Sutures for Orthopedic Surgery — Tendon, Ligament & Bone Repair Guide
Orthopedic surgery involves repair and reconstruction of musculoskeletal structures that heal slowly and require sustained mechanical support. Tendons, ligaments, and fascial tissues may take 6 to 12 weeks to regain adequate strength, demanding sutures with prolonged tensile strength retention. The choice between absorbable and non-absorbable materials depends on the specific tissue, mechanical loading, and whether permanent fixation is required.
Key Suture Selection Considerations
Extended tissue support is paramount — tendons and ligaments heal slowly, requiring sutures that maintain 70-80% tensile strength beyond 6 weeks post-operatively
High initial tensile strength is needed to withstand early rehabilitation forces, particularly in rotator cuff repair and ACL reconstruction
Monofilament sutures reduce bacterial wicking in deep tissue planes, lowering the risk of surgical site infection around implants and hardware
Non-absorbable sutures are preferred for permanent fixation of tendons to bone (e.g., rotator cuff anchor sutures) and ligament reconstruction
Stainless steel wire may be required for cerclage wiring in fracture fixation and patellar tendon repair
Suture caliber must balance strength requirements with tissue bulk — heavy gauges (0 to 2) for major tendon repairs, finer gauges for capsular and synovial closure
Recommended Desmo Care Sutures
DesmoPol
PDO monofilament providing extended support up to 180 days with 50% strength at 6 weeks — ideal for tendon repair, periosteal closure, and fascial layers where prolonged strength retention matches musculoskeletal healing timelines
DesmoCapro
PLLA-PCL monofilament retaining 80% strength at 90 days — excellent for ligament reconstruction, Achilles tendon repair, and procedures requiring the longest absorbable tissue support available
DesmoSter
316L stainless steel monofilament for cerclage wiring in fracture fixation, patellar tendon re-attachment, and sternal closure in thoracic approaches to the spine
DesmoMid
Polypropylene monofilament with permanent tensile strength — used for rotator cuff anchor fixation, permanent tendon-to-bone suturing, and fascial closure requiring lifelong support
Clinical Notes & Best Practices
The American Academy of Orthopaedic Surgeons (AAOS) recommends suture selection based on tissue healing rates and mechanical demands. For rotator cuff repair, high-strength non-absorbable or ultra-high-molecular-weight polyethylene sutures are standard for tendon-to-bone fixation. Meniscus repair commonly uses long-term absorbable PDO sutures that maintain strength during the 6-12 week healing period. Achilles tendon repair benefits from sutures with at least 90 days of effective tissue support — making PLLA-PCL and PDO monofilament sutures appropriate choices. In fracture fixation, stainless steel cerclage wiring remains essential for periprosthetic fractures and augmenting plate fixation. All orthopedic suture selection should account for the expected rehabilitation protocol and loading timeline.
Frequently Asked Questions
What suture is best for rotator cuff repair?
▼
Rotator cuff repair typically requires non-absorbable high-strength sutures for tendon-to-bone fixation, such as DesmoMid polypropylene or DesmoSter polyester sutures. For capsular and soft tissue closure layers, long-term absorbable sutures like DesmoPol (PDO) or DesmoCapro (PLLA-PCL) provide appropriate support during the 6-12 week healing period.
How long do orthopedic sutures need to maintain strength?
▼
Most musculoskeletal tissues require 6-12 weeks of suture support for adequate healing. Tendons and ligaments are particularly slow-healing structures. Sutures should retain at least 50% tensile strength through the critical healing period — DesmoPol retains 50% at 6 weeks, while DesmoCapro retains 80% at 90 days.
Are absorbable sutures appropriate for ligament surgery?
▼
Long-term absorbable sutures like DesmoCapro (180-day support) and DesmoPol (180-day support) are appropriate for augmenting ligament repairs and closing surrounding capsular tissue. However, the primary ligament fixation (e.g., ACL graft fixation) typically uses non-absorbable or high-strength suture anchors for permanent mechanical support.
When is stainless steel wire used in orthopedic surgery?
▼
Stainless steel wire sutures (DesmoSter) are used for cerclage wiring in periprosthetic fractures, patellar tendon reattachment, tension band wiring of olecranon fractures, and augmenting fracture fixation with plates. Steel provides unmatched tensile strength and permanent support where maximum mechanical stability is essential.
What suture should be used for meniscus repair?
▼
Meniscus repair commonly uses long-term absorbable monofilament sutures like DesmoPol (PDO) in 2/0 to 0 gauge. The extended 180-day tissue support aligns with the slow healing of meniscal tissue, while the monofilament structure minimizes bacterial wicking in the synovial joint environment.
