Diagnostics Knee Arthrometer for Detecting Anterior Cruciate Ligament (ACL) Structural Changes

Technology Benefits

Real time continuous, force-deformation, display and recording Direct measurement of the relative location of femur and tibial tuberosity to eliminate displacement errors that can result from soft tissue deformation Vertical orientation of the leg during testing to apply a traction force at the knee to eliminate bone cartilage contact forces contributing resistance to tibial shear displacement Vertical orientation of the leg to prevent the wight of the leg and testing device from applying a tibial shear force

Technology Application

Quantify the F-D behavior of an ACL in-vivo Pre-injury diagnostic tool

Detailed Technology Description

The Anterior Cruciate Ligament (ACL) is a major knee ligament that is commonly injured in athletes and these injuries are a significant clinical issue. The ability to quantify ACL behavior quickly in vivo provides a means to explore a variety of theories regarding knee injury mechanisms and interventions to prevent ACL injury. Researchers at UC Davis have developed a device that allows relatively rapid (within minutes) quantification of the anterior/posterior shear force displacement (F-D) of the human knee, which is an indicator of the F-D behavior of the ACL. This device has potential as a diagnostic tool to detect ACL changes that may be predictive for subsequent catastrophic injury and therefore could be useful for physicians.
