A biodegradable meniscal screw migrated after arthroscopic surgery, causing knee pain and nerve irritation. This case highlights potential complications of the Clearfix screw system in meniscal refixation.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Knee Arthroscopy

Background:

  • Arthroscopic meniscal refixation aims to repair meniscal tears, promoting knee joint stability.
  • Biodegradable screw systems, like Clearfix, are utilized for meniscal repair, offering an alternative to traditional fixation methods.
  • Proper screw placement is crucial for successful meniscal refixation and to prevent complications.

Observation:

  • A biodegradable Clearfix screw, used for arthroscopic meniscal refixation, migrated from its original position.
  • The screw migration occurred despite adherence to the manufacturer's recommended insertion technique.
  • The migrated screw caused significant medial knee joint pain and irritation of the infrapatellar branch of the saphenous nerve.

Findings:

Related Experiment Videos

  • Meniscal screw migration is a potential complication following arthroscopic meniscal refixation with biodegradable systems.
  • Screw dislocation can lead to iatrogenic nerve irritation and persistent joint pain.
  • This case represents an early analysis of complications associated with the Clearfix meniscal fixation system.

    • Implications:

    • The findings suggest a need for careful patient monitoring after arthroscopic meniscal refixation using biodegradable screws.
    • Further investigation into the biomechanical properties and potential failure modes of biodegradable meniscal fixation devices is warranted.
    • This report underscores the importance of considering screw migration as a differential diagnosis for knee pain post-arthroscopic meniscal repair.
