Ligament injuries of the knee generally require braking, fixation, and rest for 4-6 weeks, and depending on the recovery situation, decide when you can stand and walk normally. As for running, it is generally recommended to run for more than half a year. Premature running can easily lead to aggravation of ligament injuries, which can lead to re-injury of the ligaments and produce negative consequences. Ligament injuries in the knee include injuries to the medial and lateral collateral ligaments, the joint capsule and the cruciate ligament, which are all common knee ligament injuries. Depending on the condition, if the knee is stable, it can be treated conservatively, usually with braking, immobilization, and rest for six weeks to gradually restore normal function. If you want to increase the load further, it often takes three months to six months, and if there is a ligament injury that requires surgery, it usually takes more than six months to be able to run.
