Vicryl is a synthetic absorbable suture made from polyglactin 910, a copolymer of glycolide and lactide. It holds wounds together during the critical healing window and then gradually dissolves inside the body, eliminating the need for suture removal in most cases. Its tensile strength drops to roughly half within two weeks of implantation and is largely gone by six weeks, while full absorption of the material takes about 56 to 70 days. That two-part timeline, strength loss followed by material absorption, is central to understanding how Vicryl works and when surgeons choose it over alternatives.
What Vicryl Is Made Of
Vicryl sutures are composed of polyglactin 910, a synthetic polymer created by combining two building blocks: glycolide (about 90 percent) and L-lactide (about 10 percent). The resulting material is braided, meaning multiple fine filaments are woven together into a single strand, then coated to reduce friction as the suture passes through tissue. This braided structure gives Vicryl good handling characteristics and strong knot security. In lab testing, Vicryl has demonstrated the greatest knot security among common suture types including chromic gut, nylon, and silk.1PubMed. Knot Security- How is it Affected by Suture Technique, Material, Size, and Number of Throws? Multifilament sutures like Vicryl also have less “memory” than single-strand (monofilament) sutures, meaning the material does not spring back into a curled shape, which makes it easier for surgeons to work with.2PLoS One. Experimental investigation of tensile properties and fracture behavior of ophthalmic sutures under straight, knotted, and looped configurations: Vicryl, nylon, and polypropylene
The trade-off with a braided design is that the tiny spaces between filaments can, in theory, harbor bacteria more readily than a smooth monofilament surface. This is one reason Ethicon (the Johnson & Johnson subsidiary that manufactures Vicryl) developed antibacterial-coated variants, which are discussed further below.
The Two Timelines That Matter
When people ask “how long do Vicryl sutures last,” they usually mean one of two things: how long the suture holds the wound edges together (tensile strength retention), and how long the material sticks around in the body before it is fully absorbed. These timelines are different, and confusing the two leads to a lot of unnecessary worry.
Tensile strength is the suture’s ability to resist being pulled apart. Vicryl retains about 75 percent of its original strength at two weeks and roughly 50 percent at three weeks. By day 42, lab testing has shown that a size-2 Vicryl suture’s breaking strength can fall from around 195 newtons on the day of placement to about 14 newtons, at which point it no longer provides meaningful wound support.3PubMed Central. Two-month longitudinal study of mechanical properties of absorbable sutures used in orthopedic surgery An in-vivo comparison of absorbable sutures found that Vicryl’s half-life for tensile strength is about two weeks, matching another common braided suture (Dexon Plus) and falling well short of the monofilament alternatives Maxon (three weeks) and PDS (six weeks).4PubMed. In-vivo comparison of four absorbable sutures: Vicryl, Dexon Plus, Maxon and PDS
Complete absorption of the suture material happens later, typically between 56 and 70 days after placement.5PubMed Central. The Time to Spontaneous Drop of Polyglactin 910 (Vicryl) in the Nasal Cavity During this window, the polymer chains are broken down by water (hydrolysis) and gradually absorbed by the surrounding tissue. So a suture might stop holding the wound together after four to five weeks, but remnants of the thread may still be visible or palpable for another few weeks beyond that. In most surgical settings, the wound has healed well enough by the time the suture loses its strength that the weakening does not matter.
What Affects How Quickly They Break Down
The body is not a uniform environment, and the speed at which Vicryl degrades depends on where it is placed and what conditions surround it. The most significant variable is pH. Laboratory studies comparing Vicryl and polyglycolic acid sutures across acidic, physiological, and high-alkaline conditions found that Vicryl retained the highest tensile strength at normal body pH (around 7.44) and lost strength faster in both acidic and strongly alkaline environments.6PubMed Central. A comparison of the effect of pH on the biodegradation of two synthetic absorbable sutures This means Vicryl performs best in tissues with a normal, healthy blood supply. In infected wounds, where local pH often drops due to bacterial metabolism and inflammation, the suture may weaken faster than expected.
Location in the body also plays a role. When Vicryl sutures were placed in the nasal cavity and tracked over time, those on the lateral nasal wall persisted longer than those on the nasal septum, with half-lives of 70 days and 64 days respectively.5PubMed Central. The Time to Spontaneous Drop of Polyglactin 910 (Vicryl) in the Nasal Cavity In some patients, sutures remained visible in the nasal cavity for up to three months. The lesson here is that the “56 to 70 days” figure is an average, not a guarantee, and certain anatomical sites with less blood flow or moisture contact may hold onto suture material longer.
Other factors that can influence degradation speed include the thickness of the suture (thicker gauges contain more polymer and take longer to dissolve completely), whether the wound is under mechanical stress (movement can accelerate breakdown), and the patient’s individual healing biology. Surgeons factor these variables in when choosing the suture and its size for a given procedure.
Vicryl Variants
Not all sutures labeled “Vicryl” are exactly the same product. Two important variants exist, each designed for a different clinical situation.
Vicryl Rapide is an irradiated version of standard Vicryl that breaks down much faster. It retains tensile strength for only about 10 to 14 days and is substantially absorbed by 42 days. Surgeons often reach for Vicryl Rapide when closing skin or superficial wounds where only short-term support is needed and early suture dissolution is an advantage. In ophthalmic plastic surgery, researchers found no visible suture marks at two months when using either standard 7/0 Vicryl or 7/0 Vicryl Rapide for skin closure, suggesting both dissolve cleanly in fine-gauge applications near the eyes.7PubMed. Use of 7/0 Vicryl (coated polyglactin 910) and 7/0 Vicryl-rapide (irradiated polyglactin 910) in skin closure in ophthalmic plastic surgery
Vicryl Plus is standard Vicryl coated with triclosan, an antibacterial agent. The coating creates a zone around the suture where bacteria struggle to colonize. In lab testing, Vicryl Plus inhibited the growth of both gram-positive and gram-negative bacteria, and this antibacterial effect did not diminish even after the suture was soaked in fluid for up to seven days or passed through tissue multiple times.8PubMed. In vitro antimicrobial evaluation of Coated VICRYL Plus Antibacterial Suture (coated polyglactin 910 with triclosan) using zone of inhibition assays Animal studies confirmed lower bacterial counts at mesh implant sites and lower levels of inflammatory molecules when Vicryl Plus was used instead of standard Vicryl.9PubMed.

How Vicryl Compares to Other Absorbable Sutures
Vicryl is far from the only absorbable suture on the market, and understanding how it stacks up against the competition helps explain why surgeons pick one material over another.
Compared to monofilament absorbable sutures like PDS (polydioxanone) and Maxon (polyglyconate), Vicryl is stronger in the first couple of weeks but loses that advantage quickly. During the early critical period of wound healing, Vicryl’s tensile strength and that of Maxon both exceeded PDS and chromic catgut. Over the longer postoperative stretch, however, Maxon and PDS held onto a larger percentage of their strength while Vicryl was largely absorbed.11PubMed. Comparison of Maxon suture with Vicryl, chromic catgut, and PDS sutures in fascial closure in rats This means PDS is often the better choice for deep fascial closures where extended strength retention is important, while Vicryl excels where high initial holding power matters more than long-term support.
Against Monocryl (poliglecaprone 25), another popular absorbable suture, Vicryl tends to provoke a slightly stronger local inflammatory response. A comparative case study found that Monocryl offered better early wound comfort, less induration (hardness at the wound site), and higher cosmetic satisfaction in subcutaneous fat closure during cesarean delivery.12Annals of African Medicine. Does Suture Choice Matter? Vicryl versus Monocryl in Subcutaneous Fat Closure Monocryl’s smooth monofilament profile likely contributes to less tissue drag and irritation. That said, its knot security is lower, which is the perennial trade-off between braided and monofilament designs.
Chromic catgut, the traditional absorbable suture derived from animal intestine, has largely fallen out of favor in many surgical specialties. It provokes more tissue reaction than synthetic options, degrades less predictably, and its tensile strength retention during the healing window is generally inferior to Vicryl’s.
Tissue Reaction and Biocompatibility
Any foreign material placed inside the body triggers some degree of immune response, and sutures are no exception. The question is how much. In animal comparisons, Vicryl has generally produced mild tissue reactions. One study in rats found that Vicryl triggered the mildest tissue reaction among the suture materials tested at every time point, with significantly lower total inflammatory cell counts than catgut.13PubMed. Comparison of four different suture materials in soft tissues of rats Another study reported that 80 percent of animals in the Vicryl group showed only mild inflammatory infiltration, with no significant differences in fibrosis or new blood-vessel formation compared to other suture groups.14Journal of Experimental and Molecular Pathology. A comparative study of biological reactions to different suture materials in animal model
That said, a mild reaction is still a reaction. The braided structure of Vicryl means it has a larger surface area in contact with tissue than a monofilament suture of the same gauge, which may partly explain why monofilament alternatives sometimes edge it out on cosmetic and comfort outcomes. For most internal applications, the difference is clinically insignificant, and Vicryl remains one of the most widely used sutures in surgery precisely because its tissue compatibility is reliable and well understood.
When Things Go Wrong
Complications from Vicryl sutures are uncommon, but they do occur. The most talked-about issue is suture granuloma, a lump of inflammatory tissue that forms around a suture remnant when the body’s immune response is more aggressive than usual. A case series documented 10 patients who developed exaggerated tissue reactions and delayed wound healing at sites closed with coated polyglactin sutures. Nine of those patients required surgical removal of the granulation tissue along with residual suture material; one case resolved when the suture spontaneously extruded through the skin.15Malaysian Journal of Oral and Maxillofacial Surgery. Suture Granuloma Associated with Triclosan Coated Polyglactin 910 Sutures
Suture granulomas can appear as firm, sometimes tender nodules at or near the incision weeks after surgery. They are not infections, though they can be mistaken for one. The treatment is usually straightforward: if the granuloma does not resolve on its own, a surgeon can excise the lump and any remaining suture material. These reactions are more commonly reported with braided sutures than monofilament ones, and they can occur with any absorbable material, not just Vicryl.
Another potential issue is suture spitting, where a piece of dissolving suture works its way to the skin surface and pokes through. This is more of a nuisance than a medical emergency. Patients often notice a small, stiff thread poking out of an otherwise healed incision. In most cases, the protruding material can be trimmed, and the area heals without further trouble.
Where Vicryl Is Commonly Used
Vicryl is one of the most versatile sutures in the surgical toolkit. Its combination of strong initial holding power, predictable absorption, and manageable tissue reaction makes it suitable for a broad range of procedures. Common applications include:
- General surgery: closing peritoneum, fascia, and subcutaneous tissue layers during abdominal operations.
- Obstetrics and gynecology: repairing episiotomies and perineal tears, closing uterine incisions during cesarean delivery.
- Oral and dental surgery: closing mucosal incisions after extractions or other intraoral procedures.
- Ophthalmology: fine-gauge Vicryl and Vicryl Rapide for delicate eyelid and conjunctival repairs.
- Otolaryngology: suturing mucosal flaps inside the nasal cavity after sinus or septoplasty procedures.
- Orthopedics: closing soft-tissue layers and repairing tendons where early strength matters more than prolonged support.
In nasal surgery, for example, surgeons sometimes let the Vicryl sutures dissolve naturally rather than scheduling a follow-up for removal. Since the sutures can persist in the nasal cavity for up to three months, some practitioners prefer to remove them one to two weeks postoperatively to avoid prolonged foreign-body sensation, but many leave them in place without complications.5PubMed Central. The Time to Spontaneous Drop of Polyglactin 910 (Vicryl) in the Nasal Cavity
What Patients Should Expect After Surgery
If your surgeon used Vicryl sutures internally, you probably will not see or feel them at all. The sutures do their job beneath the surface and dissolve without any action on your part. If Vicryl or Vicryl Rapide was used on the skin surface, you may see the stitches for the first couple of weeks before they begin to loosen and fall away. Vicryl Rapide skin sutures typically fall out or can be gently wiped away within 10 to 14 days. Standard Vicryl skin sutures take longer, and some surgeons prefer to trim or remove them at a follow-up visit rather than waiting for full dissolution, particularly in cosmetically sensitive areas where a suture sitting on the surface for weeks might leave a more visible mark.
A common source of anxiety is seeing what looks like a small thread poking through the skin or feeling a bump under the incision line weeks after surgery. In most cases, this is either the suture material working its way to the surface (spitting) or mild swelling around the dissolving thread. Neither requires emergency care, but both are worth mentioning at your next appointment so the area can be inspected. Signs that do warrant prompt attention include increasing redness, warmth, pus, or worsening pain at the incision site, all of which could indicate infection rather than a normal suture reaction.
Why Surgeons Still Reach for Vicryl
Despite newer suture technologies, Vicryl remains one of the most heavily used absorbable sutures worldwide, and for good reason. Its strength-to-absorption profile hits a sweet spot for the majority of soft-tissue closures: strong enough in the first two to three weeks to keep wound edges together during the most vulnerable healing period, then predictably gone within about two months. The braided design handles well, ties securely, and gives surgeons consistent performance across different tissue types. The availability of variants like Rapide for faster dissolution and Plus for antibacterial protection further extends its usefulness without requiring a fundamentally different suture-handling technique. For patients, the practical upshot is straightforward: Vicryl sutures generally dissolve on their own schedule, rarely cause problems, and rarely need a second procedure to remove them.
