This analysis determined whether the type and level of physical activity changes during the initial 24 months post-total hip (THR) or total knee replacement (TKR) compared to pre-operative levels, and how this change compares to people without arthroplasty or osteoarthritis. Data from a prospective cohort dataset (Osteoarthritis Initiative dataset) of community-dwelling individuals who had undergone a primary THR or TKR were identified. These were compared to people who had not undergone an arthroplasty and who did not have a diagnosis of hip or knee osteoarthritis during the follow-up period (control). Data were analysed comparing between-group and within-group differences for physical activity (gardening, domestic activities, sports, employment, walking) within the first 24 months post-arthroplasty.Introduction
