Having an artificial knee replacement does not mean that you can rest easy. Patients must have regular follow-up examinations to monitor the condition of their joints. Generally speaking, within the first year after the artificial knee replacement, you need to go to your primary surgeon for three reviews, six weeks, six months, and one year; after one year of surgery, patients can be reviewed every one to two years depending on their recovery. In this case, when you come to the hospital for a follow-up six weeks after surgery, you do not need to take pictures. This follow-up is to assess the patient’s degree of flexion, whether the rehabilitation training has achieved the expected goal, etc., and then to provide targeted guidance to the patient for effective rehabilitation exercises. When the patient is reviewed again six months after surgery, the need for radiographs will be considered at the patient’s discretion; and for reviews beginning one year later, radiographs will be required to check the recovery status. It is worth noting that patients should bring all the information, especially the preoperative, postoperative, and recent X-ray films, to the follow-up appointment, so that the doctor can assess the patient’s recovery by comparing the X-ray films. As for other tests, such as blood sedimentation, C-reactive protein and other blood tests, they are not mandatory for each follow-up visit, but should be done when necessary, such as when there is abnormal pain or suspected infection. As for the bone density test, it is not a test related to knee replacement, but older patients with osteoporosis may consider having it done. In addition, patients are advised to scan the doctor’s QR code to access the doctor’s online workstation and upload medical records and other relevant information. This will help the doctor understand the patient’s current disease status, and the progression of the disease, and provide timely guidance. In general, for post-knee replacement patients, uploading x-rays is most important. Other tests such as labs, if available, can also be uploaded. TIPS: It is important to upload X-rays, not just the paper report, but also the photos. But how to take a qualified X-ray and make sure the doctor can see it clearly?
