1. A system for performing femoral resections for a partial knee arthroplasty, the system comprising:
a surgical robot comprising an articulating arm configured to move within a coordinate system for the surgical robot;
a femoral resection guide instrument comprising:
a coupler for connecting to the articulating arm;
an extension arm extending from the coupler; and
a resection block attached to the extension arm the resection block including a guide surface for performing a resection of a distal surface of a single condyle of a distal femur; and
a finishing guide separate from and releasably couplable to the femoral resection guide instrument for performing a posterior resection of the single condyle of the distal femur, wherein the finishing guide can be intraoperatively attached to and separated from the femoral resection guide instrument by a user;
wherein the finishing guide is positionable by the surgical robot to determine a thickness and rotation of the posterior resection;
wherein the finishing guide comprises a resection block body comprising:
a first surface for facing bone;
a second surface opposite the first surface;
a first resection surface configured to perform a posterior femoral resection when the first surface is positioned to engage flush with the resected distal surface; and
a second resection surface configured to perform a chamfer resection when the first surface is positioned to engage flush with the resected distal surface:
wherein the first resection surface and the second resection surface extend from the first surface to the second surface through the resection block body; and
wherein the first resection surface and the second resection surface are located a fixed distance from each other.
