The authors appropriately state that their findings do not establish a benefit of BAS or negate the influence of residual obesity. We highlight several interpretive constraints. Matching on body mass index (BMI) at arthroplasty conditions on a post\u2010exposure variable, while restriction to patients who ultimately underwent arthroplasty excludes those who improved sufficiently to avoid surgery. The 95% confidence interval for 2\u2010year reintervention supports the absence of a statistically detectable difference, not equivalence or non\u2010inferiority. Two\u2010year follow\u2010up may miss later mechanical failures, and exclusion of approximately 9% of screened records, including patients with missing BMI, may introduce additional selection bias. Glucagon\u2010like peptide\u20101 (GLP\u20101) receptor agonists remain an important future perspective. Overall, the study provides useful short\u2010term conditional observational evidence among selected arthroplasty recipients with comparable BMI, rather than an estimate of the overall causal effect of BAS before knee arthroplasty.<\/jats:p>","DOI":"10.1002\/ksa.70640","type":"journal-article","created":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T16:29:06Z","timestamp":1791908946000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Previous bariatric surgery before knee arthroplasty: A cautious interpretation"],"prefix":"10.1002","author":[{"given":"Xia","family":"Qu","sequence":"first","affiliation":[{"name":"Department of Orthopedics, The Affiliated Traditional Chinese Medicine Hospital Southwest Medical University Luzhou Sichuan Province People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangxiang","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The Affiliated Traditional Chinese Medicine Hospital Southwest Medical University Luzhou Sichuan Province People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5599-4813","authenticated-orcid":false,"given":"Bo","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The Affiliated Traditional Chinese Medicine Hospital Southwest Medical University Luzhou Sichuan Province People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,13]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ksa.70523"},{"issue":"4","key":"e_1_2_6_3_1","doi-asserted-by":"crossref","DOI":"10.1001\/jamanetworkopen.2022.6722","article-title":"Effect of bariatric surgery on risk of complications after total knee arthroplasty: a randomized clinical trial","volume":"5","author":"Dowsey MM","year":"2022","journal-title":"JAMA Netw Open"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2026.06.039"},{"issue":"4","key":"e_1_2_6_5_1","doi-asserted-by":"crossref","first-page":"1085","DOI":"10.1016\/j.arth.2025.08.073","article-title":"Short\u2010term complications of preoperative weight loss strategies in total knee arthroplasty: bariatric surgery versus glucagon\u2010like peptide\u20101 receptor agonists","volume":"41","author":"Sharma A","year":"2026","journal-title":"J Arthroplasty"}],"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ksa.70640","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ksa.70640","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ksa.70640","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T16:29:07Z","timestamp":1791908947000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1002\/ksa.70640"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,13]]},"references-count":4,"alternative-id":["10.1002\/ksa.70640"],"URL":"https:\/\/doi.org\/10.1002\/ksa.70640","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"value":"0942-2056","type":"print"},{"value":"1433-7347","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,13]]},"assertion":[{"value":"2026-07-27","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-09-14","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-10-13","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"ksa.70640"}}
