Which artery supplies blood to the knee joint?

1. Radial

2. Popliteal

3. Ulnar

4. Posterior tibial

The correct answer is: Popliteal

The popliteal artery is the primary vessel responsible for supplying blood to the knee joint. This artery is located at the back of the knee and branches off from the femoral artery. As it travels down the leg, it further divides into several important branches, including the anterior and posterior tibial arteries, which help supply blood to the lower leg and foot. Because of its anatomical position and function, the popliteal artery plays a crucial role in delivering oxygenated blood to the structures surrounding the knee, including the ligaments, tendons, muscles, and other tissues associated with joint movement and stability. Understanding this artery's role is essential for massage therapists and other practitioners who need to know the vascular supply relevant to the areas they are treating.
