Reinserción simultánea de raíz posterior de menisco externo y anterior del interno con plastia de ligamento cruzado anterior asociada

Abstract

Posterior meniscal roots lesion can appear in 10-12% anterior cruciate ligament (ACL) tears, but the frequency of associated injuries of anterior roots still remains unkown, due to its lower incidence. No cases about concomitant anterior and posterior root lesions have been published to the moment.

The case of a 17-year-old woman is presented, with associated posterior lateral root (PLRT), anterior medial root (AMRT) and anterior cruciate ligament tears, with the AMRT going unnoticed on magnetic resonance imaging (MRI) study. ACL was reconstructed with outside-in technique; PLRT was reinserted with transosseous technique and AMRT with a 5-mm suture anchor. After 18 months, the patient keeps asymptomatic and practising sports.

It is important to detect the posterior root lesions due to its biomechanic consequences, similar to those that occur after total meniscectomy, although it may be difficult because they can go unnoticed on MRI study. Transosseuous reinsertion of PLRT and suture anchor reinsertion of AMRT provide good results in the medium term.
