Objective: We aimed to clarify the relationships between the International Classification of Functioning, Disability and Health (ICF) constructs of Activity and Participation in knee arthroplasty patients so that we could utilize them better in clinical practice to improve activity and participation.
Methods: Working with 118 elderly patients who underwent primary knee arthroplasty, we developed an evaluation to apply to body function, activity, participation, subjective health, and contextual factors. We used path analysis model construction preoperatively and six months post-operatively. We analyzed activity and participation using the ICF core sets for Osteoarthritis.
Results: Pre-operative path analysis showed significant structural pathways between muscular strength and activity, Timed Up and Go (TUG) test and activity, and activity and participation. In addition to the preoperative factor and knee pain and mental component summaries, we also evaluated mental component summaries and activity, gender and participation post-operatively.
Conclusion: The significant pathways suggest that treatments and interventions —such as joint arthroplasty—aimed at improving activity and participation for knee pain have both mental health and contextual factors.
