Makata, only a doctor can tell you if you need surgery. As I said earlier, recovery usually involves RICE, and it will take as long as your body needs. The pain and swelling will go down. At that time, you might consider physical therapy to help strengthen your leg muscles, and further reduce inflammation.
My son had the ACL repair surgery only to blow out his new ACL within a year, again playing football -- he was on a football scholarship. That was about 10 years go.
