Fig. 2From: Influence of the image levels of distal femur on the measurement of tibial tubercle-trochlear groove distance—a comparative studyMarkings of the anatomical landmarks for the measurement of the tibial tubercle-trochlear groove distance. The deepest point of the trochlear groove, the points of tangency of the posterior femoral condyles, and the most prominent point of the tibial tubercle are identified and marked. a CT of the distal femur. b MRI of the distal femur with cartilaginous landmarks. c MRI of the distal femur with osseous landmarks. d CT of the proximal tibia. e MRI of the proximal tibiaBack to article page
