If a patient has a ligament rupture, surgery should be performed. Because once a ligament rupture occurs, it will lead to the interruption of the continuity and integrity of the ligament area, which will affect the stability of the bone and joint area, and it is easy to have abnormal friction of the bone and joint area during activities, which will lead to traumatic arthritis at a later stage or cause premature degeneration of the joints, leading to osteoarthritis, and it will seriously affect the joints in flexion, extension and force activities, which will affect the patient’s normal life. Therefore, after a patient has a ligament rupture, it is important to consult a doctor in time for surgical anastomosis treatment. Unless the patient is elderly, at high risk, or has other contraindications to surgery. After surgery, the joint is braked for four weeks to promote recovery from ligament rupture. After four weeks, you can gradually perform joint flexion and extension exercises and limb muscle strength exercises to restore normal limb flexion and extension, force activities, in order to restore the patient’s normal life and work.
