Comparison of Acetaminophen and PRP Therapy for Knee OA

Summary

The purpose of this study is to test whether the platelet-rich plasma (PRP) intra-articular injection therapy is effective as an alternative treatment option in patients with mild knee osteoarthritis within a controlled randomized study compared to first line treatment acetaminophen. The investigators will evaluate patients outcome in level of pain, knee function and quality of life before the treatment and at 6, 12 and 24 weeks follow up. The study will be complemented with in vitro experiments of human osteoarthritic cartilage explants culture (treated with PRP) for histological and gene expression assays. PRP intra-articular injections therapy is effective in patients with mild knee osteoarthritis by modifying the biochemical joint environment and cartilage regeneration capability.
