Fig. 1From: Computed tomography-based patient-specific cutting guides used for positioning of the femoral component of implants during unicompartmental knee arthroplasty: a cadaver studyPreparation of individualized cutting guides. (A) the line joining the center of the femur and the center of the femoral head was defined as the femoral mechanical axis. (B) in the coronal plane, the alignment of prosthesis at the midline of medial condyle of the femur (line a) should be parallel to the femoral mechanical axis (line b). (C) in the sagittal plane, the alignment of femoral prosthesis (line a) should be posteriorly sloped to 10o relative to the anatomical axis (line c). (D) the optimal prosthesis was selected by simulated installationBack to article page
