Knee ligament tears are often classified as Grade 1, Grade 2 and Grade 3. Grade 1 and Grade 2 tears are often partial ligament injuries, which do not require surgery and can be treated conservatively. Conservative treatment can be done by external fixation of the knee joint with a brace or cast, and then regular review of the knee MRI during the fixation period, once every 2-3 weeks, for 2-3 consecutive times, to determine the degree of recovery of the knee ligament tear. At the same time, oral medication can be taken to treat the pain, such as loxoprofen sodium tablets and aminoglutethimide tablets. You can also take oral medications to renew the tendons and bones, such as Pan Long Qi Tablets and Da Qi Li Capsules, which are very helpful for the recovery of torn knee ligaments. Knee ligament tears with knee instability often require surgical treatment.
