With the rapid development of medical technology, the recovery process of patients after joint replacement surgery is greatly accelerated; with the gradual increase in the number of patients undergoing joint replacement surgery, there are fewer and fewer beds in the operating hospitals for patients’ recovery; patients undergoing artificial joint replacement surgery are usually discharged from the hospital in about one week after the surgery. After being discharged from the hospital, patients will inevitably experience pain and discomfort during the recovery process, and some of them will be nervous and fearful that something may have gone wrong with the surgical site. What is the cause of the pain? How to deal with it? And then how to deal with it to ease it? First of all, although due to the great progress of surgical technology, arthroplasty has been close to the common people, but after all, it is a major surgery, the joints of the bones, ligaments and soft tissues have a certain degree of trauma, postoperative trauma requires a certain amount of time to return to normal, generally about six weeks to gradually approach the normal state. In layman’s terms, it takes a few days to recover from an accidental injury to a finger or toe in daily life, let alone undergoing a major surgery. Secondly, after undergoing artificial joint replacement, the previous state of the disease will be restored to a relatively normal state, such as the correction of O-shaped legs, the human body’s joints, limbs and the whole body need to be a process of re-adaptation. Proportionally speaking, in our daily life, we also need a process of adaptation when we change into new clothes. Once again, psychological worries and doubts after surgery can exacerbate the level of pain. Therefore, it is normal to experience some mild pain or discomfort in the replaced joint and the same side of the limb after surgery. As long as the pain is not too severe and tends to decrease gradually, there is no need to worry. Of course, patients need to note that if the pain appears suddenly, or worsens suddenly, or is accompanied by fever, localized redness and swelling and other discomforts, they should pay attention to it, and promptly contact the doctor at the time of consultation to clarify whether further treatment is needed. So, what are the ways to help gradually reduce pain and discomfort? First of all, functional exercise should follow the principle of gradual progress, excessive exercise will aggravate the pain; secondly, after each functional exercise, ice can be applied for about a quarter of an hour, which is conducive to reducing the reaction of local tissues; thirdly, psychological adjustment should be made constantly to reduce fear and worry; if necessary, some symptomatic drugs can be used under the guidance of the doctor; lastly, regular review should be carried out, and the doctor should give the appropriate guidance and help.
