- The femur is the bone of the thigh.
- The femur articulates:
- with the acetabulum of the pelvic bone proximally, forming the hip (femoroacetabular) joint.
- with the tibia distally, forming the knee (tibiofemoral) joint.
- with the patella anteriorly, forming the patellofemoral joint.
NOTE:
- Seven muscles attach onto the linea aspera of the posterior femur (all three “adductor” muscles, all three “vasti” muscles, and the short head of biceps femoris).
- Note the curve in the shaft of the femur that is visible from the lateral and medial views.
