Tendon injury can be treated conservatively or surgically according to the degree of injury. 1. Conservative treatment: If the tendon is partially damaged and the joint movement is normal, conservative treatment can be adopted, applying a brace or plaster to immobilize for 1 month, and taking oral capsules to promote healing under the instruction of the doctor. Full recovery will take about 2 months. 2. Surgery: If the tendon is completely ruptured or open rupture, it is necessary to take surgical treatment and perform incisional tendon anastomosis. After the surgery, the tendon should be immobilized by plaster for 1 month and then perform functional exercise, and the full recovery will take about 2 months. Therefore, the specific treatment plan for tendon injury depends on the degree of injury, and the best treatment plan will be made according to each individual. When tendon injury occurs, it is recommended to consult a doctor in time and standardize the treatment under the guidance of a professional doctor, so as to avoid delaying the condition.
