The number of knee arthroplasties and the prevalence of obesity are increasing exponentially. To date there have been no published reviews on utilization rates of knee arthroplasty in OECD countries.
We analysed economic, medical and population data relating to knee arthroplasty surgeries performed in OECD countries. Gross domestic product (GDP), health expenditures, obesity prevalence, knee arthroplasty utilization rates and growth in knee arthroplasty rates per 100,000 population were assessed for total population, for patients aged 65 years and over, and patients aged 64 years and younger.
Obesity prevalence and utilization of knee arthroplasty have increased significantly in the past. The mean utilization rate of knee arthroplasty was 150 (22-235) cases per 100,000 total population in 2011. The strongest annual increase (7%) occurred in patients 64 years and under. Differences between individual countries can be explained by economic and medical patterns, with countries with higher medical expenditures and obesity prevalence having significantly higher utilization rates. Countries with lower utilization rates have significantly higher growth in utilization rates. The future demand for knee prostheses will increase x-fold by 2030, with exact rates dependant upon economic, social and medical factors.
We observed a 10-fold variation in the utilization of knee arthroplasty among OECD countries. A significant and strong correlation of GDP, health expenditures and obesity prevalence with utilization of knee arthroplasty was found. Patients aged 64 years and younger show a two-fold higher growth rate in knee arthroplasty compared to the older population. This trend could result in a four-fold demand for knee arthroplasty in OECD countries by 2030.
膝关节置换手术的数量和肥胖症的患病率呈指数级增长。迄今为止，尚未有关于经合组织国家膝关节置换手术利用率的公开综述。
我们分析了与经合组织国家进行的膝关节置换手术相关的经济、医学和人口数据。评估了总人口、65岁及以上患者以及64岁及以下患者的国内生产总值（GDP）、医疗支出、肥胖症患病率、膝关节置换手术利用率以及每10万人口中膝关节置换手术率的增长情况。
过去，肥胖症患病率和膝关节置换手术的利用率显著增加。2011年，膝关节置换手术的平均利用率为每10万总人口150例（22 - 235例）。64岁及以下患者的年增长率最高（7%）。各国之间的差异可以通过经济和医学模式来解释，医疗支出较高且肥胖症患病率较高的国家，其利用率显著更高。利用率较低的国家，其利用率的增长率显著更高。到2030年，膝关节假体的未来需求将增加x倍，具体增长率取决于经济、社会和医学因素。
我们观察到经合组织国家之间膝关节置换手术的利用率存在10倍的差异。发现GDP、医疗支出和肥胖症患病率与膝关节置换手术的利用率之间存在显著且强烈的相关性。与老年人群相比，64岁及以下患者的膝关节置换手术增长率高出两倍。这一趋势可能导致到2030年经合组织国家对膝关节置换手术的需求增长四倍。
