title: Long-term evaluation of hip arthroplasty in patients with an ipsilateral knee arthrodesis.
abstract: Hip arthroplasty with an ipsilateral knee arthrodesis occurs infrequently but does raise concern regarding surgical technical difficulties, dislocation, sepsis, and long-term loosening. Sixteen patients were evaluated 7.5 years (average period) after surgery. Technical difficulties were not prohibitive. No dislocation or revision was necessary in any of the cases. Two patients died as a result of unrelated sepsis from an infected knee. Loosening and protrusio of the acetabulum occurred in two patients. Hip arthroplasty in patients with a fused knee does not incur undue risk of loosening or instability and can provide long-term good function and pain relief. Patients with multiple joint arthroplasties, in whom concurrent sepsis occurs, can have devastating results.
