In human anatomy, the quadriceps tendon, also known as the patellar tendon, allows the quadriceps femoris muscles (rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius) to converge on the superior aspects of the patella on the anterior of the thigh, which continues as the patellar ligament. A tendon connects muscle to bone, while a ligament connects bone to bone. The quadriceps tendon works with the quadriceps to extend the leg.
