Abstract

Aim: To measure the level of adherence of patients with primary knee osteoarthritis (KOA) to an interventional therapeutic and rehabilitation programme and investigate factors that hinder patients' adherence.

Methods: A total of 154 participants with primary knee osteoarthritis (KOA) were divided into intervention and control groups. The intervention protocol included patient education on the nature and treatment of KOA, therapeutic exercise, a weight loss programme for overweight patients, and a physical therapy programme. Participants were followed for 3 months. The Visual Analog Scale for Pain (VAS-p), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and knee Kellgren-Lawrence OA grading were measured before and after the intervention. Additionally, the Morisky adherence questionnaire and the WHO Multidimensional Framework for factors affecting adherence were assessed.

Results: One fifty four participants with KOA were randomly allocated into intervention and control groups. A low level of adherence was detected in both groups (68.8% in the intervention group vs. 84.4% in the control group). Patients who followed the interventional programme were more adherent. Adherence to therapy was associated with a reduction in the Visual Analog Scale for Pain (VAS-p) (p = 0.016) and improved function as measured by WOMAC (p = 0.018). Factors primarily associated with patient non-adherence included unemployment (67.8%), low income (59.3%), no previous response to therapy (58.5%), less frequent follow-up visits (55.1%), lack of insurance (66.9%), difficult access to services (59.3%), and high cost of services (55.1%).

Conclusion: Adherence to treatment in OA patients is a significant concern and a common problem, appearing to be associated more with socioeconomic factors than with pain and function.
