Key result
A 17-year-old male with rare isolated bilateral agenesis of both cruciate ligaments presented with chronic instability and was recommended for arthroscopic reconstruction.
Case Report (n=1)
Describes a rare congenital presentation of isolated bilateral agenesis of both cruciate ligaments and its diagnostic workup.
Recognize congenital bilateral cruciate agenesis in adolescents with instability; leaves optimal reconstruction and outcomes open.
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.

Cerulli et al. (2014) conducted a case report in Isolated bilateral agenesis of anterior and posterior cruciate ligaments (n=1). Arthroscopic construction of both cruciate ligaments was evaluated. A 17-year-old male with rare isolated bilateral agenesis of both cruciate ligaments presented with chronic instability and was recommended for arthroscopic reconstruction.
