We aimed to describe demographic, socioeconomic, and regional characteristics of individuals undergoing HA in Sweden based on nationwide registry data compared with an age- and sex-matched reference population, and to describe regional variation in the annual incidence of HA using nationwide registry data.Methods:\u00a0We conducted a nationwide descriptive registry study including all individuals aged 18\u201365 years who underwent HA in Sweden between 2006 and 2018. Each individual was matched by sex and year of birth to 5 reference individuals from the general population. National registers provided information on demographics, region of residence, education, citizenship, employment status, income, and compensated sick leave.Results:\u00a0The study included 4,633 individuals undergoing HA and 23,060 matched reference individuals. Mean age was 36 years, and 3,019\/4,633 (65%) were men. Residence-based HA incidence was highest in metropolitan and nearby counties. Individuals undergoing HA more often had post-secondary education (1,874\/4,633 [40%] vs 8,003\/23,060 [35%]), employment before surgery (4,299\/4,633 [93%] vs 19,267\/23,060 [84%]), and high-income levels (1,996\/4,633 [43%] vs 7,358\/23,060 [32%]) than the reference population. Compensated sick leave was more common among individuals undergoing HA both before surgery (741\/4,633 [16%] vs 1,614\/23,060 [7%]) and during the year after surgery (1,436\/4,633 [31%] vs 1,845\/23,060 [8%]).Conclusion:\u00a0Individuals undergoing HA were more often employed and belonged to higher-income groups than a matched reference population. HA incidence varied substantially between regions, and individuals undergoing HA demonstrated higher levels of compensated sick leave both before and after surgery.<\/jats:p>","DOI":"10.2340\/17453674.2026.46648","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T15:49:33Z","timestamp":1790178573000},"source":"Crossref","is-referenced-by-count":0,"title":["Hip arthroscopy in Sweden: a nationwide registry study of socioeconomic characteristics, regional variation, and sick leave patterns"],"prefix":"10.2340","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4765-520X","authenticated-orcid":false,"given":"Miriam G","family":"Wadstr\u00f6m","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6261-2024","authenticated-orcid":false,"given":"Anders","family":"St\u00e5lman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5555-0876","authenticated-orcid":false,"given":"Tobias","family":"W\u00f6rner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frida","family":"Eek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3233-2638","authenticated-orcid":false,"given":"Nils P","family":"Hailer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesper","family":"Kraus-Schmitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasmin D","family":"Hailer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"169227","doi-asserted-by":"crossref","unstructured":"Frank J M, Harris J D, Erickson B J, Slikker III W, Bush-Joseph C A, Salata M J, et al.
