How difficult is it to recover from a torn acl?

Hard Work: 80% of the outcome is dependent on good post-op therapy. Early active range of motion, weight-bearing as tolerated usually at first. Strengthening with closed chain exercises can start within the second month. By 4 months, it is possible to return to competitive sports if the therapy effort has restored 80% of thigh strength. Surgery takes 2 hrs., and is outpatient usually.
