Knee laxity evaluator and motion module/digitizer arrangement

Abstract

Abstract The invention relates to a knee laxity evaluator which consists of an instrumented seat (9), a restraint means (7) for restraining the thigh of a patient to the instrumented seat, a motion module (11) for measuring motion of the unres­ trained part of the leg relative to the thigh of the patient, and processor means for analyzing outputs of the instrumented seat and the motion module to provide indications of applied force and relative motion. The invention also relates to a specific motion module/digitizer combination which can be used as a part of the knee laxity evaluator, or which can be used independently or in alternate systems. The invention also relates to a novel dynanometer for use in the knee laxity evaluator which includes a triple beam arrangement.
