Term
| Name attachments of ACL & PCL. |
|
Definition

|
|
Term
|
Definition
| ACL prevents femur from post displacement on tib & tib from ant displacement on femur. Largest portion tightens in knee ext. & int. rot. Twist in fibers causes some tightness in all positions. |

Term
|
Definition
| PCL prevents femur from ant displacement on tib & tib from post displacement on femur. Short, thick portion tightens in knee flex. Twist in fibers causes some tightness in all positions. |
