Is there a picture somewhere that shows the displacement of a meniscal root? I am trying to found out as much information.

AAOS.org. The american academy of orthopedic surgoens webite is a wonderful resource for patients and doctors. It has well researched information.
Meniscus problem. Some very nice MRI images of displacement of the meniscal root may be found at: http://www.Radiologyassistant.Nl/en/4b98adddb76db#p4b994129d4d7b.
