With the widespread use of artificial joint replacement in clinical practice, many patients wish to undergo this type of surgery. So before the surgery, questions about artificial joint replacement become a topic of great concern to patients and their families. First, will the artificial joint be worn out? Artificial joint replacement surgery is to remove the worn and damaged joint surface, and then implant an artificial joint, so that it can restore the normal smooth joint surface, to achieve the purpose of relieving pain. Artificial joints are made of wear-resistant alloy and polyethylene, and are molded according to the structure, shape, and function of human joints. In order to make the joint bones close together and prevent loosening in the future, most of the joints use bone cement to make the bones and prosthesis close together. Which joints can be replaced? Currently, artificial joint replacement has been used to treat shoulder, elbow, wrist, interphalangeal joints, hip, knee and ankle joints, but total artificial hip and knee replacement is the most common. Globally, more than one million patients undergo this type of surgery every year. What is the need for artificial joints? If your hip or knee joints have been hurting for a long time; the pain starts to prevent you from walking normally, or even limp; the walking distance is gradually shortened, and the joint activities are limited; sometimes going up and down the stairs or getting up from the chair can produce or aggravate the pain; the joints are stiff or deformed, and the activities are limited; the joints are in constant pain, and the pain is almost not improved after physical therapy and pain medication; there are X-ray changes of joint destruction. X-ray changes of joint destruction. When these symptoms gradually affect your life and work, do not wait, as soon as possible to the orthopedic surgeon’s office, perhaps you need to receive artificial hip, knee replacement surgery. What are the expected results after artificial joint replacement? Hip and knee joints are important joints for walking, running, jumping, squatting and other functions, and they also bear the weight of your body. Once the hip and knee joints become diseased, the cartilage of the joints will be destroyed, and the smooth surface of the joints will become rough or even defective, which will also lead to deformation of the head of the femur and the joint surface. As a result, you will experience pain, difficulty walking, restricted movement, limping, and sometimes difficulty in performing even simple movements. When the disease has progressed to such a severe level that the joint has been destroyed, surgery is required to replace the original destroyed joint with an artificial joint. The biggest benefit of artificial joint surgery is that it can eliminate joint pain after surgery, greatly improve the function of diseased joints, and improve the quality of life of patients. How long can artificial joints be used? There is no certain answer to the duration of use of the joint. Like driving a car, if it is used normally without accidents, the car can be driven for a long time; if you don’t take care of your car, overloading it every day and walking on the rugged mountain roads, I believe that your car will end up in the end of its life soon. Generally speaking, if used normally, 95% of artificial joints should have a service life of more than 10 years, and 90% of patients can use them for more than 20 years, that is to say, these joints are still 90-95% good after 10-20 years, and they can still satisfy the needs of your daily life. The younger the patient, the more active or heavier the patient is, the more likely the artificial joint will wear out and loosen, so unless there are special circumstances, physicians will try to wait until the patient is older to replace the artificial joint. At the same time, patients should also maintain an ideal body weight and avoid strenuous exercise to minimize wear and tear of the artificial joint and the chance of reconversion in the future. Can people with high blood pressure, heart disease and diabetes have hip or knee replacement? Generally speaking, patients with high blood pressure, heart disease and diabetes should be more cautious about having hip or knee replacement than those without these problems. If a patient with high blood pressure can keep it within normal limits with medication and has no other complications caused by high blood pressure, he or she can have an artificial hip or knee replacement. If there is heart disease but the heart function is good, without serious arrhythmia and angina, etc., most of them can have hip and knee replacement surgery. Diabetic patients have a higher risk of postoperative infection, so they should take long-term medication to keep their blood sugar in normal range after surgery. Patients suffering from the above diseases need to undergo a comprehensive pre-operative examination and preparation, and then make a comprehensive assessment before considering surgery on diseased joints.
