A total knee arthroplasty performed with navigation results in more accurate component positioning with fewer outliers. It is not known whether image-based or image-free-systems are preferable and if navigation for only one component leads to equal accuracy in leg alignment than navigation of both components. We evaluated the results of total knee(More)
BACKGROUND Elite-level sports activities have been associated with hip osteoarthritis and cam-type deformity. PURPOSE To analyze the appearance and prevalence of an abnormal cam-type deformity of the proximal femur and its potential association to hip pain in adolescent and young adult athletes. STUDY DESIGN Cross-sectional study; Level of evidence, 3.(More)
BACKGROUND AND PURPOSE Computer navigation in total knee arthroplasty is somewhat controversial. We have previously shown that femoral component positioning is more accurate with computed navigation than with conventional implantation techniques, but the clinical impact of this is unknown. We now report the 5-year outcome of our previously reported 2-year(More)
Hydrogen desorption from argon plasma-treated titanium implants with a high surface roughness was studied. Implants with a high surface roughness have shown an increase in mechanical stability in bone tissue and a different behavior of osteoblasts in vitro. High surface roughness was produced by grit blasting and acid etching, resulting in an increase of(More)
The cytotoxicity of a unimolecular polymeric micelle (1) and its degradation products was assessed by cell proliferation and viability with L929 mouse areolar/adipose fibroblasts. Polymer 1 and poly(ethylene glycol) (PEG) were diluted to concentrations from 10(-4) to 10(-6) M in culture media, whereas the degradation products were diluted to concentrations(More)
BACKGROUND Symptoms associated with pes planovalgus or flatfeet occur frequently, even though some people with a flatfoot deformity remain asymptomatic. Pes planovalgus is proposed to be associated with foot/ankle pain and poor function. Concurrently, the multifactorial weakness of the tibialis posterior muscle and its tendon can lead to a flattening of the(More)
INTRODUCTION Surgery for symptomatic aortic abdominal aneurysms (sAAA) is associated with an increased mortality and morbidity compared to asymptomatic aortic aneurysms (aAAA). With the advent of endovascular therapy, an alternative therapeutic modality has become available. Endovascular therapy, however, depends on certain morphologic criteria, whereas(More)
