Novel Implant Designs In Magnetic Drug Targeting
… forces, have led researchers to study the use of implants to increase magnetic forces and the collection of MDCPs. This method is termed implant assisted (IA) - MDT, which exploits basic principles of high gradient magnetic separation to improve local drug retention.</p> <p>The work herein will …

Biomechanical Outcomes of Distinct TKA Surgical Alignments and Implant Designs
… alignment methods with an overall goal of implant longevity to ones that are more personalized to better replicate individual native knee kinematics. Personalizing TKA knee kinematics to better replicate a patient’s native knee kinematics has evolved in response to a reported 20% …

Development of a two-axis cyclic loading device for mechanical testing of glenoid component fixation
… of response forces acting on the glenoid implant is a desired outcome since it can be used to compare implant designs and allows for controlled testing of alternative materials for prosthesis advancement to lessen the stresses that produce the rocking horse phenomena.

Side-to-Side Comparison of Total Shoulder Arthroplasty and Intact Function in Individuals
… is to determine if patients with one of two TSA implant designs on one side achieve the same range of motion as their intact side, and if so to find if they compensate using increased scapula rotation over normal humeral motion. Six TSA subjects performed for each shoulder abduction, forward …

ASSESSMENT OF PERI-IMPLANT BONE MICROARCHITECTURE IN D4 BONE: AN EX VIVO MICROCT ANALYSIS
… study aimed to evaluate the impact of different implant designs on primary stability, peak insertion torque (PIT), implant stability quotient (ISQ), and peri-implant bone microarchitecture in low-density bone (D4). The investigation focused on three Straumann implant systems: Bone Level Tapered …

Validation and Analysis of Model-Predicted Patellar Implant-Synthetic Bone Relative Motion in Cementless Total Knee Replacement During a Single-Leg Lunge
… fixation, however, few cementless patellar implant micromotion tests have been developed. Previous studies were all focused on qualifying tibial micromotion, experimentally measuring relative motion between the tray and bone or computationally predicting micromotion at the tibial tray-bone …

Specimen-Specific Natural, Pathological, and Implanted Knee Mechanics Using Finite Element Modeling
… higher knee function in total knee replacement designs. As a result, clinicians and implant manufacturers are interested in improving patient outcomes, and evaluation of knee mechanics is essential for better diagnosis and repair of knee pathologies. Common knee pathologies include …

Design and Development Towards a Novel Prosthesis for Total Shoulder Arthroplasty to Reduce Aseptic Glenoid Loosening
… moment arms was observed. The novel glenoid designs were not found to alter the post-surgical kinematics. FE models of the biradial, compartmental and pear-shaped glenoid implant designs were subjected to compressive and shear loading according to the American Society for Testing and …

Reduced order modelling of bone resorption and formation.
… remodelling process should help to develop new implant designs which encourage rapid osteointegration. There are a number of limitations with respect to previous research in the field of mathematical modelling of the bone remodelling process, including the absence of an osteocyte loop of …
