Wear in uncemented porous and cemented polyethylene sockets: a randomised, radiostereometric study

Önsten, Ingemar LU ; Carlsson, Åke LU and Besjakov, Jack LU (1998) In Journal of Bone and Joint Surgery: British Volume 80-B(2). p.345-350
Abstract
We used radiostereometric analysis to compare wear rates between uncemented porous sockets and cemented all-polyethylene sockets in a series of 102 hips randomised for either a Harris-Galante or a Charnley cup. Wear was evaluated in 95 hips at a mean of five years (2 to 7). All hips had a cemented, 22 mm head mono-bloc Charnley stem. The mean annual wear rate was 0.09 mm in the Charnley sockets and 0.10 mm in the Harris-Galante sockets, with no statistically significant differences in wear, migration or rotation. We conclude that, up to five years, the wear characteristics of the modular and porous Harris-Galante socket resemble that of the Charnley socket.
