PRP injections contain an autologous mixture of platelets and growth factors, which is thought to promote healing and repair in tissues with low healing potential. Currently, most guidelines recommend against the use of PRP as a potential knee OA therapy owing to the lack of high-quality randomized controlled trials and contradictory results.
