Abstract
A surgical instrument for taking measurements during orthopaedic surgery such as knee replacement procedures. The instrument includes two reference elements which each have an outwardly facing registry surface. The instrument includes a measurement guide which has indicia related to a linear distance between the two registry surfaces and an angular orientation between the two registry surfaces. The reference elements are biased apart and the measurement guide responds contemporaneously with the relative movement of the two reference elements. One of the registry surfaces may be an articulating surface for engagement with a provisional femoral component. The instrument may include a housing from which two elongate members are biasingly projected to support one of the reference elements and the indicia corresponding to the angular orientation of the two registry surfaces may be a second linear measurement corresponding to the distance between the two registry surfaces at a second location.
