Non Contact vs. Contact ACL Injuries Interviewer: The ACL, is there a risk for injury during many types of athletic activity? Are there certain sports where athletes are at higher risk for tearing their ACL than others? Interviewee: Yeah, there are. Particularly for a female, the risk in basketball, volleyball and soccer are five times that of men’s sports but it is really common in football and basketball, primarily in men’s sports. Interviewer: Commonly, our patients who ask and we even as orthopedic surgeons, we divide ACL, there is a mechanism by which it is torn into contact, mechanism in noncontact, can you go ahead and just describe what that means? Interviewee: Well, probably the most common is what we call noncontact. When you are running down the court and you plant your foot to cut in a different direction and what happens is actually is your quad muscles contract and do a tremendous load which pulls the lower leg forward and as you are turning, you tear the ACL. A more devastating injury we see occasionally in football where someone hits you from the side, from the outside and your knee goes in—twist where you’ll tear the ligament on the inside of your knee and the ACL deep inside your knee. But I think in our experience probably 75%, most of the tears we seen in sports are isolated ACL tears, noncontact.
