Repair of the Posterior Lateral Meniscal Root Tear: Suture Anchor Fixation Through the Outside-In Anterior Cruciate Ligament Reconstruction Femoral Tunnel

Posterior lateral meniscus root tears are defined as tears that occur within 9 mm of the posterior lateral meniscus insertion or as avulsions of the insertion. If root tears are left unrepaired, functional alterations and early degenerative changes occur in the affected compartment. Several surgical techniques have been described to reattach the posterior horn of the lateral meniscus, including transtibial pull-out technique and side-to-side repair technique. This surgical technique reports an alternative way to repair posterior lateral meniscus root tears that are associated with or without an anterior cruciate ligament graft tear. The technique involves the placement of a suture anchor on the lateral meniscus root footprint through the outside-in anterior cruciate ligament femoral tunnel, which minimizes the possibility of iatrogenic lesions and facilitates repair.
