In vivo knee biomechanics and implications for total knee arthroplasty implant design
… determine the limitations of contemporary Total Knee Arthroplasty (TKA) and to identify areas for future improvements. In line with this objective, the first goal was to quantify the ability of current TKA systems to restore normal knee kinematics and anatomy. Recently, proposals for gender …

Hip and Knee Biomechanics for Transtibial Amputees in Gait, Cycling, and Elliptical Training
… are at increased risk of contralateral hip and knee joint osteoarthritis, likely due to abnormal biomechanics. Biomechanical challenges exist for transtibial amputees in gait and cycling; particularly, asymmetry in ground/pedal reaction forces and joint kinetics is well documented and …

Effects of Increased Shoe Collar Height and Limb Dominance on Landing Knee Biomechanics in Collegiate Volleyball Players
… has been associated with increased frontal plane knee motion. Volleyball players wear mid-cut shoes (MC) that have an increased collar height rising slightly superior to the talocrural joint and malleoli. The purpose of this study was to determine the effect of MC and limb dominance on knee …

The effect of the Apos Therapy system on knee biomechanics in recreational athletes at risk of a non-contact anterior cruciate ligament injury
… of an unstable device (AposTherapy system) on knee biomechanics and muscular recruitment patterns while performing functional tasks. To accomplish the research, four separate trials were conductedseparatly.Firstly, a repeatability trial with 11 healthy physically active (male and …

Evaluation of movement variability and knee biomechanics during functional sporting tasks in healthy individuals and individuals following Anterior Cruciate Ligament Injury (ACL) and ACL reconstruction
… which can occur during some sporting activities. Knee biomechanics and movement variability (MV) comprise two very important aspects relating to injury risk, where it has been suggested that the latter may play a role in ACL injury. AimThe aims of this thesis were: to investigate MV and knee …

DESIGN AND DEVELOPMENT OF BIOFIDELIC SIMULATION TRAINERS FOR PEDIATRIC KNEE EFFUSION ASSESSMENT
This research aimed to improve pediatric knee injury diagnosis as indicated by effusion by developing a systematic process for designing and validating biofidelic training models using small-scale manufacturing techniques. The problem addressed was clinicians' lack of exposure to pediatric …

The effect of change of direction angle on kneeand hip biomechanics : implications foranterior cruciate ligament injury
… frequently occur without contact. Changes in the knee valgus (abduction) angle and knee valgus (external abduction) moment and limb asymmetry have been linked to greater risk of ACLinjury. Change of direction (COD) manoeuvres are important for many field sports, however they are unfortunately …

Design and evaluation of a biomimetic agonist-antagonist active knee prosthesis
… and evaluation of a novel biomimetic active knee prosthesis capable of emulating intact knee biomechanics during level-ground walking. The knee design is motivated by a mono-articular prosthetic knee model comprised of a variable damper and two series elastic clutch units spanning the knee …

The use of series compliance and variable transmission elements in the design of a powered knee prosthesis
Compared to non-amputees, above knee amputees expend significantly more metabolic energy. This is a result of the passive nature of most knee prostheses, as the development of clinically successful powered knee prostheses has remained a challenge. The addition of powered elements, such as electric …

A Study Exploring the Use of Artificial Ligaments to Enhance the Human-Robot Interface Via Force Distribution Manipulation in Biomimetic Cuff Systems
… that provide aid to patients with an injured knee. In addition, there has been an effort to incorporate cable-driven designs rather than rigid attachments. This change in design decreases the overall weight of the system and can allow the cable to adapt to a user’s change in gait patterns. …

Inverse Dynamic Analysis of ACL Reconstructed Knee Joint Biomechanics During Gait and Cycling Using OpenSim
… (anterior cruciate ligament) injuries of the knee joint alter biomechanics and may cause abnormal loading conditions that place patients at a higher risk of developing osteoarthritis (OA). There are multiple types of ACL reconstruction (ACLR), but all types aim to restore anterior tibial …

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 …

Quadriceps Avoidance Characteristics of Persons with a Reconstructed Anterior Cruciate Ligament during a Forward Lunge
… the use of the quadriceps is avoided and greater knee flexion is demonstrated during gait. Quadriceps avoidance is considered to be an abnormal movement pattern that can have negative effects after ACL reconstruction especially when it is adopted for a long time. While quadriceps avoidance has …
