This invention is an articular cartilage evaluator (110) 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 (122) and allows the measurement of peak force, stress relaxation behavior or creep behavior in vivo and in situ. The evaluator (110) also allows the calibration of the tissue's material properties. A calibrator (300) is also provided for calibrating the evaluator and removing a replaceable tip assembly (123).

Dispositif d'évaluation (110) de cartilages articulaires destiné à déterminer l'indice d'intégrité structurale de cartilages articulaires. Ce système informatique mesure la déformation ou la force de réaction de cartilages articulaires grâce au fonctionnement en boucle fermée d'une pointe (122) de test et permet la mesure de la force maximale, du comportement de relaxation ou du comportement de fluage in vivo et in situ. Ledit dispositif d'évaluation (110) permet également l'étalonnage des propriétés des matériaux des tissus. En outre, un dispositif d'étalonnage (300) est destiné à étalonner le dispositif d'évaluation et à enlever un ensemble pointe remplaçable (123).
