Platelet Rich Plasma Therapy

About PRP Therapy

PRP therapy offers a promising solution to accelerate healing of tendon injuries and osteoarthritis naturally without subjecting the patient to significant risk. PRP is an emerging treatment in a new health sector known as “Orthobiologics.” The philosophy is to merge cutting edge technology with the body’s natural ability to heal itself.

Blood is made of RBC (Red Blood Cells), WBC (White Blood Cells), Plasma, and Platelets. When in their resting state, platelets look like sea sponges and when activated form branches. Platelets were initially known to be responsible for blood clotting. In the last 20 years we have learned that when activated in the body, platelets release healing proteins called growth factors. There are many growth factors with varying responsibilities, however cumulatively they accelerate tissue and wound healing. Therefore after increasing the baseline concentration of these platelets, we are able to deliver a powerful cocktail of growth factors that can dramatically enhance tissue recovery.

PRP History and Current Studies

PRP was initially used over 20 years ago in the Dental community to enhance wound healing in cancer patients with jaw reconstruction. Soon afterwards its applications extended across many fields of medicine from cardiovascular surgery to orthopaedics. Multiple studies are underway to help further refine the treatment and demonstrate its efficacy.

Drawing of Blood

Preparation of blood for PRP injection

First, a small amount of blood is drawn from the patient’s arm. The blood is then placed in a centrifuge that spins the blood for approximately 15 minutes. This step removes the unwanted components of blood that are not primarily responsible for healing including: plasma, WBC’s and RBC’s. What remains is an increased concentration up to 10x above baseline of platelets, which are rich in healing properties called growth factors. During this time, the patient receives either local anesthetic (injected) or conscious sedation (via IV), as determined beforehand by the physician and patient.

PRP Injection

Using musculoskeletal ultrasound, the area of injury is properly identified and marked. The injection is performed with ultrasound guidance to ensure that the appropriate target is reached within a millimeter.

The patient rests afterwards for 5-10 minutes and is discharged home with post procedure instructions. Increased pain may result for approximately 7 days following the injection which is not uncommon. This represents part of the healing process.

Follow Up

Follow up is usually in 4 weeks, when another ultrasound will be performed to reassess the area of injury. At that time we will determine if a second injection is required. For most cases between 1-3 injections is required at 4 week intervals. However for osteoarthritis injections a 3 injection series is required at 4 week intervals. Patients are encouraged to participate in physical therapy following the injection which enhances recovery.
