Summary:From 1978 to 1991, 82 cementless total knee replacements (Mark II or M/G) were performed in 61 rheumatoid arthritis (RA) patients in our clinic. Of these, we were able to follow 48 joints in 33 patients for more than one year. Clinical results were evaluated using the J. O. A. criteria of RA knee. At the end of the follow-up peried, the mean knee score had improved from 42.5 points preoperatively to 66.4 points postoperatively. The incidence of postoperative complications was 15 percent. Three revisions had been required, two for loose knee and one for posterior dislocation of the tibia. Factors which influenced postoperative clinical results were preoperative Class type and period of postoperative observation.
