  1. 1. Fixation of the cemented tibial component : a radiostereometric analysis

    Författare :Hans Christian Hyldahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aseptic loosening of the tibial component was the major mode for failure in early uni-(UKA) and total condylar knee arthroplasty (TKA). Metal-backing (MB) was introduced to solve the fixation problem of the tibial component, based on biomechanical experiments. LÄS MER

  3. 2. Kinematics and fixation of total knee arthroplasties : a clinical, radiographic, scintimetric, and roentgen stereophotogrammetric evaluation

    Författare :Kjell G. Nilsson; Johan Kärrholm; Leif Ryd; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; tibial component; kinematics; micromotion; loosening; scintimetry; roentgen stereophotogrammetric analysis;

    Sammanfattning : Aseptic loosening of the tibial component is an important cause of failure after total knee arthroplasty. Bone destruction often claimed to be caused by the cement makes the revision difficult. In order to treat younger patients, uncemented fixation has been introduced, but the etiology to loosening is multifactorial and only partly known. LÄS MER

  4. 3. Osteotomy for gonarthrosis - with special reference to the tibial callus distraction technique

    Författare :Göran Magyar; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; radiography; arthroplasty; complications; coating; hydroxyapatite; external fixator; femoral osteotomy; hemicallotasis; Knee osteoarthritis; tibial osteotomy; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Osteotomy is used for correction of the altered load on the gonarthrotic knee joint. It can be performed above or below the knee. Clinical results depend on the correction after bone healing. LÄS MER

  5. 4. Knee joint kinematics and the effects of arthropasty component design

    Författare :Tuuli Saari; Göteborgs universitet; []
    Nyckelord :Total knee replacement; motion analysis; radiostereometry; migration; kinematics; radiolucent lines; clinical outcome;

    Sammanfattning : Aims: To evaluate the influence of medial osteoarthritis on knee joint kinematics and the effect of design in total knee replacements (TKR) on the kinematics of trunk, hip, knee and ankle. Associations between articulating surface design, clinical outcome and fixation of the tibial component were also evaluated. LÄS MER

  7. 5. 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
