Abstract: 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.

Abstract: A trailer tipper is disclosed having a sub-frame, a deck pivotally secured to a rear portion of the sub-frame, and means for raising the deck relative to the sub-frame. A wheel assembly frame is pivotally secured to a rear portion of the sub-frame, and wheels are connected to the wheel assembly frame. An adjustable backstop is provided, having a first member affixed to the deck and a second member slidably secured to the first member and movable over a path that is substantially parallel to the deck. Front and middle stabilizers are pivotally secured to the sub-frame. In the raised position, each stabilizer rests on the deck or sub-frame disposed so that it does not extend outward from an outer side of the sub-frame.
