Arthritis in canines often leads to joint degeneration and rupture of the Anterior Cruciate Ligament (ACL). Diagnosis of this condition is often difficult because the current methods used are non-quantitative. The aim of this project is to quantify the amount of tibial translation in a canine’s leg caused by a known applied force in order to determine the severity of an ACL rupture. Preliminary parts for a device that can accomplish this have been developed and it is the goal of this team to create and test a working model.

Force measurement and displacement measurement devices have been fabricated. Calibration testing shows both devices have repeatable output values. Cadaver testing shows that the displacement device is sensitive enough to detect full ACL rupture.
