Confirmation of the varus/valgus, posterior slope, and rotation angles after bone resection using the AR-KNEE system. The surgeon checked the angles of tibial resection by placing the oval guide (resin marker with oval two-dimensional bar code) on the resected bone surface. In this case, the AR-KNEE system showed a varus angle of 0.2°, posterior slope of 4.1°, and external rotation of 0°
