Percutaneous Ultrasonic Tenotomy for Refractory Common Extensor Tendinopathy After Failed Open Surgical Release: A Report of Two Cases.

Common extensor tendinopathy (CET) is a common, painful overuse and degenerative condition of the lateral elbow, affecting an estimated 2 million patients per year. Although many cases resolve with conservative treatment, recalcitrant cases may progress to open surgical intervention. For patients who do not improve with surgical management, treatment options are extremely limited. In this article, we present 2 cases of recalcitrant surgically treated CET successfully treated with sonographically guided percutaneous ultrasonic tenotomy with 1-year follow-up. To our knowledge, this is the first publication demonstrating successful treatment of recalcitrant CET after open surgical repair, with the use of ultrasonic tenotomy. LEVEL OF EVIDENCE: V.
