The patella (pl.: patellae or patellas), also known as the kneecap, is a flat, rounded triangular bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint.
It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. [1] The capsule consists of an inner synovial membrane , and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly.
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
Kneecapping is a form of malicious wounding, often as torture, in which the victim is injured in the knee.The injury is typically inflicted by a low-velocity gunshot to the knee pit with a handgun.
Often, these bones form in response to strain, [4] or can be present as a normal variant. The patella is the largest sesamoid bone in the body. Sesamoids act like pulleys , providing a smooth surface for tendons to slide over, increasing the tendon's ability to transmit muscular forces .
Furthermore, studies have found knee pain to be negatively associated with health-related quality of life, and an increase in knee pain to be associated with a reduction in patient-reported quality of life, as compared to those with no or stable knee pain, even in the relatively younger middle-aged population.

DETROIT — Three years to the day since Dan Campbell stood behind a lectern talking about how his Detroit team would be “biting kneecaps,” Lions fans stood in the corner of Ford Field and ...
The top of the patella attaches to the quadriceps muscle via the quadriceps tendon, [2] the middle to the vastus medialis obliquus and vastus lateralis muscles, and the bottom to the head of the tibia (tibial tuberosity) via the patellar tendon, which is a continuation of the quadriceps femoris tendon.
