A HKA; B Measurement of medial meniscus extrusion. Two vertical lines were drawn perpendicular to the articular horizontal line at the outer edges of meniscus and the outer edge of the articular cartilage of the tibial plateau. Absolute extrusion was defined as the distance (a) between the outer edge of the articular cartilage and the outer edge of the medial meniscus; C The included angle formed by the connection between the vertical line of the longitudinal axis of the tibia and the highest point of the anterior and posterior edge of the widest sagittal plane of the medial tibial plateau is the MPTS
