Increased external rotation at 30 degrees only indicates an isolated PCL injury. Noticed differences at both 30 and 90 degrees indicate combined PCL and PLC injury.
What motions does the ACL prevent?
The cruciate ligaments control the back and forth motion of your knee. The anterior cruciate ligament runs diagonally in the middle of the knee. It prevents the tibia from sliding out in front of the femur, as well as provides rotational stability to the knee.
