Shortcuts in arthroscopic knot tying: do they affect knot and loop security?
When all tying techniques are considered, surgeon's knots outperform Tennessee sliding knots. Shortcut techniques do not alter the properties of surgeon's knots. However, when used to secure Tennessee sliding knots, shortcuts lead to unacceptably high rates of knot slippage and catastrophic failure as well as decreased knot security.
The results suggest that, although simulators can reveal systematic differences between devices of the same model, they cannot be used to detect systematic differences between different NIBP models. This could be at least partly because the oscillometric pulses generated by the simulators are dissimilar to physiologically recorded pulses.
