Abstract: A screw, driving device, and method are provided for repairing a tissue injury of a patient, such as a meniscal tear in a knee or osteochondritis dissecans. The screw has a root, a distal section having a narrowing cross section toward the distal end, and a thread along at least a portion of the root between the proximal end and the distal end. Along a leading section extending from the distal end, the helical pitch is substantially constant; along a trailing section between the leading section and the root's proximal end, the helical pitch decreases. The substantially constant pitch along the leading section assists in preventing a stripping of the helical section. At the proximal end is a head having a diameter greater than a major root diameter of the central section. The head is for improving the tissue retention characteristics of the screw.
