Aging is not the main cause of knee pain.


Do you feel that going up and down the stairs is difficult after you are over 50?

Generally, knee pain is considered aging. Of course, that's not all, but anyway, there are a lot of middle-aged women who suffer from knee pain.

Let's elucidate the pain of the knee today.

The knee cartilage is worn out and hurts!

In the world, the perception that knee pain is generally “gout” and “the knee cartilage is worn and hurt” has permeated.

I often see catchphrases such as “Knee cartilage component chondroitin sulfate, cure knee pain” on TV commercials.

However, the causes of knee pain vary widely and are not limited to healing by incorporating cartilage components into the body.

First of all, let's deepen our understanding of “Knee Osteoarthritis” that is said to be caused by the so-called aging phenomenon that we often hear.

On top of that, I would like to know more about what is causing knee pain.

Knee osteoarthritis

If you have a pain in your knees and go to a doctor, many of you may have been told that you have knee osteoarthritis.

What is the knee osteoarthritis often seen in commercials and magazines?

To put it simply, this is the so-called knee pain that occurs when the cartilage of the knee joint is worn. It is said that when the cartilage of the knee becomes distorted or the gap between the knees narrows, the cartilage collides and pain occurs.

That was the one I mentioned at the beginning: “Knee cartilage is worn out and hurts.”

This “Knee Osteoarthritis” is the most common disease of the elderly knee.

Statistically, it is said that 25 to 40% of people in middle-aged and older age groups have this knee osteoarthritis regardless of the presence or absence of symptoms.

As mentioned above, osteoarthritis of the knee is mainly composed of degeneration (deformation due to aging) and wear of articular cartilage, and 90% have no history of trauma or infection.

Knee pain is not the main cause of aging !?

Until now, degeneration of joints due to “aging” and degeneration of articular cartilage due to “osteoarthritis of the knee” have been considered the same. It seems so because knee osteoarthritis is more common in the elderly and there are more severe cases in the elderly.

However, research in the United States has revealed that this is actually due to damage caused by accumulation of loads (such as weight and center of gravity) and a decrease in the healing power to cure the damage.

Research in osteoarthritis of the knee is progressing in Japan, and the recognition that it is not due to aging but not unavoidable. Rather, from the new viewpoint that the abnormality of the cartilage matrix (the basic component that makes cartilage) is a problem, the search for a method to cure the cartilage matrix began.

As a result, it became clear that the cartilage degeneration in osteoarthritis of the knee can be delayed, stopped and prevented.

The point is how to keep the flexible cartilage in a normal state. And when you get older, how to efficiently take in the cartilage component, whose synthetic ability in the body falls.

Chiropractic and supplements will play an important role !

Among the patients who come to me, there are many people who have knee pain in their 40s and 50s, and it is difficult to cure. It is also related to weight gain and falling body metabolism…. Let's share that story at another time.

The cause of knee pain is really deep. Please consult us.
