Background: An effective treatment for the elbow recalcitrant lateral epicondylitis is arthroscopic surgery. This studyevaluated the midterm results of treating recalcitrant lateral epicondylitis with arthroscopic surgery.Methods: A total of 40 subjects with recalcitrant lateral epicondylitis prepared for arthroscopic surgery on their elbowsparticipated in this study. The elbow function was evaluated using the Quick disabilities of the arm, shoulder, and hand(Quick DASH) score. Pain intensity was assessed before and after the surgery by the visual analog scale (VAS). Gripand pinch strengths were assessed by a dynamometer.Results: In this study, the mean age of the participants was 42.9±6.4 years. The average follow-up time was 42months. The mean of VAS (pain intensities) were 7.05 and 3.20 before and after the surgery, respectively (P=0.001).The Quick DASH score decreased from 63.18 to 25.68 from before to after the surgery (P=0.001). The mean gripstrength of the operated and nonoperated sides was not significantly different after the surgery.Conclusion: Arthroscopic surgery seems to be an effective method with few complications in patients suffering froman elbow recalcitrant lateral epicondylitis in the midterm follow-up.Level of evidence: II
