  1. 1. Total knee arthroplasty : aspects on improved fixation in the younger patient

    Författare :Anders Henricson; Kjell G Nilsson; Tore Dalén; Sören Toksvig-Larsen; Umeå universitet; []
    Nyckelord :Surgery; Total knee arthroplasty; total knee replacement; mobile bearing; trabecular metal; hydroxy-apatite coating; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : The results of total knee arthroplasty are inferior in younger patients. The challenge today is therefore to develop designs and concepts that will last at least 25 years. This thesis has evaluated the fixation to bone of modern designs of knee prostheses uring RSA analysis. LÄS MER

  4. 3. Total knee arthroplasty : Alternative aspects on fixation, design and postoperative treatment

    Författare :Gunnar Adalberth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Total knee arthroplasty; RSA; migration; all-polyethylene; drainage; cement; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Total knee arthroplasty as a treatment of severe gonarthrosis has become a great success, but tibial component loosening is still a major reason for failure. When total knee arthroplasty was introduced, only all-polyethylene (AP) tibial components were available. LÄS MER

  5. 4. Sensory Aspects of Knee Injuries

    Författare :David Roberts; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; traumatology; Kirurgi; ortopedi; orthopaedics; Surgery; knee injuries; knee joint; threshold; anterior cruciate ligament; proprioception;

    Sammanfattning : Proprioceptive ability was estimated in different groups of patients with anterior cruciate ligament (ACL) injury as well as in different groups of healthy uninjured individuals. In study I, patients with poor outcome of the ACL injury – i.e. LÄS MER

  7. 5. Exploratory Study of Novel Materials Used for Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFC) Electrolytes

    Författare :Junfu Bu; Pär Jönsson; Zhe Zhao; Christopher Knee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hafnium oxide; Solid oxide fuel cells SOFCs ; Electrolyte; Electrochemical impedance spectroscopy; Solid state reaction method; Solid state reactive sintering SSRS ; Ionic conductivity; oxygen ion conductivity; Protonic conductivity; Composite electrolyte.;

    Sammanfattning : Currently, yttria-stabilized zirconia (YSZ) is still the dominant electrolyte material in commercial SOFC applications. But it has severe drawbacks due to its high operating temperatures. In present work, two electrolyte materials: Hf0.69Y0. LÄS MER
