A randomized comparison of open and arthroscopic Nirschl debridement for refractory lateral epicondylitis / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare open and arthroscopic methods for treatment of recalcitrant lateral epicondylitis.</p><p><b>METHODS</b>A prospective trial of 26 patients (28 elbows) with recalcitrant lateral epicondylitis were treated between May 2006 and September 2008. The mean duration of conservative care was 23. 0 months (4 - 60 months). The mean follow-up was 17.4 months (4 - 32 months). The patients were randomized divided into two groups, 13 elbows with an open Nirschl procedure and 15 with an arthroscopic Nirschl procedure. All patients had pre- and post-operative assessment using VAS (visual analog scale) scores, Mayo 12 points elbow scores, time of return to work or sports, satisfaction, and so on.</p><p><b>RESULTS</b>There were no significant differences in VAS scores at rest and activities of daily living, time of return to work or sports and satisfaction between the two groups. But there was a statistically significant difference in VAS scores at work and sports and Mayo 12 points elbow scores between the two groups. 100% of the patients had excellent or good results in the open group and 93.3% in arthroscopic group. There were no severe complications in this series.</p><p><b>CONCLUSIONS</b>Both open and arthroscopic Nirschl procedures are valid and reliable treatments for patients with refractory lateral epicondylitis. The patients in the open group have a better function in the return-to work and sports postoperatively than the arthroscopic group.</p>
