Characteristics of rotating high-flexion prosthesis for the middle-aged patients with knee osteoarthritis in total knee replacement / 中国组织工程研究

ABSTRACT

BACKGROUND:Total knee replacement is the main treatment for the end of the knee joint disease. How to choose prosthesis replacement according to the different situations of the patient is one of the focuses in the field of joint surgery. OBJECTIVE: To evaluate middle or short term effects of rotating high-flexion prosthesis for the middle-aged patients with osteoarthritis of knee in total knee replacement. METHODS: We retrospectively analyzed 48 osteoarthritis patients (55 knees) undergoing total knee replacement with rotating high-flexion prosthesis in the Liuzhou People’s Hospital from January 2009 to January 2013. RESULTS AND CONCLUSION:(1) Forty-eight patients were folowed up for 23-42 months, mean (24±2.7) months. (2) Knee range of motion and Hospital for Special Surgery knee score were significantly increased after implantation. The excelent and good rate of Hospital for Special Surgery knee score was 85.4%. (3) No infection, loosening or dislocation occurred in al patients. (4) These findings suggest that curative effect of rotating high-flexion prosthesis is definite. After implantation, the range of motion was high, which was accorded with movement pattern of the human body. Prosthesis has a long life, and its repair rate is low. It is an ideal method for the middle-aged patients who want to perform high-flexion activities.
