Total hip and knee arthroplasty for juvenile rheumatoid arthritis.
We performed 23 total hip and knee arthroplasties (15 total hip and 8 total knee arthroplasties) in 18 children with juvenile rheumatoid arthritis between 1984 and 2001. The mean age at surgery was 17.8 years (range 13 to 24 years). The age of presentation of the disease was from 4 to 10 years with average 7.3 years. The average length of follow-up was 9.7 years (range 7 to 16 years). All patients conformed with the American Rheumatism Association criteria for juvenile rheumatoid arthritis. All patients had complete loss of joint space and various combination of subchondral sclerosis, flattening of the femoral head, anterior inclination of the neck. Three knees were diagnosed with bony ankylosis. Follow-up was based on the Merle d'Aubigne et Postel scale modified by Charnley. One acetabular component has been revised to date. No femoral or tibial components have been revised. No patient had pain post-operatively and function was very satisfactory. Total hip and knee arthroplasties are technically difficult to execute in this age and should be performed in specialized centers. With appropriate indications pain relief,decrease of deformity and improvement of quality of life can be achieved in most patients.
