Introduction[edit | edit source]
Knee Structure[edit | edit source]
The knee joint include four bones: distal end of the femur, proximal end of the tibia, patella and the proximal part of the fibula. Only the fibula is indirectly involved in the knee joint.
- Prominent lateral and medial condyles are found at the distal end of the femur. Projecting from each condyle is an epicondyle that act as attachment sites for the collateral ligaments. The lateral and medial condyles are separated by the intercondylar notch. [1]
- The proximal end of the tibia terminates in a broad, flat region called the tibial plateau. The intercondylar eminence runs down the midline of the plateau, separating the medial and lateral condyles of the tibia. The two condyles form a flat, broad surface for articulation with the medial and lateral condyles of the femur. [2]
- The patella articulates with the femur to form the patellofemoral joint.
- A enlarged pointed head and small neck form the proximal part of the fibula.
