I'm sorry to hear of your struggles. My husband had three TKR Revisions over 8 years due to Aseptic loosening. Unfortunately, during recovery from the last surgery he developed a staff infection. Been in antibiotics now for 8 months and we're just waiting for the loosening his surgeon expects will occur this time because of infection. Only options are yet another revision or above the knee amputation. My husband was an avid hiker and very active. May get another opinion but he has a well-respected Revision specialist do not sure whether it will be useful.
