Study 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

Eligibility

Primary outcome measure(s)

• 3D knee kinematic assessment — 1 day
  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)
• Precision of guided surgical actions — During surgery
  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.
• Precision of guided surgical actions — On post-operative imaging (six weeks after surgery)
  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.
