In humans and other primates, the knee joins the thigh with the leg and consists of two joints: one between the femur and tibia (tibiofemoral joint), and one between the femur and patella (patellofemoral joint).
The knee is the joint that links 4 of the upper and lower bones of the leg, which are called the femur, tibia, fibula and the patella.
