To study the in vivo damage of the polyethylene acetabular cup retrieved at revision surgery was investigated, Mechanical properties were measured by a viscoelastic spectrometer and a universal Instron type testing machine with a torque meter. The following results were obtained ; 1) There was a positive quadratic correlation between stiffness of the acetabular cup and the duration from the implantation until the revision surgery in the case of the Weber type artificial hip joint. 2) There was a negative qudratic correlation between tan δ and the duration from the implantation until the revision surgery in the case of the Weber type artificial hip joint. 3) There was positive correlation between stiffness of the acetabular cup and the duration from the implantation until the revision surgery in the case of the Kyocera type artificial hip joint. 4) There was a negative correlation between tan δ and the duration from the implantation until the revision surgery in the case of the Kyocera type artificial hip joint. 5) There was a positive correlation between linear wear and the duration from the implantation until the revision surgery in the case of both the Weber and the Kyocera type artificial hip joints. 6) There was a positive correlation between torque and the duration from the implantation until the revision surgery in the case of both the Weber and Kyocera type artificial hip joints.
