Introduction

Cementless acetabular components may have to be revised for different reasons.

Methods

We analysed the reason for revision of 54 CLS cups out of a series of 3371 CLS cups, which had been implanted between 1988 and 2002.

Results

The reason for revision was aseptic loosening in 14 cases, recurrent dislocation in 11 cases, infection in 6 cases, a fracture of the implant in 3 cases, an irritation of the tendon of the iliopsoas muscle in another 3 cases. Two cups were revised together with the stem after a periprosthetic fracture. 15 CLS cups had been combined with a cemented titanium-alloy stem with a known high rate of aseptic loosening and were revised together with the stem. 23 cups were considered stable at surgery but due to the design of the cup nonetheless easy to remove without bone loss. In all cases the new implants could be fixed without difficulties.

Conclusions

We conclude that the CLS cup is very easy to revise, without bone loss or compromise of the stability of the new implant.
