what is the difference between a torn cartilage and a torn meniscus?

The articular cartilage forms the smooth layer of the joint that covers the bone ends. A layer of articular cartilage covers the end of the thigh bone, the top of the shin bone, and the back of the kneecap. The meniscus is a different type of cartilage that forms a shock absorber between the bones.

Degenerative conditions such as osteoarthritis can also cause meniscal tears. A meniscus tear can cause pain and swelling. It may be difficult to move your knee over its full range of motion, and your knee may feel locked in a certain position. These restrictions on movement lead to stiffness in the knee.

The key difference between arthritis and bursitis is the anatomical structures that they affect. Arthritis is a chronic condition that irreparably damages bone, cartilage, and joints, whereas bursitis is a temporary condition that involves the painful swelling of bursae for a time. Pain is worst in the morning.

Osteoarthritis (OA) This keeps them from rubbing together. But cartilage can wear away over time or after an injury. When it's gone, the bones hit one another, and sometimes, tiny pieces break off. The result is a stiff, swollen, painful joint.

Fibrocartilage should be accounted as a transitional tissue between hyaline cartilage and dense regular connective tissue such as tendons and ligaments [17]. ... In contrast to hyaline cartilage, fibrocartilage contains high levels of type I collagen in addition to type II and only a small component of ground substance.

PCL tears make up less than 20% of injuries to knee ligaments. Injuries that tear the PCL often damage some of the other ligaments or cartilage in the knee, as well. In some cases, the ligament can also break loose a piece of underlying bone.

Typically, piercings located in cartilage will bleed more than piercings in soft tissue, like eyebrows. Cartilage does not have its own blood supply, so the tissue surrounding the cartilage helps the initial healing process by providing blood flow to the area.

Hyaline cartilage is a translucent white type of cartilage present in areas of the body such as the joints. The main difference between this type of cartilage and elastic cartilage is that elastic cartilage contains many elastic fibers, whilst hyaline cartilage contains a matrix of mainly collagen fibers.

Ligaments and tendons are both made of connective tissue and both can be torn or overstretched, but they differ in function. Ligaments attach one bone to another. Tendons attach a muscle to a bone.

A sprain is a stretch or tear in a ligament. Ligaments are bands of fibrous tissue that connect bones to bones at joints. A strain is also a stretch or tear, but it happens in a muscle or a tendon. Tendons link muscles to the bones.

Cartilage and Bone are specialised forms of connective tissue. They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces.

Your ACL and MCL are both ligaments in your knee. The two ligaments connect your femur (thigh bone) to your tibia (shin bone) and protect the menisci that cushion the knee joint.

Hard tissue is usually referring to bones, while soft tissue refers to muscle, ligaments, tendons, or connective tissue. Hard tissue damage can affect any bone in the body, including the head or spine.

X-ray. It won't show your MCL, but it can show whether you have a broken bone. Stress X-ray. Although X-rays show bones and not soft tissues like ligaments, your doctor may be able to tell whether or not your MCL is torn with a stress X-ray.

*Cells in bone are called osteocytes while cells in cartilage are called chondrocytes.

If you have cracking or popping that does cause pain or swelling, though, see a doctor. It can be a sign of: Meniscus tears. The meniscus is a rubbery C-shaped disc that cushions your knee and acts as a shock-absorber.

Osteoarthritis occurs when the cartilage that cushions the ends of bones in your joints gradually deteriorates. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone.
