Surgical Treatment of a Rare Isolated Bilateral Agenesis of Anterior and Posterior Cruciate Ligaments

الملخص EN

The isolated bilateral agenesis of both cruciate ligaments is a rare congenital disorder.

A 17-year-old male came to our attention due to an alteration in gait pattern, pain, and tendency to walk on the forefoot with his knee flexed.

The patient did not recall previous injuries.

Upon physical examination anterior and posterior chronic instability were observed.

Radiographic examination of both knees showed hypoplasia of the tibial eminence, a hypoplastic lateral femoral condyle, and a narrow intercondylar notch.

MRI brought to light a bilateral agenesis of both posterior cruciate ligaments.

Arthroscopic evaluation confirmed bilateral isolated agenesis of both cruciate ligaments.

We recommended a rehabilitation program to prepare the patient for the arthroscopic construction of both cruciate ligaments.
