A random sample of 1,200 employees of a steel plant in the western United States was randomly assigned to four different self-report methods of assessing illicit drug use: individual interview in the workplace, group-administered questionnaire in the workplace, telephone interview, and individual interview off the worksite. Urine specimens were collected(More)
Synovial mesenchymal stem cells (SMSC) possess a high chondrogenic differentiation potential, which possibly supports natural and surgically induced healing of cartilage lesions. We hypothesized enhanced chondrogenesis of SMSC caused by the vicinity of chondrocytes (CHDR). Human SMSC and CHDR interactions were investigated in an in-vitro trans-well(More)
BACKGROUND Our study aim was to compare allogeneic cancellous bone (ACB) and synthetic or highly-processed xenogeneic bone substitutes (SBS) in the treatment of skeletal defects in orthopedic surgery. METHODS 232 patients treated for bony lesions with ACB (n = 116) or SBS (n = 116) within a 10-year time period were included in this case-control study.(More)
Some cardiac pacemakers maintain constant energy per stimulus by automatically increasing the stimulus duration as battery depletion causes the stimulus amplitude to decline. This feature does not guarantee an invariant capture safety margin, however, because the stimulus energy at threshold increases for stimulus durations exceeding the geometric mean of(More)
In a retrospective study with a population over 65 years, sports activity was conducted 6 years after cruciate retaining (CR) total condylar knee arthroplasty (TKA) with rotating platform (RP). Eighty-one Patients (71.8±5.4years) were examined at follow-up 6.4±0.9 years postoperative. Sport was practiced 5.3 hours every week in mean. Patients were active in(More)
BACKGROUND In a noticeable percentage of patients anterolateral rotational instabilities (ALRI) remain after an isolated ACL reconstruction. Those instabilities may occur due to an insufficiently directed damage of anterolateral structures that is often associated with ACL ruptures. Recent publications describe an anatomical structure, termed the(More)
Erratum After publication of the original article [1], the authors noticed an error in the 'Methods' section. Within the 'Patients' subsection , the first item in the list of synthetic or highly processed xenogeneic bone substitutes (SBS) should have been given as Orthoss®, rather than BioOss®. The sentence should therefore have read as follows: trial and(More)
The aim of this study was the development of a process for filling the pores of a β-tricalcium phosphate ceramic with interconnected porosity with an alginate hydrogel. For filling of the ceramics, solutions of alginate hydrogel precursors with suitable viscosity were chosen as determined by rheometry. For loading of the porous ceramics with the gel the(More)
Non-invasive evaluation of knee joint laxities is crucial in the diagnostics of post-traumatic knee injuries such as ACL ruptures. Current clinical standard and daily routine for orthopaedic surgeons are for instance the Lachman-Test or the Anterior Drawer-Test in the evaluation of knee joint displacement. Those tests, while quickly and easily performed,(More)
Background. Intra-articular infections can rapidly lead to osteoarthritic degradation. The aim of this clinical biomarker analysis was to investigate the influence of inflammation on cartilage destruction and metabolism. Methods. Patients with acute joint infections were enrolled in a prospective clinical trial and the cytokine composition of effusions (n =(More)
