Sheath disassembly and intraoperative arthroscopic images corresponding to the right hip in Figure 1. (A) The curved shaver is disassembled by applying pressure against the sterile back table until the angle of curvature is slightly reduced. This allows the inner sleeve (blue) to be removed from the outer sheath (red) with relative ease. (B) The outer sheath is loaded with bone graft (BG), and the inner sleeve is used as a plunger until the bone graft can be seen exiting the side-opening. The outer sheath may then be manipulated against the back table to the desired degree of curvature before inserting into the joint for bone graft application. (C) Viewing through the mid-trochanteric portal with a 30° arthroscope, a curved shaver sleeve (yellow asterisk) loaded with bone graft is inserted through the mid-anterior portal in preparation for bone grafting of the cystic cavities (white asterisks). (D) Viewing through the mid-trochanteric portal with a 30° arthroscope, a curved shaver sleeve (yellow asterisk) is placed with the side-opening of the shaver sleeve facing the cystic cavity to deliver the bone graft. Air bubbles are seen as the inner sleeve of the curved shaver is deployed as a plunger to deliver the bone graft and pressurize the cystic cavity. (E) Viewing through the mid-anterior portal with a 30° arthroscope, a well-positioned bone graft can be seen within the loculated cystic cavity in the well-contained articular cartilage defect.
