Once a tendon in the leg is ruptured, it takes about 4 weeks to heal, but at least 6 weeks to 3 months to fully recover. Tendons in the legs are generally strong and once they are ruptured, the recovery time is relatively long, and since the legs involve weight bearing, the load on the tendons of the lower extremities is also very high once they are weight bearing. Therefore, for the leg tendon rupture, we should be very cautious, and only after confirming that the tendon has fully recovered, can we gradually put weight on the ground. In addition, after the tendon has recovered, it is important not to do too much vigorous activity in the early stages to avoid re-rupture of the tendon. In the early stage of tendon rupture, it is necessary to take reasonable measures to repair the tendon as soon as possible, such as local repair or reconstructive surgery. After the tendon has healed to a certain degree, the patient should do functional exercises under the guidance of the doctor to promote faster and better healing of the tendon and restore the corresponding function of the joint.
