Summary

This study tested whether the usual method of placing ACL reconstruction tunnels at the center of the natural ligament attachments actually keeps the new ligament taut (isometric) throughout knee motion. Thirty healthy volunteers had their knees scanned with a special 4D scanner while bending. The goal was to measure how the distance between the attachment points changes, to help design better surgical planning software.
