I think this helped me understand some of my issues better and my doc seems to think that may be metabolic related as well.
"Arthrosis has two definitions – one anatomical (part of the body) and one pathological (disease).
Arthrosis is the term for any joint in the body(Greek ~arthros). A joint in turn is the point where two bones meet in a manner which allows for movement (articulation). The different types of joints – ball and socket, hinge, condyloid, pivot, gliding and saddle joints – articulate in specific ways.
Arthrosis is also the term for a degenerative disease of the joint where the cartilage lining the joint erodes over time. Arthrosis is a broad term for degenerative and other diseases of the joint and is more commonly understood in the form of osteoarthritis. Therefore the term arthosis is sometimes considered to be synonymous with osteoarthritis while at other times arthrosis is seen as a prelude to or the early stages of osteoarthritis.
What is arthrosis?
Arthrosis is not a commonly used term to describe degenerative joint disease. To fully grasp the meaning of arthrosis, it is important to first understand the anatomy of the joint. The ends of bones that are part of a joint have a smooth surface known as the subchondral bone. Over it lies the articular cartilage which is strong yet flexible connective tissue that protects the bone, allows for easier movement between the surfaces and also acts as a shock absorber. It is this cartilage that is part of the articular surface and not the bone itself. The joint itself has a synovial lining (synovium) which secretes synovial fluid into the joint space that lubricates the articular surfaces and acts as a shock absorber. An outer capsule secures the joint.
Cartilage is a flexible connective tissue. The cartilage cells are known as chondroblasts which produce and release large amounts of different substances, like collagen, into the extracellular matrix. It is this matrix that is responsible for the characteristics of cartilage namely its strength and flexibility. Sometimes chondroblasts are trapped within the matrix and is then referred to as chondrocytes. The cartilage is constantly undergoing wear-and-tear. Cartilage cells, however, are constantly replenishing the cartilage matrix and therefore maintaining the integrity of the cartilage.
With age, the ability to replenish any tissue diminishes but does not cease altogether. Even in younger people, the body’s ability to replenish tissue is limited by time. If there is constant and excessive wear and tear of the articular cartilage which exceeds the replenishing time, then the cartilage will erode. This is the reason why arthrosis is more commonly seen in the elderly (in my case maybe metabolic syndrome😖) and more frequently in those who are very active. There are also other factors that further complicate this like inflammatory mediators which affect normal cartilage regeneration although there is little or no inflammation of the joint. Similarly if there is some underlying disease which slows or stops the activity of the cartilage cells, the cartilage will eventually wear out. As it weakens, bits of cartilage break off and float around in the joint space. The bone tissue is now exposed to the same wear and tear as the articular cartilage but lacks the flexibility and regenerative capability. It is then destroyed over time and this condition is known as osteoarthritis."
