After doing UW questions asking about Knee MRI's, how do you tell if you're looking at the femur or tibia? I understand that the ACL is from the ant part of the tibia to the post part of the femur...and the PCL is from the post part of the tibia to ant part of femur. but still, i can never tell if the x-section is of the femur or tibia...
