Osteochondral Allograft Transplantation of the Knee Using a Low-Cost Custom Hybrid Workstation Instrumentation: Technical Note with an Illustrative Case

Osteochondral allograft transplantation is a safe and effective surgical option for the treatment of large, focal, full-thickness chondral and osteochondral defects, particularly in young patients. 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.
