Patients achieved an average Musculoskeletal Tumor Society scoring system of 92.4% (standard deviation 5.2; range 80-100) in the sixth postoperative month. Musculoskeletal Tumor Society scores in the recurrent patients decreased from an average of 90% to 75.3% after the final intervention.</p><p><strong>Conclusion: </strong>Intralesional curettage and cementation seem safe and reliable techniques with low recurrence and complication rates in treating low-grade chondrosarcomas of the appendicular skeleton. Clinical, radiological, and pathological evaluations are mandatory before surgical intervention, and a multidisciplinary approach is crucial. A strict follow-up regimen in the early postoperative period is needed and strongly recommended to detect local recurrence.</p><p><strong>Level of evidence: </strong>Level IV, Therapeutic Study.</p>","PeriodicalId":7097,"journal":{"name":"Acta orthopaedica et traumatologica turcica","volume":"56 6","pages":"402-407"},"PeriodicalIF":1.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/8f/8b/aott-56-6-402.PMC9885716.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10731453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
