Which of the following is true about silk sutures?

Silk sutures are composed of natural fibers, and one characteristic of silk is its ability to absorb moisture. This property can create potential weak points, especially if the sutures become compromised due to environmental factors such as exposure to fluid. It is essential to consider this quality when choosing silk sutures for a particular surgical procedure, as moisture absorption can impact their performance and longevity in tissue.

The other characteristics of silk sutures include their biodegradability, meaning they will break down over time in the body, but not at the rate that would be considered swiftly absorbable like synthetic absorbable sutures. While silk is generally well-tolerated in the body, it is not entirely non-reactive, as some level of tissue reaction can occur. Additionally, while silk sutures are strong and can offer good tensile strength, they are not considered the strongest type of sutures available when compared to synthetic materials, such as those made from polyester or nylon, which are typically preferred for high-tension situations.
