Knee Osteoarthritis is a degenerative disease that causes abnormalities and degradation of the joint bones in the knee. This disease manifests in the form of pain, tenderness, locking of joints, creaking, extreme stiffness in the knee and inflammation. This disease, if not attended on the right time, may cause significant loss of cartilage which is a potent protein that lubricates the joints. It also triggers drastic pathophysiologic changes in the synovial fluid around the knees. Further research has revealed that this condition severely deteriorates the mobility of subchondral bone as well as the encompassing joint capsule in the knee.

This disease is characterized by the reduction in the concentration of hyaluronic acid around the knee which increases the levels of pain. It causes immense inflammation in the tissues around the knee area which leads to an elevated presence of water. This disease does not affect young people and only attacks middle age and above age groups. Knee Osteoarthritis is classified into two types, namely, primary Osteoarthritis and secondary Osteoarthritis. The primary form is a degenerative disorder that causes the cartilage to become least resilient. The secondary form is an outcome of a congenital disorder that causes immense stiffness in the knee.
