Purpose: We conducted a retrospective study of the mid-term results of cementless TKA inthcumatoid arthritis (RA) patients.Method: The subject of the study was 61 knees of 52 RA patients treated by cementless TKA over a 5-year period. We assessed changes in ADL after surgery baseed on the JOA (Japan Orthopedics Association) knee score and performed a radiological analysis by the method of the Knee Society.Result: Two patients developed in fection and required replacement of the prosthesis. The overall survival rate was 96.7%. The average JOA score was 94.17 postoperatively as opposed to 53.85 preoperatively, showing a mean improvement in ADL. There were no major radiolucent signs or evidence of loosening radiologically even at 5 years. No revisions of TKA were required because of loosening or sin king.Conclusion: The mid-term results of cementless TKA in RA patients were good in terms of ADL, even thogh sinking or loosening occurred in some patients.
