It takes only one month for normal treatment of fracture, and one month for ligament injury. It should be fine in about three months. However, if drugs are not used to help callus formation during the operation, it is hard to say, and it may take six months to a year to get better. So is the ligament. The doctor not only lets you rest, but also exercises. There is no better finished drug on the market. In addition, the regeneration ability of ligament is weak, and it can only rely on drugs to help it repair and grow.
I suggest you find a local Chinese medicine teacher who has the ability to prepare for trauma treatment by himself. Otherwise, it will be difficult for you to get better soon. More common sense can be found in Baidu space.
