Between 1979 and 1989, 42 patients (63 knees) suffering from rheumatoid arthritis received total knee replacements in our department. 15 patients did not return for follow-up examinations, including 5 who died during the follow-up period. The remaining 27 patients (41 knees) were followed for an average of 4.7 years. The clinical results were evaluated using the criteria of three universities proposal.
By the end of the follow-up period, the mean knee score had improved from 34.2 points preoperatively to 60.0 points postoperatively. The incidence of postoperative complications, including loosening, patellar dislocation, infection and femoral fracture, was 24 percent. Revision surgery was necessitated by loosening (2 knees) and patellar dislocation (1 knee). In our study, the prognosis was affected markedly by the complications.
