Complex Total Knee Arthroplasty (Knee Replacement)



– A 76-year-old woman had a broken leg followed by an infection when she was 12. She had lived with her deformity for years but now suffers from increasing sharp pain in her knee. She has only 40 degrees of motion in her knee, which is far below normal.


– X-rays show marked deformity of her tibia (shinbone) and femur (thighbone), with severe arthritis and subluxation (partial dislocation) of her knee joint.



– X-rays after her 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.
