Purpose

Controversy exists with regards to the etiology and treatment of lateral epicondylitis and the role of the lateral capsule in this pathology. The aim of this study was to compare arthroscopic lateral capsule resection with or without extensor carpi radialis brevis (ECRB) tendon debridement for treatment of lateral epicondylitis.

Methods

This is a retrospective study of 38 patients who underwent arthroscopic surgery for LE with two different techniques: Eighteen patients were treated with arthroscopic lateral capsular resection (LCR) + ECRB debridement and 20 patients were treated with arthroscopic LCR alone, without ECRB debridement. Both groups were assessed with Quick Disabilities of the Arm, Shoulder and Hand (QDASH) score for function and Visual Analog Scale (VAS) score for pain.

Results

Quick DASH scores were 12 \(\pm \) 5 and 13 \(\pm \) 4 at Groups 1 and 2, respectively, without any statistically significant difference. VAS pain scores were 15 \(\pm \) 2 for both groups. VAS function scores were 85 \(\pm \) 22 and 86 \(\pm \) 18 at Groups 1 and 2 respectively. Sick leave periods in terms of weeks were 7 \(\pm \) 5 and 7 \(\pm \) 4 at Groups 1 and 2, respectively. There was no statistically significant difference in outcome of the two groups compared in terms of VAS pain, function scores, failure (re-operation) rates and sick leave period at the end of final follow-up.

Conclusion

Both arthroscopic LCR alone and Arthroscopic LCR with ECRB debridement for the management of refractory LE provide significant improvement in pain and function. Isolated Arthroscopic LCR could be a sufficient surgical treatment for refractory LE. Thus, ECRB debridement or release may not be necessary in every case.

关节镜下外侧囊切除术足以治疗外侧上con炎。

目的

关于外侧上con炎的病因和治疗以及外侧包膜在这种病理中的作用存在争议。这项研究的目的是比较关节镜下外侧囊膜切除术与无或有伸肌腕car短肌（ECRB）腱清创术治疗外侧epi上炎。

方法

这是一项回顾性研究，对38例采用两种不同技术进行LE的关节镜手术患者进行了回顾性研究：18例行关节镜外侧囊切除术（LCR）+ ECRB清创术治疗，20例单独行关节镜LCR治疗，无ECRB清创术。两组均通过手臂，肩部和手部快速残疾（QDASH）评分进行功能评估，并使用视觉模拟量表（VAS）评分进行疼痛评估。

结果

快速DASH分数在第1组和第2组分别为12 \（\ pm \） 5和13 \（\ pm \） 4，在统计学上无显着差异。两组的VAS疼痛评分均为15 \（\ pm \） 2。第1组和第2组的VAS功能分数分别为85 \（\ pm \） 22和86 \（\ pm \） 18。第1组和第2组的病假周数分别为7 \（\ pm \） 5和7 \（\ pm \） 4。在最终随访结束时，两组的结局在VAS疼痛，功能评分，衰竭（再次手术）率和病假期间相比均无统计学差异。

结论

单独的关节镜LCR和带有ECRB清创术的关节镜LCR都可用于治疗难治性LE，从而在疼痛和功能上有显着改善。孤立的关节镜LCR可能是难治性LE的足够手术治疗。因此，并非在每种情况下都需要ECRB清创或释放。
