How Long After Knee Replacement Can I Live a Normal Life? On what basis?

Knee replacement.

It takes 3 months for the knee to return to normal.

Knee replacement is the first osteoarthritis of the knee joint.

A commonly used method that can be given by replacement in the advanced stage of osteoarthritis**. It is necessary to get out of bed as early as possible after surgery, and actively carry out limb function exercises, especially the exercises of joint flexion and extension function, which plays a very important role in the recovery of joint function. In the early stage, it is necessary to focus on crutches or walker exercises, and after active exercise, you can gradually give up the assistive equipment for walking.

After 3 months of functional exercise, I was able to return to walking with normal knees and carry out my daily life and work.

If the patient's condition allows, it can be done 1-2 days postoperatively in the drain.

After pulling it out, you can get out of bed and move, walk, and gradually walk from the walker and crutches to partial and full weight bearing. Generally, after 2 to 3 months of knee joint functional exercise, the joints can return to basically normal and be able to walk normally. Only a small percentage of patients may have some symptoms of joint flexion and extension and limited mobility.

Therefore, after knee arthroplasty, it is recommended to get out of bed and exercise joint function early, so that the function of the joint can be restored as soon as possible and some complications can be prevented.

After knee replacement surgery, it is necessary to actively cooperate with the patient, which is more conducive to the rapid recovery of the patient after surgery, and the following points need to be done: in the early stage, it is necessary to carry out functional exercises diligently, and it is necessary to exercise the straightening and bending of the knee joint to restore the patient's normal knee joint mobility, so as to restore normal function. It is necessary to actively change the local knife edge to change the dressing, observe whether there is redness, swelling, heat and pain in the local area, and actively carry out symptomatic treatment to avoid the occurrence of infection.

You can return to normal life 2 to 3 months after surgery. After surgery, it is necessary to gradually increase the time of getting off the ground and walking every day, walk with the help of a walker for 6 weeks, and then remove the walker to walk on your own, and gradually increase the time and distance of walking.

For patients with obvious damage to the knee joint, degeneration caused by knee joint swelling, deformity, limited activity, it is necessary to type artificial joint replacement surgery, this kind of surgery is generally three days after the patient can use the walker to gradually go down to the ground to carry weight activities, and gradually begin to perform knee joint flexion and extension activities, generally with the help of the walker activity for three weeks can remove the walker to perform normal activities.

However, during this period, it is necessary to strengthen the flexion and extension exercise of the knee joint to restore the normal flexion and extension function of the knee joint, so the patient can return to normal life after four weeks of knee replacement surgery.

The range of motion of the knee joint requires that the range of motion of the knee joint should reach 90 degrees about a week after surgery, and the range of motion of the knee joint should reach more than 120 degrees one month after discharge, because within one month is the best cycle of the range of motion of the knee joint.

It's probably going to be two months away. As the saying goes, it takes 100 days to break your muscles and bones. Usually there is a quick recovery after two months of this surgery. Bones will also grow well.

Be sure to do 3 to 6 months of ** exercise, and after half a year you can be physically active. To prevent infection after surgery, it is necessary to exercise under the guidance of a doctor.

Patients must pay attention to diet, must pay attention to eat more nutritious food, and it should be noted that after the operation, they must pay attention to rest, do not do some strenuous exercise, under normal circumstances, it can return to normal in about a year.

It should be noted that you should not run after surgery, you should not walk for too long, you should pay more attention, and it will take at least one year for the elderly and at least half a year for the young to return to normal.

Some patients recover very quickly and can resume normal walking within 1 to 2 months after surgery. Some patients recover slowly after surgery, and if there are corresponding complications, the time to return to normal walking is relatively long, and in some cases, it takes more than 3 months to be able to resume normal walking.

It will take about a year to return to normal life, because after the replacement of the knee joint, it needs to go through a long period of recovery and running-in, so as to reduce the pain when walking, and to ensure the normal walking posture and walking speed.

After knee replacement, it takes about two months to return to normal life, because the course of knee replacement is relatively long.

There are several of the most common sequelae of knee replacement:

The first is the wear and tear of the joints. In almost all patients, the prosthesis will wear out after a certain number of years, which may be 10, 20 or 30 years, especially the knee joint.

Second, the joints are loosened, the bones are destroyed, and they are already unstable.

Thirdly, there is pain after knee surgery, and the patient wants to squat down, but cannot squat completely. It may be painful when you squat, but it may not be as bad when you walk.

Fourth, if you can't achieve a satisfactory effect, the satisfactory effect is that you can squat completely. For example, a patient cannot go to the toilet by himself and cannot squat completely, especially for female patients.

There are also very fat patients who have problems with squatting in the first place, so they hope to be able to squat after an operation. Although this movement is difficult, it can solve the pain, and it is still more difficult to squat completely. The sequelae after knee arthroscopic surgery generally have muscle atrophy, and functional exercises are required for a period of time after surgery, which can be recovered slowly.

The second is infection, pay attention to wound care after surgery, regular disinfection, keep the ** dry, and need to apply appropriate antibiotics. The third is blood clots, which are bedridden for a long time, which slows down the blood flow rate and makes it easy to form blood clots.

Usually, patients do not need to stay in bed for a long time, and actively perform joint function exercises. Appropriate oral anticoagulants are also needed to avoid excessive blood thickening. At the same time, it is necessary to pay attention to a light diet, mainly active joint function exercises, so as to prevent muscle atrophy, joint adhesion and thrombosis.

No matter how old you are, a defective knee prevents you from participating in the activities you enjoy. Pain and stiffness can even limit your life. Knee problems get worse over time.

Here are some reasons why your knee can be painful.

1.Joint injuries that do not heal well.

2.Chronic illness.

3.Senile injuries.

With a knee replacement, you can spend the rest of your life without having to suffer from knee pain. Total knee replacement surgery almost always relieves your joint pain. Your injured knee joint is replaced by an artificial joint.

Surgery doesn't make you young again, however, the vast majority of patients who have a total knee replacement will get all of the benefits:

1.Joint pain is completely absent or significantly reduced.

3.The quality of life is improved, you are able to complete your daily life with ease and participate in some exercise.

4.For long-term activity, the vast majority of total knee replacements with imported prostheses can last for many years.

The timing of surgery is determined by a number of factors:

1.Anesthesia: Some patients may have difficulty in administering their own anesthesia, or the anesthesiologist's level is limited;

2.Surgery: the patient's condition is complex, or the surgeon's skills are limited;

If the anesthesia goes well, it takes about 1 hour from the incision to the suture of one knee resurfacing hand.

Depending on the condition of the surgery, it will take about 2 hours. I don't know, yes, yes.

Can you tell us what your problem is, do you need surgery? Do you want to be cured without surgery?

Good surgical results, short hospital stay, can allow patients to return to normal life soon after surgery. Patients who have not yet decided on surgery are often worried about being bedridden for a long time after surgery, unable to take care of themselves, and needing to be accompanied by others. Then do artificial knees.

Joint replacement surgery.

No problem for 3-5 days.

One. The following factors help to get out of bed early after surgery.

1. The quality of the operation is high, and there is no problem with the stability of the artificial joint prosthesis;

2. After the operation, the general condition is stable, able to eat normally, and the physical strength is good;

3. The drainage tube was successfully removed within 48 hours after the operation;

4. Able to tolerate incision discomfort (there will be slight pain, local swelling), or use self-controlled analgesic pumps, or oral non-steroidal analgesic drugs are basically painless;

5. Able to use walkers or crutches (short-term);

6. Good attitude and confidence in close cooperation.

Two. The benefits of waking up early for activity.

1. Get out of bed one day earlier and gain self-confidence one day earlier;

2. Get out of bed one day earlier, familiarize yourself with and use new joints one day earlier;

3. Get out of bed one day early, avoid the complications of bed one day earlier, increase physical strength, improve appetite and sleep.

Three. Precautions after getting out of bed.

1. You must be accompanied by medical staff for the first time after surgery, and they will teach you some methods and precautions. More importantly, you can judge whether the time to get out of bed is appropriate and how much activity is better.

2. There will definitely be mild discomfort during the exercise, such as lack of strength, swelling and pain in the joints, etc., especially at night, the lower limbs feel messy, don't worry. The discomfort will gradually lessen over time until it disappears;

3. Pay attention to whether there is bleeding at the incision site, and whether there is abnormal edema in the lower leg and foot;

4. In addition to general walking, more attention should be paid to joint range of motion exercise and muscle training around the joints;

5. Closely cooperate with the doctor's plan, actively flex the knee joint more than 90 degrees before discharge (10 days after surgery), and be able to actively and completely straighten the calf. After you are discharged from the hospital, be sure to follow the exercise habit during your hospital stay.

6. 3 months after the operation is the plateau period, under normal circumstances, the patient will fully recover and obtain a new joint that is stable and has satisfactory range of motion.

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.
