Knee Injury

FAQ about the KneeKG™ System


Knee injury assessment with the KneeKG™ System takes about 30 minutes for one knee and 45 minutes for two knees.

A knee assessment with the KneeKG™ System requires two visits.

First Visit: 
During your first visit, your Knee Kinesiography will take place. The results will then be analyzed.

Second visit: 

During the second visit, a clinician will explain your knee injury assessment results and show you specific exercises based on your results.

If you wear orthotics, bring them with your shoes. Please also note that you should: 
  • Bring a pair of shorts and a pair of light socks;
  • Not apply any cream on your knee or your thigh on the day of the exam.
You will not be able to take the knee injury assessment if you:
  • Have a knee that blocks or has acute knee pain or acute swelling of the knee due to a recent trauma;
  • Or, if you cannot walk for 5 to 10 minutes on the treadmill at a comfortable pace without holding the handles due to:
    • An important balance problem;
    • A severe limp while walking;
    • The need to wear a brace, a cane or a walker to be able to walk;
    • Recent surgery or knee injection (cortisone, visco-supplementation, or platelet-rich plasma) that still cause severe pain or swelling.
If you think that you will not be able to take the test for any of these reasons or any other, simply notify the clinic.

Many health institutions provide knee injury assessment with KneeKG™. You can find a clinic offering the Knee Kinesiography through our website.

Healthcare Professionals:

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.


Patellofemoral               Syndrome

ACL injury

  • 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
  • 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
  • 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.
