Effect of Nearly Isometric ACL Reconstruction on Graft-Tunnel Motion: A Quantitative Clinical Study.

ABSTRACT:

Background

In anterior cruciate ligament (ACL) reconstruction, minimizing the graft-tunnel motion (GTM) will promote graft-to-bone healing and avoid graft loosening or tearing as well as potential bone tunnel enlargement. A nearly isometric state of the graft can be achieved by placing the tunnel properly to theoretically gain better graft-to-bone healing. However, little clinical evidence is available to quantify the relation between GTM and tunnel position.

Purpose

To find the proper zones for the femoral and tibial tunnel apertures that minimize the GTM, referred to as the "nearly isometric zone," through use of intraoperative GTM measurement and 3-dimensional computed tomography (3D-CT).

Study design

Cross-sectional study; Level of evidence, 3.
