Osteochondral tissue engineering with biphasic scaffold: current strategies and techniques.

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Orthopedic Surgery

Background:

• Osteoarthritis (OA) management is challenging due to limited articular cartilage healing capacity.
• Osteochondral lesions require innovative treatment strategies beyond current clinical options.
• Tissue engineering and cell-based technologies present new therapeutic avenues.

Purpose of the Study:

• To review the feasibility of tissue-engineered biphasic scaffolds for osteochondral repair.
• To highlight recent advancements in scaffold design and fabrication for tissue regeneration.
• To discuss key components including cells, growth factors, and materials for osteochondral defect repair.

Main Methods:

• Focus on preclinical large animal studies and clinically relevant trials.
• Analysis of scaffold design, fabrication, and material selection.
• Review of cell sources and growth factor applications in osteochondral repair.

Main Results:

• Biphasic scaffolds show potential for mimicking the native osteochondral complex.
• Recent studies demonstrate progress in tissue regeneration techniques for osteochondral defects.
• Large animal studies and clinical trials provide insights into therapeutic efficacy.

Conclusions:

• Tissue-engineered biphasic scaffolds represent a viable strategy for osteochondral repair.
• Continued research and clinical translation are crucial for treating OA patients.
