From the Research
To tie a one-handed surgical knot effectively, it is essential to prioritize the security and integrity of the knot, especially when using monofilament sutures, which are more prone to loosening than braided materials, as noted in studies such as 1. When deciding on the technique for tying a one-handed surgical knot, several factors must be considered, including the type of suture material, the specific surgical procedure, and the surgeon's preference and skill level.
- The choice between monofilament and braided sutures can significantly impact knot security, with monofilament sutures like polypropylene offering high tensile strength but being more susceptible to knot slippage, as discussed in 2 and 1.
- The technique itself involves holding the suture in the dominant hand and creating a loop around the needle holder, then grasping the short end of the suture and pulling both ends in opposite directions to tighten the knot, similar to the method described in 3.
- For added security, alternating between throwing loops clockwise and counterclockwise to create square knots rather than slip knots is recommended, as this enhances knot stability and reduces the risk of knot failure, a principle supported by the findings in 4.
- Maintaining tension throughout the process and ensuring the knot is tight enough to secure tissue without damaging the suture material or compromising tissue viability are critical, as emphasized in the context of optimizing arthroscopic knots using braided or monofilament suture 4.
- Given the potential for suture damage, especially with monofilament materials like polypropylene, as highlighted in 2, careful handling and avoidance of excessive tension or deformation during knot tying are crucial.
- Ultimately, the goal is to achieve a secure knot that minimizes the risk of failure while preserving tissue integrity, which can be facilitated by selecting appropriate suture materials and mastering the one-handed knot-tying technique, as informed by studies such as 5.
