Sir after ACL surgery in my legt knee my leg is now zero strength left cuz my quadriceps are completely vanished. Now I am walking with walker without touching the operated leg. I have zero control over my knee. It feels to be a 30kg bag hanging on my left leg. Sir pls suggest How can I regain my original strength n able 2 lift n walk by self. Hoe long time it will take. I am in a state of mental worries cuz I am a sports man. I was running 7 to 8 kms. Daily before this mishap. So can I able 2 back 2 track again if yes then within how many months.
