  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

  3. 2. Who should have total hip replacement? Use of patient-reported outcome measures in identifying the indications for and assessment of total hip replacement

    Författare :Meridith E Greene; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient-reported outcome measures; Swedish Hip Arthroplasty Register; Harris Joint Registry; total hip replacement; health-related quality of life; EQ-5D; surgical recommendations;

    Sammanfattning : Background: Total hip replacement (THR) is a successful treatment for end-stage hip osteoarthritis (OA). Patients commonly seek this treatment to improve physical function, diminish pain, and ultimately to increase health-related quality of life (HRQoL). LÄS MER

  4. 3. Knee joint kinematics, fixation and function related to joint area design in total knee arthroplasty

    Författare :Johan Uvehammer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; polyethylene insert; kinematics; migration; clinical outcome; inducible displacement of the tibial component; radiostereometry.;

    Sammanfattning : The aim was to study the influence of different designs of the joint area on tibial component fixation, kinematics and clinical outcome after a cemented total knee arthroplasty (TKA). The HSS score and a special questionnaire were used at the clinical examination. LÄS MER

  5. 4. Clinical and experimental studies on wear and osteolysis in total joint replacement

    Författare :Thord von Schewelov; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; reumatologi; muskelsystem; Skelett; rheumatology locomotion; muscle system; NTx; Skeleton; radiostereometry; osteolysis; wear; Hip; arthroplasty; metabolism; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : Total hip arthroplasty is a very successful procedure. Despite this fact, however, a certain portion of patients has to be revised. One major reason for revision is the wear of the polyethylene leading to loosening and osteolysis. LÄS MER

  7. 5. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements

    Författare :Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; Materials science; Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. LÄS MER
