Is there a way to strengthen my ankle bone?

In the past I've had a serious of bad things happen to my ankle such as tissue damage, ripped and damaged ligaments etc, basically everything except break it. I've now done it again and have a removable cast and I am on crutches.I'm not looking to break it or anything. I'm not sure what to do about it, is it possible to make it better by having surgery to correct it because the bone/ankle is so weak? I don't know what to do because the doctors always say the same thing and it never fixes it long term.

Rehab.. You need to see a physical therapist to get strengthening exercises for the muscle in that area.
