From the realm of universal medical ethics, doctors have only the obligation to see and treat their patients, not the right to choose them at will. What I want to talk about here are several choices that doctors face in the actual medical process. 1. Doctors should choose the right patient for the right treatment. Generally speaking, among people suffering from hip and knee diseases, only patients with really serious lesions, really obvious symptoms and significantly reduced quality of life have indications for artificial joint surgery. Because joint replacement is the last step of choice, other treatments that work within certain limits (e.g. maintenance, medications, physical therapy, intra-articular injections, arthroscopic debridement for mild to moderate patients) should not be ruled out and patients should not be easily and hastily replaced with artificial joints. At present, there are still from time to time in the doctor’s surgical indications are too wide, for the replacement of joints and joint replacement of medical behavior, these are undesirable; 2, doctors should choose their own ability to treat patients for treatment. Artificial joint surgery is quick to get started and the relatively low threshold has accelerated the development and popularity of hip and knee joint replacement surgery, but it has also brought about many problems. In some common cases that I encountered in my clinical work, the surgery was completed, but some of them could be seen from the postoperative X-ray alone that it was a not very qualified surgery. For some difficult cases, there are often more problems. In fact, the clinical requirements for a qualified joint surgeon are very high, and most of our doctors rush into the field without specialized theoretical and practical training in the field of joint replacement. As a physician, it is worthwhile to promote the spirit of self-challenge, but in the spirit of responsibility for the patient, one should not easily implement medical practices that are beyond one’s capabilities. In my mind, another criterion of “” is to refer patients beyond one’s ability to other; 3. Doctors want to choose patients with whom they can understand each other for treatment. In the current medical environment and doctor-patient relationship, this actually applies universally, but more so in the case of artificial joint surgery. This is because the artificial joint will be with the patient for life, and the patient will need to be followed up on a regular basis, so a responsible joint surgeon will also be “with” the patient for life. It is only through mutual trust and understanding between the surgeon and the patient that the entire process of treatment can continue. For the surgeon, the patient should not be considered a “burden” and neglected to follow up. For the patient, it is also necessary to understand the special nature of artificial joint surgery. It is like a high jumper trying to reach a new height and always failing, or a goalkeeper in a soccer game who, even if he can keep more balls, the door he is guarding will eventually open again and again. However, it is inevitable to face a series of long-term failures such as osteolysis and prosthesis loosening, which will eventually require revision surgery, or even multiple complex revisions. As a doctor, you should consider the artificial joint patient as your own valuable “treasure”; and as a patient, you should understand that joint surgeons often have to put several times more time and effort into themselves than doctors of other specialties. In short, only by trying to improve the mutual understanding and trust between doctors and patients can we get out of the current complicated medical atmosphere. As a surgeon specializing in artificial joints, I will make unremitting efforts to this end!
