Abstract

See full text

A tibial spacer paddle comprises a spacer block comprising opposing bearing surfaces, an alignment slot extending into the spacer block; and a handle extending from the spacer block. The spacer block can include feet for passively engaging the femur or pegs for actively engaging a femoral component so that the spacer block is linked to the femur while the tibia rotates. A tibial spacer system comprises a provisional component having an alignment tab extending from a body and an alignment indicator located on the body, a femoral component and a pin extending from the femoral component. The pin can engage the alignment tab so that the provisional component is linked to the femur while the tibia rotates. In addition to or alternatively to the alignment tab and pin, the provisional component can include a tibial plate that can be rotationally connected to the provisional component.
