What knowledge should you understand before Joint replacement surgery? 

 

What is knee resurfacing?

Knee joint surface replacement is the replacement of cartilage on the surface of the knee joint. When the surface of our knee joint is worn away, we need to replace the 2mm cartilage like an implant surgery and replace it with a titanium alloy.

 

 

What does the bone cement for joint replacement look like?

Bone cement is polymethyl methacrylate, which is composed of a pack of powder and liquid. Mixing the two will gradually become solid and become bone cement that acts on the human body. The knee joint prosthesis is combined with bone cement through the back, so that it will be stronger.

 

 

How to choose artificial joint for knee replacement?

1. According to the patient’s condition, if it is a more severe varus knee, severe varus knee, or an overweight patient, the joints he applies should use imported joints;

2. According to the economic situation of each patient’s family;

3. Some particularly thin patients need special prostheses;

4. Patients with hyperallergic physique need to use anti-allergic material prosthesis.

 

 

 

How many years can artificial joints be used?

Artificial joints are basically made of titanium alloy and good ceramics. Usually in vitro experiments show that they are wear-resistant for 50 years. After entering the body, clinical experiments also show that they can reach 20-30 years.

In actual clinical work, there are also patients who are renovated or can continue to use them after 30 years.

Therefore, in general, artificial joint replacement is a mature operation with a relatively long service life.

 

 

How to do rehabilitation training on the first day after knee replacement?

Knee flexion and continuous back extension of the instep can effectively promote swelling and prevent venous thrombosis.

 

 

What happens to the mobility function after knee replacement surgery?

After knee arthroplasty, the patient’s joint movement is basically normal and can bend to more than 120 degrees.

 

 

Can the knee replacement be the same as before?

Theoretically speaking, after knee replacement surgery, most of us can return to the same life as normal people, but we must pay attention to scientific and reasonable postoperative exercises after the operation, and generally return to normal within three months.

 

 

How long can I walk after knee replacement?

At present, because of the intervention of rapid rehabilitation, the knee joint can walk on the second day after surgery. However, it may take one and a half months to three months to return to normal. It depends on each person’s recovery.

 

 

Do I need to lose weight after artificial joint replacement?

The life span of artificial joints cannot be excessive, so weight does have an effect on it. Under normal circumstances, obese patients are more likely to suffer from osteoarthritis than ordinary people. Some obese patients are overweight and wear their knee joints before they need artificial joint replacement. After the knee replacement surgery, the amount of activity may increase, and the weight will gradually decrease. In general, being able to control weight can naturally extend their lifespan.

 

 

 

How long can I bear weight after artificial joint replacement?

Usually, as long as the surgical technique is passed, the patient can get out of bed and move part of the weight the next day after the operation, and proper knee exercises can restore the muscle strength of the knee joint as soon as possible.

 

 

Do I need calcium supplementation after replacing artificial joints?

The need for calcium supplementation depends on each person’s osteoporosis. Not every patient after artificial replacement needs calcium supplementation.

Most of the patients who need calcium supplementation for artificial joints are caused by osteoporosis, so calcium supplementation should be based on the condition of the disease.

 

Why is it necessary to prevent venous thrombosis of the lower limbs after knee replacement?

Venous thrombosis of the lower limbs is a serious complication of knee replacement. It can be life-threatening, so we must actively prevent it.

Such as the use of elastic stockings, early postoperative activities, and commonly used anticoagulant drugs to effectively prevent venous thrombosis.

Generally speaking, the incidence of venous thrombosis after knee replacement is very low, and it usually does not occur if it is actively prevented.
