Anatomy of Torn Cartilage and Other Knee Accidents3562768

The human knee is a very complicated joint. Two main bones arrive with each other at the knee -- the femur (thigh bone) and the tibia -- (shin bone). There is a third bone found at the knee -- the patella (knee cap), but it does not participate in the joint between the femur and the tibia tibia wt. The lower stop of the femur has two made to match into the concave surfaces on the tibia. But there are a number of things found in in between.

Very first of all, the two the lower stop of the femur and the upper stop of the tibia are lined with a layer of cartilage, known as articular cartilage. Secondly, there are two ring-like pads of cartilage inserted amongst the articular cartilage of the femur and the articular cartilage of the tibia. One of these is found in between the curved surfaces on the medial side (nearer to the midline of the entire body) of the knee and is known as the medial meniscus. The other one particular is found amongst the curved surfaces on the lateral facet (farther from the midline of the human body) of the knee and is named the lateral meniscus. Thirdly, there is synovial fluid lubricating all of these cartilage surfaces.

There are also a lot of ligaments linked with the knee. Ligaments are cords of connective tissue which pass from one particular bone to an additional throughout a joint. Their operate is to make the joint more robust. Two of these knee ligaments type an X in the area amongst the medial meniscus and the lateral meniscus. They are named cruciate ligaments, from the latin word for an X. The anterior cruciate ligament (ACL) commences on the center of the front of the tibia and attaches around the again of the femur wt tibia. The posterior cruciate ligament (PCL) starts near the center of the again of the tibia and attaches in close proximity to the front of the femur.

Two other ligaments of the knee are known as collateral ligaments. The medial collateral ligament (MCL) begins on the medial aspect of the femur and attaches on the medial side of the tibia. The lateral collateral ligament (LCL) begins on the lateral aspect of the femur and attaches on the lateral facet of the tibia. Two a lot more knee ligaments are known as popliteal ligaments. They the two start on the again of the femur and provide toughness to the back again of the knee. The patellar ligament begins at the patella (knee cap) and attaches to the entrance of the tibia. It provides energy to the front of the knee. There are also other ligaments connected with the knee.

A single variety of knee injuries is known as a torn cartilage. This refers to a tear in either the medial meniscus or the lateral meniscus. The medial meniscus is considerably far more probably to be torn than the lateral meniscus. The explanation for this is that the medial collateral ligament (MCL) is actually attached to the medial meniscus. The anterior cruciate ligament (ACL) is also hooked up to the medial meniscus. If the knee is hit from the side or twisted, the pressure pulls on the medial collateral ligament (MCL), which in turn pulls on the medial meniscus, which in turn pulls on the anterior cruciate ligament (ACL). As a result, the 2 ligaments may possibly stretch or tear. Given that the meniscus is composed of cartilage, it cannot extend so it tears.

A torn lateral meniscus is significantly significantly less likely to happen, but it is not not possible. The lateral meniscus tibia world trade is not attached to the lateral collateral ligament (LCL), but it is attached to the posterior cruciate ligament.

An additional variety of knee damage is a dislocation. This refers to a circumstance in which the higher conclude of the tibia is pushed out of its standard situation, directly beneath the reduced end of the femur. The tibia could be displaced in any course -- ahead, backward, to the medial aspect, or the the lateral facet, or it could be twisted in area. With a dislocation, there is the likelihood of harm to any of the constructions connected with the knee or to any of the blood vessels in the knee area.
