Femoral and tibial base components
First Claim
1. An implantable mechanical extra-articular system for a knee joint including a joint capsule, comprising:
- an absorber, the absorber absorbs a predetermined compression load applied to the knee joint; and
a base having two ends, an upper surface, an inner surface opposite the upper surface and a mounting surface,wherein the inner surface includes a bone contacting surface configured to engage and attach to exterior surfaces of bone, and a non-contacting surface displaced vertically from the bone contacting surface and closer towards a portion of the upper surface overlaying the non-contacting surface so as to be offset from exterior surfaces of the bone,wherein the mounting surface alone is configured to operatively engage and connect to the absorber, and wherein the mounting surface is located at one of the two ends with all portions of the mounting surface elevated above the bone surface to position the absorber outside the joint capsule.

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.
