Because this means that even if the cartilage is seriously damaged, the human body will not feel pain, so it will not stop all kinds of behaviors that damage the cartilage.

Running is definitely recognized as the first exercise to lose weight.

In this SCI article, Professor Lequenne pointed out: “Compared with ordinary people who do not like sports, people who have running habits and exercise regularly are more likely to suffer from knee osteoarthritis.” In 2004, Felson et al.

No matter how to lose weight or how to run, it is essentially a process of changing the body by challenging and surpassing the limits of the body to get the body out of the comfort zone.

Therefore, irreversible wear is more likely to occur than other parts.

Let’s look at the professional medical literature.

Until the cartilage in some part is completely worn, exposing the bone under the cartilage.

In the morning, runners with earphones can always be seen in the community and streets.

The main reasons why obesity has become the biggest risk factor of knee osteoarthritis in runners are: on the one hand, obese people cannot effectively stabilize the knee joint and cushion the impact force due to the relative lack of strength and endurance of muscles and ligaments; On the other hand, too much weight means that the joints of lower limbs should bear too much impact and friction during running.

In 1997, Lequenne et al.

The only difference is that some injuries are temporary and reversible, for example, the biceps brachii (brachial muscle) is temporarily and reversibly injured by lifting iron in the gym to obtain a thicker arm circumference after muscle recovery; However, some injuries are permanent, irreversible, or even undetected temporarily, such as repeated wear and tear of articular cartilage in the knee caused by exercise beyond endurance.

In December 2014, two scholars, Lu Liangyu and Wang Yubin, from the Sports Medicine Department of the Oriental Hospital affiliated to Tongji University [3], published a guiding article on the Chinese Journal of Sports Medicine, entitled “The Effect of 12 Week Regular Exercise on the Volume of Knee Cartilage in Healthy Adults”..

Just a few years ago, marathons only existed on TV.

Of course, this is not the most terrible thing.

They summarized all the risk factors affecting joints into two categories: increasing joint vulnerability: such as poor joint alignment (in short, abnormal limb deformity, such as O-shaped leg or X-shaped leg), muscle weakness, aging, genetic factors, etc; Increase joint load: such as obesity, high-level competitive running, etc.

At this time, the nerves on the bones were stimulated and finally caused pain.

You may see many people on the Internet trying to wash away the running injuries.

What’s more, articular cartilage has two special anatomical characteristics: cartilage has no blood vessels, cartilage has no nerves and no blood vessels, which means that articular cartilage can only rely on joint fluid to absorb nutrition.

Some injuries are irreversible.

Therefore, the ability of cartilage to repair itself after injury is unimaginable.

Cartilage can be regarded as a cushion between bones to avoid direct friction and vibration between bones.

Unfortunately, the cartilage of the human body is as smooth and fragile as a thin ice layer.

The most terrible thing is that cartilage has no nerves.

Now, there are few friends who have ever run marathons.

[2] published an article entitled “Risk factors for osteoarthritis: understanding joint vulnerability” on the Journal of Clinical Orthopaedics and Related Research.

Running is so popular, on the one hand, due to the strong promotion, on the other hand, because running has many advantages that other sports do not have, such as low threshold, low cost, unlimited venues, simple operation, etc.

At this time, you will come to the orthopedic clinic, but the doctor told you to recommend hospitalization.

[1] published an article on the magazine Osteoarthritis and Cartilage entitled “Sports practice and osteoarthritis of the limbs”.

However, as we said before, unlike acute injuries that can appear immediately and are partially reversible, excessive impact and wear of excessive weight on knee joints are slow, hidden and irreversible, and they often do not feel uncomfortable until cartilage wear to a certain extent.

Running route data in the circle of friends has gradually replaced food and drink.

However, all sports that challenge and exceed the endurance of the body will inevitably damage one or some parts of the body to varying degrees.

However, when excessive wear of cartilage causes osteoarthritis, the damage is already irreversible, so we have to go to the orthopedics department to find a doctor to replace the joint.

But today, as an orthopedic doctor who often performs operations on others to change joints, I must say: Please stop running to lose weight! You may have run for a long time without feeling uncomfortable.

You may also lose weight successfully in the future, but more likely, you will run to the hospital earlier to change joints.

With regard to the “knee joint injury caused by running”, there were people tearing each other up in the forum, discussions among runners in the community, and even sports medical experts had different opinions.
