Patients with inflammatory arthritis who underwent total hip arthroplasty experienced higher rates of complications compared with patients who had osteoarthritis, according to results.

Researchers compared the prevalence of in-hospital medical and orthopedic complications between patients with inflammatory arthritis and osteoarthritis (OA) who underwent total hip arthroplasty (THA) between 2002 and 2011.

Results showed patients with rheumatoid arthritis, juvenile idiopathic arthritis, systemic lupus erythematosus and ankylosing spondylitis experienced significantly more inpatient medical and orthopedic complications immediately after THA compared with patients with OA. The highest orthopedic complication rate of 2.8% was found among patients with juvenile idiopathic arthritis, researchers noted. Researchers also found a significant increase in wound dehiscence among patients with rheumatoid arthritis and ankylosing spondylitis, significantly more periprosthetic fractures among patients with juvenile idiopathic arthritis and increased mortality for patients with systemic lupus erythematosus. However, patients with psoriatic arthritis had no significant differences in medical or orthopedic complications compared with patients with OA. – by Casey Tingle
