15-year follow-up study of total knee arthroplasty in patients with rheumatoid arthritis☆
Section snippets
Materials and methods
From 1981 to 1987, 128 cases of primary total knee arthroplasty with a Kinematic anteriorly joined (AJ) type or posterior cruciate-retention (PCR) were performed in 93 patients with rheumatoid arthritis at our University Hospital and its affiliated hospitals. Cement was used at the insertion of implants. The patella was not resurfaced in any patient at primary surgery except in 3 knees with anterior knee pain and articular deformity in the patellofemoral joint on radiographs.

Clinical evaluation
Knee scores as determined by the HSS score improved from a preoperative mean of 38.6 ± 8.5 points (range, 21–60 points) to 79.3 ± 10.6 points (range, 57–98 points) at the follow-up evaluation (P<.0001, by Wilcoxon signed rank test).
Average KS knee scores improved from a mean of 45.8 ± 13.6 points preoperatively to 88.3 ± 11.2 points at the follow-up evaluation (P<.0001, by Wilcoxon signed rank test). Function as determined by KS score improved from a mean of 11.9 ± 13.6 points preoperatively to
Discussion
In previous reports of TKA in rheumatoid patients, the clinical results were excellent or good in 77% to 81% of patients 6, 7, 11. A prosthesis other than the Kinematic implant was used in these studies. The functional status of rheumatoid patients after TKA remained far below that of patients with osteoarthritis treated with TKA [12]. This was believed to be caused by the polyarticular involvement of rheumatoid arthritis and the steadily declining functional status that can occur in the long

2022, Journal of Orthopaedic ScienceCitation Excerpt :TKA would be more useful if walking function was preserved long term. The cumulative survival rate of TKA prostheses in patients with RA reportedly ranges from 80% to 100% [1–10,21–26]; the main reasons for revision are mechanical loosening, infection, and wear. In this study, the survival rate of TKA implants was 96.6% at 15 years.
