Abstract

There is an unmet need for new techniques and methods of healing critical size tissue defects, by further reduction of invasiveness in implant, cell and tissue-based surgery. This paper presents the development of a new regenerative medicine that combines 3D bio-printing and robotic-assisted minimally invasive surgery techniques to meet this need.

We investigated the feasibility of Remote Centre of Motion (RCM) and viscous material extrusion 3D printing. A hypothetical, intra-articular, regenerative medicine-based treatment technique for focal cartilage defects of the knee was used as a potential example of the application of 3D printing in vivo.

The results of this study suggest, that RCM mechanism is feasible with viscous material extrusion 3D printing processes, without a major trade-off in imprint quality.

The achieved printing accuracy at an average dimensional error of 0.06±0.14mm in this new modality of 3D printing is comparable to those described in literature for other types of bioprinting.

Robotic assisted 3D bio-printing demonstrated here is a viable option for focal cartilage defect restoration.
