Exercises after ligament rupture surgery include muscle strength training and joint mobility training. The whole body ligament is very much, different parts of the specific training action will be different, to the knee joint, for example, mainly including ankle pump exercises, quadriceps training and joint flexion and extension, other parts of the training ideas are similar. 1. Ankle pump exercises: daily active ankle flexion and extension training, flexion and extension requirements up to the maximum angle to maintain 3 to 5 seconds, to let the muscles continue to maintain contraction. 2. Quadriceps training: static contraction training requires active contraction of the quadriceps, and the need to maintain muscle tension for 3 to 5 seconds, daily adherence. 3. Joint training: daily joint flexion and extension activities, about 10 to 20 times a day, divided into two times, usually one in the morning and one in the afternoon, to prevent joint stiffness or adhesion, and strive to restore joint mobility. Post-operative ligament rupture training should be carried out under the guidance of a doctor or professional rehabilitation therapist, so as to avoid secondary injuries caused by improper methods.
