What type of arthritis developes when joint cartilage wears out?
All arthritis involves the destruction or wearing of joint cartilage, However the form of arthritis that is described as the wear and tear joint disease is known as osteoarthritis.
What disorder wears out cartilage at the end of bones?
Osteo Arthritis.
What happens if arthritis destroys cartillage in a joint?
then the joint has no cartilage. Cartilage is a tough low friction coating that covers the bone where they form joints it has no nerves that can sense pain. However once it is gone the bone begins to rub directly against bone. Bones do feel pain when damaged. as the bone wears away at its opposing bone in the joint it begins to try and repair itself and that creates ridges or lipping that cause more pain and stiffness in the joint this process can be accompanied by inflammation leading to deformity surrounding the joint.
What is acromioclavicular arthritis?
it is arthritis in the shoulder joint, the collarbone (clavicle), the shoulder blade , and the arm bone . The scapula and clavicle form the socket of the joint The humerus has a round head that fits within this socket. The end of the scapula is called the acromion, and the joint between this part of the scapula and clavicle is called the acromio-clavicular joint, or AC joint. When this joint wears thin, it is called acromioclavicular (or AC) arthritis.
How does arthritis affect any bones?
Arthritis is usually the result of cartilage being gone for one reason or another. what happens at that point is that bone wears directly on bone and this in itself is painful. However as the bone wears away then it attempts to replace the bone that is being worn away this leads to deformity of the bone around the joints and lipping or the formation of access bone all around the points of contact. This stiffens the joint and restricts movement yet further and all of this is accompanied by pain .
What is bilateral patello-femoral degenerative?
Patellofemoral arthritis may be a process leads to its degeneration. Patellofemoral arthritis may occur when the artcular cartilage along the troclear groove and on the underside of the patella wears down and become inflamated. When the cartilage wears away it becomes frayrd and when the wear is severe, the underlying bone may become exposed. Movement of the bones, along this rough surface is painful. There may have oedema.
What does hypertrophic osteoarthritic mean?
Commonly known simply as osteoarthritis (OA) which is a degenerative joint disease (DJD) where joint cartilage wears away causing pain, swelling, limited movement and muscle weakness around the afflicted joint.
How young can a dog get arthritis?
Dogs can get arthritis at any age, but the cause varies. In puppies (less than one year of age), the cause tends to be infectious - bacteria get into the blood stream and then cause arthritis in multiple joints. In young dogs (older than puppies, younger than senior dogs), the cause tends to be autoimmune disease - the dog's own immune system starts attacking the tissues of the joint, resulting in arthritis. In older dogs, the cause tends to be degenerative - the cartilage and joint fluid wears out and isn't replaced, resulting in arthritis from the exposed bone ends rubbing against each other.
What is the origin of osteoarthritis?
Articular cartilage, is responsible for the low friction and painless, articulation of synovial joints. Articular cartilage consists of a sparse distribution of highly specialized cells known as chondrocytes. These are are embedded in a matrix to provide articular cartilage withwonderful mechanical properties. Chondrocytes make up the tissue matrix macromolecular framework from three classes of molecules known as collagens, proteoglycans, and noncollagenous proteins. The Chondrocytes protect the cells from being damaged as a result of normal joint use, they determine the types and concentrations of molecules reaching the cells, acts as a mechanical signal transducer for the cells, and helps maintain the chondrocyte phenotype. Articular cartilage undergoes internal remodeling Throughout life as cells replace matrix macromolecules lost as a result of degradation. Aging decreases the ability of chondrocytes become less able to maintain and restore articular cartilage leading to an increase in the risk of degeneration of the articular cartilage surface. Progressive degeneration of articular cartilage leads to joint pain and dysfunction. This situation is clinically identified as osteoarthritis. Investigation regarding the pathogenesis of post traumatic osteoarthritis, the form of osteoarthritis that develops following joint injury, is helping to explain the development and progression of joint degeneration.
Can you get arthritis after dislocation of the patella?
After any serious joint damage you contribute to the chance of getting osteoarthritis. "Osteoarthritis occurs when the cartilage that cushions the ends of bones in your joints deteriorates over time. The smooth surface of the cartilage becomes rough, causing irritation. Eventually, if the cartilage wears down completely, you may be left with bone rubbing on bone - causing the ends of your bones to become damaged and your joints to become painful."

What condition develops in older people as their cartilage wears down?
osteoporosis
Does rheumatoid arthritis affect ones muscles?
Yes it can cause muscular atrophy as the joints near the muscles become harder and more painful to move there is less reliance placed on the muscles concerned. Also the inflammation and in certain place damage to bone can cause enterprises being put on nerves that are required to control muscles. Untreated this can also lead to muscular atrophy and nerve damage.
