  Three-dimensional printer (3DP) (Z-Corp) is a solid freeform fabrication system capable of generating sub-millimeter physical features required for tissue engineering scaffolds. By using plaster composite materials, 3DP can fabricate a universal porogen which can be injected with a wide range of high melting temperature biomaterials. Here we report results… (More)
  Increasing evidences show that subchondral bone may play a significant role in the repair or progression of cartilage damage in situ. However, the exact change of subchondral bone during osteochondral repair is still poorly understood. In this paper, biphasic osteochondral composite scaffolds were fabricated by 3D printing technology using PEG hydrogel and… (More)
  Combinatorial material synthesis is a powerful approach for creating composite material libraries for the high-throughput screening of cell-material interactions. Although current combinatorial screening platforms have been tremendously successful in identifying target (termed "hit") materials from composite material libraries, new material synthesis… (More)

  Porous beta-tricalcium phosphate (beta-TCP) scaffolds with controlled architecture and improved mechanical properties were fabricated by combining the gel-casting and rapid prototyping techniques. The pore morphology, size, and distribution of the beta-TCP scaffolds were characterized using a scanning electron microscope. The porosity of the resulting… (More)
  Interface integration between chondral phase and osseous phase is crucial in engineered osteochondral scaffolds. However, the integration was poorly understood and commonly failed to meet the need of osteochondral scaffolds. In this paper, a biphasic polyethylene glycol (PEG)/β-tricalcium phosphate (β-TCP) scaffold with enhanced interfacial integration was… (More)

  Purpose – This paper aims to describe computer-aided design and rapid prototyping (RP) systems for the preoperative planning and fabrication of custom-made implant. Design/methodology/approach – A patient with mandible defect underwent reconstruction using custom-made implant. 3D models of the patient's skull are generated based on computed tomography image… (More)

  INTRODUCTION Long bone fracture is common in traumatic osteopathic patients. Good reduction is beneficial for bone healing, preventing the complications such as delayed union, nonunion, malunion, but is hard to achieve. Repeated attempts during the surgery would increase the operation time, cause new damage to the fracture site and excessive exposure to… (More)

  Loss of ligament graft tension in early postoperative stages following anterior cruciate ligament (ACL) reconstruction can come from a variety of factors, with slow graft integration to bone being widely viewed as a chief culprit. Toward an off-the-shelf ACL graft that can rapidly integrate to host tissue, we have developed a silk-based ACL graft combined… (More)
  Good reduction and appropriate fixation are critical for long bone fractures, however, neither has been addressed satisfactorily. Robotic and navigation techniques can help improve the reduction accuracy. However, their clinical applications are limited by high cost and complexity in operation. The aim of this study was to discuss the feasibility of a… (More)

  Many biological processes are regulated by gradients of bioactive chemicals. Thus, the generation of materials with embedded chemical gradients may be beneficial for understanding biological phenomena and generating tissue-mimetic constructs. Here we describe a simple and versatile method to rapidly generate materials containing centimeter-long gradients of… (More)
