Our case report highlights the complexity of treating multi-ligament knee injuries in the setting of ipsilateral long bone trauma. We describe the use of the tibial inlay technique for PCL reconstruction in the setting of a tibial shaft fracture treated with an intramedullary nail. We also present a comprehensive treatment algorithm for the treatment of ligamentous knee injuries in the setting of long bone trauma.

In this study, a new hybrid nanoparticle composed of magnesium hydroxide and copper oxide (Mg(OH)/CuO) with an optimized ratio of magnesium (Mg) to copper (Cu) was designed and incorporated into a 3D-printed scaffold made of polycaprolactone (PCL) and gelatin. These hybrid nanostructures (MCNs) were prepared using a green, solvent-free method. Their topography, surface morphology, and structural properties were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS).

Technical hurdles in a culture of epithelial cells include dedifferentiation and loss of function. Biomimetic three-dimensional (3D) cell culture methods can enhance cell culture efficiency. This study introduces an advanced two-layered culture system intended to cultivate epithelial cells as tissue-like layers with the culture of fibroblasts within a 3D environment.

Microtia, along with trauma, represents one of the main causes of external ear malformation. Different clinical techniques were developed for the reconstruction of the auricle, but they all have some drawbacks. This work is focused on the development of an innovative 3D porous scaffold, printed by Fused Deposition Modelling (FDM) and based on laser-scanned images of the healthy contralateral ear of the patient.

Introduction: Acute anterior cruciate ligament (ACL) injuries can be disabling because of prolonged rehabilitation process following surgical reconstructions. Rates of ACL injuries among military service members are close to 10 times greater than the general civilian population, likely because of the operation tempo and the unique physical requirements. Studies debated functional testing requirements for return to sports, but no study investigated the impact of functional training and re-injury rates following ACL reconstruction and their association with functional testing outcomes and time to return to full duty in United States Naval Academy (USNA) Midshipmen.

: Current craniofacial reconstruction surgical methods have limitations because they involve facial deformation. The craniofacial region includes many areas where the mucosa, exposed to air, is closely adjacent to bone, with the maxilla being a prominent example of this structure. Therefore, this study explored whether human neural-crest-derived stem cells (hNTSCs) aid bone and airway mucosal regeneration during craniofacial reconstruction using a rabbit model.
