Advanced Gene Therapy Strategies for the Repair of ACL Injuries.

Area of Science:

• Orthopedics
• Regenerative Medicine
• Biotechnology

Background:

• Anterior cruciate ligament (ACL) injuries are common, necessitating surgical repair due to the ligament's limited intrinsic healing capabilities.
• Current surgical outcomes for ACL repair are often suboptimal, lacking long-term efficacy, completeness, and safety.
• Gene therapy presents a potential strategy to improve ACL healing by delivering therapeutic genetic sequences.

Purpose of the Study:

• To review the potential of gene therapy for enhancing anterior cruciate ligament (ACL) repair.
• To discuss the challenges hindering the clinical translation of gene therapy for ACL injuries.
• To highlight the advancements in biomaterial-guided gene therapy for improved ACL repair.

Main Methods:

• Review of existing literature on gene therapy applications for ACL repair in various experimental models (in vitro, in situ, in vivo).
• Analysis of physiological barriers and host immune responses impacting gene therapy efficacy.
• Exploration of biomaterial-guided gene therapy as an advanced delivery system.

Main Results:

• Gene therapy has demonstrated workability in experimental models for enhancing ACL repair processes.
• Significant hurdles remain for clinical application, including biological barriers and immune reactions.
• Biomaterial-guided gene therapy shows promise for protecting gene vectors and improving delivery.

Conclusions:

• Gene therapy holds significant potential for durable and effective anterior cruciate ligament (ACL) repair.
• Overcoming physiological and immunological challenges is crucial for successful clinical translation.
• Biomaterial-guided approaches represent a key advancement in optimizing gene therapy for future ACL injury treatment.
