Lee JH, et al. - Two surgical procedures viz radiofrequency (RF)-based microtenotomy and arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon for recalcitrant lateral epicondylitis were compared herein, in terms of clinical impacts. The outcomes afforded by RF-based microtenotomy were found to be comparable with those from arthroscopic release of ECRB tendon during the recovery phase, however, RF-based microtenotomy provided the advantages of reliable elbow functional restoration and significantly shorter operation time.
