As the population ages, more and more people are experiencing knee pain, swelling, limited range of motion, and twisted pronation due to joint degeneration, rheumatism, trauma, etc. When the symptoms seriously affect your daily life, you will need a total knee replacement to help you resolve this inconvenience. Once you have undergone a series of tests to determine your need for a total knee replacement and are physically fit for the procedure, you will be admitted to our hospital for a total knee replacement. We will design your knee surgery and explain the surgical plan to you and your family based on your frontal and lateral knee x-ray, knee CT, or knee MRI, and we will select a prosthesis based on the condition of your cruciate ligament, the degree of bone loss, and the state of soft tissue contracture around the joint. The anesthesiologist will select the anesthesia according to your specific situation to minimize side effects while ensuring the effectiveness of the anesthesia, and we will perform the surgery according to the pre-operative plan and fit you with the selected prosthesis. We usually use an anteromedial approach to access the joint cavity, remove the peri-articular soft tissue and bone tissue, followed by osteotomy module for lateral femoral and tibial osteotomies and joint balance reconstruction, followed by fitting the prosthesis and closing the wound layer by layer. Early and adequate functional exercise after knee arthroplasty is essential for the recovery of the patient’s joint function. The postoperative exercises should follow a sequence from less to more, from light to heavy, and in a gradual manner. While exercising adequately, it is important to avoid discomfort symptoms such as swelling and bleeding due to exercise, which requires specific mediation by the patient according to his or her condition.
