What is osteoarthritis (OA) of the knee?
OA is a painful degenerative condition that develops as the meniscus (cushioning cartilage in the knee joint) and/or the articular cartilage (soft, outer lining of the bones) begin to wear away. OA usually appears on one side of the knee, and affects both men and women across a broad age range.
What causes knee OA?
A variety of conditions can lead to knee OA. A previous knee injury or surgery that partially or entirely removed the meniscus from the knee is a common cause. Simple wear and tear of the knee joint occurring from years of activity can also be a factor.
What causes OA pain?
OA pain results from a deterioration or loss of cartilage. Pain is generally localized on the inside of the knee. Depending on the progression of the disease, the joint space may become small enough to allow the two bones to touch, causing pain.
Do I need knee surgery?
In the early stages of symptoms, a conservative approach is thought to be best. However, based on your history, symptoms, and the amount of degenerative change in your joint, your physician will determine the optimal treatment for you.
What are some non-surgical options?
Off-loading knee bracing is considered one of the best treatment options. Injections (visscosupplimentation or joint fluid therapy), non-steroidal anti-inflammatory drugs (NSAIDS), supplements, strength and conditioning, including weight loss, and heel wedge insoles may also help reduce OA pain, especially when used in conjunction with bracing.
How effective is OA bracing in treating pain?
Knee bracing is proven highly effective in relieving OA symptoms. Studies suggest that the majority of OA patients using braces report significantly reduced pain, increased activity levels, and a substantial reduction in the use of oral pain medications.
