CONTENTS ----------- The dataset contains the following files: METHODS_ADL motion inputs.zip - Motion input files for walking and the 7 activities of daily living (ADLs) which includes STOOP, SSL, SSN, XLG, PIVOT, ROLL and TIE which were directly fed into the geometric model - Column 1: Flexion(+)/extension(-) angle (degrees) - Column 2: Abduction(+)/adduction(-) angle (degrees) - Column 3: Internal(+)/external(-) rotation angle (degrees) RESULTS_DM neck-liner contact_Raw data.xlsx RESULTS_Impingement_Raw data.xlsx - Raw data output from the geometric model, which includes one impingement matrix for each combination of implant type (STD,DM, LL), implant size, and activity assessed. Each combination was assessed with a variety of cup inclination (30-70 degrees) and anteversion (0-50 degree) angles. Matrices are populated with numbers and corresponding colours (using conditional formatting) to visualise the type of impingement (if any) which occurred for each condition assessed. Possible outcomes include: implant-implant impingement (1, blue); bone-bone impingement (2, purple); implant-bone impingement (3, grey); or no impingement (4, white). - The "DM neck-liner contact" sheet relates to impingement (contact) between the femoral neck and mobile polyethylene liner of dual mobility cups. - The "Impingement" sheet relates to impingement between the femoral neck and liner (STD, LL) or metal liner insert (DM) at the component's maximum range of motion. RESULTS_DM neck-liner contact_Summary tables.xlsx RESULTS_Impingement_Summary tables.xlsx - Summary data matrices created using the outputs from the geometric model (one per component). Each matrix is populated with numbers that range from 0 to 7, which describe the frequency of impingement events which occurred across the 7 ADLs investigated (i.e., 0 = no impingement events during any of the ADLs; 7 = impingement occurred during every ADL). Each cell is also coloured using a red to green colourscale using conditional formatting. - The "DM neck-liner contact" sheet relates to impingement (contact) between the femoral neck and mobile polyethylene liner of dual mobility cups. - The "Impingement" sheet relates to impingement between the femoral neck and liner (STD, LL) or metal liner insert (DM) at the component's maximum range of motion. 4.
