When a replaced hip wears out in course of time, a revision hip replacement becomes unavoidable. Unfortunately the revision Hip Replacement is not an easy matter and there can be many complications in the revision hip replacement surgeries. So surgeons delay hip replacement surgeries to the maximum possible extent so that the necessity for revision hip replacement may not surface. But if ceramic prosthesis is used in the initial hip replacement surgery it is found that they last longer and revision hip replacement surgery is not necessitated as they last over the life time of the patient.
Hip replacement in younger people is found to erode faster than in older people because the wear and tear in their case will be more than that in the case of less active older people. It has been found that the wear and tear of plastic prostheses is at the rate of 0.1 mm per year.
