Knee anatomy
The knee joint is made up of two parts. The part of the knee between the end of the thigh bone (femur) and the top of the shin bone (tibia) is called the tibiofemoral joint. The patellofemoral joint is between the end of the thigh bone (femur) and the kneecap (patella).
Hip anatomy
The hip joint (or acetabulofemoral joint) is where the head of the femur (thighbone) fits into the rounded socket of the pelvis, which is called the acetabulum.
