No. I have not had the revision and am mostly in a wheelchair now. I found out through a rating company that my surgeon, Dr Penenberg, out of Cedars Sinai who was supposed to be "the doctor's doctor is rated very poorly for knees. He is a 100 out of 800 and that is the worst rating. He is a 740 for hips but knees not so good. I did find a doctor in Henderson, Nevada, a Dr Tait, who uses the Aesculap system but I can't see him until September. He is rated a 600 so that is the bottom of the excellent ratings which go from 600 to 800. I don't know what to do and am frightened. My knee is extremely painful. I cannot go from a bent postion to a straight position without excruciating pain and I can't go from a sitting position to a standing position once again without excruciating pain. Dr McPherson in LA is rated a 540 which isn't that good either. He is the only one who I can find in the Los Angeles area who uses the Aesculap. The hospital that he works out of is St Vincents and that is rated a D for infections so forget that. I have heard of Dr Hernandez but he is only rated a 570 so the ratings scare me and the hospital that he works out of isn't rated very well either. I do not know if he uses the Aesculap knee. I have developed two more allergies to two metals since I had the Smith and Nephew Oxinium knee put in so the Oxinium knee isn't necessarily the answer for people with metal allergies I guess. Titanium knees do have nickel in them so they are out. The only one is the Aesculap knee and that is totally covered in Zirconium. I am not reactive to Zirconium on the metal test but I am close to a low reaction. That is scary to me because the two metals that I am now sensitive to were negative but close to the low reactive line before I had the replacement surgery. I guess I develop sensitivity once the thing is inplanted. I am terrified that I will lose my leg one day so I sit in my wheelchair. This is no way to live.
