Hip Osteoarthritis, Physical Inactivity
Conditions
Brief summary
Rationale: THA is a widely applied procedure for osteoarthritis of the hip. After THA, one can expect an increase in physical activity due to the reduction of pain and increased range of motion of the hip joint, especially in young patients who in general have more active lifestyles. However, these young patients and their doctors don't know which increase in physical activity can be expected. Objective: To measure the difference in physical activity before and after THA. Study design: Longitudinal prospective single center observational study. Study population: 87 patients who have primary THA under the age of 50 years. Excluding patients with an underlying oncologic disease which results in THA. Intervention: N.a. Main study parameters/endpoints: The first primary endpoint is physical activity in minutes per day. The other primary endpoint is MVPA in minutes per day. Secondary endpoints are difference of TUG outcomes in seconds and the difference of 6MWT outcomes in meters. For the patients experience, the COPM total scores and NRS pain scores will be measured. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: This study requires three outpatient clinic visits. These visits will coincide with regular outpatient clinic visits, so patients will not have to come in extra for this study. During the preoperative and 1 year postoperative visit, the patients will complete the COPM. The patient will wear a PA monitor for 7 days after each visit. Patients might experience confronting feelings while being exposed to their PA activity profile after the study or experience mild discomfort while wearing the PA monitor since it will be worn 24 hours per day for 7 days. Also, filling in the questionnaires will take some time (5-10 minutes per questionnaire series). There are no significant physical risks associated to this study.
