Piezoresistive UHMWPE WMCNT Sensors for Instrumented Total Knee Replacements
… developed and validate an instrumented total knee replacement using a novel piezoresistive polymeric sensor. The addition of multi-walled carbon nanotubes (MWCNT) as electrically conducting fillers to the ultra-high molecular weight polyethylene (UHMWPE) transforms the electrically …

Investigation of a heirarchical collagen scaffold/3D printed lattice structure designed for use in total knee replacements
… is a common cause of late-stage failure in total knee replacement (TKR) surgery. This multifactorial condition is exacerbated by stress shielding and micromotion at the bone/implant interface. Stress shielding can be reduced using implant materials with a similar modulus to that of the …

Research into the Design and Validation of an Innovative Intraoperative Load Sensor for Total Knee Replacements through Experimental and Cadaveric Investigations
Balancing the force between compartments in the knee joint during a Total Knee Replacement (TKR) is a vital parameter for surgeons to achieve successful outcomes for patients due to the complexity of the joint, articulating surfaces, tendons, and ligaments. These structures are all impacted by the …

Retrospective Chart Review of Patients Following Unilateral Total Knee Replacement to Assess Achievement of Functional Milestones Based on Type of Anesthetic Used Intra-Operatively
<p>PURPOSE: Given the large number of Total Knee Replacements (TKR) performed annually in the US and the prediction that those numbers will increase, providing optimal analgesia during TKR is an important strategy for reducing cost and improving patient outcomes. Currently, no standard analgesia …

Finite element analysis of total knee replacement considering gait cycle load and malalignment
… of gait cycle, malalignment and overweight on total knee replacements using a finite element method. Dynamic and finite element models of fixed- and mobile-bearing implants have been created and solved; the fixed- and mobile-bearing implants demonstrated different performance on movement and …

High flexion kinematics and kinetics for the improvement of artificial knee joints
Total knee arthroplasty has been effective in reducing pain, but less so in restoring function, especially for activities requiring deep knee flexion. The philosophy of this dissertation was that more functionally effective and optimally designed artificial knees could be created for high flexion …

Design of a Cyclic Sliding, Dynamically Loaded Wear Testing Device for the Evaluation of Total Knee Replacement Materials
… normal walking, the relative motion of the human knee involves flexion/extension, anterior/posterior sliding, and medial/lateral rotation. As well, the knee experiences a complex, dynamic loading curve with a peak of up to seven times body weight. However, most wear testing machines that have been …

Failure of Primary Total Knee Arthroplasty: Establishing a Baseline for Retrieval Analysis Using Well-Functioning Necropsy Specimens
<p><strong>Introduction</strong>. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or …
