1. An orthopedic outing guide apparatus suitable for use in preparing the distal end of a femur in knee arthroplasty, said femur having an anterior surface, a posterior surface, and a distal-most end surface, said apparatus comprising:
- a. an adjustable cutting guide block comprising a first section secured to a second section;
wherein said first section further comprises an anterior face integral with a proximal end, a distal face integral with a posterior end, and medial and lateral sides, and wherein said second section comprises a distal face, an anterior end, a posterior end, and medial and lateral sides;
b. said first section further comprising a post integral with and extending from said posterior face of said first section, said post comprising at least one hole configured to maintain a fastener;
said second section further comprising a receptacle communicating through said anterior end and oriented in registration with said post, said receptacle configured to maintain said member therein, said second section further comprising at least one hole through said distal face in communication with said receptacle, wherein when said post is engaged within said receptacle, one of said at least one hole of said post may be aligned in registration with one of said at least one hole in said second section of said cutting guide, thereby securing said sections of said guide to one another via said fastener at a desired position upon said femur, thereby providing for adjustability in length of the cutting guide block in the anterior/posterior direction with respect to said femur;
c. said first section further comprising a series of slots configured to engage a cutting saw to provide cuts at desired locations upon said femur in preparation of said femur for attachment of a prosthetic implant thereto; and
d. said second section further comprising a series of slots configured to engage a cutting saw to provide cuts at desired locations upon said femur in preparation of said femur for attachment of a prosthetic implant thereto.

Abstract
Novel cutting guides and surgical methods for use in knee arthroplasty are described. Embodiments of the inventive cutting guide apparatus include fixed and adjustable cutting guide blocks having a series of slots designed to accommodate a cutting saw. The cutting guides and surgical method are designed to allow for the provision of all desired surgical cuts upon the distal end of the femur, for subsequent implantation of a prosthesis thereto, without having to remove the cutting guide block.
