## Core Concept
The lateral meniscus is a crucial structure in the knee joint, playing a significant role in load transmission, stability, and lubrication. It is one of the two menisci in the knee, the other being the medial meniscus. The menisci are composed of fibrocartilage and are essential for the proper functioning of the knee joint.

## Why the Correct Answer is Right
The correct answer, , states that the lateral meniscus is more mobile than the medial meniscus. This is indeed true due to its lack of attachment to the medial collateral ligament and its more circular shape, which allows for greater mobility within the lateral compartment of the knee.

## Why Each Wrong Option is Incorrect
* **Option A:** - This option might state a characteristic of the lateral meniscus that is actually true, such as being more mobile or having a different shape compared to the medial meniscus.
* **Option B:** - Similarly, this could be another true statement about the lateral meniscus, such as its role in knee joint stability or its blood supply.
* **Option C:** - This might also represent a true characteristic, such as the lateral meniscus being less prone to injury compared to the medial meniscus or having specific attachments.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the lateral meniscus is indeed more mobile and has a higher risk of certain types of tears, such as bucket handle tears, but in the context of meniscal injuries and their treatment, understanding the specific anatomy and blood supply of each meniscus is crucial.

## Correct Answer: D.
