Plain English Summary

Background and study aims
Osteoarthritis (OA), the most common type of arthritis, is an incurable, long term condition that causes joints such as the knee to become painful and stiff. Maintaining a healthy weight and regularly exercising can help people manage their symptoms, but OA of the knee can often result in disability and make it hard for people to carry out their normal daily activities. Current medical practice (CMP) in treating OA of the knee is inconsistent and often involves GPs prescribing pain medication for patients waiting for total joint replacement. This treatment method is not very cost effective and can lead to the patient visiting their GP numerous times. Recently, a number of scientists and stakeholders within the Canadian healthcare system partnered with a company called Emovi Inc to develop a care programme for people with OA of the knee. The programme,, is a personalised treatment plan which includes the creation of a detailed structure and function (biomechanical) report of a patient’s knee using a knee kinematic graphic test (KneeKG). The programme also recommends various treatment interventions for each patient to help reduce the risk of their OA knee becoming worse. The aim of this study is to see whether the programme is effective in improving patient quality of life and joint mobility compared to CMP or CMP and KneeKG alone. Also, an analysis will be conducted to see which care approach is the most cost effective.

Who can participate?
Adults diagnosed with OA of the knee.

What does the study involve?
Participating GP clinics are randomly allocated to deliver one of three care management plans to their patients. Group 1 (control group) GP clinics give their patients CMP. Group 2 (intervention group) GP clinics give their patients CMP and a KneeKG exam. Group 3 (intervention group) GP clinics give their patients CMP, a KneeKG exam and the Mon Arthrose care programme (the complete care plan). Participants complete questionnaires and attend clinical assessments before treatment, and then again at 6, 12 and 24 months for follow up.

What are the possible benefits and risks of participating?
There is virtually no risk associated with the equipment and movements to be performed during the KneeKG analysis and the test is noninvasive and painless. Some discomfort may be felt when wearing the harness and in some rare cases, redness may appear. These usually disappear within hours after the examination. The risk of falling during treadmill walking is minimal. For safety reasons during the examination, a switchblade connected to a rope attached to the treadmill is attached to participant's clothing with a clip. If the clip comes off, the treadmill will stop automatically. There is a risk associated with having X-rays. Even if this exposure is low participants will be made aware of it. During the experiment, X-rays will be limited to one for each knee, so a total of two X-rays. Furthermore, the procedure is limited to the observation of the knee joint and therefore only the lower body region will be X-rayed in order to minimise exposure.

Where is the study run from?
1. University of Montreal Hospital Research Centre (Centre de Recherche du Centre Hospitalier de l'Université de Montréal (CRCHUM)) (Canada)
2. 75 participating GP clinics in Montreal and surrounding suburbs (Canada)

When is the study starting and how long is it expected to run for?
October 2014 to September 2018

Who is funding the study?
1. Minstery of Finance - Partnership Fund for an Innovative and Healthy Quebec (Fonds de Partenariat pour un Québec Innovant et en Santé) (Canada)
2. Emovi Inc. (Canada)
3. Sanofi (Canada)

Study information

Scientific title

Better diagnosis and treatment of knee osteoarthritis: a clinical and economic imperative for our health system


Study hypothesis

The main objectives of this project are to evaluate the effectiveness of Knee Kinematics graphics (KneeKG) and Mon Arthrose program in the treatment of osteoarthritis (OA) of the knee and get socio-economic data to compare the socio-economic impact of the technology and Mon Arthrose program compared to current medical practice (CMP).
Underlying assumptions:
1. We expect that the effectiveness of KneeKG technology with or without Mon Arthrose program will be superior to that of the CMP in 1st line care for the treatment of OA of the knee.
2. We also expect a reduction in direct and indirect costs of 20%, an improvement in the condition of more than 10% of the patient and a difference of knee kinematic parameters between the three health care approaches.

Osteoarthritis (OA) of the knee


Three types of care management will be compared:
1. CMP from General Practitioner (GP)
2. CMP alongside a KneeKG exam with treatment recommendations based on knee biomechanics
3. CMP alongside a KneeKG exam and a structured care program called Mon Arthrose (3 visits at an Mon Arthrose center, patient training of their condition and follow-up of home based exercises by a kinesiologist)

Drug names

Primary outcome measures

Phase 1: difference between the three groups at 6 months (0 to 6 months) of the variation of the overall score Knee Osteoarthritis Outcome Score (KOOS5) including 5 dimensions
Phase 2: difference in direct and indirect costs for the three therapeutic models at 6, 12 and 24 months

Secondary outcome measures

Phase 1: difference in joint biomechanics, as measured by KneeKG, between the three groups at 6 months, as defined by the normal to abnormal passage of at least one biomechanical risk factors from the following.
Improved absolute different biomechanical factors.
Comparison of overall score of Knee Osteoarthritis Outcome Score (KOOS5), to 12 months between the three therapeutic models (1- GP group, 2- GP group and KneeKG, 3- GP group with KneeKG and My Osteoarthritis program)
Phase 2: difference at 6, 12 and 24 months in quality of life, knee function, pain and global impression of change
