The PCL Index Is Correlated With the Control of Rotational Kinematics That Is Achieved After Anatomic Anterior Cruciate Ligament Reconstruction

Abstract

This study provides evidence regarding the interplay between restoration of the native ACL's anatomy and the PCL's appearance and suggests that the effective restoration of tibiofemoral alignment after ACLR that is reflected in the PCL index translates into better functional outcomes as measured by tibial rotation during pivoting activities.

Hip and Knee Kinematics and Kinetics During Landing Tasks After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-Analysis

“…39 Another article 40 was removed for publishing only limb symmetry scores as opposed to data for individual limbs. Eight additional articles [41][42][43][44][45][46][47][48] were removed because the authors did not report means SDs or reply to requests for data. Therefore, 20 articles 39,49-67 met the selection criteria and were included in the analysis (Figure 1).…”

Motion Task Selection for Kinematic Evaluation After Anterior Cruciate Ligament Reconstruction: A Systematic Review

“…41,50 The remaining 2 studies reported a correlation between posterior cruciate ligament index and tibial rotation in the ACLR knee and a correlation between passive knee laxity and tibial rotation. 65,74,75…”

Spatial Change of Cruciate Ligaments in Rat Embryo Knee Joint by Three-Dimensional Reconstruction

“…Both ligaments are not completely straight, but the buckling of the PCL is increased when the ACL is ruptured. [ 12 , 13 ] The mean PCL angle is 123° in the normal human adult, but this decreases to 106° in the ACL-deficient knee. [ 14 ] The PCL angle itself changes with growth.…”
