Early morbidity after total hip replacement - Rheumatoid arthritis versus osteoarthritis

The authors used the California Health Facilities Discharge data for 1984 and 1985 to compare retrospectively in-hospital morbidity and mortality of all 721 patients with rheumatoid arthritis versus all 8,859 patients with osteoarthritis who underwent a non-emergent, first-time, unilateral total hip arthroplasty. The lengths of hospitalization, in-hospital mortality rates, and incidences of post-operative complications were similar in the two groups except for higher rates of wound infection and wound dehiscence in the patients with rheumatoid arthritis and a higher rate of thromboembolic events in the osteoarthritis group. The short-term outcome of patients with rheumatoid arthritis appears comparable to that of patients with osteoarthritis.
