title: Revision total hip arthroplasty using a cementless modular femoral hip design.
abstract: The difficulty in selecting the "ideal" components for revision total hip arthroplasty is one factor leading to poor outcomes. For femoral hip components, loosening rates of femoral revision have been reported with different types of designs. Because of improved rates with more porous components, the use of cementless femoral revision is highly attractive. This article describes a cementless femoral revision component, the ZMR system, which addresses the challenges and design goals of revision as well as surgical philosophy: off-the-shelf flexibility, proximal-distal extensive fixation, restoration of kinematics (offset, let lengths, anteversion, and muscle tensioning), and implant integrity.
