Where does the rectus femoris muscle insert?

The rectus femoris muscle inserts into the quadriceps tendon, which then attaches to the tibial tuberosity. This insertion point is significant because it plays a crucial role in the function of the quadriceps group, particularly in extending the knee. The rectus femoris is one of the four muscles that make up the quadriceps femoris muscle group, and it is unique because it also crosses the hip joint, contributing to hip flexion in addition to knee extension. Understanding this insertion helps in grasping the biomechanics of leg movement and the importance of the quadriceps in various sports and activities. The insertion at the tibial tuberosity is also clinically relevant, as it is often associated with conditions such as Osgood-Schlatter disease in adolescents.
