Abstract
An articular cartilage evaluator for determining the Index of Structural Integrity of articular cartilage. This computer-based system measures deformation or reaction force of articular cartilage through closed loop control of a testing tip and allows the measurement of peak force, stress relaxation behavior or creep behavior in vivo and in situ. This evaluator also allows the calculation of the tissue's material properties. A calibrator is also provided for calibrating the evaluator and attaching and removing a replaceable tip assembly.
