Platelet Rich Plasma

Our blood consists of a liquid component known as plasma. It also consists of three main solid components which include the red blood cells (RBCs), white blood cells (WBCs), and platelets. Platelets play an important role in forming blood clots. They also consist of special proteins, known as growth factors, which help with our body’s healing process. Platelet-rich plasma or PRP is a high concentration of platelets and plasma. A normal blood specimen contains only 6% platelets, while platelet-rich plasma contains 94% of platelets and 5 to 10 times the concentration of growth factors found in normal blood, thus greater healing properties.

Indications

PRP is a relatively new method of treatment for several orthopedic conditions such as muscle, ligament, and tendon injuries; arthritis; and fractures. PRP injections can help alleviate painful symptoms, promote healing and delay joint replacement surgeries.

Procedure

Your doctor will first draw about 15 ccs of blood from the large vein in your elbow. The blood is then spun in a centrifuge machine for 5 minutes to separate the platelets from the remaining blood components.

The injured part of your body is then anesthetized with a local anesthetic. The platelet-rich portion of your blood is then injected into your affected area. In some cases, your doctor may use ultrasound guidance or an in-office needle with a camera for proper needle placement.

Post-Procedural Care

• It is normal to feel some discomfort at the injection site for a few days after your procedure.
• You may be prescribed pain medications by your doctor.
• You may use cold compresses to alleviate your symptoms.
• You will be instructed to stop any anti-inflammatory medicationsfor 1 week prior to and 1 week after the injection procedure.
• You may resume your normal activities but should avoid any strenuous activities such as heavy lifting or exercises.

Risks and complications

There are very minimal risks associated with PRP injections. Some of the potential risks include

• Increased pain at the injection site
• Infection
• Damage to adjacent nerves or tissues
• Formation of scar tissue
• Calcification at the injection site
