Triaxial Accelerometry Study

This study looks at how physical activity levels are in the long term after hip surgery. Arthritis can make everyday movement difficult, and hip replacement surgeries-such as total hip arthroplasty (THA) and hip resurfacing-help reduce pain and improve function. However, it is not clear how these surgeries affect long-term physical activity. To learn more, researchers are following up with patients who had one of these surgeries 15 years ago. Participants will wear two small activity-tracking devices (accelerometers): one on their wrist for 10 days and one on their thigh for 48 hours. These devices will measure how much and how intensely they move. Participants will also complete short physical activity questionnaires. By comparing activity levels between the two types of hip surgery, the study aims to understand their long-term effects on mobility and health. The results could help doctors improve treatment and recovery plans for future patients. All data will be kept private, and participation is voluntary.
