What is fibrillation cartilage?

Human articular cartilage can develop areas of fibrillation. In such areas there is fraying and splitting of the cartilage, frequently accompanied by its local disintegration and erosion.

What is the meaning of fibrillation?

Fibrillation: In cardiology, an abnormal and erratic twitching of the heart muscle.

What does articular cartilage mean in medical terms?

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.

What causes thinning of articular cartilage?

Cartilage structures and functions can be damaged. Such damage can result from a variety of causes, such as a bad fall or traumatic sport-accident, previous knee injuries or wear and tear over time.

How is articular cartilage damage treated?

Surgery is often the best treatment option for damaged articular cartilage since it does not heal well on its own. Some surgeries aim to relieve symptoms, while other surgical procedures are intended to repair and restore damaged articular cartilage.

Why is fibrillation a bad thing?

Although atrial fibrillation itself usually isn’t life-threatening, it is a serious medical condition that sometimes requires emergency treatment. A major concern with atrial fibrillation is the potential to develop blood clots within the upper chambers of the heart.

What is the most common cause of atrial fibrillation?

Most common causes leading to atrial fibrillation include heart valve disease, heart failure, and others. Atrial fibrillation (AF) is an abnormal heart rhythm characterized by an irregular and fast heartbeat. The upper chambers of the heart (atria) beat chaotically.

What is the purpose of articular cartilage?

Is walking good for knee cartilage?

When the joints bear weight via any kind of weight-bearing exercise, the exercise can help rebuild the joint cartilage. Walking or weight-bearing also strengthens the bones that form the knee joint.

How long does it take to heal articular cartilage damage?

Full recovery from a microfracture technique typically takes at least 6-12 months.

How are articular cartilage lesions of the knee classified?

Articular cartilage lesions can be subdivided in various ways and into different groups. It is classified based on location of the injury or depending on the number of sites affected by the lesions. In the first subdivision, damage of the femoral condyles or tibial plateaus is distinguished from cartilage damage to the deep surface of the patella.

What do you need to know about articular cartilage?

Definitions: Articular cartilage refers to the lining of the bones in a joint (such as the knee, hip, shoulder, and wrist). It is an amazing dynamic structure that

How are collagen fibrils arranged in articular cartilage?

Of note, the collagen fibrils are arranged perpendicular to the articular cartilage. The calcified layer plays an integral role in securing the cartilage to bone, by anchoring the collagen fibrils of the deep zone to subchondral bone. In this zone, the cell population is scarce and chondrocytes are hypertrophic.

What kind of knee injury is chondromalacia patellae?

Chondromalacia patellae, also known as “ runner’s knee ,” is a condition where the cartilage on the undersurface of the patella (kneecap) deteriorates and softens. This condition is common among young, athletic individuals, but may also occur in older adults who have arthritis of the knee. Chondromalacia is often seen as an overuse injury in
