Platelet Rich Plasma

Platelet Rich Plasma (PRP) is a non-operative procedure, where platelets from the patient’s blood are injected into cartilage and tendons to reduce pain and aid in the healing of common injuries.

Platelet-Rich Plasma is another widely used, non-invasive procedure similar to stem cell therapy. While stem cells are more commonly used in joints that need tissue regeneration, PRP focuses on areas that need the normal healing mechanisms restored. The ROM Clinic will always carefully evaluate each situation individually to decide which procedure is best to treat your condition.

What is Platelet Rich Plasma?


Platelet Rich Plasma (PRP) therapy is a non-surgical procedure that attempts to accelerate the healing process of soft tissue in patients suffering from tendon injuries, such as tennis elbow, or osteoarthritis. PRP injections can be an alternative to surgery and cortisone shots.

The injections are comprised of the patient’s own platelets, which release growth factors capable of recruiting reparative cells. The concentration of platelets is significantly increased in PRP as compared to regular plasma. Platelets naturally attract to damaged tissue areas in the body. Injecting these platelets into damaged ligaments, tendons, and joints stimulates the natural repair process.

The Procedure


PRP is obtained by first drawing blood from the patient. This blood sample is then placed in a centrifuge that spins the blood at a high enough speed in order to increase their concentration. The platelets and the blood plasma are injected into the injured area, often guided by ultrasound image.

The injection process takes no more than hour, including the time it takes to create and prepare the PRP. Frequency of injections will vary depending on the patient and type of injury. Some patients receive a series of injections over the course of several weeks, while other patients can experience relief after one session.


This revolutionary technique may be used to heal many common conditions.

  • Tennis elbow
  • Osteoarthritis of the knee, spine, shoulder and hip
  • ACL injuries
  • Achilles tendinitis
  • Ankle sprains

Am I a Candidate for Platelet Rich Plasma?


If you are suffering from a soft tissue injury such as tendonitis, tendinosis, tendon tears, ligament sprains or tears, loose ligaments, or muscle tears, you may be a candidate for Platelet Rich Plasma.

The ROM Clinic will always perform individual analysis of each patient to determine if Platelet Rich Plasma is the right treatment option for you.

What Are the Benefits of PRP Injections?


Results from PRP aim to accelerate the healing process of soft tissue injuries in cases such as unresponsive chronic pain, tendonitis symptoms, osteoarthritis symptoms, runner's knee, or lower back pain.

What Should I Expect After the Procedure?


Patients may experience throbbing and aching around the injection site once the local anesthetic wears off. This can last up top several days after the procedure. Patients who have had a PRP injection are advised to rest for a few days or weeks (if necessary) after the treatment in order to not push the injected tissue too quickly. Pain relief will generally start to occur within three to four weeks and continues to improve over a period of three to six months following an injection. The type of injury being treated will cause the recovery time to vary.

What Are the Risks of PRP Injections?


The main risks of Platelet Rich Plasma therapy are the same of any minimally invasive procedure, including risk of bleeding, infection and some pain during and after the procedure. Working with a qualified physician can minimize these risks.
