🦵 ACLR Surgical Pearl (MRI-based evidence): Protecting the AHLM in remnant-preserving technique
In a retrospective MRI study of 80 remnant-preserving ACL reconstructions, the tibial tunnel was sometimes extremely close to the anterior horn of the lateral meniscus—even 0mm (tangential) in 5% (axial) and 3.8% (coronal)—yet no MRI signs of meniscal injury,
deformation, complex tear, or extrusion were observed.
âś… Take-home: When performing RP-ACLR, meticulous guidewire positioning so it exits through the center of the remnant may help avoid AHLM injury.
📌 Mean nearest distances: ~3.56 mm (axial) and ~3.60 mm (coronal) with excellent measurement reliability.
