Operative management of lateral epicondylitis can be managed with percutaneous, arthroscopic, or open surgical release. Extraarticular arthroscopic release is a new technique, and no study has compared its outcomes and risk profile.
A 26-patient cohort was reviewed before and after extraarticular arthroscopic release, which was performed by the senior author. The Mayo Elbow Performance Scores were used as a functional outcome score and obtained via a phone interview. Results were analyzed using a paired t-test with a statistical significance set at < .05.
Of the 26 patients, 10 were being treated under workers compensation. Preoperative Mayo Elbow Performance Score was 47.5, and the postoperative score was 90.2 with a significant difference of 42.7 ( value = .05). The workers compensation group scored 13.3 points lower postoperatively than the remainder of patients, which was shown to also be significant with a value of .002.
The advantage of extraarticular arthroscopic release was better visualization of affected structures, which improved accuracy of debridement, and a small capsulotomy, which decreased the risk of a transient radial nerve palsy. Overall, extraarticular arthroscopic results were found to be good and comparable to the results of other operative techniques with the added advantage of a lower risk profile.
肱骨外上髁炎的手术治疗可采用经皮、关节镜或开放手术松解。关节镜下关节外松解是一种新技术，尚无研究比较其疗效和风险状况。
对由资深作者实施关节镜下关节外松解术的26例患者队列进行术前和术后评估。采用梅奥肘关节功能评分作为功能结局评分，通过电话访谈获得。使用配对t检验分析结果，设定统计学显著性水平为<0.05。
26例患者中，10例接受工伤赔偿治疗。术前梅奥肘关节功能评分为47.5，术后评分为90.2，差异显著，为42.7（P值=0.05）。工伤赔偿组术后得分比其余患者低13.3分，P值为0.002，差异也具有显著性。
关节镜下关节外松解的优点是能更好地观察受影响结构，提高清创准确性，且关节囊切开小，降低了短暂性桡神经麻痹的风险。总体而言，关节镜下关节外松解的结果良好，与其他手术技术的结果相当，且具有风险较低的额外优势。
