Knee Arthritis: Signs, Causes, and Treatment Options

The knee is one of the largest and most complex joints in the body composed of bones, ligaments, muscles, and tendons, as well as many other structures. In 2020, a global study shows around 645 million individuals are affected by knee osteoarthritis. The condition is particularly prevalent in men over the age of 50.

Knee arthritis can be a painful and debilitating condition, but with the right treatment, it can be managed. There are many treatment options available for people dealing with knee arthritis to help them alleviate the pain and keep them stay healthy and active.

 

What is knee arthritis?

One of the most common kinds of arthritis is knee arthritis. Knee arthritis occurs due to inflammation or deterioration of the knee joint cartilage. Cartilage is a tough and flexible tissue that covers the surface of the joint which allows the knee to bend and straighten. If the cartilage is harmed or damaged, it can cause immediate problems like soreness, swelling, rigidity, or more lasting issues such as osteoarthritis. 

The knee’s main functions are to support the body's weight, facilitate movement of the leg, help lower and raise the body, act as shock absorber, allow twisting of the leg and provide stability when standing and walking.The knee joint is composed of three bones—the femur (thigh bone), the tibia (shin bone) and the patella (kneecap).
