EFFECTIVENESS: 4/5

While the literature is still somewhat sparse, recent reviews suggest PRP is an effective treatment when compared to placebo and other types of injections.

SELF CARE: 0/5

You won’t be doing this on your own!

COST: 2/5

There are many ads online and in the paper touting PRP treatments. Costs apparently vary widely, but some online sites quote fees from $500-$1500, and others of $300 per injection. Usually more than one is required. PRP is still considered “investigational” and therefore not covered by most insurance carriers.

USEFULNESS (overall rating): 4/5

PRP injections involve drawing some of your own blood (usually 1-2 tubes) which is then spun down to yield increased concentrations of platelets. Platelets are a crucial component of blood important in healing, and they contain growth enhancing factors thought to increase healing. The plasma is then injected into the area of damage at the lateral epicondyle.

PRP is being used on a wide variety of joint, tendon, and muscle conditions. There are various types of products, and more recent research suggests the type with leukocyte rich PRP appears to be more effective.

PRP appears in some studies to be more effective than cortisone.  If more conservative measures have not helped, PRP injection is a reasonable alternative.
