The purpose of this study was to relate the two-hand (manual) and instrument tie techniques with the ultimate security of granny and square knots constructed in multifilament and monofilament nylon sutures. Instrument-tie technique constructed secure granny and square knots, which failed by breakage rather than slippage. Similarly, two-hand (manual) tie techniques constructed square knots, which achieved knot security, failing only by breakage. In contrast, knot security was not reliably achieved with granny knots constructed by the two-hand (manual) tie techniques, with the knots frequently failing by slippage.
本研究的目的是将双手（手工）打结技术和器械打结技术与用多股和单股尼龙缝线打成的方结和奶奶结的最终安全性联系起来。器械打结技术打出的奶奶结和方结很牢固，是因缝线断裂而非滑脱而失效。同样，双手（手工）打结技术打出的方结能确保结的安全性，也只是因缝线断裂而失效。相比之下，双手（手工）打结技术打出的奶奶结不能可靠地确保结的安全性，这些结经常因滑脱而失效。
