There is a lack of evidence of the diagnosis and treatment-related epidemiological studies of symptomatic discoid meniscus. This study analyzed the national epidemiological data for discoid meniscus in South Korea.
From 2011 to 2019, data related to the diagnosis and procedure codes of discoid meniscus were obtained from the Korean Health Insurance Review and Assessment Service database. All patients encoded as discoid meniscus were included. Data were extracted and further analyzed as follows: (1) the total number and the incidence (cases per 100,000) of discoid meniscus diagnosis per year, (2) sex distribution, (3) age distribution, (4) discoid meniscus ratio (total discoid meniscus coding per total meniscus injury coding), and (5) surgical procedures after discoid meniscus injury.
The total number of discoid meniscus diagnosed was 4576 in 2011 and increased to 6639 in 2019, representing a 45.1% increase. The incidence was 9.5 in 2011 and increased to 13.0 in 2019. Concerning sex, discoid meniscus was more common in females (55%) than in males (45%) over the study period. Regarding age, the peak age of discoid meniscus in 2011 was "under 19," whereas in 2019, the peak age was observed in the 50s. The discoid meniscus ratio range was 2.12-2.60% from 2011 to 2019. The total number of meniscectomy increased by 20% from 2000 in 2011 to 2475 in 2014. However, the total number of meniscus repairs was 318 in 2011 and increased to 502 in 2019, indicating an increase of 58%.
The total number and incidence of symptomatic discoid as well as the discoid meniscus ratio and the incidence of total discoid meniscus repair steadily increased from 2011 to 2019. The number of meniscus repair procedures increased more rapidly than that of meniscectomy. The current study helps understand the epidemiology of symptomatic discoid meniscus, its prevention, and cost-saving measures in South Korea.
目前缺乏有关症状性盘状半月板诊断和治疗相关的流行病学研究证据。本研究分析了韩国盘状半月板的全国流行病学数据。
2011年至2019年，从韩国健康保险审查和评估服务数据库中获取与盘状半月板诊断及手术编码相关的数据。纳入所有编码为盘状半月板的患者。数据提取及进一步分析如下：（1）每年盘状半月板诊断的总数及发病率（每10万人中的病例数）；（2）性别分布；（3）年龄分布；（4）盘状半月板比例（盘状半月板总编码数与半月板损伤总编码数之比）；（5）盘状半月板损伤后的手术方式。
2011年诊断出的盘状半月板总数为4576例，到2019年增至6639例，增长了45.1%。发病率在2011年为9.5，到2019年增至13.0。在性别方面，在研究期间，盘状半月板在女性中（55%）比男性中（45%）更常见。在年龄方面，2011年盘状半月板的发病高峰年龄为“19岁以下”，而在2019年，发病高峰年龄出现在五十多岁。2011年至2019年盘状半月板比例范围为2.12 - 2.60%。半月板切除术的总数从2011年的2000例增加20%至2014年的2475例。然而，半月板修复术的总数在2011年为318例，到2019年增至502例，增长了58%。
从2011年到2019年，症状性盘状半月板的总数、发病率、盘状半月板比例以及盘状半月板修复的发生率均稳步上升。半月板修复手术数量的增长速度比半月板切除术更快。本研究有助于了解韩国症状性盘状半月板的流行病学、预防措施及节约成本的措施。
