what does signal changes in the posterior left medial menicus and posterior lateral meniscus mean?

Degeneration: Mri scans image tissue by measuring hydrogen atoms such as are found in water (h2o - 2 parts hydrogen, 1 part water) . As a meniscus ages the tissue degenerates and is replaced by fluid which is mostly water. Increased MRI signal ( increased fluid) usually means some degeneration of the meniscus which is a consequence of aging.

Agree with the Dr Salvagno, description. For your question's answer; The posterior or back part of both the medial ( ie on the inner side) and lateral (ie, outer side) of the knee. Essentially if affects your knee both on the inner and outer aspects, towards the back part.

Not to worry : As we get older meniscus is more prone to degeneration after years of wear and tear. Signal change usually means this and doesn't mean tear
