Does the second stage of femoral head necrosis need surgery? How should I treat it?

The second stage does not require surgery, and the surgery is more destructive. It's best not to have surgery unless absolutely necessary. My neighbor is also in the second phase. He treated it with the femoral head of Lao Fu's family. Now he feels better and better every day. It seems that he is still cooperating with the method of "enlightening" the governor. I suggest you find relevant information to understand. I hope it helps you.
