Lateral Meniscus Posterior Root Repair with Lateral Extra‐articular Tenodesis Significantly Decreased Internal Rotation and Pivot Shift Loading in a Cadaveric Study of Anterior Cruciate Ligament Reconstructed Knees
Key Points
The research aims to evaluate the effectiveness of lateral meniscus posterior root repair and lateral extra-articular tenodesis for knee stability post-ACL reconstruction.
Cadaveric study design assessing knee stability interventions
Included lateral meniscus posterior root repair and anterolateral corner reconstruction
Evaluated internal rotation and pivot shift loading effects
Significant decrease in internal rotation observed
Marked reduction in pivot shift loading factor
Indicates improved knee stabilization with combined surgical techniques
Abstract
Both LMPR repair and anterolateral corner reconstruction are necessary to restore stability in knees with ACL, Kaplan fiber, and LMPR injuries.
