Arthroscopic Biportal Visualization and "Precise Resection" for Recalcitrant Lateral Epicondylitis Lesion.

Refractory lateral epicondylitis poses a significant clinical challenge. In patients with persistent symptoms refractory to conservative treatment, surgical intervention represents an effective approach for achieving durable symptomatic relief. Advances in arthroscopic techniques now offer a more minimally invasive and refined approach. While there is no consensus regarding the superiority of one arthroscopic treatment over another, resection of the lesion tissue remains a critical consideration. This article describes an arthroscopic extensor carpi radialis brevis tendon resection technique, which facilitates precise visualization and targeted resection of pathological tendon tissue, avoiding excessive resection of healthy tissue or incomplete resection of pathological lesions, while simultaneously addressing any concomitant intra-articular pathology.
