ABSTRACT:
A bicompartmental tensiometer for use in prosthetic knee surgery, and in particular for use in revision knee surgery. The tensiometer comprises two parallel, independently operable jaws which are inserted between resected surfaces on the distal femur and the proximal tibia. The jaws are opened manually by the surgeon until the proper tension is placed on the collateral ligaments. Each of the jaws comprises two paddles which remain parallel to each other as they are opened. Moreover, the two jaws remain parallel to each other, or in the same angular orientation, when adjusted to be placed adjacent the condyles. Each jaw is held open by a pawl which engages a rack.
