Dr. Su has been researching methods to improve and enhance the recovery from TKR ever since his training was completed in 2003. As patients typically experience pain and swelling after TKR surgery, Dr. Su has been investigating ways to diminish these sensations so that recovery can be more rapid. This includes: pre-emptive analgesia, performed by the anesthesiologist prior to surgery...
Arthritis of the knee is a condition in which there is loss of the articular cartilage of the femur, tibia, or patella. This can be seen on x-ray as a loss of the space between the two ends of bone. Because of the loss of the gliding surfaces of the bone, people with arthritis may feel as though their knee is stiff and their motion is limited.
Minimally invasive surgery (MIS) for total knee replacement refers to the technique of performing the procedure through a smaller incision, as well as handling the tissues as gently as possible. The work done to replace the knee with an artificial implant (sawing, cutting, and preparing the bone) is similar to the way it has always been done, but the instruments used to do so are more streamlined, allowing surgeons to perform the operation through a smaller incision.
People often wonder when and why they should have their knee replaced. This is an individualized question that depends upon a person's activity level and functional needs. Many people with arthritis live with pain that prevents them from participating in activities that they love; others are so debilitated that they have difficult putting on their shoes and socks.
Total knee replacement surgery is considered major surgery, but every precaution is taken to make the procedure as safe as possible. As with any surgical procedure, there are risks with being placed under anesthesia. You will meet the anesthesiologist taking care of you prior to the surgery and be able to discuss the specific risks of anesthesia.
Dr. Su is one of a handful of surgeons who uses computer navigation for all of his knee replacement operations. Computer navigation is an enabling technology that provides real-time, intraoperative information to a surgeon, in order to perform the operation with greater precision.
