MRI parameters measured for evaluation of tibial plateau morphology. Coronal proton density-weighted MR images showing: a TW, maximum tibial plateau width (double-headed arrow). b On the slice showing the peak of the medial tibial eminence (yellow point), HMTS was the distance from the tip of the medial tibial spine to the imaginary tibial joint line (double-headed arrow), and LSAMTE was the angle between the line drawn along the lateral slope of the medial tibial spine and the imaginary tibial joint line. c On the slice showing the peak of the lateral tibial eminence (blue point), HLTS was the distance from the tip of the lateral tibial spine to the imaginary tibial joint line (double-headed arrow), and LSALTE was the angle between the line drawn along the lateral slope of the lateral tibial spine and the imaginary tibial joint line. d TEW was the distance between the peak of the lateral and the medial tibial eminence (double-headed arrow). Note that the positions of the yellow point and the blue point are different on the coronal images
