1️⃣ Medial Quadriceps Tendon Femoral Ligament

  • The Medial Quadriceps Tendon Femoral Ligament (MQTFL) At the axial level of the insertion of the adductor magnus tendon (AMT) on the adductor tubercle, we can visualize the vastus medialis obliquus muscle, adductor magnus tendon, and adductor tubercle. 
  • Proximal to the MPFL and patella are oblique ligamentous fibers extending to insert into the distal quadriceps, termed the medial quadriceps tendon femoral ligament (MQTFL), outlined by the purple dotted line.
  • Role of the MQTFL The MQTFL may contribute to patellar stability, particularly in full knee extension.
  • Surgical Reconstruction
    With modern surgical techniques, it is now possible to reconstruct the MPFL, the MQTFL, or both of these proximal medial patellar restraints.
