Why do hip replacements wear out?The forces acting on the hip joint are several multiples of your body weight. Most adults take 3-4 million steps per year and this all contributes to wear over time.
The friction and wear is primarily at the articulation, were the head moves in the cup. Additionally repeated loading of the joint is transmitted through the implant to the supporting bone. What is the effect of wear in a hip replacement?Wear may become apparent by causing local tissue reaction, loosening of the fixation to bone, or mechanical failure of the implant.During review of hip replacements it is important to consider a wide range of possible "modes of failure", and then act accordingly.
