Normal Knee vs OA Knee: What’s Different Inside?

A normal knee functions without problems. Normal cartilage provides smooth surface so bones can move easily across each other. The “OA” knee – OA stands for Osteoarthritis – is most of the time completely worn away, eroded cartilage may cause bones to scrape painfully against each other.

So, how do you know whether you are suffering from OA? Ask yourself a couple simple questions, and you will find the answer. Are you unable to do or enjoy certain activities because of pain or stiffness in your knee? – Do you frequently experience stiffness in your knee after resting or when waking up? – And do you hear a crackling sound or have a grating feeling in your knee?

Osteoarthritis of the knee can be painful

If so, chances are you are suffering from some form of osteoarthritis. A low level of a lubricating substance (hyaluronan) in the synovial fluid that cushions your knee is most probably the cause of that pain. Without enough hyaluronan, the bones of your knee begin to rub against each other, causing erosion, bone spurs, and pain.

Common risk factors for OA of the knee are genetics, being overweight, joint injury, overuse of the joint, and having other forms of arthritis. More than ten million Americans suffer from OA of the knee. Nothing can cure OA, but it can be treated effectively with proper physician care. Many people with OA live happy, healthy, and active lives.

At our practice we implement Supartz, which is a solution made of highly purified sodium hyaluranote. It’s a natural chemical found in your body and in joint tissues and synovial fluid that fills your joints. Your body’s own hyaluronan acts like a lubricant and shock absorber in synovial fluid of a healthy joint.

Injections can help your knee

Dr. Feder uses an injection therapy of Supartz therapy into your knee once a week for three to five injections with a simple procedure that is performed in our office. It’s fast and mostly tpainfree, and it’ has proven to work well.
