One of the major concerns that some people face when they are asked if you haven't had surgery, they say I have diabetes. Then we tell them whether your sugar is under control or not, and they say yes, I have been taking pills for years and it is under control. Note that sugar slightly increases the risk of possible complications, but it has a degree and severity, and if it has been under control in different years, the risk is not so low that we want to ignore knee pain and the benefits of knee joint replacement and say that I have diabetes and did not have surgery. There are many different measures that can be taken to control blood sugar before or after surgery. The techniques used today have made it possible for people with diabetes to perform surgery. The patient should only be visited by the doctor and the consulting team, who is definitely an endocrinologist, and his sugar will be controlled.
