Maybe. Plenty of players have done their ACL's and come back as strong as ever. With the right treatment and rehab I don't know if it is necessarily such a debilitating issue as it had been in the past. Now, issues like what Ledley had are things you don't recover from. Degenerative knee issues just don't get better, but ligament treatments have come a very long way.He's had ACL on BOTH knees.
I'd say thats a problem.
Since his last major knee issue he's played 82 games and scored 34 goals.
