[Application of internal brace ligament augmentation technology in repair and reconstruction of cruciate ligament injuries].

OBJECTIVE

To review the application progress of internal brace ligament augmentation (IBLA) technology in the repair and reconstruction of anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injuries, and to clarify the development trends of IBLA technology.

METHODS

A comprehensive review of recent domestic and international in vitro and in vivo biomechanical studies, animal experiments, and clinical research on IBLA technology was conducted. The effects of this technology on postoperative biomechanics, histological changes, and clinical outcomes following ACL and PCL repair and reconstruction were analyzed and summarized.

RESULTS

IBLA technology provides enhanced knee stability in the early postoperative period after ACL and PCL repair and reconstruction. It promotes healing at the ligament injury site and increases the biomechanical strength of tendon grafts, thereby reducing postoperative failure rates. IBLA demonstrates good histocompatibility in vivo. Clinical follow-up shows that IBLA improves early postoperative knee stability, range of motion, and functional scores. Patients undergoing rapid rehabilitation achieve more satisfactory outcomes, with no reported serious complications.

CONCLUSION

The combination of IBLA with ACL and PCL repair and reconstruction promotes rapid early postoperative recovery and shows promising application prospects. However, further optimization of IBLA material properties and related surgical techniques is needed. Additionally, the long-term effectiveness, structural remodeling of the grafts and repaired ligaments, and the underlying biomechanical functional mechanisms require further clarification.
