Revision Total Knee Arthroplasty (Knee Replacement)



– A 63-year-old man had a total knee replacement in 1992. The original knee replacement was itself replaced, or “revised”, in 2001. He reports increasing pain in his knee and requires narcotic pain medication for relief. A repeat revision was recommended.


– X-rays show loosening of the replacement with a shift of the component position inside the bone.



– X-rays after his knee replacement show restored alignment between the bones of the knee.


– Even with extreme and long-standing arthritis, replacement can often improve or restore function. This patient experienced complete pain relief, increased motion to 90 degrees, and has been able to be involved in exercise classes.
