About this study

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.

Inclusion criteria

Diagnosis was refractory tennis elbow;
Standard extracapsular method was used for surgery.

Exclusion criteria

Patient had past history of joint infection, joint tuberculosis, or osteomyelitis, or the upper limb had undergone surgery within the past 6 months;
Diagnosis was combined with severe heart, brain, kidney, or another organ dysfunction;
Case was complicated with other serious elbow joint diseases or injuries;
Patient did not sign the informed consent form.

Treatment and study plan

Extracapsular arthroscopy

Procedure

Extracapsular arthroscopy method was used to treat refractory tennis elbow

Primary outcomes

Mayo Elbow Performance Score

Time frame: 24 months

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.
Visual Analog Scale

Time frame: 24 months

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.
Disability of Arm, Shoulder and Hand score

Time frame: 24 months

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.
Activity of Daily Life recovery time

Time frame: 24 months

Use Activity of Daily Life(ADL) recovery time to evaluate the functional recovery of patients who received extracapsular arthroscopic treatment.
