OARSI Guidelines for the Non-Surgical Management of Knee Osteoarthritis.

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.

Key Findings

Six modalities were rated Appropriate for every knee OA patient:
- Land-based exercise
- Water-based exercise
- Strength training
- Weight management
- Self-management and education
- Biomechanical interventions
- Plus intra-articular corticosteroids. These form the backbone of any conservative algorithm before surgical referral.
Land-based exercise produced small but clinically relevant benefits, with pain SMD ranging from 0.34 to 0.63 and t'ai chi scoring at the high end. This is why supervised exercise, not rest, is first-line for symptomatic knee OA.
Weight loss is dose-dependent: a 5% reduction over 20 weeks (0.25% per week) was the threshold for efficacy in overweight patients. Below this target the intervention loses measurable benefit.
Intra-articular corticosteroids beat hyaluronic acid for pain at 2 weeks, but HA provided greater benefit at 12 and 26 weeks. Choose the injectable based on whether the patient needs fast or durable relief.
Oral NSAID appropriateness falls as co-morbidity rises:
- No co-morbidity: Appropriate
- Moderate risk: Uncertain
- High risk: Not Appropriate
- In high-risk patients the panel strongly advised against oral NSAIDs entirely and recommended PPI co-prescription when they must be used.
Glucosamine and chondroitin were rated Uncertain for symptoms and Not Appropriate for disease modification, reflecting null results in large high-quality trials like GAIT.
Opioids carried a 4-fold risk of withdrawal for adverse events (RR 4.05) and over 3-fold risk of serious adverse events (RR 3.35), earning only an Uncertain rating despite modest analgesia.
Risedronate and neuromuscular electrical stimulation were the only treatments voted Not Appropriate outright across all sub-phenotypes.

Board PearlOARSI 2013 makes exercise, weight loss, strength training, self-management, biomechanical interventions, and intra-articular corticosteroids appropriate for all knee OA patients.
