OARSI 2013 is an international expert-consensus guideline on the non-surgical management of primary knee osteoarthritis. A 13-member panel from 10 countries used a systematic review and RAND/UCLA voting to rate 29 treatments as Appropriate, Uncertain, or Not Appropriate. Recommendations are stratified across four clinical sub-phenotypes defined by joint involvement and co-morbidity burden.
When a patient presents with symptomatic knee OA, the first move is conservative: exercise, strength training, weight loss, and education, layered with intra-articular corticosteroids for flares. These six interventions are appropriate for every sub-phenotype and should be exhausted before surgical referral.
The sub-phenotype framework teaches the key decision rule: co-morbidity burden changes drug choice. Oral NSAIDs are reasonable in a healthy patient but become Not Appropriate in someone with prior GI bleed, MI, or renal failure.
This guideline differs from the[unverified citation removed]statement, which called both acetaminophen and intra-articular corticosteroids Inconclusive. OARSI rated corticosteroids Appropriate, so board questions may probe these divergences.
For boards, anchor three facts: the 5% weight-loss threshold, the Not Appropriate rating for glucosamine and chondroitin in disease modification, and the corticosteroid-versus-HA timing tradeoff.
