Bones
These three bones comprise the knee joint.
What are the femur, tibia, and patella?
These are the four main ligaments of the knee.
What are the anterior and posterior cruciate ligaments and the medial and lateral collateral ligaments?
These four muscles make up the quadriceps.
What are rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis oblique?
This is the difference between subluxation and dislocation.
What is partial vs complete displacement?
These bony landmarks allow for passive stability of the patella on femur.
What are the femoral condyles and patellar facets?
This passive structure in the knee provides stability and shock absorption within the joint.
What is the meniscus?
An imbalance between these two muscles is to blame if the patella were to dislocate laterally, a common knee pathology.
What are vastus lateralis and vastus medialis?
Females are more at risk for patellar dislocations for this reason.
What is a wider pelvis?
These are the anatomical terms for bow legs and knock knees, two common anatomical variations at the knee.
What are genu varum and genu valgum?
The anterior cruciate ligament (ACL) resists motion in this direction.
What is anterior tibial shear?
These 7 muscles are flexors of the knee.
What are the biceps femoris, semitendinosus, semimembranosus, gastrocnemius, sartorius, gracilis, and popliteus?
The patella serves these functions as part of the quadriceps tendon.
What is creating a longer moment arm and providing mechanical advantage?
