Platelet Rich Plasma Injection

Our blood contains a liquid element called plasma. It also consists of three main solid components: platelets, white blood cells, and red blood cells (RBCs, wbcs). Platelets are essential in the formation of blood clots. They also contain specific proteins called growth factors that aid in the healing process in our bodies. A high concentration of platelets and plasma is known as platelet-rich plasma or PRP. A specimen of normal blood only contains 6% platelets, while platelet-rich plasma contains 94% of platelets and 5 to 10 times the concentration of growth factors found in normal blood, so having greater healing properties.

Indications

PRP is a relatively new method of treatment for a range of orthopedic conditions such as fractures, arthritis, and injuries to the muscle, ligament, and tendon. PRP injections can assist in eliminating painful symptoms, help promote healing and reschedule joint replacement surgeries.

Procedure

About 10 ccs of blood will be first drawn by your doctor from a large vein in your elbow. The platelets are then separated from the remaining blood components by spinning the blood for 10 to 15 minutes in a centrifuge machine.

Then a local anesthetic is used to anesthetize the injured part of your body. The affected area is then given an injection of your blood that is rich in platelets. Your doctor may in some cases use ultrasound guidance for correct needle placement.

Post-Procedural Care

• Following your procedure, it is normal to experience some discomfort at the injection site for a couple of days.
• Your doctor will prescribe pain medications for you.
• Cold compresses can be used to relieve symptoms.
• Asked to stop using any anti-inflammatory medications.
• You can resume your regular activities, but you should refrain from any strenuous ones such as heavy lifting or strenuous exercises.
