How long will rehabilitation after arthroscopic anterior cruciate ligament be?

2-3 months: Intensive therapy to regain range of motion, reduce swelling and then regain strength will last between 2-3 months. Long term strengthening will be necessary, for best results, for up to 1-2 years after surgery. This long term strengthening can be done at home or at the gym.

ACL Rehab: It depends on the type of acl graft used and the technique your surgeon uses. Generally people are in therapy for 3-6 months after surgery. People are usually able to return to sports in the 6-9 month range.
