It was reported a patient underwent an initial knee arthoplasty procedure on (b)(6) 2015.During the procedure, it was reported that position of the stem pin and tray hole did not match causing the tray and the stem to not fit well.There was a gap between the stem and the plate so the press fit was shallower than usual.The surgeon thought the pin might be pressed obliquely so he tried to disconnected the stem and the tray but could not.He felt that they were well fixed and he decided to neatly tighten post screw to complete the procedure.No adverse event occurred.
