The results of a wide-ranging clinical study aimed at assessing the effectiveness of knee kinesiography, a new diagnostic tool developed in Québec, were made public today at the Centre de recherche du CHUM (CHUM Research Centre). The team of scientists, headed by Nicola Hagemeister, a Professor in the Systems Engineering Department at ÉTS and Researcher at CHUM, demonstrated the relevance of having general practitioners incorporate this new medical examination into their practice, especially when assessing biomechanical risk factors linked to the progression of osteoarthrosis.

Knee kinesiography, which has been described as an “electrocardiogram for the knee”, will make it easier for family doctors to detect anomalies associated with osteoarthrosis and knee injuries, and to adapt the treatment to each specific patient.


How does knee kinesiography work?

The system is designed to eliminate artifacts caused by the movement of the skin and muscles. It is positioned on the patient’s lower limb.

Through the use of an optical system, the 3D movement of the knee is captured as the patient walks on a treadmill at a comfortable, dynamic and controlled pace. Data pertaining to the three planes of movement are collected.

  • The results are immediate;
  • The patient is offered an explanation with a visual;
  •  Exercises aimed at correcting biomechanical deficiencies are recommended.

A technology that will improve the quality of life for thousands of people

Osteoarthrosis is the most common type of arthritis, affecting one out of every ten adults in Canada. In the case of osteoarthrosis of the knee, hundreds of thousands of Canadians can now benefit from this new diagnostic tool and significantly improve their quality of life.

Testimonial from Bruny Surin 

Renowned Olympic champion Bruny Surin suffers from osteoarthrosis of the knee. He has had an opportunity to undergo knee kinesiography. He speaks eloquently of the effectiveness of this tool!

Key figures 

  • 450 patients took part in the study and two thirds of the participants were women. The average age of the participants was 63. The patients had experienced symptoms of knee osteoarthritis for an average of six years.

  • 300 family doctors were involved in recruiting the participants. 

  • For the 3rd group of patients (appointment with the doctor + knee kinesiography test + training), no more than three supervised physical therapy exercise sessions were needed for the patient to feel less pain and be more mobile.

  • The two groups that received the knee kinesiography test (groups 2 and 3) stuck closely to their home exercise routines. 

  • 9 out of 10 doctors stated that the knee kinesiography test was useful in their practice.
