摘要：
A surgical apparatus is configured to support at least one bone cut for installation of a prosthetic component. The installed prosthetic component will have reduced alignment error. The surgical apparatus is configured to distract a first compartment to a first predetermined load value while allowing a moving support structure to pivot freely. A distraction lock mechanism is then engaged to prevent movement of a distraction mechanism that raises or lowers the moving support structure relative to a fixed support structure. The moving support structure has M-L tilt angle that is measured. A M-L tilt mechanism is engaged to forcibly equalize the first and second compartments. Engaging the M-L tilt mechanism prevents the moving support structure from freely pivoting. The at least one bone cut relates to the first and second compartments equalized and the M-L tilt angle.
