Effectiveness of Platelet Rich Plasma Injections

Regenerative medicine therapies include prolotherapy, platelet rich plasma injections and stem cells.

Platelet rich plasma (PRP) involves the use of platelet derived growth factors in the healing of tendon and muscle injuries.  The process includes collection of a patient’s blood with isolation and concentration of the platelets.  The concentrated platelets are then injected into the damaged tissue accelerating the healing process.

PRP therapy has made the headlines and utilized by many professional athletic teams.

Does it work?

According to Robert J. de Vos, M.D., in his recent publication in the Journal of American Medial Association, PRP injections did not significantly improve pain or activity level in patients with long-standing history of Achilles tendon irritation.  What this article did not discuss was the therapeutic effect of simply irritating the tendon (percutaneous tenotomy) which has been demonstrated to be effective.

Regenerative medicine has an increasing number of tools.  At the Centeno-Schultz Clinic it is our goal to utilize the appropriate regenerative therapy for the best possible clinical outcome.

PRP and Athletic Injuries

 Wanted to share the treatment of a local sports personality who responded well to PRP therapy.

Patient suffered an injury to the semimembranous which is one of the three muscles that comprise the hamstring.  He had significant pain in the back of this thigh which limited his ability to run.  he had point tenderness on examination with swelling and bruising.

 The semimembranosus muscle allows us to flex the knee, extend the hip and rotate our hip inwardly when the knee is flexed.

MRI demonstrated a tear in the muscle which is identified by the white arrow.

Patient underwent  a concentrated injection of his own platelets into the area of injury to stimulate repair.  This concentrate is referred to as platelet rich plasma (PRP).  Platelets are rich in growth factors which have been demonstrated to promote natural healing. After two injections the patient had 80% improvement and was able to return to playing.  PRP therapy affords patients a natural healing treatment with minimal downtime and the potential for significant results. 

PRP has been successfully used in professional athletes as witnessed by the treatments of Hines Ward  prior to the Superbowl.

PRP is just one of the regenerative therapies utilized at he Centeno-Schultz Clinic.
