Is it difficult to have a knee replacement surgery?

Knee replacement surgery is a bit more difficult and risky, but it is no problem for professional arthropists. Surgery is risky, because any surgery is risky, artificial joint surgery is the use of metal, ceramics and other materials according to the human body joint shape caused by the prosthesis, through surgery transplanted in the human body, instead of the patient's joint activities to achieve the joint can walk state. After knee replacement surgery, you can walk easily, which is what we aim for.

Generally, when we walk, we have lesions, trauma or injuries to our joints, and when we have pain when we walk, and when the symptoms are severe, the doctor recommends that we have knee replacement surgery. Because of these surgeries, because these diseases have seriously affected our daily life, even if we lie down to sleep, it will be painful, and we will definitely have to change the joint. After we have knee replacement surgery, we must pay attention to our sleeping position, if we sleep on our side, we should put a pillow in the middle of the leg, so that it is convenient to keep the knee joint straight, if we lie flat, we must put a pillow under the knee.

When discharged, it is necessary to keep the surgical mouth clean and not contaminated, and if it is contaminated, it is necessary to go to the hospital to change the dressing in time, otherwise it will lead to serious consequences. It is normal for the surgical incorpoline to feel numb and nervous, so there is no need to worry about it, and it will decrease over time. <>

When we have surgery, do not always follow a movement to keep the same, which will lead to knee injury, can not sit directly on the chair cross-legged, let alone kneel on the ground or sofa, can not go up the stairs too much, to use the elevator is more convenient, can not take heavy things, this will cause joint injury. In daily life, when walking, you should take small steps, not big steps, and if you want to turn around, you should first turn your feet and turn your body. We should also pay attention to our body after the operation, our diet should be lighter, not spicy, not alcoholic, and not to eat some hairy foods, because these foods are likely to cause our illness to be more serious.

Total knee replacement.

The purpose of total knee arthroplasty is to relieve knee pain, correct knee deformity, and improve knee function;

Indications: knee osteoarthritis, knee rheumatoid arthritis, knee post-traumatic arthritis;

Contraindications: knee joint infection (absolute contraindication); neuropathic joints (relative contraindications); unsatisfactory coverage of surrounding soft tissues; Significant ligamentous insufficiency or extensor tendon device insufficiency.

Complications: Recent: surgical injury - nerves, blood vessels; arterial embolism, fat embolism, bone cement allergy, venous thrombosis; senile complications;

Medium-term: swelling, pain, rejection, joint effusion, muscle atrophy;

Late stage: The joint is loose, worn out, and needs to be revised.

Knee arthroplasty is the most advanced surgery in orthopedics, so is it very risky?

In daily life, if our body has some adverse symptoms, we will choose to go to the hospital to let a professional doctor see us and make relevant **, but some people will need to do some surgery because of the condition, and some people regret it after the operation, so what should I do if I regret it after joint replacement surgery? Let's take a look at it with the questions.

The advantage of joint replacement surgery is to solve the problem of joint pain, and it is better to restore joint function, and through joint replacement surgery, it can be better to improve and eliminate the symptoms of dysfunction, but some people say that they regret it after joint replacement surgery, because this part of the patient will have joint stiffness and muscle atrophy after surgery. Joint stiffness and muscle atrophy are difficult to recover from, and if they do not recover, they may affect their daily activities.

Finally, it is recommended that people should follow the advice and guidance of professional doctors after surgery, including diet, as well as exercise after surgery, and actively cooperate with doctors, so that the body will not have some adverse reactions after surgery.

When the human knee joint has lesions and deformities, it is very painful and seriously affects daily life behavior, and the people who do not work or have unsatisfactory results can undergo artificial knee replacement surgery. Knee replacement surgery is a procedure in which a damaged joint is removed and an artificial implant is fitted in. Now the surgical technology has been gradually improved, and the condition of many people with severe knee joint lesions has been solved.

1. What is artificial knee replacementWhen the knee joint of our body is deformed or worn out, the knee with osteoarthritis seriously affects people's daily life, and there is still no improvement after many times, then we can replace the knee joint. First of all, the articular cartilage that has been worn or diseased is removed, and the prepared replacement joint prosthesis is installed on the bone surface, according to the size of the patient's bone to select the matching replacement joint model, at the same time select the appropriate thickness of the spacer, and test the mobile flexion and extension function of the knee joint during the operation, punch holes in the bone, install the appropriate replacement prosthesis and spacer, and the operation is completed.

2. Under what circumstances do you need artificial knee replacement, but people with serious joint diseases such as osteoarthritis, rheumatoid arthritis, traumatic arthritis, and lupus erythematosus arthritis can undergo knee replacement. However, not all patients with these diseases must undergo replacement, and they must meet the following criteria: patients with severe knee deformity and poor mobility; Patients who have been producing moderate or severe pain for a long time; Patients whose condition is still not improved after a long period of conservative ** and whose medication alone does not work.

All of these patients can undergo knee replacement.

When the function of the knee has been destroyed, which seriously affects people's normal life, artificial knee replacement surgery can be performed. With the improvement of surgical technology, the materials and workmanship of the implant are gradually improving, and the service life of the replacement implant is much longer than before. This surgery has brought an easy and enjoyable life to many patients who have had their knee replaced.

Hear what the orthopedic surgeon has to say!

1.Knee fusion surgery takes a long time for bone to heal, and X-rays are needed to determine the healing status.

2.Considering that you are relatively young, it is best to do total knee resurfacing surgery, so the surgical technical requirements are relatively large, but if you do hinged knee joints, it is simple, but the long-term effect is not good. The feasibility of surface replacement depends on the condition of the bone defect and the condition of the surrounding ligaments.

It's best to go to a better hospital, because some hospitals will choose to hinge directly in order to reduce the difficulty and risk).

3.There is no unified standard for the cost of total knee surface replacement, and it depends on the level of the hospital (the charging standards of different levels of hospitals are different, the higher the grade, the higher the charge, but the equipment, conditions, and technology will be better). Domestic prostheses are about 2-3W, while the total cost of imported prostheses is 3-6W (different types of prostheses** are different, and the choice of prosthesis should be decided according to the patient's condition).

If the landlord is willing, he can send the x-film to this mailbox, and then inform the specific possibility after reading the film.

Fusion ??? So miserable... About 6-90,000. Several major hospitals in Beijing are similar... Jishuitan, the Third Hospital, the People's Hospital, the Beijing Hospital of the Ministry of Health... You have a difficult operation...

After knee arthroplasty, some patients do not pay attention to the protection of the new joint and think that they can rest easy after changing the joint, while some patients pay too much attention to the new joint and are careful about what they do. So, after artificial knee surgery, what kind of exercise and diet is "moderate", please refer to the following suggestions:

1. It is not recommended to do squatting, wearing shoes and socks within six weeks after surgery, and after six weeks, wearing shoes, socks, walking, jogging, swimming and other behaviors can be carried out. If some patients are not comfortable and think that six weeks after surgery is too early, they can also postpone it until three months later;

2. After artificial knee arthroplasty, it is not completely impossible to "stilt the legs" and cross the legs. However, these behaviors can not be done until three months after surgery and the patient has recovered well. If you do "stilt legs" and cross-legged movements within six weeks after surgery, it is likely to lead to hip dislocation, which is very dangerous;

3. Patients should not sit for a long time after surgery, because sitting for a long time is a test for the hip joint and lumbar spine. In general, this "long time" means more than 30-40 minutes. That is, it is recommended that the patient sit for 30 to 40 minutes and stand and walk for a while;

4. Postoperative patients need to pay attention to "good up and bad down" when going up and down the stairs, that is, the leg on the healthy side goes up first when going upstairs, and the leg on one side goes down first when going downstairs. In addition, for three months after surgery, patients should try to hold on to handrails when going up and down stairs. Because on the one hand, the joint may not be very stable after hip replacement; On the other hand, patients may fall after surgery due to muscle weakness.

But after three months, if the patient has recovered better through the side leg raise, there is no need to be so careful;

5. If the femoral head necrosis is caused by alcohol consumption and knee replacement is required, it is still recommended to quit drinking or reduce alcohol consumption even if the new joint is replaced. Because continued drinking after surgery may lead to necrosis of the femoral head on the contralateral side (good side), and may also cause damage to the liver and kidneys;

6. There are not many precautions in diet after artificial knee replacement, and there is no need to avoid eating because of it.

This kind of surgery is a failure, the joint can not bend normally, this is because the operation artificially injured the ligament inside, and the ligament injury will naturally affect the normal bending and straightening function of the joint. Ligaments belong to soft tissues, it is difficult to repair itself after injury, it is difficult to achieve healing by artificial forced bending alone, in bone trauma, ligaments, cartilage, meniscus and other soft tissue injuries are more difficult to treat than fractures, whether it is to recuperate at home or exercise is difficult to heal on its own, and a long delay will only increase the difficulty of the future.

If you want the joints to return to normal, it is recommended to immediately use traditional Chinese medicine**, because only Chinese medicine can repair damaged soft tissues, and the ligament damage within two months in the early stage can be treated with traditional Chinese medicine**, which can be basically ** in about 40 days, and the joint bending will naturally return to normal (no painful exercise).

Before the first time, avoid forcibly exercising the flexed joints, so as not to aggravate the damage of the ligaments.

There are surface and twisted knee arthroplasty, many ligaments are cut out during surgery, and there are various types of prostheses, such as preserved posterior cruciate ligament and non-retained posterior cruciate ligament.

Functional exercise after knee arthroplasty is very important and painful, try to move to 90 degrees within two weeks after surgery, if it is difficult to exercise on your own, you can do CPM machine training, in short, it is best to have a special ** teacher guidance.

What should I do if my knee replacement fails?

Qu Tiebing, Department of Orthopedics, Beijing Chaoyang Hospital:

All patients who need a knee replacement will have the same question: What is the material of the knee joint I am receiving? How long can it last?

Do you need to "save money"? This problem starts with the material of the artificial knee joint, which is made of high-tech cobalt-chromium-molybdenum alloy and ultra-high molecular weight polyethylene liner. There is an experiment on the analysis of the life of artificial prostheses, and the bioengineering laboratory of Harvard University in the United States has done a study

They simulated artificial joints mounted on corpses in a biological solution that simulated the movement of the human body under a gravity load of 60 kilograms, and the polyethylene liner wore out by just millimeters in the equivalent of 10 years of movement. This means that it takes 100 years to wear out 5 mm and damage the liner! Of course, laboratory tests are not equal to real human movements, and human joint movements are multi-faceted and diverse; Moreover, no doctor or patient can be as precise as a tester.

When these objective influencing factors are removed, the effective survival of the prosthesis in the real human body is 25-30% of the laboratory results, and even so, the effective life of the prosthesis is 25-30 years! Therefore, using artificial joints is like driving a car, which can be used for many years, or even more, if nothing happens under normal circumstances.

No problem for twenty or thirty years. If you overload your car, you may end its useful life and your car will be scrapped. We followed up on the domestic artificial joints that were replaced more than ten years ago, and more than 90% of the patients still continue to use them.

Therefore, artificial joints made with today's high-tech concepts and materials should theoretically have a service life of at least 20 years if they are properly installed.

However, patients who are young, overweight, active and osteoporosis are prone to premature wear and tear of artificial joints. Among them, osteoporosis is:

Artificial joint replacement.

The greatest enemy. I often tell my patients that joint replacement is like making a door, and that doctors are good craftsmen who can make a good door. The prosthesis is like an imported high-grade hinge and has a long lifespan, but if the wood used to make the door decays after a few years, the door will be deformed, and the hinge will fall off before it reaches its useful life.

Therefore, patients who have undergone artificial joint replacement must prevent osteoporosis and exercise and maintain it under the continuous guidance of doctors. The lifelong follow-up system implemented by patients who receive artificial knee replacement in the department I preside over is to re-examine every year, check the condition of the prosthesis, check the bone density, and provide targeted guidance and ** according to the patient's condition.
