The femur, thigh bone is present in between the hip joint and the knee joint. This ball and socket articulation is what forms the hip joint. The interaction of these three bones requires numerous ligaments to prevent disarticulation (separation of the bones that interact at their joint). In general, we think of the hip joint as the place where the femur of the thigh articulates with the pelvis, one bone connected to the other. Distally it articulates with the ulnar notch of the radius and with an articular disk that separates it from the carpal bones. Attached to the fovea of the femoral head and the center of the acetabulum. The knee joint is a relatively unstable hinge joint formed by the interaction of three bones: femoral condyles articulate with the tibial plateau (tibiofemoral joint) and the patella (patellofemoral joint).
