Total hip replacement with second generation cementing technique and the monobloc ScanHip: a 10-year follow-up

In 230 consecutive patients 244 hips were operated with a 32-mm cemented prosthesis. The mean age at surgery was 77 (46-96) years. At the 10-year follow-up 89 patients (95 hips) were dead and 33 patients (35 hips) did not attend because of old age or medical problems. Thirteen hips had been revised for aseptic loosening, two for infection, one for recurrent dislocations, and one for fracture. Four hips were found to be loose and seven had suspected radiographic loosening zones but only minor clinical symptoms. No or little limp was experienced by 52% of patients and 62% reported no or little pain. Eighty-seven percent were satisfied with the early postoperative result and 77% were still content at the time of follow-up. On the 10-year radiographs wear of the cups was, on average, 2.2 mm in loose hips and 1.5 mm in intact hips (P=0.02). There was no correlation between dissatisfaction and loosening visible by X-ray at follow-up.
