- In 2013, the American Academy of Orthopaedic Surgeons (AAOS) clinical practice guideline (CPG) on the treatment of knee osteoarthritis (OA) made a strong recommendation not in favor of the use of intraarticular hyaluronic acid (IAHA) because the improvement in pain, although statistically significant, did not meet the threshold for a minimal clinically important difference.
- The AAOS CPG, and subsequent publications, suggest there may be clinically important differences in the effectiveness of high versus low molecular weight (MW) IAHA.
- Given further research published since the CPG, we aimed to examine this issue by performing a network meta-analysis (NMA) on an updated literature search of both direct and indirect evidence.
