Compared to people with normal weight and mental function, participants with overweight/obesity only had 1.5-times higher odds of both high-intensity pain and disability (95%CI(1.19–1.97); (1.12–1.99) respectively). Those with overweight/obesity and impaired mental function had 4.2-times (95%CI 2.97–5.93) higher odds of high-intensity pain and 2.9-times (95%CI 2.11–4.16) higher odds of high disability compared with participants without overweight/obesity or impaired mental function.</div></div><div><h3>Conclusions</h3><div>These findings highlight that among individuals with overweight or obesity significantly impaired physical and mental functions are important in identifying those at risk of having high-intensity back pain and high disability 14 years later. Examining changes in weight and physical and mental health over time is warranted and targeting these factors together may help reduce the huge burden of back pain in the community.</div></div>","PeriodicalId":74377,"journal":{"name":"Osteoarthritis and cartilage open","volume":"7 2","pages":"Article 100604"},"PeriodicalIF":0.0,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After removal of duplicates, abstract screening, and full text reading, 251 articles were included in the final review. MRI is the most common modality employed to assess knee synovitis, followed by US imaging. Varied imaging techniques used in the assessment of joint synovitis may be targeting divergent constructs of synovial remodeling and inflammation, which complicates interpretation of results.</div></div><div><h3>Conclusions</h3><div>There is no consensus on the best method for imaging of knee synovitis in OA. Future work may benefit from the evaluation of synovitis separate from joint effusion, and their associations with histologic findings to discriminate between features of synovial inflammation and remodeling.</div></div>","PeriodicalId":74377,"journal":{"name":"Osteoarthritis and cartilage open","volume":"7 2","pages":"Article 100602"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
