Finite element model. Finite element model from femur to tibia and fibula, which was based on a 65-year-old woman. The KL classification was grade 1, the FTA was 177.6°, the MPTA was 86.3°, the LDFA was 83°, and the JLCA was 1.1° in the full leg weight-bearing radiographs. MRI showed no posterior root tear of the medial meniscus, and the MME was 1.2 mm at the middle of the anteroposterior diameter of the tibia. KL; Kellgren-Lawrence, FTA: femolo-tibial angle, MPTA; medial proximal tibial angle, LDFA; lateral distal femur angle, JLCA; joint line convergence angle, MME; medial meniscus extrusion
