Outline of Final Research Achievements	Anterior cruciate ligament (ACL) is a primary restraint of anterior knee laxity and often injured by sports activities. The Lachman test is the most sensitive test which detect "the end point". The goal of this study is quantification of the end point using force sensor. Finger force sensor were attached to the fingers and stress onto the fingers were measured by 8 finger force sensors. End point is detected by the absolute values of the force and time on changing force. Optimal setting positions for the finger force sensors were also detected. In addition, feasible and portable systems were developed for the daily clinical use for detencting ACL deficiency by tablet personal computer. Further studies wer required to verify this system to detect the ACL deficiency at a certain degrees of sensitivity and specificity.
