Kaplan-Meier survival analysis was used to assess arthroplasty-free survivorship.

The arthroplasty-free survivorship rate following knee arthroscopy is 83.0% at 5 years. However, at 10 years, the arthroplasty-free survivorship decreased to 66.6%. Patients without knee OA nor obesity had an arthroplasty-free survivorship of 84.1% at 5 years and 68.5% at 10 years. However, patients with a diagnosis of both knee OA and obesity based on ICD-9 and 10 codes had an arthroplasty-free survivorship of 66.2% at 5 years and 15.4% at 10 years. (HR: 2.38; 95% CI: 2.18, 2.60; p < 0.001) CONCLUSION: At five years there is an 83% rate of arthroplasty-free survivorship. This effect deteriorates at the 10-year mark, and many are eventually destined for knee arthroplasty. Presence of diagnosis codes for both knee OA and obesity are risk factors for knee arthroplasty following knee arthroscopy in patients 50 years and older.</p><p><strong>Level of evidence: </strong>IV, Prognostic, Case Series.</p>","PeriodicalId":55459,"journal":{"name":"Arthroscopy-The Journal of Arthroscopic and Related Surgery","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
