Smart alignment tool for knee mosaicplasty surgery

Abstract

The Smart Alignment Tool for Knee MosaicPlasty Surgery is a device that aids in aligning the MosaicPlasty harvesting chisel with the cartilage surface of the knee. In the standard arthroscopic procedure, the angle at which the graft is harvested and inserted is determined visually by the surgeon through a single endoscopic view. The ability of the surgeon to obtain and place these grafts in an orientation perpendicular to the cartilage surface determines, in large part, the efficacy of the procedure. By instrumenting the tool, the angle of the tool relative to the surface is fed back to the surgeon. Preliminary experiments show this greatly increases the accuracy and consistency of this task.
