Management of Bone Loss in Revision Total Knee Arthroplasty

by Thomas Parker Vail, MD

This presentation will deal with options for reconstructing bone defects in revision total knee arthroplasty and is a product of a symposium presented at the Knee Society meeting in March 2006. The treatment of bone defect is a burning issue in knee replacement surgery because there are unsolved problems in dealing with bone loss in revision knee arthroplasty; namely, unreliable fixation of the implant to bone; difficulty in achieving satisfactory alignment of the implant; and difficulty in achieving stability of the joint and balancing the gaps when there is bone missing. In order to deal with this list of problems, a number of techniques are required. This presentation will give an overview of the techniques and new technologies that are available to deal with these challenges in revision knee arthroplasty.

Developed in association with The Knee Society.
