The Mysterious Function of the Kneecap

The video explores the anatomy and function of the kneecap, or patella, highlighting its role as a sesamoid bone that enhances the mechanical advantage of the quadriceps muscles. Through cadaver dissections and whiteboard explanations, the video demonstrates how the patella increases leverage, making the quadriceps 30% stronger. It also discusses the patella's sliding and gliding motion, which changes its mechanical advantage based on joint angles, particularly between 20 to 60 degrees of knee flexion.
