We assessed the effect PRP injection on pain and function in patients with lateral epicondylitis where conservative management had failed.


We prospectively reviewed 34 patients. The mean follow-up was 26 weeks (range 6-114 weeks). We used the Oxford Elbow Score (OES) and progression to surgery to assess outcomes.


88.2% improved their OES. 8.8% reported symptom progression. One patient had no change. No patients suffered adverse reactions. Two patients underwent an open release procedure. One had the injection repeated.


An injection of PRP improves pain and function in patients suffering from LE where conservative management has failed.
