3D technology that could revolutionize the treatment of knee osteoarthritis

A new technology called knee kinesiography is changing the way doctors treat osteoarthritis of the knee. This form of osteoarthritis affects about four million Canadians, or 13.6% of the population, according to the Public Health Agency of Canada.

Osteoarthritis of the knee is more common in people over 60, but it also affects a significant proportion of younger people, even those in their forties. For reasons still unknown, women are more likely to develop osteoarthritis than men.

In , the protective cartilage of the joint is depleted over time and can cause bone friction on the bone. The disease is associated with aging, but can also be caused by injury or other forms of physical stress on cartilage.

Anatomical abnormalities and other inherited factors can also cause mechanical knee dysfunction. This can cause a misaligned knee joint, increasing stress on the cartilage. It is critical that physicians understand the dysfunction well to correct it.

Our research in biomechanics, , radiology, epidemiology, physiotherapy and data science led us to develop and evaluate the clinical utility of a new technology called knee kinesiography, which is used to treat patients with osteoarthritis in Quebec.

Currently, doctors diagnose osteoarthritis of the knee by examination and X-rays and assess mechanical dysfunction through a questionnaire and a clinical observation of the knee.

But the questionnaires are subjective and the observations are not quantified. The clinician observes the leg with the , but does not take action. This makes it difficult for the doctor to assess exactly what is happening, determine when the problems started, and identify what is causing the joint stress and its deterioration.

Knee movements in 3D

Healthcare professionals can offer patients treatment to relieve pain, as well as physical therapy exercises. But to correct knee dysfunctions, they need to be able to target dysfunctions that are not visible to the naked eye.

Kinesiography of the knee, which was marketed in 2011 after 15 years of research, could change the game. The electrocardiogram is for the heart the knee. It is performed using a harness attached to specific areas of the leg to analyze the knee while moving.

This technology was developed by researchers from the École de technologie supérieure, the Research Center of the Center Hospital de l’Université de Montréal (CHUM) and the Université TÉLUQ.

Because this technology measures three-dimensional knee movement in real time, as well as rotations that are not visible to the naked eye, it allows healthcare professionals to assess the joint accurately and accurately. By providing motion analysis that detects deviations from what is considered normal movement, the technology allows healthcare professionals to understand the source of cartilage stress.

Bruny Surin talks about his experience with knee kinesiography to treat osteoarthritis.

Laurent Duvernay-Tardif, a physician and athlete, explains how knee kinesiography can help heal and prevent knee injuries.

Personalized attention

Using this technology, professionals can offer personalized treatment from the source of the problem, such as neuromuscular exercises that can be done at home or under the supervision of a physiotherapist or kinesiologist.

According to the results of our clinical study, conducted with 515 patients, this technology is promising. Patients who received knee kinesiography and an individualized care plan were able to correct several measured biomechanical dysfunctions. Almost nine out of 10 (88 percent) of those who participated in the they reported doing their exercises for at least three months, which showed that they were committed to their treatment. Adherence to exercise is an important topic in studies that analyze the effect of an exercise program.

In addition, the researchers observed more improvement in the functional status of the knee for these patients, compared to the control group. These patients reported less pain and symptoms and felt more able to perform their daily activities. In addition, they reported greater satisfaction with their care and better results in functional testing.

Knee kinesiography is now offered in more than 100 clinics and hospitals in eight countries and is available in private clinics in Quebec. Studies are being carried out to assess the impact of this tool on private costs and public health services, with the aim of offering it to the public system (hospitals and clinics).

In addition to offering hope to thousands of suffering patients from , this innovation demonstrates, once again, that Quebec engineering fully deserves the praise it has earned.
