Knee arthritis is a very common problem for patients worldwide. With the aging of the population this will become one of the most important medical issues to address with biologic therapies.
Conflicting results have recently been published about the use of platelet rich plasma in the treatment of knee arthritis. Filardo, Kon et al found no significant differences between PRP and hyaluronic acid injections. (see full abstract). Conversely, Cerza et al did find significantly better clinical outcomes when patients were treated with PRP vs hyaluronic acid injections. (see full abstract) The version of PRP used in these two studies were different. The first study also used three injections and the second four weekly injections. Clearly, more research is needed to clarify the value of PRP for knee arthritis and determine the optimal formulations and techniques.
