The human body is inevitably subjected to tissue repair and healing after trauma, and scar proliferation of different degrees occurs during the repair and healing. The scar tissue has strong contractility, which can damage the integrity of the human surface and the normal anatomical structure of the joint, resulting in disfigurement and joint movement dysfunction, causing great psychological burden and economic burden to the patient in terms of treatment. Currently, the common treatment method is surgical excision of the scar followed by suturing or implantation. However, after excision, the scar will re-grow and produce scar contracture. The lesion can be treated with implants within a certain range, but for large scars with hyperplasia and contracture, implantation is very difficult. We have conducted in-depth research on scar contracture and created the radiofrequency ablation technique to treat scar contracture, which has made breakthrough progress. Its characteristics: light damage, less patient pain, and remarkable efficacy.
