A small amount of blood is taken from your arm. The blood is placed into a centrifuge to separate red blood cells and other components from the platelets to produce PRP. Using imaging guidance to monitor the position of the needle within the injured tissue, the radiologist injects the PRP.
Immediately following the injection, the PRP releases cellular growth factors that trigger the body’s healing response. You may experience inflammation and soreness as the body’s healing process begins. In fact, there may be no symptom relief for a period of 2 to 8 weeks. You will want to treat the injected area with care, like you would with a new injury. Depending on the area that is injured, crutches or a sling may be recommended to minimize the use of the area as healing begins.
In the months that follow, inflammation and pain will decrease and new tissue will begin to develop. As this tissue matures, it causes repair and strengthening of the tendons, ligaments, discs or joints. Pain and inflammation will decrease as this occurs.
Frequently, chronic injuries require more than one injection. Depending on the severity and duration of the injury, an additional PRP injection may be suggested.
