The outlook is good. Researchers recently observed patients who had ACL surgery followed by five weeks of wearing either a cast or a brace. Patients also had six to eight months of therapy to get their agility and strength back. Three years after surgery, these patients did as well on tests of balance as people who didn't have ACL problems. Patients who had ACL surgery had slightly slower reaction times, but in general their balance was just as good.
Ask your doctor or physical therapist about ways to manage your knee after surgery to ensure a full recovery.
