Brief Summary

The French Society of Rheumatology cannot rule on the value of intra-articular injections of PRP due to the lack of hindsight and insufficient data. In fact, the injection protocols are very heterogeneous in terms of preparation method, the presence or not of leukocytes, the number of centrifugations, the volume injected, the ultrasound guidance, which makes it difficult to analyze the literature. The investigator objective is therefore to evaluate the effectiveness of combined injections of PRP and hyaluronic acid.
