Fig. 2From: Are three-dimensional patient-specific cutting guides for open wedge high tibial osteotomy accurate? An in vitro studyAngle measurements on 3D models. a mMPTA measures the medial angle between the tibial mechanical axis and the tangent mediolateral line of the tibial plateau in the frontal plane. b PTS is the posterior angle between the orthogonal line to the mechanical axis and the anteroposterior tangent line of the medial plateau in the sagittal planeBack to article page
