Abstract
An arthroscopic indenter for measuring creep deformation behavior, stress relaxation behavior and thickness of cartilage in vivo and in situ. A computer-based system measures deformation or force information upon cartilage and processes that information for closed-loop control of an indenter tip while also calculating intrinsic properties associated with the cartilage such as stiffness, compressibility and/or permeability.
