After the 5-year re-approval of F1672, there was a request from Christian Kaddick to include flexion angles and corresponding loads when performing contact area and contact stress measurements. Therefore, this information and corresponding references is included in the proposed revision along with a Figure for a possible test set-up; and, an update regarding porous metal coating tensile and shear strengths. This revision proposal was discussed at the Anaheim meeting of F04.22.08 Patella Spec. task group and the subcommittee agreed to ballot the revision at subcommittee level.
