Physeal-sparing anterior cruciate ligament reconstruction provides better initial joint biomechanics than complete transphyseal reconstruction in an early adolescent porcine model.

ABSTRACT:

Purpose

The aim of this study was to compare initial joint kinematics and tissue forces following complete transphyseal, partial transphyseal and physeal-sparing anterior cruciate ligament (ACL) reconstruction (ACLR) in an early adolescent porcine model.

Methods

Eighteen early adolescent porcine knees were tested using a six-degree-of-freedom robotic testing system at 40° and 60° of flexion. An 80 N anterior-posterior (AP) force, 120 N compression force and 4 N m varus-valgus torque were applied to the tibia in intact, ACL transected and ACLR states. Complete transphyseal, partial transphyseal, and physeal-sparing surgical techniques were performed (n = 6 legs/technique). Kinematics under applied loads were recorded to assess joint stability and compared across each s
