It is possible to run after meniscus cruciate ligament surgery, but only after full recovery. It usually takes about 3 months to recover from meniscus cruciate ligament surgery, and during the recovery period, you should pay attention to bed rest and reduce strenuous exercise to promote the recovery of the body. In the late stage of recovery, you can do some early rehabilitation exercises and some moderate activities such as walking out of bed and going up and down stairs to prevent muscle adhesion, but be careful to avoid weight-bearing exercise, and running should also be carried out only after full recovery, about three months. In addition, during the recovery period, we should pay attention to a light diet, eat more protein-rich foods such as eggs, milk, etc., to promote the healing of the postoperative wound and return to normal life as soon as possible.
