Abstract

A system is provided for positioning a cutting guide on a femur of a knee to make a cut along a distal end of the femur during knee surgery. The system may generally include an adjustable femoral attachment member configured to attach to a cut distal end of the femur, a cutting guide removably attachable to the femoral attachment member and configured to guide a surgical saw to make an additional cut on the distal end of the femur, and a force sensor for positioning between the femoral attachment member and a proximal end of a tibia of the knee. The force sensor may include a medial portion for sensing a medial force in the knee and a lateral portion for sensing a lateral force in the knee.
