A novel core biopsy technique for anterior cruciate ligament preserves ligament structural integrity : a porcine study

Abstract
The objective of this study was to validate a new technique to safely obtain core biopsy specimens of the anterior cruciate ligament (ACL) without jeopardizing the ACL's biomechanical properties. Methods: Eleven pairs of fresh porcine femur-ACL-tibia complexes were tested in a loading frame. The ACL of one knee was biopsied using a spring-loaded core biopsy device, whereas the contralateral ACL was tested as the control. Biomechanical properties of the biopsied and control ACLs were compared. Results: The ultimate load to failure was 1,202 N +/- 171.1 N and 1,193 N +/- 228.7 N (P = .8984) for biopsied and non-biopsied ACLs, respectively. No significant differences were noted for maximal elongation at failure, maximal strain, absorbed energy, and stiffness between biopsied and non-biopsied ACLs. Conclusions: The results of this study indicate that a new ACL core biopsy technique can be performed while preserving the ligament's structural integrity. Clinical Relevance: The presented core biopsy technique could be regarded as a dedicated tool to elucidate the poorly understood (patho) biological processes occurring in both the native and reconstructed ACLs.
