A reduction-based orthopedic system facilitates the installation of a properly oriented prosthetic component of the type having an articulating surface adapted to co-act in a joint. A trialing component attachable to an anchoring unit includes an articulating surface corresponding to that of the prosthetic component, enabling a desired orientation to be established through a trial reduction. A cutting guide is provided which is physically indexed to the trialing component and the prosthesis, such that when the bone is modified using the guide, the prosthetic component automatically assumes the desired orientation. The apparatus invention may further include apparatus for locking the trialing component into place upon establishing the desired orientation, with the anchoring unit being rigidly coupleable to the anchoring unit bone through attachment to the trialing component in locked position. In an alternative configuration, the bone-cutting guide is coupleable to the anchoring unit through direct attachment.
