Is it safe to leave the ACL "unrepaired" or will it cause further damage

Question

Assuming just walking, no playing of sports.

Answer 1

Early arthritis is really the only long-term risk as long as he doesn't run, but that depends on how badly it was damaged. Slight tear? Full blown?

But just walking and no athletic activity of any kind? That might be a big assumption (and not much fun at all), but you won't do much further damage your knee.
