Biomechanical considerations in revision arthroplasty.
Accumulated knowledge about hip replacement arthroplasty has identified a number of mechanical factors that contribute to implant failure. The mechanics of component design, materials selection, implant fixation, and response of bone and soft tissue structures to an altered loading environment are variables that influence outcome. Revision arthroplasty presents additional problems of loss of bone stock, cortical perforation or fracture, and implant removal that must be appreciated to prevent recurrent failure.
