Lateral patellar retinaculum

The lateral patellar retinaculum is a fibrous expansion comprising of superficial and deep layers.

Gross anatomy

The superficial layer originates from the lowest fibres of the iliotibial band and from an extension of vastus lateralis fascia. The deep layer is comprised of the lateral patellofemoral ligament, patellotibial band and transverse ligament.

It thickens as it inserts onto the lateral border of the patella, quadriceps tendon and patellar ligament. From this insertion, it extends posteriorly to blend with the lateral margin of the knee capsule and inferior surface of the lateral tibial condyle 1,2.
