AUGUST 2022 | The Surgical Technologist | 359 Kostretzis et al. Kinematic Alignment Total Knee Revision FIGURE 6 | (A) Post-revision standing long-leg X-ray of the left lower limb where the implant mDFA has been modified to 2.0◦ valgus and the mPTA at 3.0◦ varus (1.0◦ varus aHKA). As expected, the femoral cemented stems is not aligned with the femoral bone diaphysis. On the tibial side, to restore patient’s alignment, only a stubby stem could be used and comes in contact with the lateral cortex. (B) Left knee lateral view where the implant posterior tibial slope has been reduced to 3.0◦. Because manufacturer recommendations for this implant is a neutral slope, we did not aim at patient’s contra-lateral side value of 6◦.
