Annealed Polyvinyl Alcohol Hydrogels for Cartilage Replacement: Effects of Synthesis Parameters on Mechanical Properties
The objective of this paper was to determine the interactive effects of multiple synthesis parameters on annealed PVA hydrogel properties and assess these hydrogels for the application of cartilage replacement. PVA hydrogels were synthesized at two different molecular weight ranges (89–98 kDa and…

A Coaxial Dipole Antenna for Passively Sensing Object Displacement and Deflection for Orthopaedic Applications
A promising approach for monitoring and predicting the course of bone fracture healing is by measuring the mechanical load-sharing between the healing callus and the implanted fixation hardware. Previous technologies have used implantable sensors which require modification to the fixation hardware…

Vivaldi Antennas for Contactless Sensing of Implant Deflections and Stiffness for Orthopaedic Applications
The implementation of novel coaxial dipole antennas has been shown to be a satisfactory diagnostic platform for the prediction of orthopaedic bone fracture healing outcomes. These techniques require mechanical deflection of implanted metallic hardware (i.e., rods and plates), which, when loaded…

A mechanical evaluation of polyvinyl alcohol hydrogels for temporomandibular joint disc replacement
The temporomandibular joint (TMJ) is a bilateral ginglymoarthroidal joint containing a fibrocartilaginous disc which distributes compressive stress and reduces friction on the articulating surfaces of the joint. Initially, conservative treatments can address disorders of the TMJ, but surgical…

Cryopreserved osteochondral allografts: are they similar in biomechanical and histological characteristics at 90 days and 1 year compared with fresh?
Introduction: Large focal chondral and osteochondral lesions can be effectively treated with osteochondral allograft (OCA) transplantation; however, the shelf-life of fresh allograft leads to logistical challenges and subsequent tissue waste. Cryopreservation offers a solution to obstacles…

The Interventricular Septum Is Biomechanically Distinct from the Ventricular Free Walls
The interventricular septum contributes to the pumping function of both ventricles. However, unlike the ventricular wall, its mechanical behavior remains largely unknown. To fill the knowledge gap, this study aims to characterize the biaxial and transmural variation of the mechanical properties of…

Evaluation of lumbar spinal fusion utilizing recombinant human platelet derived growth factor‐B chain homodimer (rhPDGF‐BB) combined with a bovine collagen/β‐tricalcium phosphate (β‐TCP) matrix in an ovine model
Abstract Background context While the clinical effectiveness of recombinant human Platelet Derived Growth Factor‐B chain homodimer combined with collagen and β‐tricalcium phosphate (rhPDGF‐BB + collagen/β‐TCP) treatment for indications involving hindfoot and ankle is well‐established, it is not…

A Large Animal Model for Orthopedic Foot and Ankle Research
Trauma to the soft tissues of the ankle joint distal syndesmosis often leads to syndesmotic instability, resulting in undesired movement of the talus, abnormal pressure distributions, and ultimately arthritis if deterioration progresses without treatment. Historically, syndesmotic injuries have…

Multiscale Contrasts Between the Right and Left Ventricle Biomechanics in Healthy Adult Sheep and Translational Implications
Cardiac biomechanics play a significant role in the progression of structural heart diseases (SHDs). SHDs alter baseline myocardial biomechanics leading to single or bi-ventricular dysfunction. But therapies for left ventricle (LV) failure patients do not always work well for right ventricle (RV)…

Osteoinductive 3D printed scaffold healed 5 cm segmental bone defects in the ovine metatarsus
Abstract Autologous bone grafts are considered the gold standard grafting material for the treatment of nonunion, but in very large bone defects, traditional autograft alone is insufficient to induce repair. Recombinant human bone morphogenetic protein 2 (rhBMP-2) can stimulate bone regeneration…
