Background:

Osteoarthritis (OA) is a leading cause of global disability, characterized by cartilage and subchondral bone damage.
The osteochondral interface, crucial for joint function, presents complex anatomical and biomechanical challenges for regeneration.
Current clinical repair methods face difficulties in restoring this intricate tissue junction.

Purpose of the Study:

To review the anatomical, microstructural, and biomechanical properties of the osteochondral interface.
To summarize recent advancements in tissue engineering strategies for osteochondral regeneration.
To highlight the importance of biomimetic scaffolds and biological factor regulation in addressing osteochondral defects.

Main Methods:

Literature review of anatomical composition and biomechanical properties of the osteochondral interface.
Analysis of current tissue engineering approaches for osteochondral defect repair.
Synthesis of research on biomimetic scaffold fabrication and biological factor modulation.

Main Results:

The osteochondral interface exhibits unique cellular and biomechanical characteristics.
Successful regeneration necessitates a coordinated approach involving cells, materials, and biological/physical factors.
Biomimetic scaffolds and controlled biological factor delivery are key areas of recent progress.

Conclusions:

Regenerating the osteochondral interface is complex, requiring a multidisciplinary tissue engineering approach.
Advancements in biomimetic scaffolds and biological factor regulation show promise for treating osteochondral defects.
Further research is needed to fully restore the native osteochondral structure and function.
