A suture guide may include a tissue guard and a flanking post disposed to one side of the tissue guard. The flanking post may define a plurality of channels passing through its width. The channels may be so oriented that they define suture needle guide paths in one or more planes that do not intersect the tissue guard.

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.

A fixed-bearing ankle prosthesis may include tibial and talar components whose articulating surfaces directly contact one another. The tibial component defines medial and lateral concave condylar facets separated by a convex central portion. The talar component includes medial and lateral convex condyles separated by a concave central portion. The condyles each have a single radius of curvature in a medial-lateral plane such that each condyle has a circular-arc cross-section continuously extending from the respective medial or lateral edge of the talar component to the concave central portion. The medial-lateral radii of the condyles are smaller than corresponding radii of the condylar facets.
