Background:

Articular osteochondral defects are challenging to repair due to complex tissue structure and limited chondrocyte proliferation.
Current clinical treatments like microfracture and transplantation show limited efficacy.
Tissue engineering using biomaterials is explored to enhance osteochondral defect repair.

Purpose of the Study:

To review strategies for repairing osteochondral defects using tissue engineering.
To highlight the role of bioinspired gradient scaffolds in mimicking native tissue characteristics.
To predict the clinical translation potential of gradient scaffold-based therapies.

Main Methods:

Review of existing literature on tissue engineering approaches for osteochondral defect repair.
Focus on bioinspired gradient scaffolds that simulate the natural gradient structure of osteochondral tissue.
Analysis of how gradient scaffolds alter microenvironments to induce osteochondrogenesis and interface formation.

Main Results:

Bioinspired gradient scaffolds effectively mimic the anisotropic features of osteochondral matrices.
These scaffolds promote osteochondrogenesis and the formation of osteochondral interfaces compared to homogeneous scaffolds.
Altering microenvironments via gradient scaffolds enhances the repair of osteochondral defects.

Conclusions:

Bioinspired gradient scaffolds represent a significant advancement in tissue engineering for osteochondral defect repair.
These scaffolds offer a more effective approach by replicating the native tissue's gradient characteristics.
Further evaluation is needed to assess the clinical translation prospects and challenges of these advanced biomaterials.
