What science says about Knee Kinesiography

Knee pain clinical assessment with KneeKG™

KneeKG™ commercialized by Emovi Inc is a regulatory cleared* knee pain clinical assessment tool used to conduct a Knee Kinesiography. This technology evaluates knee functional deficiencies linked to patients’ current symptoms or orthopaedic disease progression.

Obtaining a functional knee assessment is key to understanding the root cause of a patient’s symptoms.

X-rays and MRIs can inform clinicians about the structure of the joint. However, a patient’s pain is correlated with dynamic movement patterns, not static imaging1.

The KneeKG™ evaluates knee function by identifying biomechanical markers associated with pain, injury, and the risk for future orthopaedic impairments.

These markers are derived from the 3 dimensional (3D) kinematics of the knee and include flexion/extension, varus/valgus, internal/external tibial rotation.

The KneeKG™ is to the knee, what the EKG (electrocardiogram) is to the heart.

It provides objective information about knee joint function, and does not rely on a subjective interpretation of movement patterns. It allows the clinician to develop a patient-specific treatment plan to address the deficits identified from the KneeKG™ assessment.

Use of the KneeKG™ as part of a patient’s clinical care, produced statistically significant and clinically meaningful improvements that are superior to standard of care3

KneeKG™ clinical trials have demonstrated outcomes of :

  • Reduce pain
  • Improve function
  • Increase patient satisfaction (84%)4
  • Enhance adherence to treatment (88% after 3 months)3
  • Reduce biomechanical markers that are risk factors for osteoarthritis progression (varus-thrust)2

Represents a revolutionary clinical assessment platform

The KneeKG™ can play an integral role in the management of knee pain due to orthopedic conditions, including osteoarthritis, anterior knee pain, ligament injuries and others.

Proven treatment results have been demonstrated when incorporating the KneeKG™ as part of the clinical care pathway:

Knee Kinesiography

A Knee Kinesiography with KneeKG™, is a brief in-clinic exam that accurately and objectively assesses movement of the knee while the patient walks on a conventional treadmill. KneeKG™ is to the knee what the electrocardiogram is to the heart – demonstrating exactly how the joint is functioning.

The computerized assessment provides data about dynamic alignment and other mechanical deficits to help understand the patient’s knee pain and symptoms. The exam provides insight to the causes of knee symptoms in patients with knee osteo-arthritis, ligament injuries, anterior knee pain and other knee problems, including residual pain after joint surgery.

Use of the KneeKG™ has been proven to increase patient adherence and compliance with a prescribed treatment plan, and has improved patient and provider satisfaction with medical care. Additionally, by enabling a more efficient, personalized approach, it has led to patients’ reporting reduced pain and increased function3.

Knee Kinesiography can also be used with athletes to better understand mechanical deficits that can impact athletic performance level and allow the healthcare professional to develop appropriate exercise programs to minimize the risk for potential injuries.

    • Decrease absenteeism (initially 12 patients reported a mean of 20 work days missed vs a mean of 9 work days missed by 10 patients at follow up)
    • 7/11 surgical patients postponed their surgery

Founding Clinical Committee

Emovi is proud to present the four (4) founding members of its clinical comity, they have participated in numerous clinical studies demonstrating the value of the KneeKG™ system.

Guy Grimard, MD, FRCSC
Guy Grimard is an orthopedic surgeon. He obtained his Medical Degree from the University of Sherbrooke, in 1983 and went on to graduate in orthopedic surgery from the University of Montreal, in 1988. He completed his specialization in pediatric orthopedics at: CHU Sainte-Justine (in Montreal), the Royal Children’s Hospital (in Melbourne) and Hôpital Debrousse (in Lyon). He also completed his training in epidemiology and biostatistics at McGill University. He has been a clinical assistant professor, in the department of surgery and has been an orthopedic surgeon at CHU Sainte-Justine since 1994, as well as an active member of the Shriners Hospital, in Montreal. He was the Chief of the Orthopedics, at CHU Sainte-Justine from 2010 to 2014 and is an active member of the CHU Sainte-Justine Research Center. Dr. Grimard has also been a consultant in performance medicine, at Cirque du Soleil. He has served on the Executive Committee of the Quebec Orthopedic Association for 5 years. In addition he enjoys sports, having practiced ice hockey for over 30 years, and more recently becoming an avid cyclist.
