title: Computer-assisted surgery in revision total knee arthroplasty: early experience with 46 patients.
abstract: Use of the OrthoPilot navigation system (B. Braun Aesculap, Tuttlingen, Germany) in navigated revision surgery allows for precise alignment of components, restoration of the joint line, balance of the gaps, and filling of the bony defects by facilitating selection of appropriate implant sizes and wedges. Our study results confirm these benefits through clinical and radiologic evaluation of the first 46 cases in our series in which the system was used. Continuous feedback from the system during surgery confirms that the surgeon is using proper technique. The OrthoPilot navigation system simplifies revision surgery and helps produce successful patient outcomes.
