What is knee replacement all about? Nowadays, many elderly people suffer from knee pain and struggle to walk, so experts recommend that you get an artificial knee replacement to ensure that no accidents happen in your daily life. So what is knee replacement all about? Let’s find out. Some years ago, when people heard about joint replacement, it was hard to accept it from the heart, and they always thought, “My knee joint is not working anymore, but it is my own. Although, the original knee joint is your own, but it has reached the end of its life, not only lost its proper function, and bring you is discomfort is pain, just like a bad tooth, let you pain let you can not eat, so why not pull out why not replace a false tooth? In other words, why not replace a broken knee joint with a new one? In the United States, the entire population is approximately 230 million, but 400,000 total knee replacements are performed each year, which means that as the economic conditions of the entire population improve, and as the awareness of the population changes, total knee replacement surgery will become as common as replacing dentures. Because the entire operation time (skin incision to suturing) is about 60 minutes, the bleeding during the whole treatment is about 140-200 ml, and most of the patients do not need blood transfusion, which means that the “no blood transfusion technique” minimizes the trauma to the patient. Likewise, the “no-pain technique” is a great advancement in recent years in artificial knee replacement surgery, and is one of the highest levels of surgery we pursue. Perhaps some patients refuse the surgery because they are afraid of pain. Indeed, a number of years ago, knee replacement surgery was a rather painful operation, but in recent years, with our continuous exploration and improvement, we have basically eliminated the painful feeling of this surgery to some extent. After the surgery and even before discharge, more than 90% of the patients told us that “I have not had any pain at all since the surgery” or “a little bit of soreness and swelling”, although it is not yet possible to be “comfortable” as some patients describe. Although it is not yet possible to be “comfortable” as some patients describe, at least the pain is completely gone as it was before. From the recovery point of view, immediately after surgery, that is, after waking up from anesthesia, the patient can carry out leg lifting exercises, and on the first day after surgery, the patient can flex to more than 90° and can walk on the ground, and on the first day after surgery, the patient can stay in the hospital for about 3 to 5 days after surgery if it is normal, and most of the patients can return to the normal state in about 3 months after carrying out regular rehabilitation exercises under the guidance of doctors. return to normal. Knee replacement surgery is not as serious as people think, as you can see from the above description. The surgery is not as serious as one might think, and the patient’s knee will be as flexible as it was before. For younger patients, unicondylar replacement is an option. It is also an ideal treatment method.
