Mimics software v14

A CT scanner (LightSpeed VCT, GE Medical Systems, Milwaukee, WI, USA) was used for all examinations. It was taken within 1 week after operation for all patients. The collimation was 16 × 0.625 mm. The tube parameters were 120 kVp and 200 mA. The acquisition matrix was 512 × 512. The field of view was 140 mm and the slice thickness was 0.625 mm. The knee was placed in full extension. The bone was segmented and reconstructed to 3D point cloud model from the axial CT scan slices with use of Mimics software v14.0 (Materialise, Leuven, Belgium). The reconstructed 3D point cloud bone models were then imported in the commercial package Geomagic Studio v10.0 (Research Triangle Park, NC, USA) for processing into 3D surface models.
