Motion capture dataset of 137 post-operative total hip replacement patients performing activities of daily living

This dataset comprises comprehensive motion capture and ground reaction force data from 137 post-operative total hip replacement (THR) patients. Data were collected between 2013 and 2015 using a 10-camera Vicon system and dual force plates during a range of activities of daily living (ADLs), including level walking, stair negotiation, sit-to-stand, lunge, and squat tasks. Marker trajectories and ground reaction forces were processed using standard biomechanical techniques and segmented into key movement events. The dataset has previously been used to identify biomechanical differences in THR patients by age, gender, BMI, and function, and to explore joint contact forces and their impact on bone loading. It is now released for wider use in musculoskeletal modelling, with potential application in AI and machine learning model development. This study was supported by the European Union's Seventh Framework Programme (FP7/2007-2013) under grant agreement no. GA-310477 LifeLongJoints. A small subset of this dataset (comprising a limited number of participants and trials) was previously made available under DOI 10.5518/319 as part of our previous publication. The current dataset represents the complete release, encompassing all participants and all recorded activities of daily living collected under the same methodological framework. The overlap is therefore limited to a few shared example files used for demonstration in the earlier publication.
