  1. 1. Developing knee joint osteoarthritis: Clinical, radiographical and biochemical features

    Författare :Ingemar Petersson; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone markers; cartilage markers; WOMAC; SF-36; function; health status quality-of-life; radiography; epidemiology; knee pain; Knee joint; osteoarthritis; bone scan; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

    Sammanfattning : The aim of this project was to study clinical, radiographical and biochemical features of developing, symptomatic knee osteoarthritis (OA) prospectively in individuals aged 35-54 from the general population. A questionnaire to a random sample of 2 000 individuals in the district of Laholm, Sweden, identified 279 individuals (15% of the population) with chronic (>3 months) knee pain. LÄS MER

  3. 2. Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

    Författare :Torsten Boegård; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; MR imaging; bone scintigraphy; osteophyte; joint space width; weight-bearing; radiograms; Knee joint; osteoarthritis; tomografi; medicinsk instrumentering;

    Sammanfattning : The aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. LÄS MER

  4. 3. Motion analysis of the knee : kinematic artifacts, EMG normalisation and joint forces

    Författare :Daniel L Benoit; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Knee; tibiofemoral joint; kinematics; anterior cruciate ligament; ACL; bone pin; markers; neuromuscular adaptation; electromyography; normalisation; skin movement artifact; joint forces; ski injury; ski boot;

    Sammanfattning : The non-contact anterior cruciate ligament (ACL) injury is the most common and serious debilitating knee joint injury in male and female athletes. To create an ACL injury paradigm that will lead to improved treatment and prevention it is necessary to understand how ACL injuries occur. 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. The normal and ACL deficient knee : an in vivo three dimensional kinematic and electromyographic analysis

    Författare :Dan K Ramsey; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Knee; Tibia; Femur; Tibiofemoral contact points; Tibiofemoral kinematics; Anterior cruciate ligament; ACL injury; Knee brace; Knee instability; Bone pin; Magnetic resonance imaging; NM; Neuromuscular adaptation; Electromyography.;

    Sammanfattning : The overall aim of this thesis was to describe the in-vivo 3D kinematics of the normal and ACL deficient knee. Baseline data from normal controls were compared against the pathological knee to assess whether generic functional knee braces reduced abnormal displacements. Moreover, 3D bony contact movements were derived from MRI data. LÄS MER
