Abstract

In vitro testing of the human knee provides valuable insight that contributes to further understanding knee biomechanics. Cadaveric testing correlates well with clinical trials because the tissue has similar properties to that of live subjects. In addition, in vitro testing allows studies to be performed that would otherwise be unethical to evaluate in vivo. Due to their many advantages, cadaveric testing has been utilized to evaluate many of medical devices and surgical techniques that have been developed in recent decades. This article aims to review the current technologies and methodologies utilized in experimental in vitro testing of the human knee. The article provides a summary of the different rigs and machines that are currently used to examine the biomechanics of the knee. It also highlights the variable experimental techniques and measurement systems that are used to collect the kinematics and kinetics of the knee joint. As technologies advance so do the measurement systems and equipment in the experimental biomechanics field. The influence of improvements to these testing equipment and measurement devices on in vitro testing of the knee will also be discussed in this review.
