ABSTRACT:
A knife particularly adapted for use in removing the semilunar cartilages from the knee has an elongated handle-engaging shank and two cutting blades fixed forwardly thereon. A first of the blades is flat transversely and concave longitudinally in extension of the shank with a curvature generally conforming to the curvature of the outer surface of the meniscus, and has a cutting edge at its front end. The second blade is integrally joined to the first blade along one edge thereof and is disposed at a right angle to the concave side of the first blade, and tapers rearwardly from its forward cutting edge toward the shank. A guide member projects forwardly from the point of intersection of the cutting edges of the two blades.
