Which sesamoid bone is in the knee?
Last Updated:
The patella, also known as the patella, is a sesamoid bone, meaning it is inserted into a tendon. The patella is located at the front of the knee, within the quadriceps femoris tendon, and plays an essential role in the function of the knee joint.
The main function of the patella is to protect the knee joint and reinforce the leverage of the quadriceps tendon during leg extension. This leverage improves the efficiency of the quadriceps muscle, making the action of straightening the leg at the knee more effective.
In anatomical terms, the patella is the largest sesamoid bone in the human body. It is triangular in shape, with an upper base and a lower tip. The back of the patella is covered with cartilage, enabling it to glide smoothly over the femur as the knee bends and straightens.
The patella is essential to knee mobility and stability. It distributes the forces generated by the thigh muscles during movement, while protecting the joint from excessive wear.
However, like any anatomical structure, the patella can be prone to problems such as fractures, dislocations or patellar pain syndromes, often caused by intense physical activity or trauma.
The patella is a sesamoid bone essential to knee function, offering protection and mechanical efficiency to the joint, and playing a key role in everyday movements such as walking, running or jumping.

Answer
The patella is a sesamoid bone of the knee. It protects the knee joint and facilitates movement by improving the leverage of the quadriceps femoris tendon.
