Prostheses that address stress shielding are disclosed. For instance, a knee prosthesis includes a monolithic femoral component having medial and lateral condylar elements for confronting and engaging a natural tibia or a bearing member of a tibial component, an intercondylar notch between the condylar elements for confronting and engaging a natural patella or a patellar component, and an anterior flange extending proximally from the medial and lateral condylar elements and the intercondylar notch. The femoral component defines a bone-facing surface and a bearing surface, the bearing surface including medial and lateral condylar articular surfaces defined by the medial and lateral condylar elements, respectively, and an intercondylar articular surface defined by the intercondylar notch. A slot extends through the femoral component from the bearing surface to the bone-facing surface, the slot starting at an edge of the femoral component and ending at a location within the anterior flange. Methods of making and using the prosthesis are also provided.
