Brief Summary
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

Outcome Measures
Primary Outcomes (3)
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)
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.
During surgery
Precision of guided surgical actions

Study Arms (2)
Repeated Measurements of Knee Alignment and Kinematics
ACTIVE COMPARATORPatients in the Repeated Measurements Arm will have the kinematic measurement protocol repeated twice before and twice after the surgical procedure; the procedure itself will be performed with the traditional technique, i.e without guidance by the system.
Computer Guidance of Surgical Actions
ACTIVE COMPARATORPatients in the Computer Guidance of Surgical Actions Arm will have the kinematic measurement protocol performed only once before and once after the surgical procedure; the procedure itself will be performed with guidance by the system.
Interventions
