Alignment in total knee arthroplasty. A comparison of computer-assisted surgery with the conventional technique.
Restoration of neutral alignment of the leg is an important factor affecting the long-term results of total knee arthroplasty (TKA). Recent developments in computer-assisted surgery have focused onExpand

Imageless navigation for insertion of the acetabular component in total hip arthroplasty: is it as accurate as CT-based navigation?
In a prospective randomised clinical study acetabular components were implanted either freehand (n = 30) or using CT-based (n = 30) or imageless navigation (n = 30). The position of the component wasExpand

The association of low back pain, neuromuscular imbalance, and trunk extension strength in athletes.
BACKGROUND CONTEXT Imbalanced patterns of erector spinae activity and reduced trunk extension strength have been observed among patients with low back pain (LBP). The association between LBP andExpand

Position of the acetabular cup -- accuracy of radiographic calculation compared to CT-based measurement.
OBJECTIVE A variety of mathematical and trigonometric methods has been described for determining the position of the acetabular cups from conventional radiographs. However, these formulae are subjectExpand

Cumulative occupational lumbar load and lumbar disc disease – results of a German multi-center case-control study (EPILIFT)
BackgroundThe to date evidence for a dose-response relationship between physical workload and the development of lumbar disc diseases is limited. We therefore investigated the possible etiologicExpand

Catecholamine-producing cells in the synovial tissue during arthritis: modulation of sympathetic neurotransmitters as new therapeutic target
Background The proinflammatory and anti-inflammatory role of the sympathetic nervous system in early and late inflammation is an unresolved paradox. A drastic loss of sympathetic nerve fibres in theExpand

Identifying patients with axial spondyloarthritis in primary care: how useful are items indicative of inflammatory back pain?
Background The value of clinical items defining inflammatory back pain to identify patients with axial spondyloarthritis (SpA) in primary care is unclear. Objective To identify predictive clinicalExpand

Navigation in total-knee arthroplastyCT-based implantation compared with the conventional technique
Background Exact axial limb alignment in total-knee arthroplasty (TKA) is important for a successful outcome. We evaluated the efficiency of computer-assisted implantation in TKA and compared it withExpand

Soluble Signalling Factors Derived from Differentiated Cartilage Tissue Affect Chondrogenic Differentiation of Rat Adult Marrow Stromal Cells
Background: Chondral defects show lack of proper regeneration whereas osteochondral lesions display limited regeneration capacity. Latter is probably due to immigration of chondroprogenitor cellsExpand
