Tendon rupture usually takes about 2~3 months to fully recover. The exact recovery time needs to be judged according to the severity of the injury and the later rehabilitation exercises. Tendon rupture requires surgical treatment and needs to be immobilized with a cast for about 4~6 weeks after surgery. After removing the cast, you need to carry out functional exercises, such as active exercise, passive exercise and so on. Because of the long time immobilization, it is easy to cause adhesion between the tendon and the surrounding tissues, and joint stiffness and mobility disorders occur. It usually takes about 2~3 months to recover the limb function after rehabilitation exercise. However, if the injury is more serious, with localized infection, missing tendon, etc., the recovery time is longer. Tendon rupture needs timely medical treatment, in the recovery period, need to be under the guidance of the physician to carry out rehabilitation exercises, which is conducive to the recovery of limb function.
