FAQ: What Is A Meniscus Anatomy?

What is the meniscus and what is its function?

The meniscus is often thought of as being shock absorbers between the thighbone and the shinbone. They work to help in the reduction of wear and tear on the knee’s cartilage and bones and assist in guiding movement.

What is a meniscus made of?

The meniscus cartilage itself is made up of a softer fibrocartilage. The knee has two C-shaped meniscus structures made of a softer fibrocartilage. These structures are anchored to the tibia by the peripheral capsular attachments of the menisci, which allow them more mobility within the joint.”

What is the role of the meniscus?

The menisci of the knee joint are crescent-shaped wedges of fibrocartilage that provide increased stability to the femorotibial articulation, distribute axial load, absorb shock, and provide lubrication to the knee joint. Injuries to the menisci are recognized as a cause of significant musculoskeletal morbidity.

What is a menisci?

The meniscus is a c-shaped pad of cartilage in the knee that acts as a shock absorber. Each knee has two menisci.

Will walking on a torn meniscus make it worse?

People usually feel pain, but can still walk. Sometimes swelling also occurs and it may get worse over time. You also might feel your knee getting stiffer.

What is the difference between lateral meniscus and medial meniscus?

The menisci — the medial meniscus and lateral meniscus – are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). They act as shock absorbers and stabilize the knee. The medial meniscus is on the inner side of the knee joint. The lateral meniscus is on the outside of the knee.

Which meniscus is more mobile?

The lateral meniscus is more mobile than the medial meniscus as there is no attachment to the lateral collateral ligament or joint capsule. The outer edges of each meniscus attach to the tibia by the short coronary ligaments. Other short ligaments attach the ends of the menisci to the tibial surface.

What part of the meniscus of the knee is poorly vascularized?

Various zones of the meniscus are described based on the blood supply; the red zone is the well- vascularized periphery, the red-white zone is the middle portion with vascularity peripherally but not centrally, and the white zone is the central avascular portion.

Where is meniscus pain felt?

Common symptoms of a meniscal tear may include: Localized pain near the area of the tear. In tears of the lateral meniscus, this discomfort will be present along the outside edge of the knee. Pain will manifest on the inside edge of the injured knee for tears of the medial meniscus.
