A method of sizing and balancing a knee including: placing an integrated orthopedic instrument in contact with a resected distal femoral surface of a femur of a knee in flexion such that medial and lateral posterior feet of a tensor frame of the instrument are in contact with posterior condyles of the femur and such that medial and lateral posterior feet of a sizer body of the instrument are positioned on a spacer placed on a resected proximal surface of the patients tibia securing first and second wings extending from a central portion of the tensor frame on the resected distal femoral surface rotating the sizer body relative to the tensor frame via a rotation mechanism that connects the sizer body and the tensor frame to balance the ligaments and sizing the patients femur by moving a stylus coupled to the sizer body on an anterior surface of the femur.
