Abstract
Improved coring devices suitable for articular cartilage and bone, wherein the cutting device is capable of slicing through a tough protective tangential zone, delicately separating the shock absorbing columns of cells in the radial zone of the cartilage, and finally cutting into the hard underlying bone in a manner that preserves the viability of osteochondral cells. The coring device features an annulus having a flat annular cutting edge interrupted by at least one serration having neutral cutting angles. A method for concurrently removing cartilaginous and bony tissue using an improved coring device that preserves the viability of osteochondral cells.
