Abstract
Spreader apparatuses for knee joints are shown which have two parallel support plates (2, 3) which can be inserted between the femur condyles (4, 5) and the tibia (6) and which can be moved apart in connected form by an adjustment mechanism (10). The adjustment mechanism (10) has a housing (10) at which a stroke-extending tappet (17) is supported via an elastically resilient transmission member (7) in order to simultaneously make the effective spreading travel readable on a scale (8) at the housing (1) and the amount of the spreading force readable on a scale (9) at the housing (1).
