Abstract:
BACKGROUND:Knee osteoarthritis is prevalent among the middle-aged and senior people in Asian countries, however, the epidemiology survey of total knee arthroplasty is rarely reported in China.
OBJECTIVE: To retrospectively analyze the data of patients undergoing total knee arthroplasty from 2008 to 2013 in Hefei City, and explore the distribution of age and gender of these patients.
METHODS: A retrospective analysis among patients undergoing total knee arthroplasty from January 1st 2008 to December 31st 2013 in Hefei City was performed. Data were extracted from the database of Medical Records Room of Relevant Hospitals in Hefei City, including the patient’s gender, age, disease duration, education level, body mass index and surgical site. In addition, more clinical information in one hospital were selected and analyzed, to compare the difference of clinical features between men and women.
RESULTS AND CONCLUSION:From 2008 to 2013, totaly 1 146 patients underwent total knee arthroplasty due to knee osteoarthritis. The rate of total knee arthroplasty increased over the 6 years and was much higher in women than in men. The single-centre registry data revealed that there was no difference in age, disease duration, education level, and body mass index and surgical site between men and women. Our findings indicate that, the rate of total knee arthroplasty is increasing steadily from 2008 to 2013 in Hefei City and is higher in women than in men. Risk factors that account for such disparity in total knee arthroplasty utilization need to be further investigated.
