The lateral retinaculum is the fibrous tissue on the lateral (outer) side of the kneecap (patella). The kneecap has both a medial (on the inner aspect) and a lateral (on the outer side) retinaculum, and these help to support the kneecap in its position in relation to the femur bone underneath it.

(medial retinaculum), the second layer being intermediate (the Medial Collateral Ligament (MCL), the Posterior Oblique Ligament (POL) and the Medial Patellofemoral Ligament (MPFL)), and the third layer being the deepest (the deep part of the MCL and the joint capsule).
What does the medial retinaculum do?
The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella. It plays important roles in the formation of the fibrous capsule of the knee and in the extension of the knee joint.

How serious is an MPFL tear?
It is a chronic state where the medial patellofemoral ligament does not function properly because of the injury, such as a knee dislocation, or sustained trauma. MPFL insufficiency or incompetent MPFL can lead to repeated patellar dislocations, pain, stiffness and limited range of motion.
How painful is MPFL surgery?
