Additional manufacturer narrative- a2, a3, b5, h3.Updated investigation results-the cause of the patient¿s subsequent revision cannot be conclusively determined; however, it is most likely related to the patient¿s underlying condition of joint laxity as associated with the interaction between the implanted device and the patient that impacts the performance of the device.The patient was revised to a constrained device which will assist with joint laxity issues.These devices are used for treatment not diagnosis.There is no additional information available.
