Tibial Plateau Anatomy

The lateral plateau the medial plateau along with the intercondylar eminence. Anatomy consist of medial and lateral plateau medial larger medial lower concave medial bone harder thus less likely to fracture lateral higher convex lateral cartilage thicker 3 vs.

Tibial Plateau Fractures

Early detection and appropriate treatment of these fractures are critical for minimizing patient disability and reducing the risk of documented complications particularly posttraumatic arthritis.

Tibial plateau anatomy. Normally the medial tibial plateau protrudes anteriorly 1 cm beyond the medial femoral condyle when the knee is flexed to 90 figure 20 20. Concave articular surfaces of the oval shaped medial and circular shaped lateral tibial condyles medial and lateral tibial plateaus. Lateral plateau is covered by meniscus tolerates incongruity better than medial plateau.

4 mm lateral medial. The lateral plateau is smaller as well as convex while the medial plateau is larger and slightly concave. The tibial plateau is composed of two parts.

Lateral plateau more commonly fractures. Medial plateau larger than lateral medial is concave in sagittal plane golf tee lateral is convex more proximal golf ball creates 3 o of varus proximal tibia. Fractures of the plateau affect knee alignment stability and motion.

A fall from a height or a hit to the thigh can drive the femur. Normal posterior slope 10 o. The tibial plateau is an important weight bearing part of the body that connects the thighbone femur to the shinbone via ligaments.

Central non articular intercondylar area. Located between the condyles is a region called the intercondylar eminence this projects upwards on either side as the medial and lateral intercondylar tubercles. The tibial plateau is one of the most critical loadbearing areas in the human body.

83 this step off is lost when there is a posterior sag of the tibia associated with injury to the pcl and other secondary restraints to posterior translation of the tibia. The condyles form a flat surface known as the tibial plateau. The tibial plateau is made up of three osseous structures.

This structure articulates with the femoral condyles to form the key articulation of the knee joint.
