Tendinosis of the extensor carpi radialis brevis: an evaluation of three methods of operative treatment.

Many procedures have been described for treating lateral epicondylitis with good success. The purpose of this report is to compare 3 operative methods for treatment of recalcitrant lateral epicondylitis-open, arthroscopic, and percutaneous. All patients with lateral epicondylitis who were operated on over a 7-year period were retrospectively reviewed. A minimum of 3 months of conservative care before surgery had failed in these patients, and they had a minimum of 2 years of follow-up. Concomitant pathology, complications, and necessary further care were noted. The outcomes were evaluated preoperatively and postoperatively with the Andrews-Carson score and visual analog scale scores for pain at rest, worst pain, and pain with activity. We included 109 patients in the study: 24 percutaneous, 44 arthroscopic, and 41 open procedures. The mean duration of conservative care was 13.2 months, including 2.5 conservative measures and 1.35 cortisone injections. The mean follow-up was 47.8 months. The preoperative Andrews-Carson score was 160.3. The postoperative Andrews-Carson score was 195. There was a statistically significant difference between preoperative and postoperative Andrews-Carson scores for each of the groups. There were no significant differences among the populations regarding age, gender, dominance, conservative measures used, cortisone injections, recurrences, complications, failures, visual analog scale scores, and preoperative and postoperative Andrews-Carson scores. In addition, no difference in outcome scores was noted when intraarticular and concomitant pathology was addressed in comparison to the population in which tendinosis alone was addressed. Open, arthroscopic, and percutaneous treatments of lateral epicondylitis offer 3 highly effective ways for the clinician to address this common clinical problem.
