RSA wear measurements with or without markers in total hip arthroplasty.
Novel algorithms for radiostereometric (RSA) measurements of the femoral head and metal-backed, hemi-spherical cups of a total hip replacement are presented and evaluated on phantom images andExpand

Very low wear of non-remelted highly cross-linked polyethylene cups: An RSA study lasting up to 6 years
Background and purpose Highly cross-linked polyethylenes (PEs) all appear to reduce wear dramatically in laboratory studies, although there is substantial variation in this respect betweenExpand

In vivo wear and migration of highly cross-linked polyethylene cups a radiostereometry analysis study.
In 50 cemented hip arthroplasties, wear and migration of the polyethylene (PE) cups were measured with radiostereometric analysis for a period of 2 years. Twenty had a normal gamma-in-air-sterilizedExpand

Migration Pattern of a Short Femoral Neck Preserving Stem
The CFP stem represents a short collared neck-retaining stem with very proximal metaphyseal anchoring along the calcar combined with up-to-date metallurgy. Despite theoretical advantages, theExpand

Effect of augmented cup fixation on stability, wear, and osteolysis: a 5-year follow-up of total hip arthroplasty with RSA.
To evaluate different modes of cementless fixation of hemispherical cups, we operated on 87 hips in 81 patients using 4 different means of cup fixation. The hips were randomly assigned to fixationExpand

Intraoperative ligament laxity influences functional outcome 1 year after total knee arthroplasty
AbstractPurpose To find out if there is an association between ligament laxity measured intraoperatively and functional outcome 1 year after total knee arthroplasty (TKA).MethodsMedial and lateralExpand

No adverse effects of submelt-annealed highly crosslinked polyethylene in cemented cups
Background and purpose Highly crosslinked polyethylene (PE) is in standard use worldwide. Differences in the crosslinking procedure may affect the clinical performance. Experimenatal data fromExpand

Porous-coated cups fixed with screws: A 12-year clinical and radiostereometric follow-up study of 50 hips
Background Excellent mid-term results have stimulated the use of hemispherical porous-coated cups in hip replacement. With longer follow-up, there have been problems related to polyethylene wear andExpand

A prospective randomized study comparing electrochemically deposited hydroxyapatite and plasma-sprayed hydroxyapatite on titanium stems
Background and purpose Plasma-sprayed hydroxyapatite (HA) is a successful coating for fixation of uncemented femoral stems. There may be alternative coatings with advantages in bone remodeling andExpand

No radiological and clinical advantages with patient-specific positioning guides in total knee replacement
Background and purpose — Although the use of patient-specific positioning guides (PSPGs) in total knee replacement (TKR) in theory is promising, the technique has not yet proven its superior- ityExpand
