Soft tissue releases, bone preservation and patient outcome following revision of the oldest total knee replacement.

The patient had a total knee replacement for arthritis secondary to Stills disease performed 35 years earlier, with 20 years of good function followed by 15 years of progressively worsening knee pain. A revision was completed, which improved the patient's quality of life and objective knee scores, with an increase in Oxford Knee Score from 22 to 42 and American Knee Society Score from 76 to 170. We discuss the technical aspects in revising this knee replacement, which is the oldest that we are aware of. The result has been a good recovery, which is the first available in the literature for future comparison. 2015 BMJ Publishing Group Ltd.
