Do you feel knee pain when you go up and down stairs and squat? Does your knee feel sore after strenuous exercise? This may be chondromalacia patella, it is a common orthopedic disease, frequently occurring, the main symptom is knee pain

.

One minute self test, how’s your knee? There are three movements that can be used for simple self-test of our knee health, and the difficulty is from difficult to easy: if the above prompt situation occurs during the movement, it is recommended to go to the hospital in time, and the diagnosis can be made through “patella grinding test”

.

What is patella malacia? In fact, it’s not really osteomalacia

.

To be exact, it’s called chondromalacia patellae, commonly known as chondromalacia patellae

.

Patellar cartilage is a signal lamp of “knee aging”

.

Once injured, chondrocytes function is abnormal and cannot exchange nutrients normally, leading to chondrocytes degeneration and necrosis, and then focal softening, fibrosis and cracking will appear

.

What symptom does patella malacia have? ● pain

.

This is the initial symptom

.

Pain occurs after exercise or mountain climbing

.

After a little activity, the pain can temporarily disappear

.

After a long time of activity, it will reappear

.

Then when you go up and down stairs or walk, or have a specific angle, you will feel pain, even serious to rest pain or night pain

.

In the early stage, it is the pain of acid swelling, and some people say it is dull pain

.

In the later stage, it will become a tingling feeling when it gradually worsens

.

● sound

.

During the flexion and extension of the knee joint, there is often a bounce under the patella

.

Severe patients can hear the rustle

.

● swelling

.

Because of the inflammation inside the joint, the synovium secretes a lot of fluid, showing swelling of the knee joint

.

Soft

.

It is often said by the common people that they can’t get enough strength and have soft legs

.

It often appears when they get up in the morning, go down the ground and climb the stairs

.

In fact, it is cartilage that has been damaged and degenerated to varying degrees

.

Fine

.

Patella softening can cause quadriceps muscle atrophy, weakness, so the appearance of the thigh will become thinner

.

Does running hurt the knee or not? Running is not a direct injury to the knee and hip

.

Only by controlling the quality, quantity and correct posture can we run healthily

.

Although running is the most popular sport, it is not suitable for all people, such as obese people, people with varus (O-shaped leg) or valgus (X-shaped leg) deformity of knee joint, and people with previous injury of knee ligament or meniscus and other important structures

.

In addition, climbing canes can be reasonably used to cooperate with hiking to reduce the pressure of body and equipment load on feet and knees and cartilage wear

.

Cane height is usually calculated by multiplying height by 0.66

.

Sedentary, more knee injury? Many people think that exercise is more or less harmful to the knee joint

.

They simply don’t exercise to reduce joint wear

.

They think that this can protect the joint

.

In fact, this is a misunderstanding

.

Articular cartilage is not renewable, it has no innervation, no blood supply, but it also needs nutrition

.

The main nutrition comes from synovial fluid

.

There are about 1-2ml synovial fluid in normal knee joint

.

When the joint moves, the cartilage is compressed and deformed, and the synovial fluid is squeezed in, thus the cartilage gets nutrition

.

If you don’t move for a long time, this kind of pressure infiltration disappears, the synovial fluid in the joint can’t flow fully, the cartilage can’t get enough nutrition, the muscle tissue around the joint will atrophy day by day, and the risk of joint injury will naturally increase

.

How to treat patella malacia? ● oral drugs: the first category is glucosamine cartilage nutrition drugs, and the second category is anti-inflammatory and analgesic non steroidal anti-inflammatory drugs

.

Physical therapy: such as high frequency electrotherapy, medium and low frequency electrotherapy, wax therapy, etc

.

Fumigation method for external use of traditional Chinese medicine

.

Exercise therapy: muscle strength exercise, such as squatting against the wall
