred in 9 arthroplasties (10%).
