Osteoarthritis is one of the leading causes of disability. Total knee arthroplasty (TKA) is a surgical intervention for patients with severe osteoarthritis. Post TKA rehabilitation is crucial for improving patient’s quality of life. However, traditional rehabilitation has only focused on physical function; a systemic analysis of other dimensions such as social participation and environmental factors of post TKA rehabilitation is lacking. The aim of this study was to develop a core set from the International Classification of Functioning, Disability and Health (ICF) to create a comprehensive rehabilitation program for patients with osteoarthritis post TKA. Before the Delphi-based consensus process, a literature review process was performed for related ICF categories selection. We used a three-round Delphi-based consensus among 20 physical therapists with orthopedic rehabilitation expertise in a university-based hospital. A five-point Likert scale was used to rate the importance of each item. The consensus of ratings was analyzed using Spearman’s rho and semi-interquartile range indices. The ICF core set for post TKA rehabilitation was determined based on a high level of consensus and a mean score of ≥4.0 in the third Delphi-based consensus round. The ICF core set comprised 32 categories, with 13 regarding body function, four regarding body structures, nine regarding activities and participation, four regarding environmental factors, and two regarding personal factors. Our ICF core set for post TKA rehabilitation can provide information on effective rehabilitation strategies and goal setting for patients post TKA. However, further validation and feasibility assessments are warranted.
