On the 22nd of this month, there was a warm scene in the orthopedic ward of the Fifth Hospital of Harbin: the patient Zhu finished the discharge procedure, holding the hand of Director Wang Shaoqing, and said emotionally: these old legs have been suffering me for many years, and I could not walk on the ground two years ago. Now I can get off the ground after the joint replacement and surgery. Thank you, director, and thank you, medical staff, for giving me a chance to walk again. It is understood that this high flexion ceramic knee joint technology imported from Japan is at the world’s leading level, and is only available in Beijing and Shanghai, and is the first of its kind in Northeast China. The application of this technology marks a new step in the treatment of knee joint disease in the Department of Orthopedics of the Fifth Hospital. Jilin patient Zhu, female, 56 years old, had recurrent swelling and pain in the right knee for 10 years, aggravated with activity limitation for 2 years, diagnosed as: 1. rheumatoid arthritis 2. severe osteoarthritis of the right knee 3. diabetes mellitus type 2. The patient had high requirements for post-operative knee function and service life. After visiting several local hospitals in Jilin, he did not get a satisfactory treatment plan and came to the Fifth Hospital in Harbin with a view to finding Director Wang Shaoqing. Director Wang is a member of the Joint Surgery Committee of the Chinese Physicians Association and a director of the Joint Surgery Committee of the Chinese Orthopaedic Association; he has a comprehensive grasp of and the ability to perform complex artificial hip and knee joint replacement and revision surgery, periarticular osteotomy, orthopedic and other difficult surgeries. Faced with this case, Director Wang led the entire medical and nursing staff to make concerted efforts and study together. Repeated, detailed and thorough discussions and plans were made in terms of preoperative preparation, surgical plan, possible intraoperative problems, as well as postoperative care and rehabilitation. After fully improving the relevant preparations, the patient was admitted to the operating room on January 8, 2012, and the surgery was successfully completed in one hour. After the surgery, the patient was given systematic functional exercises under the careful guidance of the medical staff, and now the patient is recovering well, and the knee function is fully restored. The successful completion of this surgery filled the gap in the province’s orthopedic ceramic knee replacement cases, marking a new step in the orthopedic joint technology of the hospital, steadily entering the city and the province’s orthopedic first. It is understood that artificial knee replacement refers to the use of a prosthesis similar to the human bone joint made of metal materials with good biocompatibility and mechanical properties, using surgical methods to replace the artificial joint surface damaged by disease or injury, to remove the lesion, relieve pain, and restore the movement and original function of the joint. Knee arthroplasty is an internationally advanced method of treating knee deformities, in which a damaged joint is surgically reshaped and replaced with an artificial joint. After artificial knee replacement, elderly patients can restore knee function, and 90% of them are still satisfied after twenty years. The successful implementation of this surgery has enabled the hospital to accumulate more experience in knee arthroplasty and has also brought a boon to improve the quality of life for patients with severe rheumatoid arthritis in both knees.
