The knee is one of the largest joints in our body. It carries the whole body’s weight and helps us to stand, to run, to walk. This joint is made up of three bones i.e. femur, tibia and patella. These are attached with a capsule of joint, and different ligaments in and around the joint. At the end of each bone, there is cartilage which helps in preventing friction between two bones. Prevention is possible with using Dona products for joint health. There is also a jelly-like liquid inside the joint called synovial fluid.
Osteoarthritis (OA) of the knee is characterized by pain and limitation of joint movements. It considerably affects the quality of life. Degeneration, decay, and injury of articular cartilage is the hallmark of the pathologic process of osteoarthritis of the knee. There is also subchondral sclerosis, enlarged joint margin, and decay of subchondral bones. Reduction of joint space as seen in x-ray because of the reduction of cartilage height and growth of small pieces of bone-in and around are commonest observations. There will be crackling sounds on the movement of joint. Causes of pain in osteoarthritis of the knee are several, however, inflammation and sensitization of nerve ending are the most important of all mechanisms.
