1. An implantable suture anchor for wedging within a bore formed in a bone to secure a suture to the bone, said suture anchor comprising:

  • a body having a generally quadrilaterally shaped lateral cross-section, said body comprising;

    a bore-abutting surface having opposed ends;

    a leading gripping edge at one end of the bore-abutting surface the leading gripping edge comprising the intersection of a leading surface with the bore-abutting surface at an acute angle;

    a trailing gripping edge at the end of the bore-abutting surface opposite the leading gripping edge the trailing gripping edge comprising the intersection of a trailing surface with the bore-abutting surface at an acute angle; and

    a closing surface having an arcuate portion and a substantially linear portion, the arcuate portion engaging the leading surface and the substantially linear portion engaging the trailing surface so as to generally form a quadrilateral, the closing surface being disposed generally opposite the bore-abutting surface for facilitating the rotation of the body about the leading gripping edge within the bore;

    said body further defining;

    a suture bore extending transversely therethrough adjacent the trailing gripping edge; and
