I live in Ct. and am looking for a Dr. with the expertise of Dr. Henry Finn ,but in Massachusetts. My second 2 stage revision is a hinge . I see on my last MRI it is loosening. Just over a year with this one. Devastated. Appointment next week on my 72nd birthday. Had asked before what would happen if this failed. Fusion was the answer, then amputation if that failed too. I'm curious about the knee replacement after a fused knee. My components are very long in my leg Any help or suggestions? Anyone have issues with loosening cement?
