After artificial hip replacement, many patients report that the wound keeps hurting even though the doctor said the surgery was successful. So, is this pain caused by the surgery? What should be done? In fact, a large incision is needed to remove the “bad bone” and put in a new joint. It is impossible to have such a large operation without any pain in the wound after the operation, but this pain should be treated differently in each case. Li Hu of the Department of Bone and Joint Surgery, Peking University People’s Hospital, Beijing, China does not need to be overly nervous if the wound is painful within six weeks after surgery. Because this pain is the tissue damage caused by the surgery, causing an inflammatory response, only some non-steroidal anti-inflammatory and analgesic drugs, such as fenbendazole and fotarine, are needed. For patients with gastric disorders, drugs such as ciloxib and meloxicam, which are less irritating to the stomach, and indomethacin suppositories, which are basically non-irritating to the gastrointestinal tract, can be considered. In addition, some blood-activating drugs can also be used appropriately. In conclusion, most pains within six weeks are aseptic inflammatory pains, and medication will solve the problem. However, if the patient thinks that it is only a minor problem and that he or she can carry it on his or her own and does not need to take medication, the untreated inflammation may further damage the patient’s joint, with unimaginable consequences. Six weeks after the artificial hip replacement surgery, the wound and the joint capsule should have basically healed and functioned well. If the patient is still experiencing wound pain at this time, an active search for the cause is required. Generally, there are several reasons for pain more than six weeks after surgery: 1. Pain caused by infection. If the patient still has recurrent pain more than six weeks or three months after surgery, especially if there is significant intermittent pain and night pain, infection needs to be excluded first. At this time, it is necessary to actively seek medical attention, review the two indicators of blood sedimentation and C-reactive protein, and ask the chief surgeon for diagnosis and treatment; 2. Pain caused by muscle training. Six weeks after the surgery, the patient needs muscle strength training. If the training is not good, the patient will feel soreness in the hip joint or soreness near the outer hip joint after walking for a long time. At this time, the pain can be relieved by abductor exercises; 3. Other causes of pain. Sudden pain more than six weeks after surgery, or joint locking (i.e., the joint suddenly gets stuck during movement and cannot be extended and flexed, then there is usually sudden pain), you need to consider whether there is hip dislocation or fracture due to trauma, then you need to actively seek medical treatment.
