Abstract
Three RA patients with severe valgus deformity were treated with total knee arthroplasty. Two patients were treated with posterior stabilized TKA and one was treated with constrained TKA. Clinical data were summarized using the scoring system of the Japanese Orthopaedic Association (JOA score). The femoro-tibial angle (FTA) averaged 155.7° (range, 155°-156°) preoperatively and 174.7° (range, 169°-179°) postoperatively. JOA score was 29 (range, 16-43) preoperatively and 73 (range, 58-93) postoperatively. There were two complications in the group related to superficial wound problems. All patients were satisfied with the operation.
