Abstract
An insert for use in a knee prosthesis is disclosed. In one embodiment, the insert includes a medial compartment and a lateral compartment. The medial compartment includes a top surface having a concave surface or curve with a more posterior sulcus and increased anterior lip. The lateral compartment includes a top surface having at least a segment or portion with a convex surface or curve. Thus arranged, the insert is arranged and configured to provide improved stability for varying grades of PCL deficiencies compared to existing inserts that have a mid-line sulcus and lateral convexity. In addition, the insert provides improved lateral posterior translation compared to existing designs with a concave or flat lateral articulation that lack a lateral posterior convexity.
