2023 Annual Meeting Biologics-Downsizing of Precut Osteochondral Allograft Cores

Downsizing of Precut Osteochondral Allograft Cores

Video Transcription

Video Summary

Catherine Logan presents a technique for downsizing pre-cut osteochondral allograft (OCA) cores, addressing medium-sized lesions (6-8mm) that are too large for OATS yet smaller than typical available cores (starting at 10mm). The method involves placing a 10mm OCA core in a 10.5mm sizing block and using an 8mm donor harvester to reduce it to the appropriate size, ensuring a proper fit. Key steps include standard arthrotomy, precise recipient site preparation, use of biologics like PRP or BMAC, and careful insertion to achieve a flush surface, optimizing biological and structural repair for osteochondral defects.
