There were ten revisions: seven because of infection, one because of patellar fracture, one because of instability, and one because of aseptic loosening.

CONCLUSIONS: The two designs functioned equivalently at the time of early follow-up in this low-to-moderate-demand patient group. The rotating-platform design had no significant clinical advantage over the design with the all-polyethylene tibial component.

“Purpose: Atherosclerosis is thought to be initiated by the transendothelial migration of monocytes. In the early stage of this process, the adhesion of monocytes to endothelial cells is supported by an increase in the intracellular concentration of calcium ion ([Ca2+]i) in endothelial cells. However, the main

source of Ca2+ has been unclear. learn more In this study, the changes in ionic transmittance and [Ca2+]i due to the adhesion of monocytes were continuously measured by an electrophysiological technique and fluorescent imaging. Especially, we focused on transient receptor potential vanilloid channel 1 (TRPV1) as a Ca2+ channel that could influence the adhesion of monocytes.

Material and methods: Whole-cell current was continuously recorded in human umbilical vein endothelial cells (HUVECs) by a patch electrode.

Results: The adhesion of monocytes (THP-1) induced a transient inward current in HUVECs, as well as an elevation of [Ca2+]i. This inward element was abolished by the application of 100nM SB366,791, a selective antagonist of TRPV1 channel. Furthermore, SB366,791 significantly decreased the number of THP-1 cells that adhered to HUVECs (control: 231 +/- 38, SB366,791: GPCR Compound Library in vivo 96 +/- 16 cells/mm2).


These results suggest that an inward calcium current via the TRPV1 channels of endothelial cells correlates with a stronger adhesion between monocytes and endothelial cells.”
“BACKGROUND: Insertion of a radial head implant that results in radial overlengthening has been associated with altered elbow kinematics, increased radiocapitellar joint forces, capitellar erosions, early-onset arthritis, and loss of elbow flexion. The purpose of this study was to identify clinical and radiographic features that may be used to diagnose overlengthening of the radius intraoperatively and on postoperative radiographs.

METHODS: Radial head implants of varying thicknesses were inserted into seven cadaver specimens, which were then assessed clinically and radiographically.
