工作背景：半月板手术是最常见的骨科手术，尽管最近强调保留半月板，但半月板手术的现状在许多国家（包括日本）鲜为人知。日本国家健康保险索赔和特定健康检查数据库和公共健康保险医疗活动统计数据库通过健康保险索赔跟踪半月板手术。国家数据库提供了2014年和2015年的数据，医疗活动统计数据提供了2011年6月至2016年6月的数据。本研究的目的是基于国家数据库，分析各年龄组的孤立半月板手术数量和半月板修复率，并根据医疗活动统计数据评估最近6年半月板修复率的趋势。方法：从国家数据库中统计2014-2015年各年龄组的半月板手术数量，计算半月板修复率（半月板修复/半月板手术）。这些数字也来自2011-2016年医疗保健活动统计数据。对于半月板修复率的年度趋势的统计分析，使用Cochran-Armitage趋势检验。结果：根据国家数据库，2015年，半月板手术共34，966例，患者高峰年龄在青少年晚期和60多岁。2014年半月板修复率为19%，2015年为24%。根据医疗活动统计，2011年半月板修复率为9%，2016年显著增加至25%（p = 0.0008）。在20岁出头至70岁后期的每个年龄组中，该比率也显著增加。结论：日本每年约有35，000例半月板手术，高峰年龄在青少年后期和60岁。半月板修复的数量在过去六年中有所增加。(C)2018作者由Elsevier B.

Background: Meniscus surgery is the most commonly performed orthopedic surgery, and despite recent emphasis on saving the meniscus, the current status of meniscus surgeries is little known in many countries, including Japan. The National Database of Health Insurance Claims and Specific Health Checkups of Japan and the Statistics of Medical Care Activities in Public Health Insurance track meniscus surgeries through health insurance claims. The National Database provides the numbers for 2014 and 2015, and the Statistics of Medical Care Activities provides the numbers from June 2011 to June 2016. Our aim was to analyze isolated meniscus surgery numbers and meniscus repair ratios by age group based on the National Database and evaluate trends of meniscus repair ratios for the latest six years from the Statistics of Medical Care Activities.Methods: Meniscus surgeries by age group were counted from the National Database for 2014-2015, and meniscus repair ratios (meniscus repairs/meniscus surgeries) were calculated. The numbers were also counted from the Statistics of Medical Care Activities in 2011-2016. For statistical analysis of annual trends of meniscus repair ratios, the Cochran-Armitage trend test was used. Meniscus surgeries with concomitant knee ligament surgeries were excluded.Results: According to the National Database, isolated meniscus surgeries totaled 34,966 in 2015, with peak ages of patients in their late teens and 60s. The meniscus repair ratio was 19% in 2014 and 24% in 2015. According to the Statistics of Medical Care Activities, the meniscus repair ratio was 9% in 2011 and significantly increased to 25% in 2016 (p = 0.0008). The ratio also increased significantly in each age group between the early 20s and late 70s.Conclusions: Approximately 35,000 meniscus surgeries are performed in Japan annually, with peak ages in the late teens and 60s. The number of meniscus repairs has increased over the past six years. (C) 2018 The Authors. Published by Elsevier B.V. on behalf of The Japanese Orthopaedic Association.
