“Background: Accurate and precise tunnel placement is critical to the success of anterior cruciate ligament (ACL) reconstruction. A new development, computer-assisted surgery,
aids in placement of the ACL bone tunnels during surgery. Our hypothesis was that computer-assisted ACL reconstruction would allow more accurate and precise tunnel placement compared with conventional surgery.
Methods: In a prospective, double-blind, randomized clinical study, 100 patients eligible for ACL reconstruction with a transtibial technique were stratified by surgeon and randomized to either conventional or computer-assisted surgery. Measurement of femoral and tibial tunnel placement with use of three-dimensional computed tomography (CT) was used as the APR-246 ic50 primary outcome to compare conventional ACL surgery with computer-assisted PLX4032 MAPK inhibitor surgery.
Results: The placement of the femoral tunnel did not differ between groups (mean, 39.7% of the proximal-distal distance on the intracondylar axis [Blumensaat line] in the conventional group compared with 39.0% in
the computer-assisted surgery group; p = 0.70). The anterior-posterior positioning of the tibial tunnel on the tibial plateau also did not differ significantly (38.9% in the conventional group compared with 38.2% in the computer-assisted surgery group; p = 0.58). There was no significant difference in the precision of either the femoral or the tibial tunnel placement between the two groups.
Conclusions: There was no significant difference in either the accuracy or the precision of tunnel placement C188-9 ic50 between conventional and computer-assisted ACL reconstruction.”
“The grafting of 4-vinyl pyridine (4-VP) onto konjac glucomannan (KGM) by ammonium persulfate (APS) as the initiator was studied in an acid aqueous solution under an inert
atmosphere. The grafting ratio (G%) and grafting efficiency (E%) were evaluated comparatively. The dependence of these parameters on the initiator concentration, sulfuric acid concentration, ratio of monomer to KGM, temperature, and reaction time was also investigated. Under conditions of [KGM] = 1.00 g/L, [APS] = 1.00 x 10(-2) mol/L, [4-VP] = 9.32 x 10(-2) mol/L, [H(+)] = 5.00 x 10(-2) mol/L, temperature = 35 degrees C, and time = 120 min, the optimum G% and E%, were 307.27 and 52.75%, respectively. The proof of grafting was obtained from thermogravimetric analysis and infrared spectra. Preliminary research of the graft’s adsorption capacity for heavy-metal ions [Cr(VI), Cu(II), Pb(II), and Cd(II)] was done. (C) 2009 Wiley Periodicals, Inc. J Appl polym Sci 113: 2339-2345, 2009″
