Abstract

An arthroscopic cartilage evaluator for determining the Index of Structural Integrity of articular cartilage. This computer-based system measures deformation or reaction force of articular cartilage and processes that information for closed loop control of a testing tip and allows the measurement of stress relaxation behavior or creep behavior in vivo and in situ. This evaluator also allows the calculation of the tissue's material properties.
