The common sequelae of tendon rupture are: 1. If the tendon rupture is not treated, the sequelae are more serious, and the ruptured tendon will contract and adhere to the surrounding tissues, resulting in the disappearance of the function of the tendon; 2. After the tendon rupture surgery, there will also be tendon adhesion sequelae, showing dysfunction such as flexion and extension, which requires functional exercises under the guidance of a doctor to restore the corresponding function. For tendon adhesions need to actively carry out flexion and extension functional exercises at an early stage under the guidance of a doctor to restore the function as soon as possible.
