Meniscus tear, for more than half a year, a friend suggested minimally invasive surgery? Is it feasible? How much does the operation cost? Need after operation

I suggest you operate as soon as possible, otherwise the meniscus is broken and can only be removed. Moreover, the wear of the knee joint caused by meniscus rupture will be very serious. This is a minor operation, and you can basically walk normally in about 15-20 days. The cost of the operation is about 15 thousand. After half a year, you will be no different from normal people.
