We report the long-term results of revision total
hip replacement using femoral impaction allografting with both uncemented
and cemented Freeman femoral components. A standard design of component
was used in both groups, with additional proximal hydroxyapatite
coating in the uncemented group. A total of 33 hips in 30 patients received
an uncemented component and 31 hips in 30 patients a cemented component.
The mean follow-up was 9.8 years (2 to 17) in the uncemented group
and 6.2 years (1 to 11) in the cemented group. Revision procedures
(for all causes) were required in four patients (four hips) in the
uncemented group and in five patients (five hips) in the cemented
group. Harris hip scores improved significantly in both groups and
were maintained independently of the extent of any migration of
the femoral component within the graft or graft–cement mantle.
