Osteoarthritis

Osteoarthritis (OA) is a wear and tear condition that is one of the most common causes of knee pain with age. Osteoarthritis is caused by wearing down of the cartilage that lines the bones of a joint. Healthy cartilage is smooth and slippery. After trauma, such as surgery or injury, or just as part of the natural process of aging, the smooth surface of the cartilage can become rough, irregular, and thinned out. This process can cause inflammation and is often associated with swelling and bony outgrowths on the sides of the joint called “bone spurs.” Symptoms associated with osteoarthritis can include pain with activity on the inside, outside, or front of the knee. Decreased range of motion, or inability to fully bend or straighten the knee, is another common symptom. Osteoarthritis can occur in one, two, or all three compartments of the joints:

  • Medial (inside)
  • Lateral (outside)
  • Patellofemoral (under the kneecap)

Inflammatory Arthritis Knee Pain

There are other types of arthritis that can affect the knee joint as well, known as inflammatory arthritis. These conditions are frequently caused by autoimmune disorders or other types of systemic inflammatory problems. There are many different types of inflammatory arthritis and these conditions are treated by rheumatology doctors. Inflammatory arthritis usually involves many joints in the body, causing pain, redness, and swelling. Rheumatoid arthritis is one type of inflammatory arthritis. Gout or pseudogout are also considered inflammatory types of arthritis and are caused by crystal deposits in the knee. Your doctor can help distinguish among these types of conditions by using a needle to take a sample of your joint (synovial) fluid and sending it for laboratory analysis.
