Abstract

Various embodiments are directed to base components that are usable with implantable mechanical energy absorbing systems. According to one embodiment, the base component includes a low-profile body having a elongate, straight portion at a first end and a curved body portion at a second end. The second end is elevated as compared to the first end. An inner surface of the low-profile body has a raised portion extending along the elongate, straight portion of the low-profile body. The base component also includes a plurality of openings positioned along the low-profile body for alignment and purposes of affixation to body anatomy.

Claims

1. An implantable mechanical extra-articular apparatus comprising:

a pair of bases, at least one of said bases having an inner surface which follows the contours of a lateral side of a first bone of a knee joint in an inferior/superior direction and an anterior/posterior direction;

the at least one base having a fixation portion with at least two fixation holes and a curved arm portion with a thickness sufficient to be elevated compared to the fixation portion to create a space adjacent the lateral side of the first bone of the knee joint; and

an extra-articular implantable mechanical energy absorbing system attached to an end of the curved arm portion opposite the fixation portion.

2. The apparatus of claim 1, further comprising a plurality of openings positioned on the at least one base, wherein the openings define bores having differing trajectories and are sized to receive fastening members.

3. The apparatus of claim 2, further comprising:

a plurality of bone screws.

4. The apparatus of claim 1, further comprising:

bone promoting treatment on the inner surface of the at least one base, the treatment being selected from the group consisting essentially of bone morphogenic protein 2, hydroxyapatite, titanium beads, and cobalt chrome beads.

5. The apparatus of claim 1, further comprising:

bone promoting treatment on surfaces of the base, the treatment altering the surface roughness, porosity, or chemical composition at said surfaces.

6. The apparatus of claim 1, wherein the at least one base is configured to be positioned entirely outside a joint capsule of the knee joint.
