A single-center retrospective cohort study was conducted to investigate surgically treated patients for knee OCD between 1993 and 2007. A total of 37 patients with an average follow-up duration of 14 years (range 8\u201318) were in the final cohort. IKDC and Lysholm scores were assessed. The duration and types of sport activity were reported. Long-term results were compared with existing midterm data. Knee scores showed a very good outcome with a mean of 91.3 in the IKDC score and 91.7 in the Lysholm score. Compared to midterm outcomes, both IKDC (p = 0.028) and Lysholm scores (p = 0.01) improved on final follow-up. Patients with open physes showed a significantly better Lysholm score compared to patients with closed physes (p = 0.034). Defect localization and size did not influence the outcome, but a defect depth of &lt;0.8 cm2 achieved significantly better scores than \u22650.8 cm2. Of all surgical interventions, refixation achieved the best outcome. Long-term results significantly improved compared to midterm results with a follow-up of 40 months (p = 0.01). Thirty-six out of 37 patients were physically active, with 56% of sports being knee-straining activities. Long-term results following surgically treated OCD fragments show excellent function and a good athletic level. Patients with open physes potentially have better knee outcomes. Midterm results are sustainable and could improve further in the long term.<\/jats:p>","DOI":"10.3390\/jcm12124140","type":"journal-article","created":{"date-parts":[[2023,6,20]],"date-time":"2023-06-20T01:59:30Z","timestamp":1687226370000},"page":"4140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Long-Term Outcome and Athletic Level following Operative Treatment for Osteochondritis Dissecans of the Knee in Pediatric and Adolescent Patients"],"prefix":"10.3390","volume":"12","author":[{"given":"Yannic","family":"Bangert","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Heidelberg University Hospital, 69118 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Zarembowicz","sequence":"additional","affiliation":[{"name":"Department for Orthopaedic and Trauma Surgery, BG Klinik Ludwigshafen, 67071 Ludwigshafen am Rhein, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karoly","family":"Engelleiter","sequence":"additional","affiliation":[{"name":"Department for Orthopaedic and Trauma Surgery, Helios Clinic, 75175 Pforzheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evangelos","family":"Gkarilas","sequence":"additional","affiliation":[{"name":"Department for Orthopaedics, Trauma and Spinal Surgery, Neckar-Odenwald Clinics, 74821 Mosbach, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holger","family":"Schmitt","sequence":"additional","affiliation":[{"name":"German Joint Center, ATOS Clinic Heidelberg, 69115 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Renkawitz","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Heidelberg University Hospital, 69118 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayham","family":"Jaber","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Heidelberg University Hospital, 69118 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"346","DOI":"10.1177\/1947603517715736","article-title":"Osteochondritis Dissecans: Etiology, Pathology, and Imaging with a Special Focus on the Knee Joint","volume":"9","author":"Bruns","year":"2018","journal-title":"Cartilage"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1107","DOI":"10.1007\/s11999-013-2824-y","article-title":"The Classic: On loose bodies in the joint. 1887","volume":"471","year":"2013","journal-title":"Clin.
