Résumé
Dataset Description Dataset Description This dataset is associated with the publication titled "A Distraction Knee-Brace and a Robotic Testbed for Tibiofemoral Load Reduction during Squatting" in IEEE Transactions on Medical Robotics and Bionics. It provides comprehensive data supporting the development and evaluation of a knee distraction brace designed to reduce tibiofemoral contact forces during flexion. Contents Cam Profiles STL files of the initial cam profiles designed based on averaged tibiofemoral contact force data collected from 5 squats of a patient with an instrumented prosthesis (K7L) from the CAMS Knee dataset (accessible via https://orthoload.com/). Optimized cam profiles, corrected based on experimental results, are also included. These profiles enable patient-specific adjustments to account for the non-linear evolution of tibiofemoral contact forces with flexion angles. Experimental Results CSV files containing raw results from robotic testbed experiments, testing the knee brace under various initial pneumatic pressures in the actuators. Data is provided for tests conducted: Without the brace, With the initial cam profiles, With the optimized cam profiles. Each CSV file corresponds to a specific test condition, detailing forces and kinematics observed during squatting. 3D Models of Bones and Testbed Components Geometries of the femur head and tibial plateau used in the robotic testbed experiments, provided in STEP, STL, and SLDPRT/SLDASM formats. A README file describes the biomechanical coordinate systems used for: Force and kinematic control of the robotic testbed, Result interpretation and visualization. How to Open and Read the Provided Files The dataset includes files in CSV, SLDPRT, SLDASM, STL, and IGES formats. Below are recommended software solutions, with a preference for open-source options: CSV (Comma-Separated Values): Can be opened with Microsoft Excel, Google Sheets, or open-source software like LibreOffice Calc or Python (using pandas). SLDPRT & SLDASM (SolidWorks Parts and Assemblies): These files are native to SolidWorks. For viewing without SolidWorks, use eDrawings Viewer (free) or FreeCAD (limited compatibility). STL (3D Model Format): Can be opened with MeshLab, FreeCAD, or Blender. Most 3D printing software (like Cura or PrusaSlicer) also support STL. IGES (3D CAD Exchange Format): Can be read with FreeCAD, Fusion 360 (free for personal use), or OpenCascade-based software like CAD Assistant. For full compatibility, commercial software like SolidWorks or CATIA may be required for SLDPRT and SLDASM files. However, FreeCAD and other open-source tools provide partial support. See the associated publication and the README files included in the dataset for more information.
