Knee Osteoarthritis: An Investigation into the Clinical Practice of Physiotherapists in Canada

The purpose of this study was to establish the clinical practice of physiotherapists who treat people with knee osteoarthritis (OA) in Canada and examine their knowledge, awareness, use of, and attitudes toward clinical practice guidelines (CPGs). We conducted a cross-sectional survey of physiotherapists who are licensed to practise in Canada and who treat people with knee OA. A total of 388 physiotherapists completed our survey. Approximately two-thirds of them (271) were aware of CPGs. Out of all CPG recommendations, most respondents provided leg strengthening exercises (380) and education (364). More than 80% believed that CPGs improved patient care and enhanced decision making and were confident in their ability to interpret CPGs. More physiotherapists (204) identified barriers to the use of CPGs than facilitators of their use (117). Physiotherapists who were employed in private practice were substantially more likely to use interventions such as acupuncture (odds ratio [OR] 5.98; 95% CI: 2.92, 12.23; p < 0.01) and joint mobilization and manipulation (OR 6.58; 95% CI: 3.45, 12.55; p < 0.01) than were physiotherapists employed in hospital settings. Two-thirds of respondents were aware of CPGs. Physiotherapists provided education and leg strengthening exercises more often than aerobic exercise and weight management advice. Physiotherapists employed in private practice were more likely to use adjunct interventions.
