摘要： Apparatuses and methods for microfracture (e.g., forming a plurality of microfractures in a bone to encourage cartilage regeneration). Some of the present apparatuses and methods are configured to create microfractures with smaller transverse dimensions (e.g., diameters) and greater depths than previously known. Some of the present apparatuses and methods comprise a penetrator removal tab coupled to the penetrator and configured to retract the penetrator relative to the cannula.

摘要： Microfracture apparatuses with a cannula and a penetrator. The cannula has a first end, a second end, and a channel extending between the first end and the second end through which a penetrator can move between a retracted and an extended position substantially without rotation of the penetrator. The cannula has a primary portion and a distal portion between the primary portion and the second end, with the distal portion configured such that the distal portion and/or the second end of the channel is disposed at a nonparallel angle relative to the primary portion, for example, with a curve between the primary portion and the distal portion. The penetrator is configured to flex around such a curve and/or to flex to align with the angle of the send end of the channel and/or the distal portion of the cannula.
