    摘要： An orthopaedic knee prosthesis includes a tibial insert and a femoral component configured to articulate on the tibial insert. The tibial insert includes a lateral articular surface and medial articular surface that is asymmetrically shaped relative to the lateral articular surface. The medial articular surface is shaped to reduce anterior translation of a medial condyle of the femoral component, while the lateral articular surface is shaped to allow a lateral condyle of the femoral component to pivot, relative to the medial articular surface, along an arcuate articular path. Additionally, one or both condyles of the femoral component may include a femoral articular surface having a curved femoral surface section defined by a continuously decreasing radius of curvature.

    摘要： An orthopaedic surgical instrument including a polymer 4-in-1 femoral cutting block having a chamfer cutting slot defined therein, and a chamfer cutting guide assembly secured within the chamfer cutting slot. The chamfer cutting guide assembly includes a first planar surface, a second planar surface spaced apart from, and extending parallel to, the first planar surface, a third planar surface connected to the second planar surface and extending at an angle relative to the first planar surface and a fourth planar surface connected to the first planar surface and extending parallel to the third planar surface. The first planar surface and the second planar surface define a first metallic planar cutting guide, and the third planar surface and the fourth planar surface define a second metallic planar cutting guide. The chamfer cutting guide assembly may include a pair of metallic bushings.

    摘要： An orthopaedic surgical device for determining the joint force of a patient's knee joint includes a tibial paddle shaped to be positioned in the patient's knee joint and a handle extending from the tibial paddle. The tibial paddle includes a sensor array positioned therein and configured to generate sensor signals indicative of the joint force of the patient's knee joint. The orthopaedic surgical device also includes a control circuit configured to control a display located on the handle to provide a visual indication of the medial and lateral balance of the joint force. In some embodiments, various tibial trialing components may be coupled to the tibial paddle along with an associated adaptor.
