Main Methods:

• Review of existing literature on joint tissue biology and organoid development.
• Analysis of 3D bioprinting methodologies applicable to cartilage repair.
• Exploration of strategies for designing physiologically relevant joint organoids.

Main Results:

• 3D bioprinting enables precise control over joint organoid design, including shape, structure, and cellular composition.
• This technology can mimic natural joint tissue properties and biological cues.
• The review outlines key procedures and strategies for constructing these advanced organoids.

Conclusions:

• 3D bioprinting offers a promising avenue for creating sophisticated joint organoids.
• These organoids can serve as models for studying joint diseases and testing treatments.
• Future applications hold potential for advancing cartilage repair and joint regeneration therapies.
