The majority of component testing machines available today are multiple axial wear simulators that focus on the interaction between two articular surfaces [1, 2, 3]. The stability of the implant in the bone, another factor in joint replacement survival is usually tested using unvarying biaxial fatigue loading [4]. These loading protocols do not replicate physiological loading conditions. We designed the Dynamic Joint Force Simulator (DJFS) to have the capability to apply physiological loads through an articular surface for the purpose of studying implant stability.
