Which tendon graft to choose for anatomical ligament reconstruction in chronic lateral ankle instability? A biomechanical study

Purpose: To evaluate the mechanical properties of different tendon grafts used for reconstructing the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL), aiding optimal graft selection. 

Summary:

• This cadaveric biomechanical study evaluated the mechanical properties of various tendon grafts used for anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) reconstruction. 
• All tendons tested, including gracilis, peroneus longus, anterior tibialis, posterior tibialis, and semitendinosus, demonstrated a higher mean load to failure compared to the native ATFL and CFL. 

JRF Takeaways: This study reinforces the suitability of tendon allografts for ATFL and CFL reconstruction. All tendon types used in pre-sutured constructs demonstrated biomechanical properties exceeding those of native ligaments. Pre-sutured tendons offer surgeons a reliable, time-saving option in the operating room.
