Total knee arthroplasty in Paget's disease: technical problems and results

Eleven total knee arthroplasties performed in 10 patients with Paget's disease were reviewed at 2 to 16 years postoperatively. Cemented total knee arthroplasties were performed in all cases. Range of motion improved by 21 degrees postoperatively and the follow-up Knee Society score averaged 83 points. One knee was rated poor with a score <70 points; this knee was the only knee with a loose component. All components resting on pagetic bone had a solid interface on radiographic review at an average of 5.7 years postoperatively. Although technical difficulties are encountered in achieving correct alignment and exposing the knee with local Paget's disease, good long-term outcome can be achieved.
