Advancements in Cartilage Tissue Engineering: A Focused Review.

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Orthopedics

Background:

• Osteoarthritis (OA) is a degenerative joint disease characterized by articular cartilage breakdown.
• Current OA treatments primarily manage symptoms, not disease progression.
• Cartilage tissue engineering aims to regenerate cartilage and restore joint function.

Purpose of the Study:

• To review advancements in cartilage tissue-engineered constructs for OA over the past decade.
• To highlight biomaterials and fabrication techniques used in cartilage tissue engineering.
• To identify challenges and future directions in the field.

Main Methods:

• Review of preclinical studies on cartilage tissue-engineered constructs.
• Analysis of constructs utilizing natural, synthetic, and composite biomaterials.
• Evaluation of conventional and advanced fabrication techniques.

Main Results:

• Tissue-engineered constructs show preclinical efficacy in promoting cartilage regeneration.
• Diverse biomaterials and fabrication methods are employed for construct development.
• Significant progress has been made in developing viable therapeutic approaches for OA.

Conclusions:

• Cartilage tissue engineering holds significant potential as a therapeutic strategy for osteoarthritis.
• Overcoming challenges in replicating native cartilage anatomy is crucial for clinical translation.
• Collaborative research is essential to advance cartilage tissue engineering for OA treatment.
