Knee Arthritis Information
Knee arthritis is very common among all the sections of the population, but more so among the elderly. The probability of knee arthritis increases after the age of 40 and substantially increases after 70. If you are overweight or obese, extra body fat puts unneccesary pressure on your bones and especially your knees.
Arthritis is a painful condition that affects the joints of the body and causes them to swell. Your knees are often the first to be affected.
There are various types of arthritis but the type that affects the knee is known as osteoarthritis. The disease affects the cartilage in the knee and over time slowly wears the bones, muscles and the tendons in the joints. When the cartilage is destroyed, this causes friction between the bones which in turn causes swelling and pain. In some cases the pain and discomfort can be so acute that it can render the individual helpless and immobile.
The cartilage also distributes the load and minimizes stresses to the body. To remain healthy, cartilage gets nutrition from the fluid between the joints. When the levels of this fluid go down, the cartilage loses its nutrition source which makes it weaker. It is almost impossible for the cartilage to repair itself.
Options available for knee arthritis include physical therapy; regular exercises; pain mediction; walking aids; cortisone injections; knee osteotomy and knee surgeries.
