Tendon rupture recovery time is usually about two weeks to one month. Tendon rupture is mostly caused by violent trauma that leads to strong contraction of the tendon, or the interruption of the continuity of the tendon caused by cutting with a sharp instrument or crushing by a machine. The patient’s symptoms are mostly pain, swelling, skin rupture and bleeding, and corresponding movement disorders of the joint, such as flexor tendon rupture may appear limb flexion dysfunction, extensor tendon may be accompanied by limb or even dysfunction, and the patient with serious injury may be accompanied by tendon defect. The vast majority of patients with tendon rupture require surgical treatment to repair the severed end of the tendon with a tendon anastomosis. Patients with partial tendon defects can be treated with a tendon graft or tendon transfer anastomosis of the ruptured tendon. Postoperative immobilization in a cast is required for about 2-4 weeks. In addition, tendon adhesions may occur during the healing process after tendon rupture, so patients need active functional exercises after removal of the cast in order to maximize the restoration of tendon function.
