Abstract:
We performed 33 cementless total hip arthroplasties for arthritis in 27 patients with an established diagnosis of Paget's disease on the acetabular or femoral side of the hip. There were 3 revisions. One stem for aseptic loosening at 55 months, and 2 stems after periprosthetic fractures at 9 and 70 months. Twenty-three cases were available for follow-up at an average of 6.7 years (range, 2-14 years). Harris hip score improved from 56/100 preoperatively (16-98/100) to 90/100 postoperatively (78-100/100). All surviving components were radiographically bone ingrown. Based on our findings, it appears that a cementless total hip arthroplasty can have a good outcome in Paget's disease.
