Bursitis of the Knee:
Tiny sacs of fluid cushion the bones in the knee joint. When they become infected or irritated, they can become inflamed, leading to a condition known as bursitis. This painful condition may be accompanied by redness around the joint, tenderness at the knee and in some cases, fever.
Tendinitis of the Knee:
Tendons are the tissue that binds muscle to bones, and tendinitis is common in the knee. It’s characterized by a dull ache in the knee that increases with use. It may become swollen or painful. In some cases, rest alone can combat tendinitis, but severe cases require medical intervention.
Also known as a popliteal cyst, a Baker’s cyst is a fluid-filled swelling at the back of the knee. Because of the swelling, it can restrict movement. It can be a sign of an un diagnosed knee injury. In many cases, a popliteal cyst will go away on its own. Sometimes, fluid may need to be drained from the cyst.
Inflammation and swelling of the knee joint itself, this condition is caused by the deterioration of the knee. It can be caused by past injury, poor posture, age or obesity.
Rheumatoid Arthritis (RA):
This autoimmune disease is similar to osteoarthritis, but is often not localized to a single joint, and is indicated by stiffness, swelling and pain.
