For arthritis there is a common misunderstanding that arthritis is a disease of old age, joint replacement has a certain service life, artificial joint replacement surgery is only applicable to elderly patients (greater than 65 years of age), so for young people (less than 65 years of age), with end-stage arthritis, is it possible to do joint replacement surgery? Question 1: How long does an artificial joint last? Many patients believe that an artificial joint will only last a maximum of 10 years after a hip or knee replacement, and are concerned that they will need another surgery to replace the artificial joint. This not only means enduring pain again, but also having to take the risk of complications. Answer: Artificial joints generally last 20 years or more. It is true that at one time artificial joints only lasted about 10 years, but technological and medical advances have extended the life of artificial joints. Nowadays, the life expectancy of an artificial knee or hip joint is generally 20 years or more, and most people are able to use the same artificial joint for the rest of their lives. Therefore, patients do not have to wait until they are 65 years old to receive a joint replacement. Question 2: Is joint replacement a last resort? Is it best not to go under the knife until it is absolutely necessary? After all, surgery carries risks, and if it fails or complications occur, it could be worse than before. Answer: It doesn’t have to be a last resort . Conservative treatment, including oral and topical medications and physical therapy is indeed the treatment of choice for people with arthritis. If the condition has progressed to the point where it is affecting your normal life and limiting your mobility, then ask your doctor if you can undergo a joint replacement without having to live with the pain all the time. It is important to realize that being in pain for a long period of time is not good for your health, and coupled with limited mobility, you are likely to gain weight, your quality of life will plummet, and your risk of cardiovascular disease will rise. Many patients who have undergone joint replacement regretfully think “Why didn’t I have the surgery sooner?” No matter how old you are, if the pain and mobility are unmanageable and disruptive to your life, surgery can be considered, and your surgeon will make a judgment call and give you advice based on your individual situation. Question 3: Long recovery time after surgery? Once the joint is replaced, does it take a long time to recover? If you need to stay in bed for a year and a half or cannot move independently, your life and work will be affected. Answer: Life will not be affected for a long time. After undergoing knee or hip replacement, some patients only need to be hospitalized for 1 week, while others need to be hospitalized for 2 months. Overall, recovery from surgery is staged and is not spent in bed from start to finish. Some patients recover in 4-6 weeks (being able to move their joints and walk in a natural way), while others take up to 6 months, but patients are usually able to bathe or drive on their own in about 4 weeks. Factors such as the patient’s attitude towards rehabilitation, motivation to participate in postoperative physical therapy, and the presence of complications will affect the recovery time, so it is not possible to generalize. Question 4: Can I still do sports after surgery? After the artificial joint is installed, is it like having a prosthetic limb installed, so I will never be able to play sports in the future? Answer: Of course you can play sports . In fact, most doctors expect patients to maintain a certain level of activity after their joint replacement. Walking, swimming, and bicycling are some of the less physically demanding forms of exercise that are appropriate for patients who have had joint replacements. Some patients are even able to engage in extreme sports such as hiking and triathlons after recovery, although this is not the norm. If you are concerned about the intensity and amount of exercise, you can ask your own doctor before exercising. If you are in the recovery phase, then it is best to exercise under the supervision of a physiotherapist to keep track of exercise time, rest intervals, and know exactly under what circumstances you should stop exercising immediately. Question 5: Will my legs grow shorter after surgery? There are many patients who are concerned that after receiving a hip replacement they will have one long leg and one short leg, which will appear very obvious when they walk. Answer: What are the criteria for short and long legs? X-ray images, posture when walking and the length observed by the naked eye are all criteria. An experienced surgeon will take into account the effect of posture on leg length, the curve of the patient’s crural spine, and the position of the implant to adjust his or her surgery so as to avoid short and long legs. In addition to relying on experience to make judgments, the surgeon’s use of high-tech tools such as real-time X-ray imaging during surgery can also help them better select the location of the joint implant. After surgery, patients may be somewhat uncomfortable with their new hip joint and feel strange when walking or standing. This is actually because for several years prior, they may have been unable to straighten their backs due to pain or joint deformity. This is common and not something to worry about as a result of a failed surgery.
