Fig 2.

Arthroscopic visualization from the lateral portal in a left shoulder with the patient in the beach-chair position. To harvest healthy cartilage from the chondral defect, a 3-mm shaver connect to a harvesting device can be used (A). Using the curette, cartilage can be collected from the chondral walls of the defect edges in a circumferential manner until there is vertical rim bordering the defect (B-D). These can be pulled out of the portal while just sticking to the curette. Alternatively, a grasping forceps can be used. The lesion is measured using a probe (E) and then dried with a swap (F). (HH, humerus head.)
