Abstract
An assembly (10) for use in knee replacement surgery comprising a tibial base plate (14) which, in use, engages a tibia (200), and a tensioning element (33), (34) operable, in use, to engage between the tibial base plate (14) and a femur (300) to set the gap between the tibial base plate (14) and the femur (300) when the femur (300) and tibia (200) are in extension.

1-43. (canceled)
A ligament tensioning and gap measuring device, comprising:
- a tibial base plate;
- a tensioning arrangement comprising a central tensioning element configured to engage an intercondylar notch of the femur in use, upwardly applying pressure thereon to tension the lateral and medial ligaments;
- and
- a measuring arrangement for engaging lateral and medial condyles when the ligaments are tensioned by the central tensioning element.

A ligament tensioning and gap measuring device, comprising:
- a tibial base plate which, in use, engages a tibia;
- and
- a tensioning arrangement comprising a central element operable, in use, to engage a femur and set a gap between the tibial base plate and the femur when the femur and tibia are in extension and thereby apply tension to lateral and medial ligaments;
- and
- a measurement arrangement operable, in use, to engage the lateral and medial condyles of a femur to independently measure the position of each condyle relative to the tibial base plate.
