How Do PRP Joint Injections Treat Osteoarthritis?
The goal of PRP joint injections for the treatment of osteoarthritis is to reduce pain, improve joint function and to ultimately slow, halt or even repair the damaged joint cartilage.
To prepare for a blood plasma treatment, platelet rich plasma is extracted from a patient’s own blood. The treatment begins by removing a vial of blood, typically 30 milliliters. The blood is then spun in a centrifuge, a machine that uses high speeds to separate the four main components of the blood. Once the components are separated, the platelet rich plasma is removed. The plasma is then injected into the injured joint releasing three to five times the growth factors compared to normal human blood. These growth factors recruit and increase the proliferation of reparative cells. In some cases, an “activating agent”, which is either thrombin or calcium chloride may also be added into the injection.
The entire process takes less than 15 minutes. Most patients will require 1-3 sets of PRP injections. Each set of treatments is spaced 4-6 weeks apart. Response to treatment will vary with each patient. As PRP is obtained from the patient’s own blood, the risk of reaction is low. As with any injection, there is a small risk of injury to any structures in the area as well as a very small risk of infection.
