Composite Absorbable Anchor System - Biodegradable Fixation for Orthopedic Soft Tissue Repair
Engineered for biocompatible and long-lasting bone-to-soft tissue fixation, the Composite Absorbable Anchor System combines advanced biodegradable materials with specialized structural designs. This innovative system eliminates the need for secondary implant removal surgery, promotes natural tissue healing, and adapts to a wide range of orthopedic procedures-setting a new standard for minimally invasive joint repair.
Core Advantages
Biodegradable Composite Material for Safe Absorption: Crafted from a biocompatible composite (e.g., PLGA/HA blend), the anchor gradually degrades within 12–24 months post-surgery, being fully absorbed by the body without residual foreign matter. This eliminates the risk of long-term implant-related complications and avoids the need for secondary removal procedures, reducing patient trauma and recovery time.
Bioactive Design to Accelerate Tendon-Bone Healing: The composite material's porous structure and bioactive components facilitate bone cell ingrowth and vascularization, bridging the gap between soft tissue and bone. Hollow and fully 镂空 (hollowed-out) designs further enhance bone integration, accelerating tendon-bone healing and improving long-term repair stability.
Versatile Anchor Types for Multisurgical Needs: Available in five specialized variants-Solid Strike-In, Hollow Strike-In, Split Spin-In, Full Hollow Screw-In, and Conventional Spin-In-each tailored to specific clinical scenarios. From small joint repairs (e.g., hand, wrist) to complex reconstructive procedures (e.g., rotator cuff repair, ACL reconstruction), the system adapts to diverse anatomical sites and surgical approaches.
User-Friendly Features to Streamline Surgery: Supports knotless fixation (via wide suture holes and split-body designs) and adjustable suture tension, reducing operative time and minimizing suture wear. Ergonomic handles and compatibility with standard orthopedic instruments ensure precise placement, even in minimally invasive surgeries.
Reliable Fixation Strength Throughout Degradation: The anchor's mechanical strength is calibrated to match the healing timeline of soft tissue and bone-maintaining stable fixation during the critical early healing phase (3–6 months) while gradually degrading as the repair site matures. Multiple anti-pull-out ring ridges and full-threaded designs enhance initial bone engagement.

Frequently Asked Questions (FAQ)
Q: What is the composition of the composite material, and how long does it take to fully degrade?
A: The anchor is made of a medical-grade PLGA/HA (poly(lactic-co-glycolic acid)/hydroxyapatite) composite. Full degradation typically occurs within 12–24 months, with the material gradually breaking down into non-toxic byproducts (water and carbon dioxide) that are eliminated by the body. Degradation rate aligns with natural tissue healing, ensuring fixation strength when needed most.
Q: Will the anchor's fixation strength decrease during degradation?
A: No-its mechanical strength is engineered to match the healing timeline. The anchor maintains >80% of initial pull-out strength for the first 3–6 months (critical for soft tissue healing) and gradually degrades as the tendon-bone interface matures. By the time significant degradation begins, the repair site has already achieved stable integration.
Q: Is the Composite Absorbable Anchor System suitable for pediatric or young athletic patients?
A: Yes, it is an excellent choice. Pediatric patients benefit from avoiding secondary implant removal surgery, while young athletes benefit from the anchor's bioactive healing promotion and lack of long-term foreign body interference. The 2.0mm–3.0mm Solid Strike-In variants are ideal for small pediatric joints, and larger sizes support high-stress athletic repairs.
Q: Does the degradable material affect post-operative imaging (e.g., MRI, CT)?
A: No. Unlike metal anchors, the composite material is radiolucent and does not interfere with MRI or CT scans. This allows clinicians to monitor bone healing and soft tissue integration without imaging artifacts, enabling accurate post-operative follow-ups and timely rehabilitation adjustments.
Q: How does this system compare to non-absorbable PEEK anchors in clinical outcomes?
A: Both deliver reliable initial fixation, but the composite absorbable system offers unique advantages: no secondary surgery, reduced long-term implant-related complications, and accelerated tendon-bone healing via bioactive integration. PEEK anchors may be preferred for patients with compromised bone quality or high-risk revision surgeries, while the absorbable system is ideal for most primary repairs, pediatric cases, and patients seeking minimal long-term intervention.
