Abstract
Official abstract text for this publication.
A femoral prosthetic component comprises a pair of condyles having an intercondylar notch interposed substantially therebetween. Each of the pair of condyles comprises an edge that borders the intercondylar notch. At least one of the pair of condyles comprises a condylar notch disposed within the respective edge of the at least one of the pair of condyles.
First claim
Opening claim text (preview).
What is claimed is: 1. A femoral prosthetic component comprising: a pair of condyles including a medial condyle and a lateral condyle having an intercondylar notch interposed substantially therebetween, each of the pair of condyles comprising an edge that borders the intercondylar notch wherein the medial condyle includes a medial condylar notch forming a first recess in the edge of the medial condyle that borders the intercondylar notch and the lateral condyle includes a first lateral condylar notch forming a second recess in the edge of the lateral condyle that borders the intercondylar notch, wherein at least one of the edges of the pair of condyles is characterized by a radial arc and at least one of the first and second recesses interrupts the radial arc in the respective edge of the at least one of the pair of condyles, wherein the first and second recesses are configured to accommodate a portion of a corresponding cruciate ligament therewithin, without the cruciate ligament contacting the edge of the condyle. 2. The femoral prosthetic component of claim 1 , further including a second lateral condylar notch forming a third recess in the edge of the lateral condyle that borders the intercondylar notch. 3. The femoral prosthetic component of claim 1 , wherein the femoral prosthetic component further includes a patellar guide component coupled to each of the pair of condyles. 4. The femoral prosthetic component of claim 3 , wherein the patellar guide component and each of the pair of condyles comprise a superior surface for engagement with a surface of a femur and an inferior surface for articulation with a bearing surface of a tibial component, and further wherein the medial condylar notch and the first lateral condylar notch each traverses the superior and inferior surfaces of the corresponding condyles. 5. The femoral prosthetic component of claim 1 , wherein one of the corresponding cruciate ligaments is an anterior cruciate ligament. 6. The femoral prosthetic component of claim 1 , wherein the first and second recesses each define edges that are formed at an angle relative to the respective edge of the corresponding condyles.
