Four hundred nineteen knees in 299 patients were examined preoperatively and at two years after polycentric total knee surgery. One hundred forty-three knees were in 109 patients with osteoarthritis. Two hundred seventy-six knees were in 190 patients with rheumatoid arthritis. Pain decreased significantly, use of aids decreased significantly, and distance walked increased significantly in both groups. Rheumatoid patients did not fare as well as osteoarthritics in the use of aids and distance walked. Osteoarthritic knees had proportionately more implant settling, implant loosening and reoperations than did rheumatoid arthritic knees.
对299例患者的419个膝关节在多中心全膝关节置换术前及术后两年进行了检查。109例骨关节炎患者有143个膝关节。190例类风湿关节炎患者有276个膝关节。两组患者的疼痛均显著减轻，辅助工具的使用显著减少，行走距离显著增加。类风湿关节炎患者在辅助工具使用和行走距离方面不如骨关节炎患者。与类风湿关节炎膝关节相比，骨关节炎膝关节出现植入物沉降、植入物松动和再次手术的比例更高。
