Absorbable sutures play a critical role in modern surgical procedures by eliminating the need for removal while supporting proper wound healing. Among them, polyglycolic acid (PGA) sutures are widely used due to their predictable absorption profile and reliable mechanical performance. For procurement teams and medical distributors, understanding how long an absorbable surgical suture remains functional—and what influences its degradation rate—is essential for selecting the right product for specific clinical applications.
Typical Absorption Period of PGA Sutures
Polyglycolic acid sutures are designed to be fully absorbed by the body through hydrolysis. Under normal physiological conditions, complete absorption generally occurs within 60 to 80 days. During this period, the absorbable surgical suture gradually breaks down into biocompatible byproducts that are safely metabolized. This predictable timeline makes PGA sutures suitable for soft tissue procedures where temporary wound support is required without long-term foreign material retention.
Tensile Strength Retention and Wound Support
Beyond total absorption time, tensile strength retention is a key performance indicator. A high-quality absorbable surgical suture must maintain sufficient strength during the critical early stages of healing. PGA sutures typically retain around 75% of their original tensile strength after 14 days and approximately 40% after 21 days. This controlled decline provides reliable mid-term support, aligning well with the healing requirements of many general and soft tissue surgeries.
Factors Influencing Degradation Rate
Several variables can affect how quickly an absorbable surgical suture degrades. Patient-specific factors such as tissue environment, pH levels, and infection risk may accelerate or slow hydrolysis. Surgical site location and local blood supply also play a role. From a sourcing perspective, consistent raw materials and precise manufacturing processes are equally important, as they ensure uniform absorption behavior across batches.
