 Good morning, I am Dr. Gurdeep Singh, Senior Consultant Orthopedics and Joint Replacement, Manipal Hospital, Gurgaon. Today I am here to give a small talk on total knee replacement and I hope that some of the misconceptions of total knee replacement are cleared with this small talk. So what exactly is a knee replacement? Hip replacement and knee replacement is different from a liver or a kidney transplant. In a liver or kidney transplant, we put a donor's liver or kidney in the patient. In the knee replacement and hip replacement, joint patient remains the same. Only the surface of the knee that has been damaged, we change that. So in the knee replacement, thigh bone and leg bone surface 8mm is replaced by a metallic titanium implant, that is all, that is done in a knee replacement. The joint patient remains the same. The two joints, rheumatoid arthritis, injury or any other reason, are damaged. We replace that and do a knee replacement. This is a disease of the elderly. A young man's joint is generally not so bad that he needs a knee replacement. And there is no upper limit. We have even replaced the 90-year-old patient. The main point of contention is whether the patient is fit for surgery or not. So if anesthetically and cardiacly the patient is fit, he can undergo surgery at any age. This is a model of a knee joint. Normally, our joint is smooth like this. Slowly, slowly, as if the hair is white. Similarly, the joint is always the same. And it becomes arthritic. Gradually, the arthritis progresses to a stage wherein you need a knee replacement. This is a knee replacement implant where just the surface 8mm of the bone is replaced by a metallic implant. The patient can walk from the next day of the surgery. For two to three weeks, we call a walker or stick to walk with the patient. Once the patient is confident, then he can walk without any support. There is no contraindication to this surgery. Even if the patient is very heavy or heavy, we can do this surgery. If the patient's heart function is fine and the patient is fit for anesthesia, then any patient can undergo a knee replacement surgery. This is a routine procedure. There is no blood loss during surgery. We do it under tourniquet control. We make the patient sit and walk the next day. And for the third or fourth day, the patient can go home and do their normal routine activities. We only refuse to do two things to the patient. One, you won't sit on the ground with your alfalfa. Second, you won't use an Indian toilet. Other than this, you can climb stairs. You can climb on the bus. You can resume all your normal activities which you were unable to do because of the knee pain. This is a surgery which is done to improve the quality of your life. And I would suggest that instead of suffering from knee pain, any patient who needs a knee replacement should undergo a knee replacement. Thank you.
