Linear regression was used to evaluate injurytrends.</p><p><strong>Results: </strong>There were 832 cases (NE: 27469) of LE injuries in male ice hockey players from 2013-2022. Linear regression demonstrated increasing LE injuries in the post-COVID period (after the year 2020). The knee (34.7%, NE: 9,533) and ankle (29.4%, NE: 8,089) were most commonly injured. The most frequent injuries for the ankle (35.8%) and knee (30.5%) were strains/sprains. Skating sprains (15.1%, NE: 4,157) and slip and/or falls (14.2%, NE: 3,898) were the most common primary mechanisms of injury. Slip and/or falls (40.8%) and collisions with another player (23.9%) were most common secondarymechanisms of injury. Slip and/or falls, collisions with another player,and checking commonly injured the knee. There were no significant changes in ininjury incidence at any anatomical location or primary mechanism of injury overthe study period.</p><p><strong>Conclusion: </strong>The knee and ankle were the most common location of lower extremityinjuries in male ice hockey players between 2013-2022. The knee was vulnerable to a variety of primary mechanisms ofinjury, including checking, collisions with other players, and slip and/or falls. Despite implementation of urgent orthopedic carecenters, allowance of additional foot protection, and facility improvements, the rate of post-COVID LE injuries have been increasing.</p>","PeriodicalId":51268,"journal":{"name":"Physician and Sportsmedicine","volume":" ","pages":"319-327"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143371424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
