Implication

In vivo study demonstrates localized surface defects during suture degradation in rats, suggesting these flaws do not drive early loss of mechanical strength.

Key Points

Investigate topographical and surface changes that occur during the degradation of known and potentially absorbable suture materials.
Subcutaneously implanted loops of plain catgut, chromic catgut, polylactic acid, polyglycolic acid, polyester A, and polyester B in rats for 2 to 14 weeks.
Harvested implants at designated intervals and evaluated surface defects using scanning electron microscopy without further specimen treatment.
Biodegradation generated specific, localized structural defects across all evaluated suture materials over time.
The delayed onset of observed surface flaws relative to mechanical decline indicates that exterior defect formation does not cause early loss of tensile strength.
