the two primary articulations of the knee joint are enclosed within a __ __ __
single joint capsule
what articulation allows the knee to be classified as a hinge joint?
the articulation of the tibia with the femur
what structures make up the tibiofemoral joint of the knee?
the medial and lateral condyles of the distal femur
the medial and lateral condyles of the proximal tibia
what structure makes up the proximal surface of the tibiofemoral joint?
the medial and lateral condyles of the distal femur
what structure makes up the distal surface of the tibiofemoral joint?
the medial and lateral condyles of the proximal tibia
within the tibiofemoral joint of the knee, the medial and lateral condyles of the distal femur are __ in shape and the medial and lateral condyles of the proximal tibia are __ in shape
convex; concave
what structures is the patellofemoral joint of the knee formed by?
patella
trochlear groove of the femur
within the patellofemoral joint of the knee, the patella is __ in shape and the trochlear groove of the femur is __ in shape
convex; concave
the patella slides __ during knee extension and __ during knee flexion
superiorly; inferiorly
patella __ and __ also occur as it moves inferiorly and superiorly during knee flexion and extension, respectively.
rotation and tilting
