The nine- to fifteen-year follow-up of one-stage bilateral total hip arthroplasty.

Careful selection and preoperative evaluation of patients with bilateral hip disease for one-stage bilateral total hip arthroplasty can yield satisfactory results consistent with those published for unilateral hip disease. These patients are generally younger and more active than patients undergoing unilateral total hip arthroplasty and require meticulous attention to both technique and prosthetic design. The authors found that the Charnley design remains the gold standard against which other prostheses must be measured in the long-term follow-up.
