Abstract
Nine arthroplasties in which the cemented kinematic-stabilizer total knee prosthesis was used for severe varus and valgus deformity of the rheumatoid knee were reviewed. There were two varus and seven valgus knees which should be recommended using the hinge-type prosthesis.None of the patients could walk before operation, but all of them came out to be able to walk with or without canes. The average femorotibial angle was 174 degrees at the final follow-up.We prefer using the semi-constrained type prosthesis with soft tissue release, bone graft and postoperative orthosis for severely deformed knee to the hinge-type prosthesis which needs more bone resection.
