According to the team's findings, published in Orthopaedic Journal of Sports Medicine in 2020, extrusion of the meniscus occurs first. These meniscus changes can then concentrate forces on the meniscal root attachment to the bone, causing breakdown as the attachment begins to tear away.

Formed by three bones, the knee joint is typically a tough, strong joint. But it is not necessarily the most flexible when it comes to rotating in certain directions. During some activities — especially contact sports — the force and degree of twisting your knee can tear some of the wedge-shaped cartilage that provides cushioning between your thigh...
Endurance is an important part of sports. For some athletes, playing through a little pain is a badge of honor. In the case of meniscus tears, some people think the injury will heal over time on its own. But the truth is that there are different types of meniscus tears — and some tears won’t heal without treatment. If your tear is on the outer one-...
The first step in treating a torn meniscus is getting the injury examined by a physician who specializes in orthopedics. During the exam, they may check the tenderness of your knee joint and move your leg to get a measure of your knee’s range of motion. They may also order imaging test, such as an MRI or X-ray, to determine the exact location and s...
When the meniscectomy or meniscus repair is complete, the surgeon closes the portals with stitches or surgical strips. Then the team will cover your knee with a bandage. What happens after meniscus repair or meniscectomy? Most people who have meniscus repair or meniscectomy don’t need to stay overnight at the hospital.
Nov 3, 2021 · Meniscal extrusion, referred to as an external displacement of the meniscus, is a commonly encountered but often overlooked magnetic resonance imaging finding in the knee joint. Meniscal extrusion alters the biomechanical properties of the meniscus, leading to accelerated cartilage degeneration and early osteoarthritic changes.

May 13, 2023 · An extruded meniscus could be a manifestation of other pa-thologies such as disruption of coronary ligaments, cartilage loss, knee malalignment, ligament injuries, or OA. ME is strongly associated with osteoarthritis features, particularly with bone marrow lesion and cartilage damage.
Jul 18, 2022 · The mechanical damage of the meniscus caused by extrusion seems to change the loading-bearing capacity of the tibiofemoral compartments, leading to the destruction of the articular cartilage as well the subchondral bone, ultimately contributing to the development or progression of OA [87, 89, 92].
