The lateral femoral condyle is located on the upper lateral side of the knee joint and is the main component of the femoral articular surface of the knee joint. The lateral side of the lateral condyle is attached to the lateral collateral ligament, which is connected to the fibular tuberosity and plays an important role in the stability of the left and right side of the knee joint. The medial side of the lateral condyle is where the cruciate ligament stops and plays a major role in the anterior and posterior stability of the knee joint. Between the lateral femoral condyle and the tibial plateau, there is a lateral meniscus, which acts as a cushion for the joint and prevents direct cartilage wear and tear, which can cause arthritis. Once a fracture of the lateral femoral condyle occurs, surgical repositioning and internal fixation is usually required to maintain the stability of the fracture end and to restore the joint surface and avoid ligamentous laxity that can cause joint instability.
