Osteoarthritis is a joint disease that mostly affects cartilage. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to glide over each other. It also helps absorb shock of movement. In osteoarthritis, the top layer of cartilage breaks down and wears away. This allows bones under the cartilage to rub together. The rubbing causes pain, swelling, and loss of motion of the joint. Over time, the joint may lose its normal shape. Also, bone spurs may grow on the edges of the joint. Bits of bone or cartilage can break off and float inside the joint space, which causes more pain and damage.
There is no cure for rheumatoid arthritis. But recent discoveries indicate that remission of symptoms is more likely when treatment begins early with strong medications known as disease-modifying antirheumatic drugs.
Infective Arthritis is otherwise known as purulent or septic arthritis. It is a condition characterized by infection of the joint by microorganisms leading to arthritis. This is a condition which is most commonly seen in people having artificial or prosthetic joints. It has to be treated as an emergency as it may lead to permanent joint pain (or) damage or systemic bacterial infection if left untreated.
Post traumatic ankle arthritis is exactly what it sounds like—arthritis that occurs after trauma to the ankle. It’s characterized by damage to the ankle’s cartilage that develops following an injury, such as a fracture or severe ankle sprain. Although it is most common after injuries that damage the joint surface, any injury to the ankle can be theculprit.
Like osteoarthritis, posttraumatic arthritis occurs when the smooth cartilage covering the surfaces of the joint begins to thin and erode, eventually resulting in bone rubbing on bone. Unlike osteoarthritis, which normally takes decades to develop, posttraumatic arthritis can develop over a much shorter period of time. It may take years, but sometimes it develops in mere months.
