  1. 1. 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

  3. 2. 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

  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. Fixation and load in total knee arthroplasty : a clinical, radiographic, radiostereometric and gait study

    Författare :Maria B Hilding; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :total knee arthroplasty; tibial component loosening; radiostereometric analysis RSA ; alignment; gait analysis; joint loading; flexionmoments; Nottingham Health Profile.;

    Sammanfattning : The treatment of severe gonarthrosis by total knee arthroplasty is generally successful, but tibial component loosening remains a problem. The aim in the present work was to investigate if any association between loading and insufficient tibial component fixation could be found, and if the fixation was affected by the tibial component design differences.

  7. 5. 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
