Fig. 1From: Comparison of in vivo knee kinematics before and after bicruciate-stabilized total knee arthroplasty during squattingComputed tomography slices were used to create density-based digitally reconstructed radiographs (DDR) of the femur (a) and the tibia (b), which were projected onto the radiographic images of the preoperative knee. Computer-aided design data of the femoral (c) and tibial (d) components were also projected onto radiographic images of postoperative kneeBack to article page
