3D Kinematic Assessment of the Human Knee During Physical and Daily Life Activities

Problem : Precise and personalized 3D knee kinematic assessment during physical and daily life activities is a challenge; therefore, it was never performed on an important number of individuals. However, a better understanding of 3D knee kinematics during such activities would allow a better understanding of this often injured joint.

Hypothesis: A new system using personalized 3D bone imaging and a percutaneous bone fixation device that can be used under local anesthesiaallows for precise and reproducible assessment of 3D knee kinematics during physical and daily life activities.

Objectives :

* To study human knee 3D kinematics during dynamic activities using a novel minimally invasive measuring system * Investigate the correlations between standard clinical knee laxity tests and measured 3D knee kinematics during dynamic activities

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients awaiting knee arthroscopy under local anesthesia for a medial meniscal tear

  • Severe swelling of the knee
  • Knee flexion contracture
  • Knee flexion less than 120 degrees
  • Gross limping
  • Inability to perform the various motor tasks required by the study protocol

Treatment and study plan

3D knee kinematic assessment under local anesthesia

Device

3D knee kinematic assessment under local anesthesia

Primary outcomes

  1. 3D knee kinematics

    Time frame: On the day of the surgery, before knee arthroscopy

    The investigators will investigate if 3D knee kinematics can be precisely and safely measured under local anesthesia during various motor tasks (walking, squatting, pivoting, jumping): kinematic data will be analyzed in search of signs of artefact movement and kinematic aberrations, which would indicate problems with the measurement system.

Secondary outcomes

  1. Correlation of kinematic data with clinical laxity tests

    Time frame: On the day of surgery, before knee arthroscopy

    With the kinematic measurement device attached to the bones of the lower limbs, various knee laxity tests will be performed by a physician while the kinematics of the knee are recorded; correlations will be sought between the subjective evaluation of the physician and the kinematic data.
