Effectiveness of Platelet-rich Plasma Treatment of Knee Osteoarthritis

Summary

Osteoarthritis (OA) is a disease that affects the joints of the body, causing pain, stiffness, and reduced mobility. To treat knee OA, a therapy called platelet-rich plasma (PRP) is used, which involves making a concentrated substance from the patient's own blood and injecting it into the joint. It has been shown that this therapy is effective in reducing pain; however, more research is needed to optimize the preparation and identify which patients are more receptive to the treatment. The primary objective of this study is to evaluate two modalities of PRP application and determine whether these treatments result in better pain reduction and improved functionality. The secondary objective is to explore the association between changes in LEFS questionnaire scores and/or maximal quadriceps isometric strength and possible clinical improvement.
