Claim 0:
1. A method, comprising:
resecting a distal end of a femur of a knee joint;
placing a reference surface of a housing against the resected distal end of the femur, the housing being elongated along a longitudinal axis, the reference surface defining a plane that includes the longitudinal axis, the reference surface further defining a flexion/extension axis as being parallel to the plane and perpendicular to the longitudinal axis; and
setting a reference orientation of the housing against the resected distal end of the femur by actuating a reference orientation element on the housing,
the housing including a rotation sensor configured to measure a flexion/extension position of the housing,
the flexion/extension position being a relative rotational position about the flexion/extension axis with respect to the reference orientation,
the housing including a flexion/extension display located on the housing and configured to visually represent the measured flexion/extension position.
