You will also learn how PDS sutures compare to alternatives and why they enhance surgical outcomes with minimal tissue reaction. Whether you are a medical professional or simply interested in surgical innovations, this article provides valuable insights into one of the most reliable sutures in modern medicine.
What Are Polydioxanone Sutures?
Polydioxanone (PDS) sutures are a type of synthetic, absorbable suture commonly used in surgical procedures. Made from a polyester polymer called polydioxanone, these sutures are designed to provide strong wound support during the critical healing phase and gradually absorb into the body over time. Since they do not require removal, PDS sutures are particularly useful in internal tissues where long-term support is needed.
PDS sutures are monofilament, meaning they consist of a single strand, which reduces tissue drag and the risk of infection compared to multifilament sutures. Their smooth surface ensures minimal trauma to delicate tissues while maintaining high tensile strength for several weeks post-surgery. Typically, PDS sutures retain approximately 70% of their strength after two weeks and fully absorb within six months, depending on the patient’s metabolism.
Common Uses of PDS Sutures
Polydioxanone sutures are widely used in various surgical disciplines, including:
- General Surgery: For abdominal closure, hernia repair, and bowel anastomosis.
- Cardiovascular Surgery: In vascular anastomosis and pediatric cardiac procedures due to their flexibility and biocompatibility.
- Obstetrics and Gynecology: For uterine and perineal repair after childbirth.
- Orthopedic Surgery: To reattach ligaments and tendons where prolonged support is necessary.
- Plastic Surgery: For delicate skin closures with minimal scarring.
Understanding PDS Suture Benefits
The unique properties of PDS sutures offer several advantages in surgical applications:
1. Biocompatibility and Reduced Tissue Reaction
PDS sutures are designed to minimize inflammatory reactions, making them ideal for sensitive tissues. Unlike natural absorbable sutures, such as catgut, PDS sutures provoke a milder immune response, lowering the risk of complications like excessive scarring or infection.
2. Long-Term Tensile Strength
One of the standout benefits of PDS sutures is their extended strength retention. They provide consistent support for weeks, which is crucial for slow-healing tissues such as fascia or muscle. This delayed absorption reduces the likelihood of wound dehiscence (reopening).
3. Monofilament Structure
The single-strand design of PDS sutures prevents bacteria from adhering and colonizing, decreasing postoperative infection rates. Additionally, their smooth surface glides through tissues effortlessly, minimizing trauma during suturing.
4. Predictable Absorption Rate
Unlike other absorbable sutures with variable degradation times, PDS sutures absorb uniformly between 180 and 210 days. This predictability allows surgeons to select them confidently for procedures requiring sustained wound support.
5. Versatility in Surgical Applications
PDS sutures are available in multiple sizes and can be used in both deep and superficial tissues. Their flexibility and knot security make them suitable for a broad range of surgical specialties, from cardiovascular to plastic surgery.
In summary, polydioxanone sutures combine strength, biocompatibility, and ease of use, making them a preferred choice for many surgeons. Their ability to support tissues throughout the healing process while minimizing adverse reactions ensures optimal patient outcomes in diverse medical scenarios.
Top 5 Polydioxanone Suture Brands You Should Know

How PDS Suture (Polydioxanone) Enhances Surgical Outcomes
In modern surgery, the choice of suture material plays a crucial role in determining patient recovery and long-term surgical success. PDS (Polydioxanone) sutures are a monofilament synthetic absorbable option known for their strength, biocompatibility, and gradual absorption. Their unique properties make them ideal for various surgical applications, contributing significantly to improved surgical outcomes.
Superior Strength and Longevity
PDS sutures provide exceptional tensile strength throughout the critical healing phase. Unlike some absorbable sutures that lose strength rapidly, PDS maintains approximately 70% of its strength at 2 weeks and 50% at 4 weeks post-implantation. This gradual strength retention ensures secure wound closure when tissues are most vulnerable, minimizing the risk of dehiscence or premature suture breakdown.
Controlled Absorption Rate
One of PDS suture’s key advantages is its extended absorption period—typically 180 to 210 days. This slow degradation occurs via hydrolysis, reducing inflammatory reactions often seen with faster-absorbing materials. The prolonged presence of PDS provides structural support while naturally breaking down as the tissue regains strength, eliminating the need for suture removal and minimizing foreign body reactions.
Reduced Tissue Reaction
Thanks to its monofilament structure, PDS suture causes less tissue drag and elicits minimal inflammatory response compared to multifilament alternatives. Its smooth surface discourages bacterial adhesion, lowering infection risks—a critical factor in procedures involving potentially contaminated sites, such as gastrointestinal or obstetrical surgeries.
Versatility Across Surgical Applications
PDS sutures are favored in:
- Soft tissue approximation: Abdominal wall closures, hernia repairs.
- Cardiovascular procedures: Vascular anastomoses where prolonged support is needed.
- Pediatric surgery: Growing tissues benefit from PDS’s absorption profile.
- Ophthalmic and plastic surgery: Where minimal scarring and precise handling matter.
Ease of Handling
Surgeons appreciate PDS for its excellent knot security and pliability, allowing precise placement even in deep or confined surgical sites. Its flexibility adapts well to dynamic tissues (e.g., bowel or muscle), maintaining integrity without causing tissue cutting or necrosis.
By combining reliable strength with biocompatible absorption, PDS sutures enhance surgical outcomes through secure wound closure, reduced complications, and optimal healing conditions—making them a trusted choice in demanding surgical environments.
Comparing Ethicon PDS II vs. Other Leading Polydioxanone Suture Brands
Polydioxanone (PDS) sutures are synthetic, absorbable monofilaments widely used in surgeries requiring extended wound support. Ethicon’s PDS II is among the most recognized brands, but competitors like Covidien’s MonoPlus and DemeTech’s Surgilon PDS also offer alternatives. This comparison examines key differences in performance, handling, and pricing.
1. Strength and Absorption Profile
Ethicon PDS II is known for its prolonged tensile strength retention, maintaining approximately 70% of its initial strength at 2 weeks and 50% at 4 weeks. It fully absorbs within 6 months, making it ideal for procedures like abdominal closures.
Comparatively, Covidien MonoPlus has a similar absorption timeline but claims slightly better flexibility due to its proprietary manufacturing. DemeTech’s Surgilon PDS, meanwhile, emphasizes consistency in absorption rates but may vary more in tensile strength retention depending on the surgical site.
2. Handling and Surgical Performance
Surgeons often prefer PDS II for its smooth passage through tissue and secure knot-tying ability with minimal memory. The suture’s monofilament structure reduces tissue drag compared to braided alternatives.
MonoPlus competes closely, with some users noting a softer feel but slightly higher risk of fraying during manipulation. Surgilon PDS, though competitively priced, may require more precise handling due to variability in stiffness across sizes.
3. Infection Risk and Biocompatibility
All PDS sutures exhibit low tissue reactivity, but PDS II leverages Ethicon’s coating technology to further minimize bacterial adherence. Independent studies suggest its hydrophilic surface may reduce infection risks in contaminated wounds.
MonoPlus also performs well in infection-prone settings, while Surgilon PDS relies on its polymer purity for biocompatibility—sometimes at the expense of predictable performance in vascular applications.
4. Cost and Availability
PDS II is typically priced at a premium, justified by its reliability in critical surgeries. MonoPlus offers a mid-range cost, often chosen for budget-conscious settings without sacrificing quality. Surgilon PDS is generally the most affordable but may lack consistent availability in certain regions.
Conclusion
Ethicon PDS II remains a top choice for surgeons prioritizing strength retention and handling precision. However, Covidien MonoPlus and DemeTech Surgilon PDS present viable alternatives depending on cost constraints and specific procedural demands. Evaluating each brand’s trade-offs ensures optimal outcomes for patient care.
