Platelet-Rich Plasma (PRP) Injections


Platelet-Rich Plasma (PRP) injection is a procedure in which a sample of your blood is used to extract and concentrate your own growth factors, which are then injected back into your body part that is injured.  PRP injections are becoming increasingly popular because of their effectiveness in treating various sports injuries and osteoarthritis and because they are viewed as a very “natural” treatment that is derived from your own blood, and does not involve the injection of any medication. Every year, more and more research studies have been completed and have increasingly shown the effectiveness of PRP.


The growth factors in the PRP injection work to promote healing of the injured body part by helping your body to produce “collagen” which is a building block for musculoskeletal tissue such as bone, tendons, ligaments and cartilage.  They also promote the growth and development of the actual cells that make up this musculoskeletal tissue, thereby helping with the healing process.  These growth factors also stimulate new blood vessel formation and help in the development of ‘’stem cells” which form the basis of new tissue growth.


Some common conditions in sports medicine that are treated with PRP include:

  • Tendonitis, tendinopathies (e.g., “Tennis elbow”, patellar tendonitis, plantar fasciitis, Achilles tendonitis, rotator cuff injuries, etc.)
  • Osteoarthritis of the knee and other joints
  • Articular cartilage injuries
  • Other tendon, muscle and ligament injuries


If you are interested in looking into PRP injections further, please ask your family physician for a referral to GRSM.  Your injury will be assessed by a GRSM sports medicine physician.  Treatment, including PRP and non-PRP options, will be discussed comprehensively so that you can decide on an appropriate management plan.


If you decide to proceed with a PRP injection, the cost of this procedure is not covered under OHIP and must be paid out-of-pocket or by a third party payer such as an insurance plan.
