One-stage procedure for total knee arthroplasty in post-traumatic osteoarthritis of the knee with wound defect. Usefulness of navigation and flap surgery

The Knee, 04/26/2012

The results of total knee replacement in post–traumatic knee arthritis are not as satisfactory as in degenerative situations. In severe malalignment due to bone landmark changes following malunions, computer–assisted surgery gives immediate correct references for final positioning of implants and restoration of limb alignment. Implant selection must allow use of normal and revision components to fit the local anatomy. Commonly–used pedicle flaps such as the gastrocnemius flap are valuable to cover wound defects after prosthesis implantation. All these procedures can be used successfully in a one–stage surgical procedure.
