Does use of the 70 degrees arthroscope improve the outcomes of arthroscopic debridement for chronic recalcitrant tennis elbow?

摘要

Background: The use of a 70 degrees arthroscope has been reported to provide better visualization of the extensor carpi radialis brevis origin at the lateral epicondyle. We aimed to compare the surgical outcomes of arthroscopic debridement using an additional 70 degrees arthroscope with those using a 30 degrees arthroscope alone in the treatment of chronic recalcitrant tennis elbow.
