Arthroscopic Treatment With Ulnar Nerve Release for Elbow Osteoarthritis

This study is a prospective randomized controlled study of arthroscopic release for primary osteoarthritis of the elbow with stiffness with or without ulnar nerve release. The patients with primary osteoarthritis of the elbow with stiffness, which ulnar neuropathy proven by electromyography without clinical symptoms, were randomly divided into groups before the operation. Before the arthroscopic operation was began, the procedure of ulnar nerve release was performed according to the group(release group or unrelease group). In different time periods postoperatively, the quantitative and qualitative indicators including pain, functional score, muscle strength, etc. were compared between groups at the same time period to evaluate the difference in the effect of arthroscopic treatment combined with ulnar nerve release.
