Alignment guides, cutting guides, cutting tools and soft tissue management techniques for profile based resection (PBR) arthroplasty facilitate intraoperative and postoperative efficacy and ease of use. In one embodiment, a manual alignment guide is provided that permits less invasive incisions by providing soft tissue accommodating contours or reliefs. In another embodiment, a single medial drill guide plate is used for the PBR arthroplasty.

1. A method of implanting an orthopedic prosthesis during knee arthroplasty surgery, comprising: providing a femoral prosthesis having a fixation surface for facing a femur and an articulation surface adapted to articulate with a surface associated with a tibia;positioning opposing guide patterns along opposing sides of a distal portion of the femur, the guide patterns possessing cutting tool guide surfaces geometrically corresponding to a geometry of the fixation surface of the femoral prosthesis;fixing the opposing guide patterns in position relative to the femur;positioning a cutting tool mediolaterally between the femur and the tibia;engaging the cutting tool with the cutting tool guide surfaces;manipulating the tibia through a range of motion about the femur while simultaneously actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis; andoperably attaching the femoral prosthesis to the resected surface. 2. The method of claim 1, wherein the step of manipulating the tibia through a range of motion about the femur while simultaneously actuating the cutting tool includes preventing a cutting profile of the cutting tool from being exposed to soft tissue regions adjacent respective sides of the femur with a pair of soft tissue protective sleeves, each soft tissue protective sleeve surrounding the cutting tool proximate one of the soft tissue regions and biased to track along a contour of one of the sides of the femur. 3. The method of claim 1, wherein the step of actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis is accomplished with a single pass of the cutting tool. 4. The method of claim 1, wherein the step of actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis is accomplished with two passes of the cutting tool. 5. The method of claim 1, wherein the step of fixing the opposing guide patterns in position relative to the femur includes extending fixation features from the guide patterns into holes in the femur through an incision in soft tissue adjacent the femur. 6. The method of claim 5, wherein the step of fixing the opposing guide patterns in position relative to the femur includes fixing the opposing guide patterns such that only the fixation features extend through the incision. 7. A method for implanting an orthopedic prosthesis during knee arthroplasty surgery comprising: providing a femoral prosthesis having a fixation surface for facing a femur and an articulation surface adapted to articulate with a surface associated with a tibia;positioning a medial guide pattern along a medial side of a distal portion of the femur, the guide pattern possessing cutting tool guide surfaces geometrically corresponding to a geometry of the fixation surface of the femoral prosthesis;fixing the medial guide pattern in position relative to the femur;positioning a cutting tool mediolaterally between the femur and the tibia;engaging the cutting tool with the cutting tool guide surfaces;manipulating the tibia through a range of motion about the femur while simultaneously actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis; andoperably attaching the femoral prosthesis to the resected surface. 8. The method of claim 7, wherein the step of manipulating the tibia through a range of motion about the femur while simultaneously actuating the cutting tool includes preventing a cutting profile of the cutting tool from being exposed to soft tissue regions adjacent respective sides of the femur with a pair of soft tissue protective sleeves, each soft tissue protective sleeve surrounding the cutting tool proximate one of the soft tissue regions and biased to track along a contour of one of the sides of the femur. 9. The method of claim 7, wherein the step of actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis is accomplished with a single pass of the cutting tool. 10. The method of claim 7, wherein the step of actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis is accomplished with two passes of the cutting tool. 11. The method of claim 7, wherein the step of fixing the medial guide pattern in position relative to the femur includes extending fixation features from the guide pattern into holes in the femur through an incision in soft tissue adjacent the femur. 12. The method of claim 11, wherein the step of fixing the medial guide pattern in position relative to the femur includes fixing the guide pattern such that only the fixation features extend through the incision. 13. A method for implanting an orthopedic prosthesis during knee arthroplasty surgery comprising: providing a femoral prosthesis having a fixation surface for facing a femur and an opposing articulation surface adapted to articulate with a surface associated with a tibia;creating an incision in soft tissue adjacent to a distal portion of the femur;positioning a guide pattern adjacent to the incision, the guide pattern possessing cutting tool guide surface geometrically corresponding to a geometry of the fixation surface of the femoral prosthesis;fixing the guide pattern in position relative to the femur;positioning a cutting tool mediolaterally between the femur and the tibia;engaging the cutting tool with the cutting tool guide surfaces;manipulating the tibia through a range of motion about the femur while simultaneously actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis; andoperably attaching the femoral prosthesis to the resected surface. 14. The method of claim 13, wherein the step of engaging the cutting tool with the cutting tool guide surfaces includes extending a soft tissue protective sleeve surrounding a portion of the cutting tool through the soft tissue and into contact with the femur. 15. The method of claim 14, wherein the step of manipulating the tibia through a range of motion about the femur while simultaneously actuating the cutting tool includes maintaining the soft tissue sleeve in contact with the femur. 16. The method of claim 13, wherein the step of actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis is accomplished with a single pass of the cutting tool. 17. The method of claim 13, wherein the step of actuating the cutting tool to cut the femur to form a resected surface for the femoral prosthesis is accomplished with two passes of the cutting tool. 18. The method of claim 13, wherein the step of fixing the guide pattern in position relative to the femur includes extending fixation features from the guide pattern through the incision into holes in the femur. 19. The method of claim 18, wherein the step of fixing the guide pattern in position relative to the femur includes fixing the guide pattern such that only the fixation features extend through the incision.
