The effects of defect size, orientation, and location on subchondral bone contact in oval-shaped experimental articular cartilage defects in a bovine knee model.

Purpose: Chondral defects of the knee may lead to pain and disability, often requiring surgical intervention. The purpose of this study was to identify how size, location, and orientation influences subchondral bone contact within oval-shaped chondral defects.

Methods: Full-thickness defects were created in twelve bovine knees.

The effects of lesion size and location on subchondral bone contact in experimental knee articular cartilage defects in a bovine model.

Purpose: To determine how femoral condyle chondral defect size and location influence subchondral bone contact within the defect.

Methods: Full-thickness, circular chondral defects (0.2 to 5.
