The systematic review was conducted using the keywords \u201cknee\u201d and \u201costeochondritis dissecans\u201d or \u201costeochondral lesion\u201d via a search through PubMed and Cochrane Library. All original human studies that reported on factors affecting union rates following fixation of osteochondritis dissecans of the knees were included. Nineteen studies with 512 knees were included. The union rates following surgical fixation of osteochondritis dissecans was 88% (95% confidence interval [CI]: 85\u201391%). Stability of the osteochondritis dissecans intraoperatively was the most important factor in affecting the union rates (pooled relative risk: 1.20; 95% CI: 1.07\u20131.36). No other risk factors, including skeletal maturity, gender of patients, location of osteochondritis dissecans, size of osteochondritis dissecans, open versus arthroscopic surgery, and number of fixation devices used affected the union rates following surgical fixation of osteochondritis dissecans. Surgical fixation of osteochondritis dissecans provided good union rates in majority of the patients, and stability of the osteochondritis dissecans intraoperatively was the most important factor in affecting the union rates.<\/jats:p>","DOI":"10.1055\/a-2886-8159","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T22:43:50Z","timestamp":1781822630000},"source":"Crossref","is-referenced-by-count":0,"title":["Factors affecting Union Rates following Fixation of Osteochondritis Dissecans of the Knees: A Systematic Review and Meta-Analysis"],"prefix":"10.1055","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0075-7890","authenticated-orcid":false,"given":"Si Heng Sharon","family":"Tan","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore","place":["Singapore"],"department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen Xi Kasia","family":"Chua","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore","place":["Singapore"],"department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilson Wei Yang","family":"Tham","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore","place":["Singapore"],"department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shant Qinxiang","family":"Sin","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore","place":["Singapore"],"department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew Kean Seng","family":"Lim","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore","place":["Singapore"],"department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James Hoipo","family":"Hui","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore","place":["Singapore"],"department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"S97","DOI":"10.1016\/j.otsr.2017.02.016","article-title":"Osteochondritis dissecans of the knee","volume":"104","author":"F Accadbled","year":"2018","journal-title":"Orthop Traumatol Surg Res"},{"issue":"09","key":"ref2","doi-asserted-by":"crossref","first-page":"3096","DOI":"10.1007\/s00167-020-06365-y","article-title":"The incidence and risk factors of osteoarthritis following osteochondritis dissecans of the knees: a systematic review and meta-analysis","volume":"29","author":"S HS Tan","year":"2021","journal-title":"Knee Surg Sports Traumatol Arthrosc"},{"issue":"06","key":"ref3","doi-asserted-by":"crossref","first-page":"1216","DOI":"10.1007\/s00167-013-2531-y","article-title":"Surgical management of osteochondritis dissecans of the knee in the paediatric population: a systematic review addressing surgical techniques","volume":"22","author":"M Abouassaly","year":"2014","journal-title":"Knee Surg Sports Traumatol Arthrosc"},{"issue":"08","key":"ref4","doi-asserted-by":"crossref","first-page":"2512","DOI":"10.1016\/j.arthro.2019.03.020","article-title":"Does internal fixation for unstable osteochondritis dissecans of the skeletally mature knee work?
