Knee Injury Assessment
FAQ for Clinicians

FAQ about the KneeKG™ System

Knee misalignment is recognized in clinical practice guidelines to influence disease progression and patient symptoms. However, human visual perception is influenced by the assessment environment. An optical illusion, patient physiognomies, and other factors also influence the perception of misalignment by clinicians.

The results of a knee injury assessment with the KneeKG™ system offers objective, quantifiable, actionable information about knee function for designing an efficient care pathway. It identifies mechanical deficiencies known to be a key factor in the development and progression of knee pathologies and those caused by specific injuries or complications.

Knee Kinesiography is done to assess:

  • The impact of an injury on the knee joint function;
  • Functional etiology of patient symptoms;
  • Mechanical biomarkers linked with the development and progression of knee pathologies;
  • The impact of treatments/surgery on the knee joint function.

Therefore, the healthcare provider can rapidly:

  • Gain an understanding of the symptoms and how to manage the problem efficiently with objective data; this compared to visual and manual exams, with static information from medical imaging techniques;
  • Work toward full, functional recovery rather than simply treating the pain.

The KneeKG™ System assesses 3D knee kinematics (3-dimensional knee movements) in dynamic and weight-bearing conditions. More specifically, KneeKG™ identifies and measures biomechanical markers related to the progression and symptoms of various knee pathologies and/or trauma.

These markers are extracted from the raw KneeKG™ measurements, which are the 3D kinematics of the knee and include:

  • Flexion/Extension;
  • Varus/Valgus;
  • Internal/External tibial rotation.

The KneeKG™ algorithms then analyze the data automatically and extract evidence-based Mechanical Biomarkers known to be linked with the progression of specific knee pathologies and pain symptoms or reported pain symptoms.

This medical resource provides instant reports with interpretations to help healthcare providers to personalize a treatment plan.

Evidence-Based Biomechanical Markers Provided by the KneeKG™ system.


Dynamic flexion contracture

  • Increases joint TF & PF loads
  • Leads to anterior knee pain
  • Increases tension & loads on quads
  • Reduces endurance

Varus/valgus thrust

  • Increases odds ratio OA progression by 3-4x

Varus/valgus alignment

  • Increases TF loads

Internal tibial rotation offset

  • Shifts load-bearing regions

Patellofemoral Syndrome

Dynamic flexion contacture

  • Increases PF stress

Varus/valgus alignment

  • Alters patellar tracking

Valgus collapse

  • Increses Q angle
  • Lateralizez the patella

Rapid internal tibial rotation

  • Increases PF shear stress

ACL injury

Dynamic flexion contracture

  • Compensation strategy to stabilize knee
  • Increases PF stress

Shift towards internal tibial rotation

  • Shifts TF load-bearing regions
  • Increases risk of OA

Variability in internal/external tibial rotation

  • Sign of instability

Varus thrust

  • Potential posterolateral instability

A knee injury assessment with the KneeKG™ System is performed by clinic staff trained and certified by EMOVI. This may be a physiotherapist, a kinesiologist, a physical/rehabilitation therapist or a health technician, depending on the clinic.

There are over 100 publications on KneeKG™ and the Knee Kinesiography with the KneeKG™ System. The literature and additional medical information is available for your review on our website or please contact an Emovi team member.

An installation call will be made with you to organize the installation and training of your staff. Contact us to discuss with one of our staff members.
