Abstract
Lateral meniscus posterior root tears (LMPRTs) are estimated to occur in 7% to 12% of anterior cruciate ligament (ACL)-injured knees. This topic is of great interest because of their biomechanical consequences in terms of interruption of hoop stress distribution. If left unrepaired, the corresponding compartment is exposed to unfavorable contact dynamics, similar to those resulting from a total meniscectomy. This Technical Note describes a transtibial LMPRT repair using a Knee Scorpion and an 18-gauge spinal needle. It is a reproducible arthroscopic LMPR reinsertion technique combined with concomitant standard ACL + anterolateral ligament reconstruction with hamstring tendons and it describes how to safely avoid damage to root traction sutures during the ACL independent tibial tunnel drilling.
