What to do if knee ligament is injured

Knee ligament injuries must be treated scientifically. Conservative treatment can be used, such as fixation with plaster. Especially for some ruptures, they must be repaired as soon as possible. If there are severe tears, surgery and repair treatment are required.

1. Medial collateral ligament injury: Sprain or partial rupture (deep layer) of the medial collateral ligament can be treated conservatively with long-leg tubular plaster fixation for 4-6 weeks. Complete rupture should be repaired as soon as possible. If there is meniscus injury and anterior cruciate ligament injury, they should also be treated at the same time during surgery.

2. Injury to the lateral collateral ligament: Patients with rupture of the lateral collateral ligament should undergo immediate surgical repair.

3. Anterior cruciate ligament injury: Any anterior cruciate ligament rupture that is less than 2 weeks old should be sutured surgically. If the ligament is broken, it is best to transplant a tendon to enhance the stability of the cruciate ligament. Generally, the middle 1/3 of the patellar ligament is selected as the transplant material. For partial rupture, the broken part can be sutured and then immobilized with plaster for 4-6 weeks. Currently, it is advocated to perform ligament suture surgery under arthroscopy.

4. There has been controversy in the past about whether the ruptured posterior cruciate ligament should be sutured. Current opinions tend to favor early repair under arthroscopy.
