Evaluation of the Fixation of Artificial Hip Joint by Acoustic Emission

The fixation between an artificial joint and the bone becomes loose with time. To avoid this loosening, and there by increase the life of the artificial joint, it is important to detect the loosening at a very early stage. In this paper, we tried to detect the loosening of an artificial hip joint by recognizing analyzing acoustic emission from it. More than 200 measurements were taken and it is clear that the AE method is very efficient and sensitive for evaluation of the fixation condition of an artificial joint.
