| Medial (tibial) collateral ligament (MCL) |
|
Definition
| thickening of the fibrous capsule on the medial side to provide medial support of the knee |
|
|
Term
| lateral (fibular) collateral (LCL) |
|
Definition
| thickening of the fibrous capsule on the lateral side to provice lateral support of the knee |
|
|
Term
|
Definition
| ligament located within the knee joint; starts from the tibia and runs upward, backward and lateral to attach to the medial side of the lateral condyle of the femur to prevent anterior movement of the tibia (femur considered fixed bone) |

Definition
| ligament located within knee joint; starts from tibia and runs upward, forward and medial to attach to lateral side of the medial condyle of the femur to prevent posterior movement of the tibia (femur considered fixed bone) |

|
Term
| medial and lateral menisci |
|
Definition
| C-shaped fibrocartilage rings between femur and tibia |
|
|
Term
| explain the "screw-home mechanism" |
|
Definition
when the knee fully extends, the femur medially rotates on the tibia to line up on top of it, allowing the femur to rest on top of the tibia and knee extension can be maintained with little muscular support
NOTE: the ACL (anterior cruciate ligament) becomes taunt and provides the most integrity to this joint in this sposition |
