Quadriceps Tendon Anatomy

Collectively the quadriceps femoris muscle group act as the main extensors of the leg at the knee joint. In human anatomy the quadriceps 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.

Quadriceps Femoris Muscle Wikipedia

At the top of the quadriceps tendon is the quadriceps muscle.

Quadriceps tendon anatomy. At the top of the patella the quadriceps tendon is attached. The quadriceps tendon is a thick tendon extending to the patella made up of contributions from all four quadriceps muscles. The rectus femoris muscle also flexes the thigh at the hip joint and can simultaneously extend the knee whilst also flexing the hip.

Quadriceps tendon rupture anatomy biomechanics figure 1. The tendon is broad based and has a trilaminar depth with fat between the tendon planes. The quadriceps muscle is the large muscle on the front of the thigh.

The quadriceps tendon is the tendinous confluence approximately 3cm proximal to the patella of the vastus lateralis medialis longus and obliquus rectus femoris vastus intermedius and articularis genu. It classically has a trilaminar structure. A tendon connects muscle to bone while a ligament connects bone to bone.

It continues distal to the patella as the patellar tendon. Frontal view of normal patellar tendon and extensor mechanism.
