What are you most afraid of after knee replacement?

The knee is an important part connecting the thigh and calf of the human body. If there is a problem with it, it will have a great impact on a person's normal upright walking. At the same time, because people pay little attention to the protection of their knee joints in their daily lives, problems with the knee joints are very likely to occur. In the past, people suffering from knee joint diseases could only endure the pain, but the development of modern medical technology has made knee replacement a possibility. So what should you pay attention to after knee replacement surgery?

Knee replacement surgery is one of the greatest innovations of the 20th century, helping patients with severe knee diseases to relieve pain and improve their quality of life. So how often does this replacement surgery need to be reviewed?

After knee replacement surgery, it is recommended to visit the hospital for a follow-up examination with the surgeon 6 weeks and 3 months later, and then visit the hospital once a year for an X-ray examination.

A follow-up examination is conducted 6 weeks after surgery to understand the healing of the wound, whether any suture ends have been dislodged, whether the joint stability and range of motion are normal, and to guide the patient's exercise methods.

Three months after surgery, we mainly understand whether the patient has a large amount of joint effusion and whether the range of motion meets the requirements. If some patients have poor range of motion, massage under anesthesia is recommended to achieve the range of motion of the knee joint required for normal life.

It is not easy for many patients to have annual check-ups, but just because the prosthesis is well positioned this year, there are no translucent lines around it, there is no bone absorption, and there is no cystic change in the bones, does not mean that there will be no cystic changes next year. Early detection, early prevention!

If any of the following situations occur, you should pay attention:

Fever, tooth extraction, bleeding wounds.

Infection is one of the most common reasons for revision of an artificial joint. Infections are divided into acute infections and chronic infections.

After an artificial joint prosthesis is installed, once bacteria reach the area around the prosthesis, they cannot be killed, causing an infection that cannot be controlled. Fever, dental operations, endoscopic examinations, and other minor surgical procedures can cause transient bacteremia. An important means of preventing delayed periprosthetic infection is the use of intravenous antibiotics. Taking necessary infection prevention measures can significantly increase the service life of artificial joint prostheses.

You need to see a doctor as soon as possible if you have any of the following:

1. Local redness, swelling, heat and pain in the joint, or small holes with fluid flowing out.

2. Feeling that joint movement is not as normal as before or is restricted.

3. Swelling of the entire limb accompanied by pain or joint deformity.

4. Joints become deformed and painful after trauma.

These conditions may mean revision surgery.
