The meniscus is a C-shaped piece of tough, rubbery cartilage that acts as a shock absorber between the shinbone and the thighbone. It can be torn if you suddenly twist your knee while bearing weight on it.
The medial meniscus is on the inside of the knee. The lateral meniscus sits on the outside of the knee. Both are shaped like Cs and provide cushioning between your shinbone (tibia) and...
The medial meniscus is a fibrocartilage semicircular band that spans the knee joint medially, located between the medial condyle of the femur and the medial condyle of the tibia. [1] It is also referred to as the internal semilunar fibrocartilage.
Types of meniscus tears. Each of your knee joints has two menisci: Medial meniscus: A medial meniscus tear affects the cartilage on the inside of your knee. Lateral meniscus: A lateral meniscus tear affects the cartilage on the outside of your knee.
But X-rays can help rule out other problems with the knee that cause similar symptoms. Magnetic resonance imaging (MRI). This uses a strong magnetic field to produce detailed images of both hard and soft tissues within your knee. It's the best imaging study to detect a torn meniscus.
The medial meniscus specifically forms almost a semicircular shape and covers 50-60% of the articular surface between the medial femoral condyle and the medial tibial plateau. It has a vascular supply and receives innervation from the posterior tibial, obturator, and femoral nerves. [3]
The medial meniscus sits on the inside of the knee and the lateral meniscus sits on the outside of the knee. Meniscus tears usually take place when an athlete twists or turns their upper leg while their foot is planted and their knee is bent.
The medial meniscus is on the inner side of the knee joint. The lateral meniscus is on the outside of the knee. Meniscus tears can vary widely in size and severity. A meniscus can be split in half, ripped around its circumference in the shape of a C or left hanging by a thread to the knee joint.
The medial meniscus is a crescentic, almost semi-circular shaped fibrocartilage disc found on the tibial plateau within the knee joint. Its proximal surface is concave and articulates with the convex-shaped femoral condyles, whilst the distal surface is flat and sitting on the articular cartilage of the tibia, covering almost two thirds of its ...
The medial meniscus is a crescent-shaped fibrocartilaginous band that articulates inferiorly with the medial condyle of the tibia and superiorly with the medial condyle of the femur, occupying approximately 60% of the contact portion of the medial compartment.
