ACL Tear (2 months) To heal completely?

If you have a complete ACL tear and there are occasional symptoms of buckling or instability, no amount of medication or physiotherapy will CURE it. If and like you said you want to return to sporting activities, ACL Reconstruction would be imperative. Fortunately it is an arthroscopic surgery without any significant surgical morbidity. Return to function takes 3-6 months. Though you are allowed to walk on the same evening after surgery but contact sports are permitted not before 6 months have passed post surgical ACL reconstruction. Usually the patients become almost normal in 3 weeks after surgery, extensive physiotherapy and rehab is required to regain lost muscle strength and Range of motion of the joint. There's a post ACL Recon Knee Rehab protocol which should be followed stringently to get the best results. Kindly see an orthopedic Surgeon who specializes in sports injuries and Arthroscopic surgery.
