# BIOMECHANICS OF ANTERIOR CRUCIATE REPAIR

> **NIH NIH R01** · UNIVERSITY OF MINNESOTA · 1987 · $88,312

## Abstract

The goal of the proposed research is to better understand the mechanical
factors in surgical repair procedures for chronic anterolateral
insufficiency of the knee, for which the repair requires an anterior
cruciate substitute to be established.  Experiments will be run on cadaver
knee specimens in which ligament forces will by measured by buckle force
transducers on the four major knee ligaments, and a six degree-of-freedom
goniometer system will be used to measure 3-dimensional knee motion, when
the knee is subjected to a wide variety of external load directions.
Normal knees, knees with a simulated anterolateral injury, and knees
repaired by one of eight procedures will be tested in an identical manner.
Theoretical ligament lengths, and hence, loaded ligament states, will be
predicted using already developed theoretical knee models, with the
measured 3-D motion as input.  The influence of repair insertion location
will be studied both theoretically and experimentally.  The normal and
repaired knees will be compared on the basis of anterior cruciate or
substitute force magnitude, joint laxity, and load sharing by the other
ligaments.
