| 摘要 |
An artificial knee joint includes a femoral component (11), provided with a medial condyle (13), a lateral condyle (14) and a front flange (50). The medial condyle (13) and the lateral condyle (14) are joined together in proximity with the rear end of the intercondyle groove (19) by a femoral cam (17), and separated by the intercondyle groove (19) in the remaining part of their extension. A tibial component includes a tibial plate and a tibial insert (12). The tibial insert (12) is configured to support the medial condyle (13), and the lateral condyle (14), and is provided with a tibial post (18). The femoral cam (17) is asymmetrical and comprises a distal surface (20) shaped like a drum which articulates with the tibial post (18). |

1. Artificial knee joint, comprising:
a femoral component (11), able to be attached to a distal end of a femur, provided with a medial condyle (13), a lateral condyle (14) and a front flange (50), said medial condyle (13) and said lateral condyle (14) being joined together in proximity with the rear end of the intercondyle groove (19) by a femoral cam (17), and separated by said intercondyle groove (19) in the remaining part of their extension; a tibial component suitable to be attached to a proximal end of a tibia, comprising a tibial plate and a tibial insert (12), said tibial insert (12) being provided with a medial articulation surface (15) to support said medial condyle (13), and with a lateral articulation surface (16) to support said lateral condyle (14), and with a tibial post (18) substantially positioned on the longitudinal center of said tibial insert (12), wherein said femoral cam (17) is asymmetrical and comprises a distal surface (20) shaped like a drum which articulates with said tibial post (18). |
