Abstract
An instrument and technique for measuring the compressive properties of a body (e.g., articular cartilage) are disclosed. The instrument includes an elongated probe, a biasing assembly for applying a pre-determined pre-load to the body to establish a measurement reference at the predetermined pre-load, an actuator to move the elongated probe to apply a compressive force to the body, and a measurement device which measures displacement of the elongated probe relative to the measurement reference.
