Lateral condyle of femur is one of the two condyles of the femur, or thigh bone, in the human body. The femur is the longest and strongest bone in the body, connecting the hip to the knee. The lateral condyle is the outer part of the femur that articulates with the tibia and the patella (kneecap) to form part of the knee joint.

Structure[edit | edit source]

The lateral condyle is a rounded projection on the distal end of the femur, contributing to the knee joint's structure. It is larger and more prominent than the medial condyle, reflecting the greater weight-bearing role of the outer part of the knee. The surface of the lateral condyle is covered with articular cartilage, facilitating smooth movement within the joint.

The topography of the lateral condyle includes the lateral epicondyle, which serves as an attachment point for ligaments and muscles, including the fibular collateral ligament and part of the biceps femoris muscle. The lateral condyle also features the lateral articular surface, which articulates with the lateral meniscus and the tibia.

Function[edit | edit source]

The primary function of the lateral condyle of the femur is to facilitate movement at the knee joint, allowing for flexion, extension, and slight rotational movements. It plays a crucial role in supporting the body's weight during standing, walking, and running. The lateral condyle works in conjunction with the medial condyle to ensure stability and mobility of the knee.

Clinical Significance[edit | edit source]

Injuries to the lateral condyle can occur due to trauma, such as falls or sports injuries, leading to fractures or ligament tears. Osteoarthritis can also affect the lateral condyle, resulting in pain, stiffness, and reduced mobility of the knee. Treatment options vary depending on the severity of the condition and may include physical therapy, medication, or surgery.
