PEEK SCREW in acl surgery

Great question — the choice between PEEK screws and bioabsorbable screws in ACL reconstruction depends on multiple factors, including surgeon preference, patient needs, and long-term goals. Here's a comparison to help you understand: PEEK Screws (Polyetheretherketone) Pros: Biocompatible & Inert: Doesn’t interfere with imaging (MRI-compatible). Strong and Durable: Maintains fixation strength over time. No degradation: Stays in the body without breaking down. Easy for revision surgery: No inflammatory reaction or cyst formation, unlike some bioabsorbables. Cons: Permanent Implant: Remains in the body indefinitely unless removed. Cost: Often more expensive than metal or bioabsorbable options. Bioabsorbable Screws Pros: Degrade Over Time: Eliminates the need for hardware removal. Bone Healing Integration: Theoretically allows bone to grow into the space. No permanent foreign body. Cons: Risk of Inflammation: Breakdown products can sometimes cause a reaction. Loss of Strength: As they degrade, strength diminishes. Cyst Formation: Some materials can cause tunnel widening or cysts. Conclusion: PEEK screws are generally preferred in high-demand patients or where long-term strength and stability are crucial. They also perform better in terms of revision surgery and cause fewer complications like tunnel widening or synovitis. However, in pediatric or low-demand cases, bioabsorbable screws might still be considered to avoid a permanent implant.
