Total knee arthroplasty with a long-stemmed component for fractures adjacent to the knee in rheumatoid arthritis: a report of four cases.

Four rheumatoid arthritis patients with fractures adjacent to the knee were treated by total knee arthroplasty with a long-stemmed component. All four fractures healed; joint reconstruction and limb realignment were achieved simultaneously. Total knee arthroplasty with a long-stemmed component was useful in stabilizing the fracture and rapidly restoring function in the joint and the limb.
