Platelet rich plasma is an ultr-filterate of autologus (patients' own) blood which is rich in growth factors and inflammatory components. Mainly, its uses have been implicated in partial thickness tears and sprains in atheletes.

PRP is basically seperated from patients blood by a process called ultra-centrifugation and takes a while for the layer to get isolated. The PRP should be maintained in a cold chain while storage and needs wise patient selection for prognosticating results. Patient should understand that since PRP has growth factors and inflammatory mediators, it increases pain for the first 3 days of injection. The pain and inflammation settles down gradually with healing of the fibrous tissue.

There is a documented role of Platelet rich plasma in recalcitrant tennis elbow, Planter Fasciitis, Ankle sprain, rotator cuff tendinosis and early osteo-arthritis of the knee also. Detailed patient councelling before procedure, clearly stating pros and cons should be done. Analgesic and anti-inflammtory medications should be stopped with initiation of treatment.
