Why do this research?

Reason For Research

In Canada, about 700,000 youth hurt their knee every year while playing sports. Half of them go on to develop knee osteoarthritis (OA) by the age of 40. The risk for knee osteoarthritis is greater for those that develop knee muscle weakness, or become physically inactive, and gain weight after their knee injury. Despite knowing this, the treatment of knee injuries tends to focus on returning to playing sports, with little effort spent on osteoarthritis prevention. With a team of patients and healthcare providers, we developed a new digital (online) education and exercise-based program to help boost recovery from a knee injury and reduce the risk for osteoarthritis. The SOAR or – Stop OsteoARthritis program aims to improve user’s ability to self-manage their knee health through education, personalized exercise, activity tracking, and weekly action planning. This research is a key step forward in changing how we treat knee injuries in Canada.

Methodology

Execution of Research

The second step in testing the SOAR program was to assess if the program could improve health outcomes reported to be important to participants at increased risk of knee osteoarthritis after a sport-related knee injury. This included things like knee muscle strength, physical activity, self-management of knee health, self-efficacy, quality of life, and kinesiophobia (fear of pain or injury due to movement). We recruited 54 people aged 16-35 who had experienced a sport-related knee injury anywhere between 1-4 years ago. Participants were split randomly into two groups. One group received a 9-week SOAR program right away, while the other group received a 9-week SOAR program after a 9-week wait.

As a part of this trial, we also looked at how social support affects people’s participation in exercise therapy by conducting interviews with 15 participants.

Two patient partners with lived experience of knee trauma and three physiotherapists helped with the study procedures.

The SOAR program included:

    1. A 2-hour Knee Camp where participants attended a virtual group education session, one-on-one knee exam and one-on-one exercise therapy and physical activity goal setting guided by a physiotherapist.
    2. Weekly personalized exercise and activity program built from participants goals to do at home alongside activity tracking (Fitbit) and an exercise log.
    3. Weekly one-on-one physiotherapist-guided counselling sessions to modify and add exercise-therapy and physical activity goals, and problem solve around any barriers participants might be experiencing.

Findings & Next Steps

We had 49 out of 54 people complete the study (91% of the original group we recruited). On average, the participants were 27 years old and had been dealing with their knee injuries for about 2.4 years.

The majority of participants completed the required study tasks, and physiotherapists rated participants’ commitment to the program as very high. During the 9-week treatment period, participants completed most of their exercise therapy (92%) and physical activity goals (84%). Despite high adherence, the SOAR Program did not result in meaningful improvements to knee strength, knee-related quality of life and self-efficacy, or physical activity levels in this highly active sample of participants. However, we did find that people who went through the program felt they were better at managing their knee health on their own and had greater improvements in kinesiophobia compared to those who had not completed the program. The program was also safe.

The interviews revealed three key themes related to the role of social support in fostering exercise participation. Themes included:

  • the importance of treating participants as a whole person, not just focusing on their physical needs
  • the value of a collaborative partnership between a clinician (physiotherapist) and participant, and
  • the need for ongoing support

The interview findings suggest that tailored social support strategies can enhance exercise adherence and long-term management of knee health after injury and have implications for improving physiotherapist-patient interactions.

This study has helped researchers develop the next study in the SOAR research program, which is a full-scale clinical trial to assess whether the SOAR program can prevent post-traumatic osteoarthritis (symptoms and magnetic resonance imaging
changes) after an Anterior Cruciate Ligament (ACL) tear. You can read more about SOAR 3.0 here.

If you have experienced an Anterior Cruciate Ligament (ACL) tear and had reconstruction surgery, and are interested in participating in this clinical trial please reach out to the SOAR team and check to see if you are eligible here.
