Problem: Currently, no system allows precise kinematic assessment of the knee and accurate guiding of orthopedic surgical actions in a minimally invasive fashion. However, such a system would prove useful in the clinical setting to improve the quality of surgical interventions at the knee. Hypothesis: A novel knee kinematic assessment and surgical guidance tool using 3D personalized imaging and minimally invasive bony fixation allows precise kinematic assessment and surgical guidance in the routine clinical setting. Objectives : * Demonstrating the capacity of the system to precisely measure 3D knee kinematics * Quantifying the reproducibility of the kinematic measurements * Measuring the impact of knee surgical procedures on knee kinematics * Assessing the correlations between measured articular kinematics and clinical results after knee surgery * Integrating the novel measuring system to the surgical flow of three knee surgical procedures * Quantifying the precision and reproducibility of the surgical actions guided by the system * Comparing the clinical results of surgeries guided by the system to those performed with the traditional technique

3D knee kinematic assessment
The system should be able to precisely and reproducibly measure 3D knee kinematics (tibio-femoral flexion, abduction-adduction, transverse rotation, and anterio-posterior and medio-lateral translations)
Time frame: 1 day
Precision of guided surgical actions
The system should allow the surgeon to realize surgical actions, like bone cuts and guide-wire placement, within one degree and one millimeter of the desired target.
Time frame: During surgery
Precision of guided surgical actions
The system should allow the surgeon to realize surgical actions, like bone cuts and guide-wire placement, within one degree and one millimeter of the desired target.
