Isolated unicompartmental osteoarthritis in the young patient is a difficult problem to treat; they may be too young to consider total knee arthroplasty due to difficulties with inevitable future revision. Unicompartmental knee arthroplasty is one possible solution as it is perceived by some as being a smaller surgical insult than total knee arthroplasty, with easier revision to total knee arth...

BACKGROUND Unicompartmental knee arthroplasty is a less-invasive alternative to total knee arthroplasty for patients with arthritis affecting only the medial or lateral compartment. However, little is known about recent trends in the use of these procedures and the associated outcomes among older patients. METHODS With use of a nationally representative 5% sample of Medicare beneficiaries who...

The principles of revision arthroplasty are to understand the cause of failure, adequate surgical exposure, restoration of limb alignment, achieving appropriate soft tissu...
