Summary

This study reports the early degradation of bioabsorbable tacks used in meniscal repair. The tacks showed signs of resorption and were removed during a second-look arthroscopy, indicating a novel observation in knee surgery.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Sports Medicine

Background:

  • Anterior cruciate ligament (ACL) reconstruction is a common orthopedic procedure.
  • Meniscal tears often accompany ACL injuries and require surgical repair.
  • Bioabsorbable tacks are frequently used for meniscal repair due to their presumed safe degradation.

Observation:

  • A dancer with a history of ACL tear underwent arthroscopic ACL reconstruction with concurrent medial meniscus repair using bioabsorbable tacks.
  • Persistent posterior knee pain led to a "second-look" arthroscopy 14 weeks post-reconstruction.
  • The meniscus repair was stable, but the bioabsorbable tacks exhibited motion and were easily removed.

Findings:

  • Inspection revealed that the barbs of the bioabsorbable tacks had been resorbed.

  • This case represents the first reported instance of early tack degradation in meniscal repair.
  • The patient experienced an uneventful recovery with significant improvement in knee flexion.

    • Implications:

    • The findings suggest that bioabsorbable tacks may degrade earlier than anticipated.
    • This early degradation could potentially impact the long-term stability of meniscal repairs.
    • Further research is warranted to understand the degradation kinetics and clinical significance of bioabsorbable tack materials in orthopedic surgery.
