Other Terms: Patellar Tendon, Quadriceps tendon, Quadriceps femoris tendon
The quadriceps tendon is compound tendon formed by the junction of the rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis muscles. This strong tendon, second only in size to the tendocalcaneus, arises above the patella as the four muscles of the quadriceps converge in a broad aponeurosis to engulf the sesamoid patella. After attaching to and surrounding all but the posterior articular surface of the patella, the tendon continues below the patella as a strong, thick band to insert into the tibial tuberosity. The portion of the tendon between the patella and the tibial tuberosity is named the patellar ligament.
