Clinical review demonstrates evidence-based surgical strategies for osteochondral allograft transplantation, highlighting methods to preserve chondrocyte viability and minimize immunogenicity.

Key Points

To present an evidence-based procedural strategy for osteochondral allograft preparation and delivery that maximizes tissue incorporation, cellular viability, and overall clinical outcomes.
Synthesized eight evidence-based clinical steps covering graft rewarming, saline-submerged harvesting, and subchondral bone trimming to a depth of 4 to 6 mm.
Outlined preparation methods addressing impaction forces, pulsed lavage, pressurized carbon dioxide cleansing, orthobiologic augmentation, and atraumatic suture-guided placement.
Gradual rewarming, saline-submerged cutting, and atraumatic delivery without high impaction forces limit thermal necrosis and preserve chondrocyte viability.
High-pressure pulsed lavage and pressurized carbon dioxide remove antigenic marrow elements and enhance graft porosity for orthobiologic infiltration.
Trimming bone plugs to 4–6 mm subchondral depth combined with grooving and bone marrow aspirate concentrate enhances osteogenic potential and host-graft integration.
