A suture guide may include a base, a first tissue guard extending from the base, and two flanking posts affixed to the base on opposite sides of the tissue guard. The posts may extend from the base, and each of the posts may define a plurality of channels passing through its width. The channels may be so oriented that, for each post (a) the channels define suture needle guide paths in one or more planes, and (b) at least one channel passes through the first flanking post in a direction that is not parallel to a width axis W passing through the width of the first flanking post, so that it defines an oblique suture needle guide path. The first tissue guard may be connected to the base by a connector so adjustable as to control spacing between the posts and the first tissue guard.
