Lateral superior genicular artery

The lateral superior genicular artery is a branch of the popliteal artery that supplies blood to the knee joint and surrounding structures. It is one of the several genicular arteries that contribute to the vascular network around the knee, known as the genicular anastomosis.

Anatomy

The lateral superior genicular artery arises from the popliteal artery just above the knee joint. It travels laterally, passing deep to the biceps femoris muscle and over the lateral condyle of the femur. It then divides into several branches that supply the lateral aspect of the knee, including the lateral meniscus, the lateral collateral ligament, and the synovial membrane of the knee joint.

Function

The primary function of the lateral superior genicular artery is to provide oxygenated blood to the structures of the lateral knee. It plays a crucial role in the genicular anastomosis, which ensures adequate blood supply to the knee joint, especially during movements that may compress other arteries.

Clinical Significance

Injuries to the lateral superior genicular artery can occur due to trauma or surgical procedures involving the knee. Damage to this artery can lead to compromised blood flow to the knee structures, potentially resulting in ischemia or delayed healing. Understanding the anatomy of this artery is important for orthopedic surgeons and other healthcare professionals involved in knee surgeries.
