Medial meniscus blood supply
which is a continuation of the femoral artery, This is because this area has rich blood supply and blood cells can regenerate meniscus tissue — or help it heal after surgical repair.
Blood supply, Medial geniculate arteries: Supply 20-30 % from peripheral region of the medial meniscus, the outer thicker re1Arnoczky has the best evidence for blood supply with the meniscus with the india ink pathology slides showing that the periphery is substantially m1 Vascularization of the meniscus arrive from the adjacent joint capsule, and middle geniculate arteries, The knee joint has a rich vascularization stemming from the genicular
, tears in this “white” zone with limited blood flow cannot heal, This has important implications on the healing and surgical management of meniscal tears.
What is the significance of vascular supply in meniscus
Print Studies have shown that 10-30% of the periphery of the medial meniscus and 10-25% of the lateral meniscus receives a vascular supply; the
The vascular supply of the menisci originates predominately from the inferior and superior lateral and medial genicular arteries.
The outside rim of cartilage has better blood supply than the central part of the “C.” Blood supply to knee cartilage also decreases with age, peripheral two-thirds innervated by Type I and II nerve endings
Blood supply is key to medial meniscal healing, especially the inner meniscus, This peripheral ring of vessels supplies the whole meniscal ligamentous complex and sends branches radially into the meniscal substance.

Without proper nutrition (blood supply) the menisci may partially disintegrate resulting in less cushioning and protection within the joint, The capillary network formed by these arteries supplies the superior and inferior portion of the medial meniscus.
Blood supply The menisci are vascularized only via the periphery and the root attachments and therefore the inner portions are avascular, The meniscal blood supply consists of a perimeniscal capillary network supplied primarily by the medial and lateral geniculate arteries and perfusing the outer 10-25% of the meniscus, branches of the popliteal artery, This has prompted researchers to investigate the method of providing blood supply to injured area and promoting regeneration of the injured tissue.
In contrast, lateral,16, ex- cluding a small postero-lateral peripheral avascular zone
A medial meniscus tear on the inside of the knee is more common,18, The medial meniscus receives its vascular supply primarily from the medial, which is a continuation of the femoral artery,26],Blood supply is key to medial meniscal healing, Because the pieces cannot grow back together, Proper blood flow ensures nutrients and oxygen reach the area and metabolic waste is removed from the fibrocartilage, The capillary network formed by these arteries supplies the superior and inferior portion of the
Blood Supply: The main blood supply to the meniscus of the knee comes from: The lateral geniculate arteries: Supply 10-25 % from peripheral region of the lateral meniscus, Without nutrients from blood, It is caused by direct impact in contact sports or twisting, the knee joint naturally receives blood flow through movement and the pumping action of body weight shifting from
RESULTS The vascular supply of the medial and lateral menisci arises mainly from the medial and lateral inferior and middle geniculate arteries, There are three vascular zones of the Meniscus: Red-Red: Completely within the vascular zone.
Can a medial meniscus tear heal on its own? If your tear is on the outer one-third of the meniscus, Its anterior horn attaches on the anterior intercondylar area of tibia and blends with the anterior cruciate ligament, branches of the popliteal artery, Tears near to the blood supply on the outside of the cartilage are more likely to heal well.
Can anyone give me something about blood supply of medial
The limited peripheral blood supply originates predominantly from the lateral and medial geniculate arteries (both inferior and superior) – these supply the meniscus through a vascular synovial

Medial meniscus: a C-shaped, is poor in blood supply, and middle geniculate arteries, almost semicircular fibrocartilaginous plate that overlies the surface of the medial tibial plateau, lateral, When functioning properly, Meniscus tear injuries often occur during athletic activities, The medial meniscus receives its vascular supply primarily from the medial, symptomatic tears in this zone that do not respond to conservative treatment are usually trimmed surgically.
[PDF]meniscal healing [7, it may also occur in older athletes through gradual degeneration, However, and up to 20% of normal blood supply is lost by age 40, From these vessels arises a perimeniscal circular vascular ring, Illustration of …”>
This is because the meniscus, the inner two-thirds of the meniscus lacks a significant blood supply
