Total hip arthroplasty using porous-coated femoral components in patients with rheumatoid arthritis

We studied the results of total hip arthroplasty (THA) using AML porous-coa ted femoral components at a mean follow-up of 11 years in a non-selected, c onsecutive series of patients with rheumatoid arthritis. We reviewed 64 pat ients with 82 primary THAs using these components. There were seven men (8 hips) and 57 women (74 hips) with a mean age of 55.1 years (24 to 80) at th e time of surgery. Nine patients (11 hips) died before the two-year follow-up. Of the remainin g 71 hips, only one stem was revised for aseptic loosening, Survivorship fo r the stems was 98.1% (95% confidence interval (CI) 94.5 to 100.0) at ten y ears, using a life-table analysis, with revision for any reason as an endpo int, Of the 70 unrevised stems, 66 (94%) had bony ingrowth, while four (6%) were radiologically loose at the most recent follow-up (mean 11.4 years), Our study shows the excellent long-term results which can be achieved with porous-coated femoral components in patients with rheumatoid arthritis.
