There were no differences in self-reported pain scores (<i>F</i> = 0.027; <i>P</i> = 0.97), ADL (<i>F</i> = 0.256; <i>P</i> = 0.78), or QoL (<i>F</i> = 0.120; <i>P</i> = 0.88) between any groups. In addition, the frequency of effusion-synovitis was as follows: for the right limb, Grade 0 = 35 (66%), Grade 1 = 15 (28%), Grade 2 = 1 (2%), and Grade 3 = 2 (4%); for the left limb, Grade 0 = 31 (58%), Grade 1 = 19 (36%), Grade 2 = 3 (6%), and Grade 3 = 0 (0%).</p><p><strong>Conclusion: </strong>The presence of effusion-synovitis, irrespective of being unilateral or bilateral, was not associated with self-reported knee pain in elite female athletes. This suggests that lower grades of effusion-synovitis may not significantly impact knee pain.</p><p><strong>Clinical relevance: </strong>The findings of this study challenge existing assumptions about the impact of effusion-synovitis on knee pain in athletes, contributing to the nuanced understanding of knee joint health in sports medicine.</p>","PeriodicalId":54276,"journal":{"name":"Sports Health-A Multidisciplinary Approach","volume":" ","pages":"19417381251323902"},"PeriodicalIF":2.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11951132/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143722448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
