Abstract
We present a precise method of measuring the displacement of soft tissue us ing a probe with a compliant needle. The displacement vector is set using t wo needles which are fixed in the tissue. The new method was applied to mea sure the displacement of a porcine meniscus in the transverse plane under j oint load. The meniscus moved 0.5 - 1 mm outward under joint load of 600 N in 2 seconds. Then, slow displacement due to creep deformation followed. Th e results show approximate agreement with previous predictions by computer simulation and strain measurement.
