You will need to keep in mind that rehab means intense rehab 30min+ per day up to 6 days per week to maintain the stability needed in the knee to be able to perform at a high level in football. Athletes can return to sport without significant repairs so long as their rehab is up to par. If you are not willing to make the rehab commitment, then yes, perhaps the surgery would suffice. However, either route will result in surgery. The knee will probably require further support during play with a knee brace to prevent buckling etc.
