Knee arthritis is a common condition that occurs when the cartilage in the knee joint breaks down, causing pain, stiffness, and swelling. Cartilage is a smooth, flexible tissue that covers the ends of bones and helps to cushion and protect the joint. When it wears away, the bones can rub against each other, leading to pain, inflammation, and reduced mobility.
There are several different types of knee arthritis, including osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis. Osteoarthritis is the most common type and is usually caused by wear and tear on the joint over time. Rheumatoid arthritis is an autoimmune disorder that can affect any joint in the body, including the knee. Post-traumatic arthritis can develop after a knee injury or fracture.
Symptoms of knee arthritis can include pain, stiffness, swelling, and reduced mobility. Treatment options may include pain medication, physical therapy, and surgery in more severe cases. Lifestyle changes, such as losing weight, staying active, and avoiding high-impact activities, may also be helpful in managing symptoms and slowing the progression of the disease.
