Knee Arthritis Q & A

What is knee arthritis?

Arthritis isn’t just one condition; there are over 100 different types, all causing long-term pain and often disability. 

The knee joint forms where the end of your upper thigh bone (femur) meets the top of the lower leg bone (tibia). There’s also the kneecap (patella), a piece of bone at the front of your knee.

To stop these bones from rubbing against each other, they have protective articular cartilage covering them. The joint also has synovial fluid that lubricates the area, like oil in an engine. Arthritis develops when something happens to the joint’s protection.

The result is chronic pain that can flare up and become excruciating. The knees also get weak, stiff, and swollen. They may twist and distort with advanced arthritis.

What causes knee arthritis?

Osteoarthritis is the form of arthritis most likely to affect your knees. It’s the disease that causes painful, twisted joints in old age, although it typically begins in middle age. 

Over the years, the smooth, tough coating of cartilage gradually wears away. The bone underneath is exposed, so friction builds up as you move. The exposed bone deteriorates, creating pits that worsen the friction. 

Other forms of arthritis that are common in the knees include rheumatoid arthritis and psoriatic arthritis. These conditions are both autoimmune disorders, which means they arise because of a flaw in your immune system. This flaw causes your body to attack cells in your joints, destroying the joint linings.

How is knee arthritis treated?

Unfortunately, arthritis is incurable, but there are many ways to reduce pain and improve your mobility. Knees First specializes in using nonsurgical treatments for knee arthritis. 

In the early days, most patients can effectively manage knee arthritis symptoms through a combination of physical therapy, medication, and activity modification. You might need to use assistive devices like a brace or supportive knee sleeve, and ice or heat and pain relief creams may help.

As time passes, these approaches may be less effective, and your provider at Knees First can offer additional, cutting-edge therapies. 

Platelet-rich plasma (PRP) and stem cell injections promote healing and new tissue growth. Hyaluronic acid injections contain a lubricant that helps the bones slide over each other inside the joint. 

If you have knee arthritis, start treatment early to delay joint deterioration. Call Knees First today or book an appointment online.
