What is the reason why the knee can t be straightened and hurts when it is straightened?

Knee extension can be caused by an old injury to the knee joint. Whether it's a periarticular fracture or an injury within an articulation, if the patient doesn't do enough functional exercises during the process, joint movement may be limited and there may be significant pain when the joint is straightened. Can be caused by joint disorders, such as meniscus, cartilage, ligament injuries, or loose body injuries in the knee.

May be caused by peripheral neuropathy. When severe sciatica occurs, the patient adopts a protective position with the lower limbs curled up. If the knee needs to be straightened, severe pain can be induced, and the patient will actively roll up the lower limbs without straightening the knee to relieve the pain.

Impaired function of the knee extension device. Knee extension is done primarily by quadriceps contraction. If the quadriceps muscle is injured or neurogenic muscle is injured, repair of the quadriceps muscle or neurogenic muscle injury** is required to normalize the knee extension device.

For severe osteoarthritis, if the osteoarthritis is severe, it affects the movement of the joint, and the knee joint cannot be straightened. Joint replacement surgery often involves correcting the force line of the knee joint so that the knee joint can be straightened. Straightening disorders can also occur because of long-term immobilization of the knee after trauma or because of fibrous adhesions in the knee.

Arthroscopic release of adhesions and restoration of knee extension are necessary. After the leg is not straight, it will lead to uneven force on the knee joint, resulting in excessive compression and friction of the knee cartilage and meniscus, resulting in knee cartilage meniscus injury and rupture, and after the leg is not straight, it will also lead to the contracture of ligaments and joint capsule adhesions around the knee joint.

This leads to a significant increase in pressure within the knee joint, which can easily cause damage to the knee joint. If there is a failure to extend the leg, it is necessary to seek medical attention in time to restore the function of the leg extension and avoid premature degeneration of the knee joint in the later stage, resulting in osteoarthritis of the knee joint and cartilage meniscus injury and fracture. The pungent smell of leeks has the effect of dispersing stasis, invigorating blood and guiding stagnation.

It is suitable for patients with trauma and joint dislocation. It can play a role in relieving pain and is beneficial to the patient's **.

Inflammation of the infrapatellar fat pad: soft tissue injuries of the knee itself, sports injuries, and some people may have exercised more recently, such as climbing and running.

Patellar tendon inflammation: over-extension may squeeze the patellar tendon and cause pain where the inflammation occurs;

This must be caused by osteoporosis, because there is a problem with my bones, so as long as I straighten it, I will feel very painful, and I must go to the hospital for surgery at this time.

It is likely that this problem is caused by arthritis or osteoporosis, or there may be some problems with the lumbar discs. You can go to the hospital for a detailed examination first, and then do **.

It may be a meniscus tear, it may be knee arthritis, or there are bone spurs in the joint, so the knee cannot be straightened, and it will become very painful as soon as it is straightened.

It indicates that there is a fracture, and it may be a tear in the anterior angle of your meniscus. There may be intra-articular adhesions.

It is pressure pain. Considering age, there is a high probability of knee degeneration. If possible, do an MRI to see if the meniscus in your knee is injured or worn, and if you often squat on your knee for long periods of time, the relieving pain behind the knee may be due to compression (meniscus hind foot).

Consider the cause of patellar subluxation. You must have injured your knee. Don't be blind.

What kind of closure will make you feel no pain. After the curative effect, it was found to be more serious than before.

<> patella strainThe patella is the fulcrum of knee extension. During knee extension, the patella needs to be pressed firmly against the posterior femoral condyle. Increased pressure between the two can lead to degenerative changes in the joints.

If you have problems such as degeneration of articular cartilage, it can cause pain in knee extension, and if the knee can be straightened, the quadriceps femoris composed of vastus medialis, vastus medialis, vastus lateralis and rectus femoris muscle should be the first thing to think of. The quadriceps muscle has the function of knee extension, and many of our patients with knee trauma are stuck in the last position of knee extension and cannot bend and stretch properly.

The different number of landing weights on the affected side, the longer immobilization time on the affected side, and the protection of the appliance make up for the activity of the quadriceps muscle, which eventually leads to muscle atrophy, and we all know that the function of the quadriceps muscle is to extend the knee!! Therefore, the lack of strength in the front of the thigh also makes the knee extend, which has a much greater effect than bowing, in addition, there is an ideal ** cycle for not straightening. In general, we ask patients to be able to fully straighten the knee within the postoperative week, as it is most difficult to straighten and recover later.

Although you try to press your legs hard every day, it is especially easy to recover.

There is a hole between the femurs of the knee joint, which is used to secrete synovial fluid and ensure the normal movement of the joint, but after the inflammatory reaction of the sac occurs, the sac will swell, seriously affecting the movement of the joint, and accompanied by pain, the hamstring muscle is composed of semimembranosus, hemiadductor and biceps femoris. Its function is to bend the knee, and its tendons are stuck behind the knee, so when these tendons are inflamed, the popliteal fossa will be painful, and the stretching of the muscles can be effectively avoided before exercise.

There are two main reasons for the pain when the knee is bent, patellofemoral osteoarthropathy and meniscus tear, which need to be examined and judged by the doctor.

In general, the knee is painful when bent and straightened, and it is more common in the early stage of osteoarthropathy, which is called patellar malacia, also known as patellar joint osteoarthropathy. It is mainly because the articular cartilage on the articular surface of the patella and trochlear in front of the knee joint is not smooth, wears and degenerates, and the pressure on the patellofemoral joint increases when it is bent, resulting in pain. When straightening, it does not hurt because the pressure on the patellar joint is very small and the pressure is not great.

Sometimes the knee bends and hurts, or even if it doesn't hurt, there may be other reasons, such as a tear of the meniscus in the joint, and when the right bend is just squeezed into the torn meniscus site, there is pain, and when it is straightened, the meniscus in front is intact and there is no tear, so it does not hurt, which is also a common cause of pain when the knee is bent, or even not painful. It may be that the patient is unable to squat or bend his legs, which has a greater impact on his life, so there are two main reasons for the pain when the knee is bent, one is osteoarthropathy of the patellofemoral joint, and the other is a torn meniscus. In this case, it is necessary to determine the cause through a doctor's examination.

If the meniscus is torn, a partial meniscectomy may be required by arthroscopic minimally invasive surgery, and if it is patellar joint femoral diameter disease, it should be treated according to the symptoms of patellofemoral osteoarthropathy**, nutritional cartilage**.

In the absence of trauma, it is likely to be synovitis, you can take some anti-inflammatory drugs and sprays, and if it does not get better for three days, it is best to go to the hospital.

Have you ever exercised vigorously or worked hard for a long time? If there is such a situation, it is not excluded that there is a meniscus injury, in this case, it is best to go to the local hospital to do a CT or MRI of the knee joint, if there is a meniscus injury, it depends on the specific situation, choose conservative** or surgery**.

It should be a strain, try to temporarily reduce bending and other things to restore health, or go to the hospital for a check-up is the most reliable.

Pain when the knee is bent and no pain when it is straightened is common for the following three reasons. Clause.

1. Patellofemoral arthritis, there is a patellar femoral articular surface between the patella and femur of the knee, when there is chronic injury or degeneration, there will be chronic inflammation of the joint, cartilage damage, and then there will be pain when the knee is bent, especially when going down the stairs. Clause.

Second, popliteal cysts, there is a popliteal fossa behind the knee, and when there is a larger cyst in the popliteal fossa, the pain will be more obvious when the knee is bent, but it is not painful when the knee is extended. Clause.

3. Meniscus injury, the knee has two meniscus, medial and lateral meniscus, when the posterior angle of the meniscus is torn, the pain will be very obvious when the knee is flexed, the patient can not squat or can not stand up after squatting, and there will be no obvious pain when straightening, the above is the common reason for the pain of knee bending and straightening.

Analysis: Hello, when the leg is straightened, the knee will hurt as soon as you exert force, and your case should consider knee synovitis. Synovitis occurs in various knee injuries or secondary to knee osteoarthritis, the former is more common in young adults, and most of them have a history of acute knee trauma, such as meniscus injury, synovial injury, cruciate ligament or collateral ligament injury, etc., and the latter is mostly elderly.

Suggestions: It is recommended to go to the hospital for a detailed examination. First of all, it should be bed rest, elevate the affected limb, compress and bandage with an elastic bandage, and prohibit weight-bearing.

Exercise quadriceps muscle contraction, straight leg raise can promote blood circulation, is conducive to joint fluid absorption. It can be applied externally**, and traditional Chinese medicine to invigorate blood circulation and eliminate blood stasis, relax tendons and activate the nerves, reduce inflammation and relieve pain. When there is a large amount of fluid and tension in the joint, a joint puncture can be performed to completely remove the fluid and blood, and sodium hyaluronate can be injected into the joint cavity.

You can go to the local hospital for X-ray examination to understand the specific situation, and carry out targeted ** after the diagnosis is clear.

Don't squat or kneel down too often to fetch things, and try not to sit on low stools and sleep on low beds to avoid increasing friction and weight bearing on the joints. At the same time, it is recommended to apply hot water to the knees after exercise, especially the strong thigh muscles, which can provide corresponding protection for the knee joint. The quadriceps muscles and tensor fascia dilators in the front of the thigh, the quadriceps muscles are strong, which can reduce the impact on the patella and meniscus during exercise, and many frontal knee pains are caused by this.

In the grass to (Looking for the solitary wind ointment).**Try. Good luck with a speedy recovery.

Analysis:

In this case, it should be considered or examined, and if there is redness and swelling in general, bacterial inflammation should be considered.

Guidance: Your condition should be considered to check for inflammation, appropriate antibiotics, and also to be usedXun blast ointmentExternal, oral ibuprofen sustained-release capsules.

The prose language of "Spring" is very beautiful, let's study how the author describes the spring breeze from multiple angles. (Students read and learn) Students:

The first sentence compares the spring breeze to a mother's hand, vividly and vividly writing the warm and soft characteristics of the spring breeze. Teacher: Have you ever been touched by your mother's hand?

Sheng: Touched. Division:

Tell us about when and how you felt. Sheng: The day before yesterday, my stomach was a little uncomfortable, so my mother gently rubbed my stomach with her hands, which was warm and comfortable.

Teacher: Some people compare the spring breeze to the hands of the devil, is that okay? Raw:

Resolutely) no! Because the spring breeze is the same as my mother's hands, they are warm and soft. Division:

It also uses the method of side description, through the description of the smell of earth, flowers, birds singing, and the sound of the shepherd boy's flute, to highlight the warmth, softness, and pleasantness of the spring breeze. Teacher: What is a side depiction?

Teacher: (The student is silent and asks after a while) Is the author taking a detour when describing the spring breeze but capitalizing the tune and flute? Raw:

blurted out) because this is the ** in the spring breeze, and the description is just right. Teacher: If it is a typhoon, will there be such a "tactful" ** in the wind?

Sheng: (suddenly) The author writes about the singing of birds and the sound of the shepherd boy's flute, in fact, they are all to highlight the warmth and pleasantness of the spring breeze, which is a side description! Division:

The language seems to be ever-changing, in fact, every word and sentence revolves around the warm, soft and pleasant characteristics of the spring breeze, although the kite flies high, but it is a line in hand, not vines and branches, this is the characteristics of the prose that are scattered and the spirit is not scattered! Of course, there are more than the above ways to taste language, but a good article does need to be savored in order to appreciate the rich thoughts and feelings it contains. The Curriculum Standards "appreciate the meaning and function of the linguistic environment" and "appreciate the expressive language in the work."

As a Chinese teacher, we should earnestly return to the original meaning of the language and lead the students to taste the beauty of the language, so as to inspire students to feel the beauty of humanity and the beauty of their mother tongue in the language, which not only improves their ability to interpret the text, but also makes the Chinese classroom full of strong Chinese flavor.

1. Massage: Massage helps to improve local blood circulation, anti-inflammatory and pain-relieving.

2. Traction: Traction can reduce the compression of bone spurs on local nerves and tissues and temporarily relieve pain.

Acupuncture: Acupuncture can invigorate blood through menstruation and have analgesic effects. It can eliminate local edema and inflammation, but acupuncture can only play an auxiliary role in bone hyperplasia.

5. Surgical smelting: Surgical smelting is not the first choice for bone hyperplasia. `

1. Purify the air.

Aloe vera, spider plant, tiger tail orchid, one-leaf orchid, and monstera are natural scavengers that can remove them from the air.

Hazardous substances. Studies have shown that tiger tail and spider plant can absorb more than 80% of harmful gases indoors, and the ability to absorb formaldehyde is super strong. Aloe vera is also a good absorber of formaldehyde, which can absorb 90% of the formaldehyde contained in 1 cubic meter of air.

Ivy, iron tree, chrysanthemum, kumquat, pomegranate, half lotus, moon flower, camellia, pomegranate, Milan, daisy, plum, marigold, etc. can effectively remove sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, nitrogen peroxide and other harmful substances.

Orchids, osmanthus, plum, taro, red-backed cinnamon, etc. are natural dust collectors, and their cilia can intercept and absorb floating particles and soot in the air.

2. Bactericidal bacteria.

The volatile oils produced by aromatic flowers such as rose, osmanthus, violet, jasmine, lemon, rose, caryophyllus, lily of the valley, crape myrtle and so on have a significant bactericidal effect.

Plants such as crape myrtle, jasmine, and lemon can kill native bacteria such as diphtheria and dysentery bacteria within 5 minutes. The fragrance of rose, caryophyllus, lily of the valley, violet, rose, osmanthus and other plants has a significant inhibitory effect on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus and staphylococcus.
