Rehabilitation exercises after ligament reconstruction plus meniscus suture mainly include muscle strength training, joint mobility training, balance and stability training. 1. Muscle strength training: after ligament reconstruction with meniscus suture, early attention must be paid to braking and resting, and it can be considered to carry out lower limb muscle strength training through isometric contraction without causing joint movement, so as to prevent the problem of muscle atrophy. 2. Joint mobility training: ligament and meniscus injuries may affect the range of motion of the knee joint, so if the patient recovers well after the operation, he can begin to carry out joint mobility training, such as passive pulling and active contraction of the knee joint with the way to exercise. 3. Balance and stability training: If the internal structure of the knee joint has completely healed and stabilized after the operation, and there are no obvious symptoms of pain and swelling, it is necessary to carry out balance and stability training, such as the transition from double-leg weight-bearing to single-leg weight-bearing exercises, in order to prevent balance function from declining or gait abnormality in the later stage of the problem. In the early postoperative period, it is important to take rest and not to move the local joints too early to avoid re-injury. Ligament reconstruction and meniscus suture postoperative rehabilitation, it is recommended to carry out under the guidance of a professional doctor, do not blindly self-rehabilitation training, to avoid adverse consequences.
