1. On Fixation of Hip Prostheses
Abstract : 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.

2. Hip revisions with impacted morselized allograft bone and cement. Patient outcome, prosthetic fixation and risks
Abstract : 144 consecutive hip revisions performed with morselized allograft bone and cement were followed up to 5 years after surgery. In 49 hips patient outcome was evaluated with the Nottingham Health Profile (NHP) questionnaire and Charnley hip scores in 47 hips prosthetic fixation was evaluated with radiostereometry (RSA)and in all 144 hips risks and complications were recorded using a prspective protocol.

3. Total knee arthroplasty : Alternative aspects on fixation, design and postoperative treatment
Abstract : Total knee arthroplasty as a treatment of severe gonarthrosis has become a great success, but tibial component loosening is still a major reason for failure. When total knee arthroplasty was introduced, only all-polyethylene (AP) tibial components were available. READ MORE

4. Fixation of the cemented acetabular component in hip arthroplasty
Abstract : In total hip arthroplasty cemented fixation of the acetabular component is a generally successful concept, but the rate of aseptic loosening and consequent revision surgery is still too high. One of the crucial factors for longterm implant survival is the initial fixation and stability. READ MORE

5. New polymer materials in total hip arthroplasty. Evaluation with radiostereometry, bone densitometry, radiography and clinical parameters
Abstract : 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.
