We describe a low-cost new hybrid workstation for osteochondral allograft transplantation based on modified Ilizarov components and its clinical application in a patient with a large osteochondral femoral defect. The technique was applied in a 28-year-old male with chronic knee pain following two prior failed arthroscopic surgeries. Osteochondral allograft transplantation was performed using our modified workstation instrumentation. At the 8-month follow-up, MRI revealed excellent incorporation of the graft, and the patient reported ambulation without pain with return to physical activity. Our hybrid workstation presents a cost-effective alternative for graft preparation while maintaining a high standard of surgical care.<\/jats:p>","DOI":"10.3390\/jpm16040187","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T08:22:36Z","timestamp":1774858956000},"page":"187","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Osteochondral Allograft Transplantation of the Knee Using a Low-Cost Custom Hybrid Workstation Instrumentation: Technical Note with an Illustrative Case"],"prefix":"10.3390","volume":"16","author":[{"given":"Danijel","family":"Jurkovi\u0107","sequence":"first","affiliation":[{"name":"Sestre Milosrdnice University Hospital Centre, 10000 Zagreb, Croatia"},{"name":"University of Applied Health Sciences, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3682-617X","authenticated-orcid":false,"given":"Stjepan","family":"Ivandi\u0107","sequence":"additional","affiliation":[{"name":"Sestre Milosrdnice University Hospital Centre, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomislav","family":"\u010cengi\u0107","sequence":"additional","affiliation":[{"name":"Sestre Milosrdnice University Hospital Centre, 10000 Zagreb, Croatia"},{"name":"University of Applied Health Sciences, 10000 Zagreb, Croatia"},{"name":"School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5732-1150","authenticated-orcid":false,"given":"Stipe","family":"\u0106orluka","sequence":"additional","affiliation":[{"name":"Sestre Milosrdnice University Hospital Centre, 10000 Zagreb, Croatia"},{"name":"School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1177\/0363546509352157","article-title":"Focal cartilage defects in the knee impair quality of life as much as severe osteoarthritis: A comparison of Knee injury and Osteoarthritis Outcome Score in four patient categories scheduled for knee surgery","volume":"38","author":"Heir","year":"2010","journal-title":"Am.
