The femur is the large bone in the thigh and attaches by ligaments and a capsule to the tibia, the large bone below the knee commonly referred to as the shin bone. Next to the tibia is the fibula, which runs parallel to the tibia on the outside of the leg. The patella, commonly called the knee cap, is embedded in the quadriceps and patellar tendon which articulates with the front of the femur, forming the patellofemoral joint (Figure 1).
