Extracapsular Arthroscopic Treatment for Refractory Tennis Elbow--Mid-and-short Term Retrospective Study of 50 Cases

Study Overview
=================
Brief Summary
-----------------
This study retrospectively analysed surgical outcomes of consecutive 50 cases to investigate the technical standard and clinical effect of extracapsular arthroscopic treatment for refractory tennis elbow.

Detailed Description
-----------------
To investigate the technical standard of extracapsular arthroscopic treatment for refractory tennis elbow. Consecutive 50 cases of refractory tennis elbow from 50 patients who underwent extracapsular arthroscopic surgery which performed independently by the same doctor from March 2012 to November 2016 was retrospectively analyzed. The key points of technical standard were summarized, including debridement, decortication and microfracture, suture under arthroscopy and postoperative cast fixation. Visual Analogue Scale(VAS), Mayo elbow performance score and Disability of Arm, Shoulder, and Hand outcome measure (DASH) were evaluated for postoperative results. The effects of various technical points were analyzed by rank sum test, independent sample t test, χ2 test and multiple logistic regression.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mayo Elbow Performance Score | Use Mayo Elbow Performance Score（MEPS） to evaluate the functional recovery of patients who received extracapsular arthroscopic treatment. MEPS ranges from 0 to 100, higher scores mean a better outcome. | 24 months | 
| Visual Analog Scale | Use Visual Analog Scale(VAS) to evaluate the pain recovery of patients who received extracapsular arthroscopic treatment. VAS ranges from 0 to 10, higher scores mean a worse outcome. | 24 months | 
| Disability of Arm, Shoulder and Hand score | Use Disability of Arm, Shoulder and Hand(DASH) score to evaluate the functional and pain recovery of patients who received extracapsular arthroscopic treatment. DASH ranges from 0 to 100, higher scores mean a worse outcome. | 24 months | 
| Activity of Daily Life recovery time | Use Activity of Daily Life(ADL) recovery time to evaluate the functional recovery of patients who received extracapsular arthroscopic treatment. | 24 months |
