Is Your Knee Pain Caused by Arthritis

Understanding the Knee

The knee joint is made up of the lower end of the femur, the upper ends of the tibia and fibula, and the patella. The ends of each of these bones are covered in cartilage which allows the bones to gently glide against one another as the knee bends and straightens.

The meniscus is made up of two wedge-shaped pieces of cartilage that act as shock absorbers between the thighbone and shinbone. Ligaments connect all of the bones together and help stabilize the joint.

Understanding Arthritis

Arthritis occurs when the joint becomes inflamed and causes pain, swelling, and stiffness. It can develop in any joint in the body, and it’s very common in the knee. The two most common forms are osteoarthritis and rheumatoid arthritis.

Osteoarthritis is a degenerative condition that typically occurs in people who are 50 years of age and older. This type of arthritis is known as a wear and tear disease and will only worsen over time. With osteoarthritis in the knee, the cartilage gradually wears away and there is no longer a buffer between the bones in the joint. This causes the bones to rub together which can be very painful.

Rheumatoid arthritis typically attacks multiple joints throughout the body. It’s an autoimmune disease, meaning the immune system attacks its own tissues like cartilage and ligaments. When rheumatoid arthritis occurs, the synovial membrane that covers the knee joint swells which leads to pain and stiffness.


Common symptoms of knee arthritis include swelling, clicking or popping, limping, and limited range of motion. It’s also common for knee pain to radiate down the leg. One clear sign of knee arthritis is if you’re experiencing the knee joint locking.

Because arthritis develops gradually, knee arthritis symptoms can progress slowly over the course of a few years. It’s important to pay close attention to the signs that your knee is giving you.

If you’re experiencing any of these symptoms, you may be dealing with arthritis in your knee. It’s best to contact your doctor immediately for an evaluation.


The doctor will perform a thorough examination to determine the source of your pain, and may order imaging tests such as X-rays or an MRI to confirm the diagnosis.


Joint injections treat many different kinds of joint pain including knee arthritis.

Supartz knee injections are a type of joint fluid therapy approved for the treatment of osteoarthritis in the knee. This drug is a clear, viscous liquid, similar to the body’s synovial fluid and is injected directly into the knee. Supartz is designed to provide long-term pain relief by supplementing the body’s natural synovial fluid. Most patients return to their normal activities immediately after the procedure and experience pain relief as early as 1-2 days after the first injection, which can last months to years.
