This ain't no joke Alan. I asked the doctor what life span of these titanium knees were & he said roughly 15 years. He also stated that he was in on the development of this series knee replacement. R I P doc. I haven't babied mine either with working on old Fords & Mercury's & climbing some pretty good mtn's hunting. Legs are giving out but the knee's keep on bending.
