Despite evidence of long term survival of cemented femoral stem prostheses, studies have shown concerns in the longevity of the cemented sockets. This has led to a rise in the use of uncemented and hybrid implants (with uncemented cup and cemented stem) without long term studies to determine evidence for their use. We aimed to assess whether there is any difference in clinical outcome between cemented and non-cemented acetabular fixation in elderly patients. Between February 2001 and August 2006 186 patients over 72 years of age were prospectively randomised to receive either a cemented Exeter cup or a HA coated press fit cementless cup. Both groups received a cemented Exeter stem. The patients were assessed pre-operatively and reviewed at 6 weeks, 6 months and yearly in a research clinic, by an independent observer. Outcome measures were the Merle D'Aubigné, Postel, Oxford Hip and Visual analogue pain scores. The implants were also assessed radiographically and all complications were recorded.Introduction
