The patellar region sits on the front of the knee. The kneecap (patella) is located at the anterior surface of the knee, embedded in the quadriceps tendon and gliding in the patellofemoral groove of the femur as the knee extends and flexes. This front placement is what defines the patellar region and makes it a key part of the knee’s extensor mechanism, boosting leverage during leg extension. The elbow, ankle, and shoulder are different joints and do not involve the patella.
