<p>A device for determining a cutting plane at the proximal end of the tibia, including a telescoping rod (10) having means (16, 18, 20) at each end for attachment to the proximal end of the tibia and to the malleoli, and a cutting guide (24) pivotably mounted about a shaft (28) perpendicular to the rod and supported by a ring (30) slidably mounted on said rod. The device is useful for defining a cutting plane that is perpendicular to the proximal epiphyseal axis of the tibia, or parallel to the lower condylar plane of the femur, when the knee is straight and looseness due to bone wear is reduced.</p> |
