RN Poll: Intra-articular Injections for Knee OA

Intra-articular steroids relieve the pain of knee OA, but have long-term risks. Hyaluronic acid injections appear innocuous, but their efficacy is highly controversial. (The ACR recommends them "conditionally" for certain patients who can't be helped by NSAIDs, but the AAOS has found that they do not "meet the minimum clinically important improvement thresholds," as the chair of its guidelines oversight committee observed.)
