1. 1. 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

3. 2. On Fixation of Hip Prostheses

   Författare :Lars Palm; Ingemar Ivarsson; Ola Wahlström; Jan Milbrink; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fixation; Hip prostheses; primary arthroplasty; revision arthroplasty; cemented; uncemented; bone grafting; Fixation; Höftprotes; primärartroplastik; revisionsartroplastik; cement; cementfri; bentransplantation; Orthopaedics; Ortopedi;

   Sammanfattning : This thesis, comprising 5 separate studies, is concerned with fixation of prosthetic components in total hip arthroplasty. The results and conclusions of the studies fol-low;The initial stability of femoral revision components, the long cementless PCA stem and the Exeter standard stem cemented in a bed of impacted bone graft, was com-pared in an experimental study.

4. 3. New polymer materials in total hip arthroplasty. Evaluation with radiostereometry, bone densitometry, radiography and clinical parameters

   Författare :Georgios Digas; Göteborgs universitet; []
   Nyckelord :Total hip arthroplasty; polyethylene; bone cement; wear; fixation; and radiostereometry.;

   Sammanfattning : Aims: To evaluate the outcome of different types of polyethylene, bone cements and one design of uncemented fixation with porous and ceramic coating using radiostereometry, bone densitometry, conventional radiography and clinical parameters.Materials and methods: Study 1: 201 patients were extracted from 5 prospective randomised studies to evaluate femoral head penetration at two years with radiostereometry in four basic designs, cemented Lubinus and Reflection cups, uncemented Trilogy and Reflection cups.

5. 4. Clinical and experimental studies on total hip arthroplasty

   Författare :Sven-Arne Jacobsson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : In a 12-year follow-up study, a low-friction, metal-on-plastic hip prosthetic system (Charnley) was compared with a high-friction, metal-on-metal prosthetic system (McKeeFarrar) in a consecutive series of 169 patients, mean age 67 at the start. Satisfactory results were reported in 92 percent of the patients. LÄS MER

7. 5. Knee joint kinematics, fixation and function related to joint area design in total knee arthroplasty

   Författare :Johan Uvehammer; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; polyethylene insert; kinematics; migration; clinical outcome; inducible displacement of the tibial component; radiostereometry.;

   Sammanfattning : The aim was to study the influence of different designs of the joint area on tibial component fixation, kinematics and clinical outcome after a cemented total knee arthroplasty (TKA). The HSS score and a special questionnaire were used at the clinical examination. LÄS MER
