About

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.

Full 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.
