Patent ID: 7736367

Claim:
A cutting block mountable on a distally facing surface of a femur for guiding a saw blade making bone cuts on the distal femur comprising: a body having at least three sections spaced in an anterior-posterior direction, each section having a planar proximally facing surface for being placed adjacent to a distally facing femoral surface and a distally facing surface; and a single rib integrally formed with said body and connecting said at least three sections, said rib centrally located between a medial side and a lateral side of the block and integral with said distally facing surface of each of said sections, said rib spacing said sections to form guide slots between a central section and adjacent first and second sections for receiving the saw blade, said rib having a proximally facing surface adjacent said guide slots between said central section and said adjacent first and second sections spaced distally from said distally facing surface of said sections to form a gap therebetween; wherein said first and second sections each include a guide slot surface, a hollow interior forming a chamber, and a plurality of openings which connect said chamber to said guide slot surface; and wherein said guide slot surfaces on said first and second sections are oriented at different angles with respect to the distally facing femoral surface.
