Knee Bones and Joints

The tibiofemoral joint is a hinge joint, located between the largest bone in the body (the femur) and the larges bone in the lower leg (the tibia.) These two bones are joined together and form a medial and lateral compartment.

The second joint in the knee complex is located between the patella (knee cap) and the femur. The patella glides up and down a groove on the anterior distal aspect of the femur called the patellofemoral joint.

There is also a joint between the small lateral bone of the lower leg (fibula) and the larger tibia.

The osseous joint surface all have articular cartilage that covers the ends of the bones. The articular cartilage has a smooth and shiny surface, which allows the ends of the bones to slide freely over each other.
