Повний текст джерелаENGLISH ABSTRACT: The knee is the largest, most complicated and incongruent joint in the human body. It sustains very high forces and is susceptible to injury and disease. Osteoarthritis is a common disease prevalent among the elderly and causes softening or degradation of the cartilage and subcondral bone in the joint, which leads to a loss of function and pain. This problem can be alleviated through a surgical intervention commonly termed a “knee replacement”. The aim of a knee replacement procedure is to relieve pain and restore normal function. Ideally, the knee replacement prosthesis should have an articulating geometry similar to that of the patient’s healthy knee, and must allow for normal motion. Unfortunately, this is often problematic since knee prostheses are supplied in standard sizes from a variety of manufacturers and each one has a slightly different design. Furthermore, commercial prostheses are not always able to restore the complex geometry of an individual patient’s original articulating surfaces. This dissertation shows that there is a significant variation between knee geometries, regardless of gender and race. This research aims to resolve the problem in two parts: Firstly by presenting a method for preoperatively selecting the optimal knee prosthesis type and size for a specific patient, and secondly by presenting a design procedure for designing and manufacturing patient-specific unicompartmental knee replacements. The design procedure uses mathematical modelling and an artificial neural network to estimate the original and healthy articulating surfaces of a patient’s knee. The models are combined with medical images from the patient to create a knee prosthesis that is patient-specific. These patient-specific implants are then compared to conventional implants with respect to contact stresses and kinematics. The dissertation concludes that patient-specific implants can have characteristics that are comparable to or better than conventional prostheses. The unique design methodology presented in this dissertation introduces a significant advancement in knee replacement technology, with the potential to dramatically improve clinical outcomes of knee replacement surgery.
AFRIKAANSE OPSOMMING: Die knie is die grootste, mees komplekse en mees ongelyksoortige gewrig in die liggaam. Osteoarthritis is ’n siekte wat algemeen by bejaardes voorkom en die versagting of agteruitgang van die kraakbeen en subchondrale bene in die gewrig tot gevolg het, wat tot ’n verlies van funksionering en pyn lei. Hierdie probleem kan verlig word deur ’n chirurgiese ingryping wat algemeen as ’n “knievervanging” bekend staan. Die doel van ’n knievervangingsprosedure is om pyn te verlig en normale funksionering te herstel. Ideaal gesproke behoort die knievervangingsprostese ’n gewrigsgeometrie te hê wat soortgelyk aan die pasiënt se gesonde knie is, en normale beweging moontlik maak. Ongelukkig is dit dikwels problematies aangesien knieprosteses in standaardgroottes en deur ’n verskeidenheid vervaardigers verskaf word, wat elkeen se ontwerp effens anders maak. Verder kan kommersiële prosteses nie altyd die komplekse geometrie van ’n individuele pasiënt se oorspronklike gewrigsoppervlakke vervang nie. Hierdie proefskrif wys dat daar ’n betekenisvolle variasie tussen knieafmetings is, afgesien van geslag en ras. Hierdie navorsing is daarop gemik om die problem op tweërlei wyse te benader: Eerstens deur ’n metode aan te bied om die optimal knieprostesetipe en -grootte vir ’n spesifieke pasiënt voor die operasie uit te soek, en tweedens om ’n ontwerpprosedure aan te bied vir die ontwerp en vervaardiging van pasiëntspesifieke unikompartementele knievervangings. Die ontwerpprosedure gebruik wiskundige modellering en ’n kunsmatige neurale netwerk om die oorspronklike en gesonde gewrigsoppervlakke van ’n pasiënt se knie te bepaal. Die modelle word met mediese beelde van die pasiënt gekombineer om ’n knieprostese te skep wat pasiëntspesifiek is. Hierdie pasiëntspesifieke inplantings word dan met konvensionele inplantings vergelyk wat kontakstres en kinematika betref. Daar word tot die slotsom gekom dat die pasiëntspesifieke inplantings oor eienskappe kan beskik wat vergelykbaar is met of selfs beter is as dié van konvensionele prosteses. Die unieke ontwerpmetodologie wat in hierdie proefskrif aangebied word, stel beduidende vordering in knievervangingstegnologie bekend, met die potensiaal om die kliniese uitkomste van knievervangingsoperasies dramaties te verbeter.

The hinge joint is movable joints in the human leg connecting the elbow, knee, ankle, finger and toe joints. Among hinge joints, Tibiofemoral (TF) joint has complex joint structure with six degrees of freedom. Thus, it is important to analyzed tibiofemoral joint throughly in order to understand other moving joint of human being. The exo-prosthesis of the knee depends only on the femoral polode. Conversely, the endo-prosthesis of the knee relies upon the TF condylar surface and the slip ratio variation, without needing to consider the femoral polode. However, femoral polode is difficult to understand if the contact joint surface and slip are described by moving polode of linkage mechanism. Conversely, the contact joint surface and slip cannot be described if the femoral polode is described by moving polode of linkage mechanism. Therefore, the endo-prosthesis design can be more suitable for human but it is difficult to achieve if the contact joint surface cannot be correspond with femoral polode. There are many difficulties to achieve these goals. Firstly, the joint structure includes femoral polode and femoral condylar radius, etc. Therefore, it is too complicated to describe the anterior/posterior cruciate ligament for mechanical analysis. Moreover, the different cycles of flexion-extension and body weight can be produced by gait cycle. Therefore, the purpose of this study is to explore the planar kinematic and kinetic mechanism so that the joint surface can be correspond with femoral polode. The objective functions include the line shape of the joint surface, femoral polode and slip and factors, the length of bar, the anterior/posterior cruciate ligament and gait, etc. the main objective of this study is to assistance the people with some knee disease such as osteoarthritis or joint surface repair techniques. Finally, that tibiofemoral joint analysis is as a basic foundation, we also explored the correlation between the tibiofemoral joint and the finger joint. Firstly, the finger joint design method is similar to tibiofemoral joint. Moreover, to support people with osteoarthritis. In addition, the pain of osteoarthritis is sometime from stress abrasion of tibiofemoral joint. Therefore, the sensitivity analysis of factors such as Hertz contact stress is also discussed to understand the main influencing factors and the gait location of maximum Hertz contact stress.

In this study, a wearable robotic device is designed in an attempt to apply adequate forces to swing the wearer’s legs for walking assistance. Thus, the swing motions of the device and the user must be synchronized to provide assist forces. The device has two active joints located around the hips of the user, and each joint is actuated by using a brushless DC motor and a ball-screw. Besides, two sets of force measuring module are mounted on the device to perceive the interaction forces between the device and the user. Then, two neural oscillators take the signals of interaction forces as sensory feedbacks to generate anti-phase rhythmic signals for driving the two active joints. Experimental results show that the movements of the active joints are actually synchronized with that of user’s legs, and the device is helpful for walking assistance. However, the weight of the device need to be further reduced before it can be used to help those people who walks with difficulty.

Повний текст джерелаTi6Al4V alloy is the leading material for hip replacement because of its biocompatibility, elastic modulus and good yield strength, but shows poor corrosion and wear properties in simulated body fluid. Thin coatings were fabricated on Ti6Al4V alloy using Zirconium, Niobium and Titanium reinforcements with the aid of Nd:YAG Rofin Sinar laser system. Niobium reinforcement produced the best coating that displayed the best corrosion resistance and percentage increase in wear resistance in simulated body fluid as compared to the substrate. Therefore, this coating will perform best as orthopaedic implant material.
