[Treating intractable lateral epicondylitis by extracurricular arthroscopic operation based on pressure point].

OBJECTIVE:To evaluate clinical efficaly of intractable lateral epicondylitis by extracurricular arthroscopic operation based on pressure point. METHODS:From October 2015 to September 2017, 19 patients with intractable lateral epicondylitis were treated with extraarticylar arthroscopic operation based in pressure point. Among patients, including 7 males and 12 females, aged from 33 to 62 years old with an average of(43.16±8.12) years old, The courses of conservative treatment ranged from 7 to 41 months, with an average of(15.47±7.08) months. Postoperative complications were observed, VAS score and Mayo score before and after operation at 3 months were observed and compared. RESULTS:All patients were followed up from 6 to 26 months, with an average (17.16±5.25) months. No infection, skin necrosis and nerve injury occurred. No group weakness occurred within six months after operation. VAS score decreased from 4.42±1.17 before operation to 0.53±0.61 after operation at 3 months. Mago was improved from 62.63±7.88 before operation to 93.42±5.28 after operation at 3 months. According to Mayo score, 17 cases got excellent results, and 2 cases were good. CONCLUSIONS:Intractable lateral epicondylitis by arthroscopic extracurricular operation based on pressure point, which deal with main extracurricular root cause, could anatomical level is understand easily, field of vision is good and diseased tissue is cleaned up thoroughly, and has obvious curative effect.
