Summary: Originating from biomechanics, Fung's model of quasi-linear viscoelasticity (QLV) is a popular constitutive theory used to compute the time-dependent relationship between stress and deformation in soft solids. This study discusses the thermodynamic consistency of the QLV model incorporating a single scalar relaxation function, highlighting similarities with other internal variable models. The dissipative features of compressible QLV materials are illustrated in simple tension.

Summary: This systematic review revealed that the origin of the MPFL on the distal femur lies distal to the medial distal femoral physis in skeletally immature participants. The mean distance was approximately 7 mm, but this can vary in the literature due to study design and patient characteristics.

Summary: This study aims to compare the clinical and biomechanical outcomes of dynamic versus static medial patellofemoral ligament (MPFL) reconstruction. Using a randomized clinical trial design, patients with recurrent patella dislocation will be recruited and randomly assigned to different reconstruction techniques, with long-term follow-up. The study will provide evidence to support orthopedic surgeons in their decision-making for surgical techniques.

Summary: This study confirms the importance of optimal anatomical femoral insertion in MPFL reconstruction and finds a significant positive correlation between graft positioning and clinical outcomes. However, no significant correlation is found between anatomical insertion and the development of patellofemoral osteoarthritis.

Summary: This study aimed to identify the causes of failure of previous medial patellofemoral ligament reconstruction (MPFL-R) and report the surgical techniques available for MPFL revision surgery. The most common indications for revision surgery were malpositioning of the femoral tunnel, unaddressed trochlear dysplasia, and patellar fracture. Promising outcomes have been reported for revision MPFL-R, although larger prospective studies are needed for optimal surgical management.

Summary: MPFL reconstruction is a reliable technique for the treatment of patellofemoral instability. The SchOttle point remains the mainstream method for determining the femoral attachment, with the patellar attachment for single-bundle located at the junction of the proximal one third and the distal two third of the longitudinal axis of the patella. For double-bundles, one is located at the proximal one third of the medial patellar edge and another is at the center of the patellar edge. Adjusting the graft tension during surgery is crucial.

Summary: This study assessed the outcomes of medial patellofemoral ligament (MPFL) reconstruction using allograft tendon in skeletally immature patients. It found that the procedure was safe and effective for treating patellar instability, regardless of patellar height and trochlear dysplasia. The study also identified a decrease in failure rates when MPFL reconstruction was performed together with a tibial tubercle osteotomy.

Summary: This study compares the accuracy and clinical efficacy of determining the femoral tunnel point using a 3D-printed individualized navigation template versus fluoroscopic guidance in double-bundle isometric MPFL reconstruction. The results show that the use of the individualized navigation template allows for more accurate determination of the femoral tunnel point and higher knee function scores in the early postoperative period.

Summary: This study investigates the structure and correlations between structure, mechanical, and biological properties of gelatin-based materials. Gelatin electro-spun materials have higher content of ordered structure compared to gelatin casted films, which may be attributed to the random coil - alpha-helix transition during electrospinning. The presence of cross linker (GPTMS) decreases the ordered structures in gelatin casted films, while it does not affect the percentage of ordered structure in electrospun samples. The presence of keratin in gelatin/keratin electrospun biomaterials decreases alpha-helix content and promotes the conversion from antiparallel to parallel beta-sheet.

Summary: Each year, thousands of patients face life-threatening ear, nose, and throat disorders, such as tracheal stenosis, or conditions that affect their psychosocial well-being, such as microtia. Tissue engineering offers an exciting alternative by creating bioartificial constructs using three-dimensional scaffolds and human cells that can grow and develop. Bioprinting technologies, which utilize additive manufacturing, are particularly useful in addressing the complex geometries of ear, nose, and throat, allowing for the creation of patient-specific scaffolds with high design flexibility and repeatability.

Summary: Bone tissue engineering is a promising strategy for treating bone-related disorders. A novel polymeric blend of PLLA, PCL, and PHBV was explored to address the trade-off between mechanical properties and bioactivity. The blend was enriched with nano-HA and Sr-nano-HA to enhance its osteogenic potential.

Summary: Bioprinting is a rapidly growing field, and there is a need for an automatic tool to assist researchers in analyzing literature and accelerating development. In this study, an automatic keyword annotation model based on NLP techniques is proposed. The model utilizes abstracts and author keywords to train a composite model that can classify keywords into manufacturing techniques, employed materials, or applications. The annotated keywords are then used to generate a lexicon and extract relevant information. This approach can serve as a basis for automated analysis of bioprinting literature.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
