Brief summary
Arthroscopic surgery is effective in treating osteochondral lesions of the talus. However, there are still some patients with postoperative ankle pain. This study aims to investigate the clinical efficacy of shock wave adjuvant therapy in the treatment of postoperative pain caused by cartilage injury of talus after arthroscopy and to provide basis for further popularization and application.
Detailed description
Arthroscopic surgery is effective in treating osteochondral lesions of the talus. However, there are still some patients with postoperative ankle pain. This study was conducted to investigate the clinical efficacy of shock wave therapy in the treatment of postoperative pain caused by cartilage injury of talus after arthroscopy. Patients with osteochondral lesions of the talus treated by arthroscopic microfracture surgery and still complained ankle pain three months after surgery were enrolled. Radial extracorporeal shock wave therapy was used to give energy to the injured region of the talus and the adjacent area.Treatment was done once a week for 5 consecutive weeks. After shock wave therapy,the patients were followed by Visual Analogue Scale (VAS), the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale(AOFAS-AHFS) , and followed finally by Magnetic Resonance Imaging(MRI) of the ankle.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of VAS scores before and after shock wave therapy | 6 weeks, 12 weeks and last follow-up at an average of 2 years after shock wave therapy | The Visual Analogue Scale scores of the patients before and after the shock wave therapy are recorded. The scale ranges from 0-10 points, and decreases of the value represent a better outcome. The data analyses are performed with SPSS version 16.0 statistical software. Continuous variables are expressed as mean ± standard deviation, and 95% confidence intervals are determined. The data are compared by paired t test or rank-sum test. P value \< 0.05 is considered as statistically significant. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of AOFAS scores before and after shock wave therapy | 6 weeks, 12 weeks and last follow-up last follow-up at an average of 2 years after shock wave therapy | The American Orthopaedic Foot & Ankle Society scores of the patients before and after the shock wave therapy are recorded. The scale ranges from 0-100 points, and increases of the value represent a better outcome. The data analyses are performed with SPSS version 16.0 statistical software. Continuous variables are expressed as mean ± standard deviation, and 95% confidence intervals are determined. The data are compared by paired t test or rank-sum test.
