Device for measuring tibio-femoral force amplitudes and force locations in total knee arthroplasty

摘要

A probe used during a total knee arthroplasty for measuring forces and locations of their points of application and thereby moments includes two load sensitive plates t to be inserted in one joint-compartment of a knee joint each and each being provided with a top surface and a bottom surface. At least two load sensors may be situated on the top surfaces and/or the bottom surface of each load sensitive plate.
