Final answer:
The knee's anterior aspect includes the patella and the structures that form the femoropatellar joint, which is situated at the front of the knee joint.
Step-by-step explanation:
The body part located on the anterior aspect of the knee is the knee (anterior aspect) itself, specifically the area encompassing the patella (kneecap) and the structures surrounding it. The patella sits on the front of the knee and forms part of the femoropatellar joint, where it articulates with the distal end of the femur.
This setup aids in protecting the tendon of the quadriceps femoris muscle and facilitates smooth movement of the knee joint during flexion and extension. The patella is a triangular bone that lies in the tendon of the quadriceps femoris muscle on the anterior thigh. Its main function is to protect the tendon from rubbing against the distal femur during knee movement.
