  2. 1. Gait and motion analysis of hip arthroplasty. Validity, reliability and longterm results

    Author : Roland Zügner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait analysis; Hip arthroplasty; Kinematics; Radiostereometric analysis; Hip osteoarthritis;

    Abstract : Introduction: Walking is one of the most fundamental activities of daily living in humans, when the hip joints transfer power between the lower extremities and the pelvis. Hip osteoarthritis (OA) will more or less influence this function and is increasing in an ageing population. READ MORE

  4. 2. Fixation of the cemented tibial component : a radiostereometric analysis

    Author : Hans Christian Hyldahl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. READ MORE

  5. 3. Anterior cruciate ligament injury. Results after reconstruction in terms of function, postoperative pain and kinematics

    Author : Sveinbjörn Brandsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; reconstruction; bone-patellar tendon-bone graft; post-operative pain; morphine; pain reduction; kinematics; radiostereometric analysis; RSA.;

    Abstract : The aim of this study was to evaluate the functional and objective outcome after anterior cruciate ligament reconstruction using bone-patellar tendon-bone grafts. Other main objectives were to evaluate postoperative pain, pain reduction and knee kinematics after anterior cruciate ligament injury and reconstruction. READ MORE

  6. 4. Evaluation of methods of measuring wear of polyethylene acetabular components intotal hip arthroplasty

    Author : Charles R Bragdon; Göteborgs universitet; []
    Keywords : Total hip replacement; polyethylene; wear; radiostereometric analysis; radiograph;

    Abstract : Background: The introduction of highly cross-linked, wear resistant polyethylene acetabularcomponents for clinical use in total hip replacements has intensified the interest in and need for highlyaccurate methods of measuring wear from clinical radiographs. There are several methods currentlyavailable for measuring the relative displacement of the femoral head into the acetabular componentresulting from the combination of plastic deformation and wear of the polyethylene bearing surface.

  7. 5. Allograft bone in hip revision: the effect of locally applied pharmacological treatment

    Author : Ola Belfrage; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allograft bone; bone transplantation; bisphosphonate; bone morphogenetic proteins; hip revision; radiostereometric analysis;

    Abstract : The clinical success of primary hip replacement is paramount but the need for revisions will continue to increase due to the increasing number of operated individuals. In Sweden, the number of hip revisions in 2012 exceeded 2,300. During implant loosening, some of the bone in the femur is lost, which can make the revision more difficult. READ MORE
