Patella
The patella, also known as the kneecap, is a flat, rounded triangular bone. It articulates with the femur and covers and protects the anterior articular surface of the knee joint. It is attached to the tendon of the quadriceps femoris muscle, which contracts to extend the knee.
About Patella in brief
The patella, also known as the kneecap, is a flat, rounded triangular bone. It articulates with the femur and covers and protects the anterior articular surface of the knee joint. In humans, it is the largest sesamoid bone in the body. It is attached to the tendon of the quadriceps femoris muscle, which contracts to extend the knee. Patellar dislocations occur with significant regularity, particularly in young female athletes. It involves sliding out of its position on the knee, most often laterally, and can be associated with extremely intense pain and swelling.
The patellas are among the thickest in the human body, due to the great stress on the patellofemoral joint during resisted knee flexion. It can be tracked back into the proper position on its own by using the Insall-Salvati ratio on lateral X-rays, divided by the length of the tendon, and calculated as patellar baja on lateral x-rays. An unusually small patellA baja is a low-riding patelli that develops out of and out of the joint, and may result in extensor dysfunction.
