People don’t get old before their joints do. What are the conditions that require artificial joint replacement? Will you be able to run and jump freely after a joint replacement? Let’s hear from Dr. Li Hu, Deputy Chief Physician of the Department of Bone and Joint Surgery at Peking University People’s Hospital: What is artificial joint replacement? What is an artificial joint? People don’t know much about artificial joints, and often think that the surgery will involve removing the joint and putting in a stainless steel joint, which will make the limb look like a robot. In fact, artificial joint replacement should be accurately called surface replacement surgery, which only removes the worn and damaged joint surface and fixes a suitable artificial joint sleeve on the part that needs to be filled, just like filling a tooth, to restore the normal smooth joint surface and achieve the purpose of relieving pain and restoring function. Currently, total hip and total knee joint replacements are the most common. When to consider artificial joint replacement? 1.The joint has been in pain for a long time and it starts to prevent you from walking normally. 2.The walking distance is gradually shortened. 3.The movement of the joint is limited and the pain can be produced or aggravated by going up and down stairs or standing up from a chair. 4.The joint is severely stiff or deformed and the movement is limited. 5.The joint is in constant pain and there is little improvement in the pain after physical therapy or pain medication. How long can the artificial joint be used? At present, the international post-operative use of the excellent rate is usually twenty years. 1, to avoid trauma to the artificial joint 2, pay attention to some inflammatory diseases may lead to shorten the service life. 3, to moderately increase the muscle training around the joint. Artificial joint price? Imported hip and knee joints 50,000-60,000 (unilateral), domestic knee and hip joints 30,000-40,000 (unilateral). Medical insurance currently reimburses a portion of the cost, which is about$9,000. How long does it take to grow strong after surgery? Many people can get out of bed and walk two or three days after surgery, but it usually takes about 6 weeks to grow strong. If you want to do proper exercise, it is recommended that you do so 3 months or 6 months after surgery. Two post-operative muscle training methods – actually suitable for all healthy people If you don’t want your joints to fail before they get old, these two movements need to be done early! Knee muscle training – calf lift exercise: sit firmly and lift your leg, toe towards your body with force, insist for ten seconds, then put it down and rest for ten seconds, practice 20 sets, once in the morning and once in the afternoon, the muscle tissue strength is strong and can better protect the stability and durability of the joint. Hip muscle training – side leg lift exercise: lying on the side of the bed, thigh side lift, adhere to ten seconds, and then put down to rest for ten seconds, practice 20 groups, once in the morning, once in the afternoon, after 6 weeks there will be obvious results. Expert Li Hu special reminder one: avoid bravery: a thousand words of advice, the elderly must prevent falls. When people are old, many actions they want to do, but their bodies can no longer do it, and try to do some actions that lead to falls, such as doing “golden chicken independence”, which is often easy to cause hip fractures. Therefore, when people are old, they must act according to their ability and remember to avoid falling. Two: early medical consultation: usually the legs and feet are not good, especially the knee joint problems of the elderly, must be early medical consultation, the doctor will guide you through drugs or exercise methods to reduce pain, but also so that the disease does not develop too fast, also will not be easy to fall. Third: the replacement: after a fall and fracture, if you need to do artificial joint replacement, do not hesitate and delay, because the elderly pre-operative window is very short, a period of bed rest is easy to cause pneumonia, cardiovascular and cerebrovascular disease, bed sores and other complications, missed the timing of surgery, but also increased the risk of death. Fourth: care for the joints: whether artificial, or their own joints, the use of the process should be kept in mind: protection, care, moderate. Like squatting, climbing and other movements that are more harmful to the knee, it is recommended to avoid as much as possible. Orthopaedic surgeons most advocate non-weight-bearing exercises – cycling, swimming ……
