Event or Problem Description
It was reported that the patient's left knee was revised.As reported by rep: "the patient was getting out of a chair and the femur jumped the poly post anteriorly.The patient took a photo of this occurrence and showed it to the surgeon or he wouldn't have believed this was possible.Since then the patient has complained of a unstable knee associated with pain".Surgeon decided to implant a thicker poly with comment ".An industry potential criticism of this knee is that the post does not increase in size as the implant gets larger".
