Hyaluronic Acid Injections for Shoulder Conditions

Direct Recommendation

• The American Academy of Orthopaedic Surgeons provides a Grade C recommendation (Level IV evidence) that injectable viscosupplementation is an option for treating glenohumeral osteoarthritis 1
• Hyaluronic acid injections are strongly recommended against for hip osteoarthritis due to high-quality evidence showing no benefit 2, 3

Evidence-Based Treatment Algorithm for Shoulder Conditions

• The American Academy of Orthopaedic Surgeons guideline is based on limited evidence, with only one industry-supported Level IV study meeting inclusion criteria for the AAOS guideline 1
• Meta-analyses of low risk-of-bias trials show effect sizes approaching zero for hyaluronic acid injections compared to saline for knee and hip OA 2, 3

Common Pitfalls to Avoid

• The American College of Rheumatology strongly recommends against hyaluronic acid injections for knee OA based on rigorous meta-analyses, but shoulder evidence is separate and more limited 2, 3, 1
• The American Academy of Orthopaedic Surgeons recommends against delaying definitive treatment for severe glenohumeral OA, with arthroplasty (TSA preferred over hemiarthroplasty) remaining the definitive treatment with Grade B evidence 1
