The effect of platelet-rich plasma injection on lateral epicondylitis following failed conservative management.

Objective: We assessed the effect PRP injection on pain and function in patients with lateral epicondylitis where conservative management had failed.
Methods: 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.
Results: 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.
Conclusion: An injection of PRP improves pain and function in patients suffering from LE where conservative management has failed.
