###Human: Is it advisable to use a brace for ACL fracture and play rugby? ###Assistant: Hello. I have read your concern. It will not be comfortable for you to play with an ACL brace if you have grade 3 ACL tear as twisting and turning will not be quick and comfortable to the level game demands. If you have kind of grade 2 then you can strengthen and then have a support and play (again depends on the level of involvement of the fibers, more than 50 % then you should consider surgical reconstruction option as you will always be at risk of progressing it to complete tear. In either case, start your rehabilitation exercises. Can use brace while training. There is a risk of loading certain areas of the joint leading to early bony erosion. It may not be a very good idea.
