Tips and Pearls

Position the patient in the lateral decubitus position for treating glenoid defects because it eliminates the effects of gravity when implanting the scaffold.

Position the rotator interval portal slightly laterally. This allows a perpendicular trajectory to the defect when performing microfracture.

Debride the entire layer of calcified cartilage without penetrating the subchondral bone. An arthroscopic shaver may be used for this step.

Use a PowerPick to obtain short, uniform-diameter holes that are less likely to crack at the edges of the holes.

When the paste mixture of micronized allograft cartilage and PRP is too dry, making it difficult to handle, consider adding a small amount of additional PRP.
