OSTEOARTHRITIS Joint Replacement Complications More Frequent in RA Than OA
Patients with rheumatoid arthritis (RA) have more complications after total joint arthroplasty (TJA) than patients with osteoarthritis (OA) and are at notably higher risk for dislocation of replaced hip joints, according to data from a systematic review and meta-analysis published online November 28 and in the December issue of Arthritis & Rheumatism.

Researchers’ key findings were that compared with patients with OA, patients with RA had increased risk for dislocation after total hip replacement and increased risk for infection after total knee replacement, but did not have higher revision rates, 90-day mortality rates, or venous thromboembolic events following either joint replacement procedure.

Hip Dislocation Risk a Surprise

The researchers found that patients with RA had double the risk for hip dislocation after total hip arthroplasty compared with patients with OA. The increased risk for dislocation after total hip arthroplasty in patients with RA was a surprise and might be in part a result of greater soft tissue damage or poorer hip abductor strength in patients with RA vs patients with OA.
