BACKGROUND: Femoroacetabular impingement (FAI) is increasingly recognized as a significant cause of hip and groin pain. Despite the rising awareness, epidemiological data on FAI remain limited in East Asia. This study aimed to investigate the prevalence, treatment patterns, and associated medical costs of FAI in South Korea. METHODS: To identify patients with FAI, a nationwide claims database from the Korean Health Insurance Review and Assessment Service (HIRA) was used from January 2013 to December 2022. The patients were identified using the International Classification of Diseases, 10th Revision codes for FAI. Patients aged 15 years and older were grouped into 5-year age intervals and categorized according to gender. The overall crude and age-adjusted prevalence were assessed from 2013 to 2022 using the Korean Statistical Information Service (KOSIS). Patients were further categorized into those undergoing surgical treatment and conservative treatments. To assess the economic burden of the disease, we estimated the total medical and out-of-pocket costs reimbursed for patients diagnosed with these codes. RESULTS: During the study period, 39,620 patients were considered to have the diagnosis of FAI. Among them, 2,884 patients were hospitalized, including 1,562 men and 1,322 women. The number of hospitalized patients slightly decreased from 303 in 2013 to 281 in 2022. However, the total number of patients increased significantly from 2,721 in 2013 to 5,196 in 2022. When stratified by age in 5-year intervals, a bimodal distribution was observed for men and an unimodal distribution for women, with a peak in the 50s. The age-adjusted prevalence showed an annual increase of 7.14% (95% confidence interval [CI], 4.56-10.22; < 0.001), rising from 5.94 per 100,000 (95% CI, 5.70-6.17) to 10.40 per 100,000 (95% CI, 10.11-10.68). Despite rising overall patient numbers, the proportion undergoing surgical treatment declined from 11.1% to 5.4%. Total medical costs increased by 43% for men and 27% for women from 2013 to 2022. CONCLUSION: This study highlights the significant increase in FAI prevalence and related healthcare costs in South Korea. However, only a minority of FAI patients underwent surgical treatment during the study period.
背景：股骨髋臼撞击症（FAI）日益被认为是髋部和腹股沟疼痛的重要原因。尽管人们的认识不断提高，但东亚地区关于FAI的流行病学数据仍然有限。本研究旨在调查韩国FAI的患病率、治疗模式及相关医疗费用。 方法：为识别FAI患者，我们使用了韩国健康保险审查和评估服务机构（HIRA）2013年1月至2022年12月的全国索赔数据库。通过国际疾病分类第10版中FAI的编码来识别患者。15岁及以上的患者按5岁年龄间隔分组，并按性别分类。利用韩国统计信息服务机构（KOSIS）评估2013年至2022年的总体粗患病率和年龄调整患病率。患者进一步分为接受手术治疗和保守治疗的两类。为评估该疾病的经济负担，我们估算了被诊断为这些编码的患者的总医疗费用和自付费用。 结果：在研究期间，39620名患者被认为患有FAI。其中，2884名患者住院，包括1562名男性和1322名女性。住院患者数量从2013年的303例略有下降至2022年的281例。然而，患者总数从2013年的2721例显著增加至2022年的5196例。按5岁年龄间隔分层时，男性呈现双峰分布，女性呈现单峰分布，峰值出现在50多岁。年龄调整患病率显示每年增加7.14%（95%置信区间[CI]，4.56 - 10.22；P < 0.001），从每10万人5.94例（95% CI，5.70 - 6.17）升至每10万人10.40例（95% CI，10.11 - 10.68）。尽管患者总数总体上升，但接受手术治疗的比例从11.1%降至5.4%。2013年至2022年，男性的总医疗费用增加了43%，女性增加了27%。 结论：本研究凸显了韩国FAI患病率及相关医疗保健成本的显著增加。然而，在研究期间只有少数FAI患者接受了手术治疗。
