A method of pre-operative planning for an orthopaedic procedure in a patient comprising: obtaining scan data associated with a joint of the patient: preparing a three-dimensional image of the joint based on the scan data; preparing an interactive initial surgical plan based on the scan data; sending the surgical plan to a surgeon; receiving a finalized surgical plan from the surgeon; preparing an image of a patient-specific alignment guide; and making the alignment guide, wherein the alignment guide comprises a femoral alignment guide that includes: a three-dimensional inner surface shaped to contact and mate with a three dimensional portion of the joint surface of a femur of a specific patient; first and second guiding apertures each having a perimeter with a portion open toward an outside edge of the device, wherein the first and second guiding apertures are configured to receive first and second guiding pins, the guiding apertures extending through a thickness of the device; and a reinforcement area surrounding the guiding apertures and having thickness greater than the thickness of the remaining portions of the device and wherein the open portion of the first and second guiding apertures are dimensioned such that the femoral alignment guide can be removed without removing the first and second guiding pins by allowing the first and second guiding pins to exit through the open portions of the first and second guiding apertures of the femoral alignment guide. obtaining scan data associated with a joint of the patient: preparing a three-dimensional image of the joint based on the scan data; preparing an interactive initial surgical plan based on the scan data; sending the surgical plan to a surgeon; receiving a finalized surgical plan from the surgeon; preparing an image of a patient-specific alignment guide; and making the alignment guide, wherein the alignment guide comprises a femoral alignment guide that includes: a three-dimensional inner surface shaped to contact and mate with a three dimensional portion of the joint surface of a femur of a specific patient; first and second guiding apertures each having a perimeter with a portion open toward an outside edge of the device, wherein the first and second guiding apertures are configured to receive first and second guiding pins, the guiding apertures extending through a thickness of the device; and a reinforcement area surrounding the guiding apertures and having thickness greater than the thickness of the remaining portions of the device and preparing a three-dimensional image of the joint based on the scan data; preparing an interactive initial surgical plan based on the scan data; sending the surgical plan to a surgeon; receiving a finalized surgical plan from the surgeon; preparing an image of a patient-specific alignment guide; and making the alignment guide, wherein the alignment guide comprises a femoral alignment guide that includes: a three-dimensional inner surface shaped to contact and mate with a three dimensional portion of the joint surface of a femur of a specific patient; first and second guiding apertures each having a perimeter with a portion open toward an outside edge of the device, wherein the first and second guiding apertures are configured to receive first and second guiding pins, the guiding apertures extending through a thickness of the device; and a reinforcement area surrounding the guiding apertures and having thickness greater than the thickness of the remaining portions of the device and a three-dimensional inner surface shaped to contact and mate with a three dimensional portion of the joint surface of a femur of a specific patient; first and second guiding apertures each having a perimeter with a portion open toward an outside edge of the device, wherein the first and second guiding apertures are configured to receive first and second guiding pins, the guiding apertures extending through a thickness of the device; and a reinforcement area surrounding the guiding apertures and having thickness greater than the thickness of the remaining portions of the device and wherein the open portion of the first and second guiding apertures are dimensioned such that the femoral alignment guide can be removed without removing the first and second guiding pins by allowing the first and second guiding pins to exit through the open portions of the first and second guiding apertures of the femoral alignment guide.
