The investigators are testing the efficacy of a new, FDA-approved bioinductive patch in lateral epicondylitis (tennis elbow) patients. A bioinductive patch is an implant that may foster tendon regrowth and healing following surgery. Patients will be randomize into one of two groups: control and investigational. Patients in the control group will receive the normal surgery for patients who do not respond to physical therapy, lifestyle changes, and anti-inflammatory treatment. Patients in the experimental group will receive the same surgical treatment, with the addition of the bioinductive patch. This patch will be implanted during surgery. Then, using a combination of ultrasound studies and other measures, the investigators will assess how well the patch works compared to surgery alone.
