Treatment of meniscus and ligament injuries can be non-surgical, such as lower limb immobilization and braking, functional exercises and physical therapy such as ultrasound, together with medication such as non-steroidal anti-inflammatory and analgesic drugs, such as celecoxib, etc.; serious injuries need to be treated by surgical methods, such as arthroscopy of the knee, such as meniscoplasty. 1. If the degree of meniscus and ligament injury is mild and does not cause obvious joint instability or obvious meniscus tear, it is usually treated by non-surgical methods, and the knee joint is immobilized at an early stage, which can be treated by plaster or brace. Avoid weight bearing and strenuous exercise, with functional exercises such as straight leg raising, etc., can also be used with physical therapy such as ultrasound, while complying with the doctor’s instructions to use non-steroidal anti-inflammatory analgesic drugs such as celecoxib. 2. Meniscus and ligament damage to a more serious degree, such as ligament rupture or most of the tear, or the meniscus is obviously torn at the third degree of injury generally need to be treated by surgical methods, at present, more in the knee arthroscopy for ligament reconstruction, repair, and meniscus plasty or suture surgery, and so on. Meniscus and ligament injuries need to go to the hospital in a timely manner, to clarify the degree of injury, and under the guidance of the doctor combined with the patient’s specific condition to take the appropriate treatment program.
