What to do if the kneecap is habitually dislocated?

Let’s first understand joints from a scientific perspective:

Joints are where bones connect to each other. Joints are composed of joint capsules, articular surfaces and joint cavities. There are many muscles attached around the joints. When the muscles contract, they can perform movements such as extension, flexion, outer layer, adduction and rotation.

1. Articular surface: The smooth surface where the bones contact each other is called the articular surface. The joint surface is covered by a layer of cartilage called articular cartilage.

2. Joint capsule: It is composed of connective tissue and is attached to the central surface around the joint surface.

3. Joint cavity: It is the narrow gap enclosed between articular cartilage and joint capsule. Normally, there is a small amount of fluid in the joint cavity to reduce friction during joint movement. When joints are diseased, fluid in the joint cavity can increase, causing joint effusion and swelling.

The reason why the human body can move freely is because of the structure of joints. Most joints not only provide the needs for human movement, but also protect the bones from wear and tear through cartilage. 65% to 80% of the cartilage is It is composed of water, and other components include glycoproteins, collagen and cartilage cells, which provide healthy nutrition and functional protection for cartilage. In fact, cartilage itself is a porous structure. Collagen is a network of slender fibers. Glycoprotein is an elastic sphere filled with water. These components must be complete in order for the cartilage to bear gravity. , if the collagen becomes less, the connection between the glycoprotein and the collagen network will loosen, or if the glycoprotein content is reduced, the glycoprotein will no longer be elastic, which will cause the joints to easily accelerate wear and tear when stress is applied, and then the joints will wear out. As patients age, these materials "naturally disappear" or "function deteriorate", forming what is called degenerative arthritis. Therefore, seniors, menopausal women, those who exercise excessively, suffer fractures or those prone to joint pain should eat more foods rich in collagen.

Factors that induce joint problems:

1. Age/aging: Those over 45 years old are prone to arthritis. As we age, the articular cartilage gradually wears and destroys, exposing the bones. This causes joint friction, inflammation and pain. The resorption and synthesis repair mechanisms of joint tissue are out of balance, resulting in the development of bone spurs or osteophytes. It is estimated that the number of patients with arthritis worldwide will exceed 800 million in 2025, second only to cardiovascular-related diseases. There are currently about 150 million arthritis patients in China. As the population ages, the number of sick people will continue to increase.

Among people over 55 years old:

* 1/4 have knee pain for nearly one month every year

* 50% have X-ray symptoms

p>

* 50% have difficulty moving (estimated to increase by 66% in 2020)

* 1.6% have disabilities

2. Gender: Women are more susceptible to arthritis than men

p>

3. Inherited gene defects: cartilage collagen gene defects lead to cartilage degeneration

4. Physical activity: joint damage caused by labor or excessive exercise; knee tendon or meniscus damage can cause knee Arthritis; Repetitive use of certain joints can cause arthritis.

The incidence of arthritis caused by various sports:

* Nearly 50% of retired football players have toe arthritis

* 48% of high jumpers and 85% of ballet dancers have ankle arthritis

* In one report 100% of football players and 90% of weightlifters had early symptoms of arthritis

* 100% of javelin throwers Athletes and 90% of gymnasts and divers have problems with their lumbar spine

* Field athletes (such as shot put, etc.) and basketball players often have problems with their shoulders

* 90% of weightlifters Problems will occur in the elbow joints of javelin throwers and boxers

* Research shows that daily activities such as climbing, running, cycling, playing badminton, and going down stairs will cause varying degrees of wear and damage to the joints

5. Weight/Obesity: Weight gain in middle-aged and elderly people can easily cause knee arthritis

6. Food/Nutrition: Certain ingredients are missing from food

Self-diagnosis of joint diseases:

The first three steps

1. Pain when starting exercise

2. Pain when there is pressure

The next three steps

1. Continuous pain

2. Pain at night

3. Muscle pain

In addition, there are also typical accompanying symptoms, such as:

1. Restriction of movement

2. "Clicking" sound from the joints

p>

3. Weather sensitivity, etc.

Treatment of osteoarthritis:

Osteoarthritis is a degenerative disease , there is currently no method that can cure osteoarthritis!

Treatment goals: slow down symptoms and progression

Treatment goals: relieve pain, increase joint range of motion, and enhance muscle strength

Treatment methods : Surgical treatment, non-surgical treatment

Surgical treatment: Replacement of artificial joints. All joints are made of metal and plastic, which are very expensive and may cause failure and disability

Non-surgical treatment :

* Physical therapy: acupuncture, infrared rays

* Exercise therapy: swimming, Tai Chi

* Drug therapy: Drug therapy can only alleviate superficial symptoms, but cannot To prevent the development of osteoarthritis, there is currently no drug that can completely cure osteoarthritis. (Although most drugs can relieve or reduce the pain of patients with osteoarthritis on the surface, they actually promote the degradation of articular cartilage.)

Nonsteroidal anti-inflammatory drugs (NSAIDs) and Painkillers:

Serious side effects

Stomach discomfort, gastrointestinal ulcers or bleeding

Inhibit the synthesis of articular cartilage matrix proteoglycans and accelerate articular cartilage degeneration< /p>

Aspirin, salicylic acid, phenylbutazone, indomethacin and naproxen, etc.

Can induce kidney damage, especially those with existing kidney disease, heart failure, liver function Insufficiency, hypertension, patients taking diuretics or angiotensin-converting enzyme inhibitors, and elderly patients, etc.

Acetaminophen, diclofenac, meloxicam, nabumetone, sulindac etodolac acid, acemetacin, celecoxib, rofecoxib, etc.

(Recent research shows that the number of deaths or toxicological effects caused by the use of coxib drugs in the United States alone reaches 140,000 More)

* Nutritional therapy: Nutritional therapy can prevent or slow down cartilage degeneration and is the best way to protect and maintain joint health.

Natural cartilage protectant: a natural substance that can slow down cartilage degradation and promote the repair and remodeling of cartilage tissue

Mechanism of action: Promote the formation of chondrocytes; promote the synthesis of cartilage components by chondrocytes, such as Hyaluronan, chondroitin sulfate, etc.; inhibit the action of cartilage-degrading enzymes; strengthen and improve the nutritional supply of cartilage; reduce inflammation and relieve pain; inhibit thrombosis and improve blood circulation

Commonly used chondroprotective agents: glucosamine, Chondroitin sulfate, hyaluronan, type II collagen, vitamins, mineral elements

Natural joint protectant:

In recent years, a kind of called "Rungujin" all-natural joint protectant is accepted by more and more professional athletes and people with bone and joint problems as daily health care and rehabilitation treatment. "Rungujin" uses all-natural high-quality raw materials and is processed using the world's advanced patented small molecule biotechnology, making it bioactive and easy for human body to absorb. It does not add any hormones and chemical additives, and has also passed the Austrian Food and Drug Administration. Doping testing by the organizing committee.

Medicinal supplements are not as good as dietary supplements, you should try it too!
