Osteoarthritis (OA) of the Knee
Osteoarthritis (OA) is the most common type of arthritis and one of the most reported causes of knee pain. It is estimated that more than 10 million people in the U.S. alone have OA in one or both knees. Osteoarthritis is a cause of degenerative joint disease (DJD) in the knee.
If you have OA in your knee, the fluid (Synovial Fluid) that cushions and lubricates the joint can break down and lose the ability to cushion the knee. The cartilage protecting the ends of the bones can also deteriorate and then comes the dreaded saying “bone on bone” arthritis.
Osteoarthritis may be related to an injury or may develop with advancing age. Other types of arthritis may be related to infection, or an inflammation of the joint lining. There are three compartments in the knee that could develop arthritis:
- Medial compartment (the inside)
- Lateral compartment (the outside)
- Patellofemoral compartment (the knee cap region)
Your arthritis could be in one, two or all three compartments.
Symptoms of Osteoarthritis
OA will typically gradually worsen over time. Symptoms may include:
- Pain during movement and/or at rest
- Grinding, popping, catching sensations in the joint
- Giving way when walking
- Stiffness and Joint swelling
- Loss of motion of the knee
There are several treatment options available to you for arthritis including:
- over the counter pills such as Tylenol or anti-inflammatory medications such as Ibuprofen
