Unpredictable progression of osteolysis following cementless hip arthroplasty 24 femoral components followed for 6–10 years

Abstract

We reviewed 24 hips that developed femoral osteolytic lesions following cementless total hip replacement with a Porous-Coated Anatomic prosthesis after a mean of 8 (6–10) years. 15 of the hips showed hardly any radiographic deterioration in the osteolysis. 2 became much worse with dramatic loss of bone stock. Both of these hips required revision of the acetabular component as well as bone grafting of the otherwise well-fixed femoral component. The remaining 7 hips showed mild-to-moder ate enlargement of the lesions. All 24 hips were asymptomatic.
