The patellar ligament (anterior ligament) is the distal portion of the common tendon of the quadriceps femoris, which is continued from the patella to the tibial tuberosity.

Structure[edit]

It is a strong, flat, ligament, about 5 cm in length, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the Quadriceps femoris.

The medial and lateral portions of the quadriceps tendon pass down on either side of the patella 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 patellar retinacula.

The posterior surface of the patellar ligament is separated from the synovial membrane of the joint by a large infrapatellar pad of fat, and from the tibia by a bursa.

It is also sometimes called the "patellar tendon".[1]

Clinical significance[edit]

It can be injured in a patellar tendon rupture.

It can be used as a tissue source in the repair of other ligaments.[2]
