The palpable hip bone projections in the front of the body felt when you put your hands on your hips are the posterior inferior iliac spines. At the superior (proximal) end of the tibia, a pair of flattened condyles articulate with the rounded condyles at the distal end of the femur to form the knee joint or tibiofemoral 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. It is known as the groove for popliteus.

Arises below the adductor tubercle of the medial femoral condyle to the medial epicondyle of the tibia. The tibia, or shin bone, spans the lower leg, articulating proximally with the femur and patella at the knee joint, and distally with the tarsal bones, to form the ankle joint. This axis can be identified by drawing a vertical line from the center of the femoral head to the center of a horizontal line across the tibial plateau (the center of the knee joint line). It is characterized by a longitudinal concavity and a transverse convexity, and the distal portion is located outside of the joint capsule. These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges (see Figure 6.51). Arising from the greater trochanter to the ischium. The medial supracondylar line ends at the adductor tubercle, where the adductor magnus attaches. Please note that the mechanical axis of the femur differs from the anatomical axis of the femur (a line running from the center of the greater trochanter, along the femoral shaft, and ending at the center of the knee joint line).
