The method of claim 1, wherein passing the distal end of the first inserter through the meniscal tear further includes piercing the meniscal tissue with the distal end of the first inserter that is carrying the first anchor on an exterior of the first inserter. 19. The method of claim 18, wherein the first anchor includes a first end and a second end, the first and second ends of the first anchor being proximal to the distal end of the first inserter, where the distal end of the first inserter forms a passage through the meniscal tissue to carry the first anchor. 20. A method for repairing a meniscal tear in meniscal tissue comprising: positioning a distal end of a cannula adjacent to a first side of the meniscal tear at a first location;passing and positioning a distal portion of a first elongated shaft carrying a first anchor through the cannula to the first location;piercing the meniscus with a distal end of the distal portion of the first elongated shaft, where the first anchor is positioned proximal the distal end to carry the first anchor from the first side of the meniscal tear to a second side of the meniscal tear at a second location on an outer surface of the meniscal tissue;retracting the first elongated shaft to deploy the first anchor at the second location;positioning the distal end of the cannula adjacent to the first side of the meniscal tear at a third location;passing and positioning a distal portion of a second elongated shaft carrying a second anchor through the cannula to the third location;piercing the meniscal tissue with a distal end of the distal portion of the second elongated shaft, where the second anchor is proximal the distal end to carry the second anchor from the first side of the meniscal tear to the second side of the meniscal tear at a fourth location on an outer surface of the meniscal tissue;retracting the second elongated shaft to deploy the second anchor at the fourth location; andreducing the meniscal tear by tightening a flexible strand coupling the first and second anchors. 21.
