The<unk>  (anterior ligament) is the central portion of the common tendon of the Quadriceps femoris, which is continued from the<unk> to the tuberosity of the tibia.
It is a strong, flat, ligamentous band, about 8 cm. in length, attached, above, to the apex and adjoining margins of the<unk> and the rough depression on its posterior surface; below, to the tuberosity of the tibia; its superficial fibers are continuous over the front of the<unk> with those of the tendon of the Quadriceps femoris.
The medial and lateral portions of the tendon of the Quadriceps pass down on either side of the<unk>  to be inserted into the upper extremity of the tibia on either side of the tuberosity; these portions merge into the capsule, as stated above, forming the medial and lateral<unk>  retinacula.
The posterior surface of the ligamentum patellæ is separated from the synovial membrane of the joint by a large infrapatellar pad of fat, and from the tibia by a bursa.
