Clinical Trial Summary

Knee osteoarthritis is a frequent condition whose prevalence is estimated at 7.6% of the French population aged 40 to 75, or approximately 2 million individuals . Viscosupplementation (VS) is a symptomatic treatment of knee osteoarthritis recommended by a large number of learned societies. It consists of the intra-articular injection (IA) of hyaluronic acid (HA), to reduce knee pain by restoring normal joint homeostasis impaired by endogenous HA deficiency.

The IA administration of HA can be performed using 2 protocols: repeated weekly injections (3, sometimes 5 injections) and single injections. To date and there is no argument to favor either protocol. Regardless of the formula used, the safety of HA is excellent (RR of adverse reaction versus saline = 1.01, 95% CI 0.96-1.07, P = 0.6). The indication for viscosupplementation is the symptomatic treatment of mild to moderate knee osteoarthritis after failure and / or intolerance of analgesics or nonsteroidal anti-inflammatory drugs (NSAIDs). In this indication, after HA injection the responder rate is in the order of 70% to 75% at 6 months and approximately 50% at 12 months. However, the predictors of the duration of effectiveness of SV are still unknown. The objective of the study is to research the factors influencing the duration of the effectiveness of SV, under real life conditions.
