Embodiment Construction

[0021] It should be noted that, in many of the figures, the cut surface created by the cutting tool in accordance with the techniques of the present invention are shown as having already been completed for the sake of clarity. Similarly, the bones may be shown as being transparent or translucent for the sake of clarity. The guides / pins, cutting tool, bones, and other items disclosed are may be similarly represented for the sake of clarity or brevity

FIGS. 1 Through 4

[0022]FIGS. 1 and 2 show conventional surgical exposures and instrumentation being utilized. FIG. 4 shows a reduced incision currently utilized in performing the current state of the art in ‘minimally invasive’ Unicondylar Knee Replacement.

FIGS. 5 Through 11

[0023]FIGS. 5 through 11 concentrate on alignment guide and / or drill guide techniques. FIG. 5 shows a manually operated alignment guide suitable for use with surgical exposures similar to that shown in FIG. 2 (it should be noted that surgical navigation sensors cou...

Abstract

Alignment guides, cutting guides, cutting tools and soft tissue management techniques for profile based resection (PBR) arthroplasty facilitate intraoperative and postoperative efficacy and ease of use. In one embodiment, a manual alignment guide is provided that permits less invasive incisions by providing soft tissue accommodating contours or reliefs. In another embodiment, a single medial drill guide plate is used for the PBR arthroplasty.
