Background: Lateral epicondylitis treatment is still controversial, most of patients managed with conservative measures including rest, NSAIDs and physiotherapy. However, some of them do not respond well and have to be managed surgically. That can be done either open or arthroscopic technique. The aim is to study the technique and functional outcome of arthroscopic management of lateral epicondylitis. Design: Prospective study. Methods: Between December 2016 and July 2019, 26 (16 female and 10 male) patients aged (28-57) presented with resistant lateral epicondylitis treated with elbow arthroscopy. Functional assessment preoperative and postoperative using VAS and Mayo score was done to all patients. The study included patients with elbow pain and weak grip symptoms with failure of conservative treatment for at least 6 months excluding revision, infected, rheumatoid arthritis patients, and previous steroid injection in past 3 weeks. Results: The mean operative time was 65 minutes; the mean follow-up time was 20.3 months. The patients were reintegrated into their activities at 21 days postoperatively. Pain as a sign and capital symptom improved significantly within 12 days of surgery. Mayo score improved postoperatively. The Mean
SD preoperative Mayo score was 59.5
7.23 and to 96.5
3.03 after follow up for six months. The Mean
SD preoperative VAS score was 8.9
0.76 and raised to 0.84
0.74 and to 0.5
0.5 after follow up for six months (Table 2). All patients were satisfied because of small wound size with cosmetic suture, rapid return of movement of elbow after operation and rapid improvement of pain level. One patient developed transient forearm neuropraxia that resolved within three weeks with neurotonics
