This study is a prospective randomized controlled study of different arthroscopic treatments for refractory external humeral epicondylitis combined with platelet rich plasma (PRP) injection. The patients with intractable external humeral epicondylitis were randomly divided into groups before the operation. After the arthroscopic operation was completed, they were divided into a local PRP injection group and a control group (normal saline) to perform additional operations on the damaged tendons, each for up to half a year after the operation. In different time periods, the quantitative and qualitative indicators including pain, functional score, muscle strength, MRI performance, etc. were compared between groups at the same time period to evaluate the difference in the effect of arthroscopic treatment combined with PRP on the treatment of damaged tendons. Determine the effectiveness of PRP. At the same time, in the process of arthroscopic treatment, look for risk factors that affect the curative effect of intractable external humeral epicondylitis, as well as the causes and prevention of common complications.
