Fig. 2From: Knee-ankle joint line angle: a significant contributor to high-degree knee joint line obliquity in medial opening wedge high tibial osteotomya mLDFA: the lateral angle formed between the femoral mechanical axis (indicated by the orange line) and the joint line of the distal femur (indicated by the green line), b KJLO: the angle between a line tangent to the articular surface of the proximal tibia (indicated by the orange line) and a line parallel to the ground (indicated by the green line), c AJLO: the angle between a line tangent to the articular surface of the distal tibia (indicated by the orange line) and a line parallel to the ground (indicated by the green line). d JLCA: the angle between a line tangent to the articular surface of the distal femur (indicated by the orange line) and a line tangent to the articular surface of the proximal tibia (indicated by the blue line)Back to article page
