Navigation-Assisted Total Knee Arthroplasty for Osteoarthritis with Extra-Articular Femoral Deformity and/or Retained Hardware

Figure 2

Estimated distal femoral cut line (solid line) perpendicular to the mechanical axis (dashed line) does not compromise the collateral attachment in anteroposterior radiograph (a). Anterior femoral surface (solid line) is 13° flextion to the mechanical axis (dashed line) in lateral view (b). Intraoperative estimation of the distal femoral cut line and thickness of the resected bones were calculated by the navigation system (c).
