Surgical Factors
One of the most important aspects of ACL surgery success is how well the graft is positioned inside the knee joint. Not every surgical procedure is performed with the same degree of precision, and there are variables that can lead to problems if the new ACL is not properly positioned. The graft must restore the function of the normal ligament, therefore it must be positioned in a similar fashion to the normal ligament.
Inaccurate positioning of the graft can lead to abnormal mechanics of the joint and an increased chance of re-injury.
Recovery From Surgery
Proper rehabilitation after ACL surgery is critically important to the success of the reconstructive surgery. Not only must the new graft become a part of your knee, a process called graft incorporation, but you need to restore normal muscle strength to ensure the knee is well protected.
Patient Factors
There are some aspects of ACL surgery and the risk of re-tear that you can't do much about. For example, female athletes have a higher chance of re-tear of their ACL after reconstructive surgery. In addition, younger athletes are at higher risk for re-injury. Women under the age of 25 have been shown to have a particularly higher chance of re-tear of their ACL than other athletes
also throw in what position a player plays and how they play it....
If the surgery was done properly, healed well (no crazy scar tissue/infections etc), and they play the game smart (think Gore) IMO I don't think you can just say that a player recovering from an ACL is 6x higher across the board.

I'll just add that - the study cited averages the individual stats - and makes a prediction. Each individual can't be pigeon holed into a prediction since every situation is different. Jimmy is a QB that's in a protected class when he drops to pass vs a Richarch Sherman that is always exposed to potential collisions every play. The rules protect Jimmy, not so much the
shermans of the world.
Good OLine play, good surrounding players also factor into Jimmy's risk of re-injury. Ultimately, I don't think - for a QB - re-injury to the knee is something you seriously consider *if* you have a good team. If your team has a terrible OLine and a terrible run game - now I"m going to be very concerned with Jimmy's potential reinjury.
