Answer 1

Hello,

Read this::

While often referred to as if it were a single disease, arthritis is actually an umbrella term used for a group of more than 100 medical conditions that collectively affect nearly 46 million adults and 300,000 children in America alone. While the most common form of arthritis - osteoarthritis (OA) - is most prevalent in people over 60, arthritis in its various forms can start as early as infancy. Some forms affect people in their young-adult years as they are beginning careers and families and still others start during the peak career and child-rearing years.

The common thread among these 100-plus conditions is that they all affect the musculoskeletal system and specifically the joints - where two or more bones meet. Arthritis-related joint problems include pain, stiffness, inflammation and damage to joint cartilage and surrounding structures. Such damage can lead to joint weakness, instability and visible deformities that, depending on the location of joint involvement, can interfere with the most basic daily tasks such as walking, climbing stairs, using a computer keyboard, cutting your food or brushing your teeth.

For many people with arthritis, however, joint involvement is not the extent of the problem. Many forms of arthritis are classified as systemic, meaning they can affect the whole body.

In these diseases, arthritis can cause damage to virtually any bodily organ or system, including the heart, lungs, kidneys, blood vessels and skin. Arthritis-related conditions primarily affect the muscles and the bones.

Replacement of parts:

The materials used in artificial joints vary, depending on the type of joint being replaced and how the joint needs to function. Hip joints, for example, need to be sturdy and able to bear your body’s weight. Knee joints need to be flexible as well as strong, while finger joints must be capable of bending easily. In general, the components must be durable, flexible and able to function in the body without causing an immune system reaction.

Replacements for hip and knee joints include portions made from metal, such as stainless steel, titanium or chrome and cobalt alloys. Other potions are made of a strong, durable plastic called polyethylene.
