Brief summary
The aim of this study was to investigate the exploration history, key theories, methods, and techniques involved in the evolution from the intracapsular method to the extracapsular method for arthroscopic treatment of tennis elbow, and explore the effectiveness and safety of extracapsular method on the basis of retrospective analysis of 43 cases.
Detailed description
Background: Arthroscopic surgery is widely used in the treatment of refractory tennis elbow due to its advantages of minimally invasive, safe and direct vision. Intra-capsular arthroscopy(intracapsular method), which is performed via natural cavity, is the mainstream arthroscopic procedure. However, intracapsular method requires the damage of joint capsule and may cause intraoperative neurovascular injury and other complications. In view of the defects of intracapsular method, the surgical scheme of the extracapsular arthroscopy (referred to as extracapsular method) has emerged. The aim of this study was to investigate the exploration history, key theories, methods, and techniques involved in the evolution from the intracapsular method to the extracapsular method for arthroscopic treatment of tennis elbow, and explore the effectiveness and safety of extracapsular method. Methods: Qualitative data were collected via focus group interview. 7 surgeons who were selected through purposive sampling discussed on the theories, methods, and technical specifications of the transition from intracapsular method to extracapsular method. Qualitative data were analysed using NVivo11. Quantitative data of consecutive 43 patients were analysed to evaluate the effectiveness and safety of the extracapsular method. Descriptive analysis was conducted to analyse the demographic characteristics and clinical outcomes after surgery.

Inclusion criteria
1. Diagnosis was refractory tennis elbow; 2. Standard extracapsular method was used for surgery.
Exclusion criteria
1. Patient had past history of joint infection, joint tuberculosis, or osteomyelitis, or the upper limb had undergone surgery within the past 6 months; 2.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mayo Elbow Performance Score | 12 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 | 12 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 | 12 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 | 12 months | Use Activity of Daily Life recovery time to evaluate the functional recovery of patients who received extracapsular arthroscopic treatment. |
