Clinical experience with primary cementless total hip arthroplasty.
One hundred-eleven patients (121 hips) treated with cementless total hip arthroplasty (Harris-Galante, Zimmer) were clinically and radiographically reviewed at an average follow-up of 67 months (55-79). 9,1% of the stems presented signs of loosening and 5 stems (4,1%) had to be revised. None of the acetabula required revision surgery for loosening. One socket was revised due to recurrent dislocation. Clinical results were evaluated according to Harris protocol: excellent 75,2%, good 12,4%, fair 5%, poor 3,3%. Ten (7,9%) intraoperative fractures of the proximal femur were observed: in 2 cases stem instability consequently occurred. Endosteal cortical erosions, not clinically evident, were observed in 8,3% of stable stems. A foreign body biological reaction to polyethylene or metallic debris is supposed as cause of erosions.
