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

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

    Abstract : 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. READ MORE

  2. 2. Bisphosphonates for orthopedic applications. Studies in rat models

    Author : Jörgen Åstrand; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; topical treatment; osteonecrosis; bone graft resorption; prosthetic loosening; Bisphosphonates; osteoclasts;

    Abstract : Prosthetic loosening, bone graft resorption and osteonecrosis are examples of problems in orthopedic surgery caused by or augmented by bone resorption. Bone resorption is caused by osteoclasts. Osteoclasts can be inactivated with biphosphonates, a drug in clinical use against osteoporosis and osteolytic tumors. READ MORE

  3. 3. On the aetiology of aseptic loosening in joint arthroplasties, and routes to improved cemented fixation

    Author : Mikael Sundfeldt; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee prosthesis; aseptic loosening; polyethylene particles; endotoxin; bone cement; sodium fluoride;

    Abstract : Background: Aseptic loosening is the most common single cause for revisions in major joint arthroplasties worldwide. Different theories for aseptic loosening have been discussed during the last two decades. There is a need for improving fixation in both cemented and uncemented implants. READ MORE

  4. 4. On loosening and revision in total hip arthroplasty

    Author : Thomas Eisler; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Aseptic loosening; osteolysis; septic loosening; revision; revision total hip arthroplasty; total hip arthroplasty;

    Abstract : Periprosthetic bone resorbtion (osteolysis) and aseptic loosening constitute the major long-term complication in total hip arthroplasty. It has been suggested that osteolysis is the result of the action of osteoclasts generated by prosthetic wear-debris-triggered macrophages. READ MORE

  5. 5. Coagulase-negative staphylococci in prosthetic hip infections

    Author : Åsa Nilsdotter-Augustinsson; Arne Tärnvik; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : More than 11,000 primary total hip replacements were performed in Sweden in the year 2000, corresponding to 125 primary total hip replacements per 100,000 inhabitants, according to The Swedish Total Hip Replacement Register. In general, this procedure provides highly satisfactory results. READ MORE
