Relationship Between Quantitative MRI UTE T2* of ACL Autografts and BMI-Normalized Knee Laxity Within the First Year After ACL Reconstruction.

ABSTRACT:

Background

The anterior cruciate ligament reconstruction (ACLR) graft undergoes a remodeling process that affects its structural properties. Ultrashort echo time T_2* (UTE-T_2*) imaging has been instrumental in examining this process. However, more research is needed on the postoperative relationship between UTE-T_2* of the graft and its mechanical properties.

Purpose

To longitudinally examine ACL graft changes after ACLR using UTE-T_2* decay coefficients and knee laxity and explore their relationship.

Study design

Case series; Level of evidence, 4.

Methods

A total of 31 patients who underwent ACLR had magnetic resonance imaging of their knees at 1, 6, and 12 months after surgery using a UTE-T_2* sequence. Bilat
