The Follow-up Study of Total Hip Replacement for Rheumatoid Arthritis

The results of 33 total hip arthroplasties in 27 rheumatoid arthritic patients were reviewed one to 5 years (mean, 3.5 years) after operation. We evaluated radiographic analysis of them. The incidence of clear zone was 82% (27 joints), and progression of central migration was revealed in 3 joints (9%). Bone transplantation and mesh implant in the acetabular base were effective in the cases with protrusio acetabuli and thinning of acetabular base.
