A Ramp lesion in an ACL-injured knee on the sagittal plane of preoperative MRI. The signal intensity (white arrow) at PHMM was high, but it was uncertain whether there was a definite tear. B Anterior view using 30° arthroscopy. The medial meniscal tears were not confirmed during the anterior view examination using 30° arthroscopy and probing. C Transcondylar notch view using 30° arthroscopy. It was uncertain whether there was a definite tear in the peripheral area of the PHMM. D Posteromedial (PM) portal view using 70° arthroscopy. The tear was confirmed by probing through the transcondylar notch with a posteromedial portal view using 70° arthroscopy. E Transcondylar notch view using 70° arthroscopy. Ramp lesions could be easily identified
