Developing a new robot based testing methodology to deepen clinical investigations surrounding the knee joint

Industrial robots have become widely used for studying human joint kinematics, particularly in the context ofknee motion research. Previous research focused mainly on quasi-static loading, but recent trials have shifted the focus to dynamic tests mimicking in-vivo motion, enhancing the investigation of joint biomechanics. This study aims to develop a physiologically relevant robotic test to simulate human walking on cadaveric knees accounting for the inherent variation in knee geometries through specimen specific gait adaption. Although similar tests have been conducted, this study evaluates the tests impact and utility through comparison with conventional laxity tests.
