Gross morphology: (A) Healthy meniscus with a smooth and glistening surface. The anterior horns are smaller and the posterior horns show a broad base. (B) A larger fiber bundle/connective tissue bundle penetrates through the vascular zone into the meniscus tissue (←). (C) Degenerated menisci with severe tissue disruption (medial), fraying, small tears and calcium deposition. (D) Tissue tag or scar tissue most likely due to a flap tear (*).
