Pain and functional limitations are important clinical features in knee osteoarthritis. Platelet-rich plasma from autologous blood is being used for symptomatic relief in early knee osteoarthritis. The aim of this study was to assess the efficacy of platelet rich plasma in patients of early knee osteoarthritis. All 50 patients received single intra-articular injection of Platelet Rich Plasma in both knees. Assessment was done by VAS pain scale and WOMAC function score pre injection and 1 week and 3 months post injection. Platelet Rich Plasma showed significant improvement in pain and function at 1 week and 3 months post injection. There was no loss of follow-up. Few patients reported pain for 2 days after the injection which resolved spontaneously. We conclude that Platelet-rich plasma therapy is simple, cheap, feasible and minimally invasive intervention for early knee osteoarthritis. It reduces the analgesic intake and improves the function of knee joint in short term.
