1. Gait and motion analysis of hip arthroplasty. Validity, reliability and longterm results
Sammanfattning : 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. LÄS MER
2. Fixation of the cemented tibial component : a radiostereometric analysis
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. Anterior cruciate ligament injury. Results after reconstruction in terms of function, postoperative pain and kinematics
Sammanfattning : 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. LÄS MER
4. Evaluation of methods of measuring wear of polyethylene acetabular components intotal hip arthroplasty
Sammanfattning : 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.

5. Shoulder Kinematics and Impingement. Dynamic Radiostereometric analysis of the shoulder
Sammanfattning : Abstract This study aimed to evaluate the three-dimensional kinematics of the shoulder joint in patients with shoulder impingement and controls with focus on three well known diagnostic tests; painful arc test (active abduction), Neer sign (passive elevation) and Hawkins sign. The shoulder rhythm, the speed of motion and if successful treatment of impingement could be associated with changes of the shoulder kinematics were studied Dynamic radiostereometry (RSA) is feasible method to study rotations and translations of the gleonohumeral joint because of its high precision.
