“…In developing translational biofabrication applications, large 3D constructs generated at a clinically relevant scale have further advanced the clinical potential of bioprinted implants. While most approaches continue to apply acellular 3D printing strategies [ 98 , 99 ], there is growing interest in printing skeletal stem cells for the functionalisation of scaffolds aiming for the repair of large bone defects. Recently, critical sized implants comprising of cells were fabricated via an automated assembly process [ 100 ].…”

Recent advances in regenerative medicine have confirmed the potential to manufacture viable and effective tissue engineering 3D constructs comprising living cells for tissue repair and augmentation. Cell printing has shown promising potential in cell patterning in a number of studies enabling stem cells to be precisely deposited as a blueprint for tissue regeneration guidance. Such manufacturing techniques, however, face a number of challenges including; (i) post-printing cell damage, (ii) proliferation impairment and, (iii) poor or excessive final cell density deposition. The use of hydrogels offers one approach to address these issues given the ability to tune these biomaterials and subsequent application as vectors capable of delivering cell populations and as extrusion pastes. While stem cell-laden hydrogel 3D constructs have been widely established in vitro , clinical relevance, evidenced by in vivo long-term efficacy and clinical application, remains to be demonstrated. This review explores the central features of cell printing, cell-hydrogel properties and cell-biomaterial interactions together with the current advances and challenges in stem cell printing. A key focus is the translational hurdles to clinical application and how in vivo research can reshape and inform cell printing applications for an ageing population.

“…[ 60 ] They are also biocompatible (Table 1). [ 61 ] Similarly to other polymers, they are radiolucent, [ 62 ] which makes them easy to image and compatible with histological imaging (Table 1). However, they are harder to print with extrusion machines because their melting point is very high (300–360 °C as indicated in polymerdatabase.com) so the machines have to be thermally isolated and equipped with a high power heater.…”

Additive manufacturing (AM) allows the fabrication of customized bone scaffolds in terms of shape, pore size, material type, and mechanical properties. Combined with the possibility to obtain a precise 3D image of the bone defects using computed tomography or magnetic resonance imaging, it is now possible to manufacture implants for patient‐specific bone regeneration. This paper reviews the state‐of‐the‐art of the different materials and AM techniques used for the fabrication of 3D‐printed scaffolds in the field of bone tissue engineering. Their advantages and drawbacks are highlighted. For materials, specific criteria, are extracted from a literature study: biomimetism to native bone, mechanical properties, biodegradability, ability to be imaged (implantation and follow‐up period), histological performances, and sterilization process. AM techniques can be classified in three major categories: extrusion‐based, powder‐based, and vat photopolymerization. Their price, ease of use, and space requirement are analyzed. Different combinations of materials/AM techniques appear to be the most relevant depending on the targeted clinical applications (implantation site, presence of mechanical constraints, temporary or permanent implant). Finally, some barriers impeding the translation to human clinics are identified, notably the sterilization process.

“…24 In a recent case report, a 3D-printed polyetheretherketone scapular prosthesis was combined with shoulder replacement for an accurate reconstruction after resection of a benign fibrous histiocytosis of the scapula. 25 Due to the poor soft tissue contrast of CT, many clinical practices do not depend on radiographic or CT findings to determine the integrity of the rotator cuff tendons. Instead, MRI and ultrasound are implemented as part of the preoperative planning to differentiate between full-thickness tendon tearing and an intact rotator cuff and to assess directly the severity of partial-thickness tendon tears.…”

Over the last decade, the number of shoulder arthroplasty procedures has been increasing and evolving. The types of prostheses have also been evolving, and familiarity with the various design types will assist in postoperative assessment for hardware complications. New preoperative planning tools are available that have radically changed the protocol of preoperative image studies performed. This article reviews the main types of shoulder prostheses, discusses radiologic studies required before surgery, and describes the common complications of shoulder arthroplasty.
