All-Arthroscopic Treatment of Off-Track Hill-Sachs Lesions Using Fresh Osteochondral Allograft Plugs: "Rocks in a Stream".

Osteochondral allograft transplantation is a well-described technique for the treatment of large, engaging Hill-Sachs lesions. Traditionally, osteochondral allografts are size-matched to the defect, which can be expensive and time-consuming, and the majority of described techniques require an open approach. This Technical Note describes an all-arthroscopic approach to Hill-Sachs osteochondral allograft transplantation using premade osteochondral allograft plugs, eliminating the need for size-matching and graft harvest. This approach works not by anatomically filling the defect, but rather by bridging the defect to prevent it from engaging the glenoid.
