Abstract
Purpose: To compare the clinical effects of radiofrequency (RF)-based microtenotomy and arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon in patients with recalcitrant lateral epicondylitis through a prospective randomized controlled study. Methods: A total of 46 patients were randomly assigned to receive arthroscopic release (group A, 24 patients) or RF-based microtenotomy (group B, 22 patients). The visual analog scale (VAS) score for pain, flexion-extension arc, operation time, Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH), Mayo Elbow Performance Score (MEPS), and grip power of groups A and B were compared during the recovery phases for up to 2 postoperative years. Results: Both groups showed statistically significant functional improvement compared with their preoperative grip strength and DASH, VAS, and MEPS scores at 2 years after surgery (P <.05). There were no differences in postoperative pain relief or functional restoration between the 2 groups during the recovery phases, however the mean operation time for group B (41.4 ± 5.2 minutes) was significantly shorter than that for group A (15.6 ± 3.6 minutes, P <.001). In group B, 1 patient underwent revision surgery due to postoperative ECRB rupture, and 1 patient in group A underwent open release for persistent postoperative discomfort. Conclusions: RF-based microtenotomy for treating recalcitrant lateral epicondylitis provided clinical outcomes comparable with those from arthroscopic release of ECRB tendon during the recovery phase. RF-based microtenotomy is considered as one of the surgical procedures for treating recalcitrant lateral epicondylitis, with the advantages of reliable elbow functional restoration and significantly shorter operation time.
