Kwon BC, et al. - A total of 68 consecutive patients who received arthroscopic débridement for chronic recalcitrant tennis elbow were retrospectively reviewed by the researchers in order to contrast the surgical outcomes of arthroscopic débridement using an additional 70° arthroscope with those using a 30° arthroscope alone in the treatment of chronic recalcitrant tennis elbow. In visual analog scale pain scores and Quick Disabilities of the Arm, Shoulder and Hand scores at 3 months, 6 months, and final follow-up, both groups revealed meaningful and progressive betterments. Nonetheless, no important variations were discovered between the groups at all time points of measurement relative to outcome measures. Moreover, the proportions of patients with superior outcomes and those with clinically significant betterments were similar across the groups. Therefore, in the outcomes of arthroscopic débridement for chronic recalcitrant tennis elbow, the use of an additional 70° arthroscope did not give an important betterment.
