Abstract
A surgical instrument system for use in a total knee arthroplasty includes an intramedullary rod and a reference block. The intramedullary rod is elongated between a proximal rod end and a distal rod end and is adapted for introduction into the medullary space of a femur. The reference block is or can be slid onto the distal rod end and has a block rear side oriented in a proximal direction. The block rear side is adapted to bear on distal condyles of the femur. The reference block is mounted to or mountable on the distal rod end by a bearing element having a reception bore for coaxial and radially form-fit reception of the distal rod end. The bearing element is mounted on the reference block so as to be pivotable relative thereto at least about a pivot axis oriented in an anteroposterior direction.
