We aimed to do a national survey on the population-based incidence of patella fractures and related risk factors fracture in China.
All the data on patella fractures were available from the China National Fracture Survey (CNFS) between January and May in 2015. And in the CNFS, all eligible household members were selected from 24 urban cities and 24 rural counties of eight provinces of China, with stratified random sampling and the probability proportional to size method used. Questionnaire was sent to every participant for data collection and quality control was accomplished by our research team members.
A total of 512,187 valid questionnaires were collected, and relevant data were abstracted. There were a total of 69 patients with 69 patella fractures that occurred in 2014, indicating that the incidence was 13.5 (95% CI, 10.3-16.7))/100,000 person-years. Slip, trip, or fall from standing height was the most common cause, leading to 69.6% (48/69) of patella factures, followed by traffic accidents (18.8%, 13/69). Home and road were the first two most common places, where 86.9% of the overall injuries occurred. Age of 45-64 and 65-74 years, alcohol consumption and previous history of fractures were identified as independent risk factors for patella fracture.
Specific public health policies focusing on decreasing alcohol consumption should be implemented. Individuals aged 45-64 and 65-74 should pay more attention to bone mass density and prevention of falls, especially those with previous history of fracture.
本研究旨在对中国人群髌骨骨折的发病率及相关危险因素进行全国性调查。
所有髌骨骨折数据均来自于 2015 年 1 月至 5 月间进行的中国骨折流行病学研究（CNFS）。CNFS 采用分层随机抽样和概率比例规模法，从中国 8 个省的 24 个城市和 24 个农村县抽取合格家庭户成员作为研究对象。通过问卷收集数据，由研究团队成员完成质量控制。
共纳入 512187 份有效问卷，提取相关数据。2014 年共发生 69 例髌骨骨折，发病率为 13.5（95%CI，10.3-16.7）/100000 人年。滑倒、绊倒或由站立高度坠落是最常见的致伤原因，占 69.6%（48/69），其次为交通事故（18.8%，13/69）。家内和道路内是髌骨骨折的前两位发生场所，占总体损伤的 86.9%。45-64 岁和 65-74 岁、饮酒和既往骨折史是髌骨骨折的独立危险因素。
应制定专门的公共卫生政策，减少饮酒。45-64 岁和 65-74 岁人群应关注骨密度和预防跌倒，尤其是既往有骨折史者。
