The Ligament Augmentation and Reconstruction System (LARS) is a prosthetic device used to support knee ligaments severed due to injury. The role of LARS in supporting the knee ligaments is to take over the position of the natural ligaments that have been severed, binding the thigh bone and shin bone. LARS is made from polyethylene terephthalate (PET) material, commonly used in industry. LARS is a prosthetic product widely used to heal ligament injuries. However, despite its everyday use, no one has confirmed whether LARS can support a severed ligament. There has never been a study analyzing this tool, even from the company that makes LARS. They only state that LARS is safe and suitable for healing ligament injuries. Therefore, a LARS analysis is needed to convince the public that the tool is safe. This study analyzed the stress distribution in LARS during the standing-to-squatting condition. The results show an uneven stress distribution between the LARS inside the femur and other parts of the LARS. However, the stress distribution is still in a safe condition that does not directly reduce the strength of the LARS.

The tibia is a common site for stress fractures, which are believed to develop from microdamage accumulation to repetitive sub-yield strains. There is a need to understand how the tibia is loaded in vivo to understand how stress fractures develop and design exercises to build a more robust bone. Here, we use subject-specific, muscle-driven, finite element simulations of 11 basketball players to calculate strain and strain rate distributions at the midshaft and distal tibia during six activities: walking, sprinting, lateral cut, jumping after landing, changing direction from forward-to-backward sprinting, and changing direction while side shuffling. Maximum compressive strains were at least double maximum tensile microstrains (mu) during the stance phase of all activities. Sprinting and lateral cut had the highest compressive (-2773 +/- 934 mu) and -2266 +/-815 mu, respectively) and tensile (999 +/- 381 mu and 907 +/- 261 mu, respectively) strains. These activities also had the highest strains rates (peak compressive strain rate = 46237 +/- 38217 mu/s and 41510 +/- 17245 mu/s, respectively). Compressive strains principally occurred in the posterior tibia for all activities; however, tensile strain location varied. In particular, activities involving a change in direction increased tensile loads in the anterior tibia. These observations may guide preventative and management strategies for tibial stress fractures. In terms of prevention, the strain distributions suggest individuals should perform activities involving changes in direction during growth to adapt different parts of the tibia and develop a more fatigue resistant bone. In terms of management, the greater strain and strain rates during sprinting than jumping suggests jumping activities may be commenced earlier than full pace running. The greater anterior tensile strains during changes in direction suggest introduction of these types of activities should be delayed during recovery from an anterior tibial stress fractures, which have a high-risk of healing complications.

“…have been introduced, allowing the field of tissue engineering to advance quickly. Advances in molecular and cellular biology, as well as, engineering breakthroughs such as micro and nano systems and additive manufacturing, computational analysis and simulations significantly extended the concept of tissue engineering [23][24][25][26]. Currently, even though some therapies have received approval or clearance from Food and Drug Administration (FDA) and are commercially available, many challenges remain to be solved in order to serve effectively the wide range of patient needs.…”

Bone tissue engineering (BTE) as a modern and more effective treatment for bone defects has recently received lots of attention. One of the pivotal parts of BTE is the "scaffold", which functions as an indwelling carrier of cells and additives, as well as, providing a foundation for cell growth and eventually forming new, native-like bone. Up to now, many methods and materials have been employed to manufacture bone scaffolds. This review focuses on providing both basic knowledge of BTE as well as possible methods of scaffold manufacturing. We categorize the fabrication methods into; current conventional methods and newly emerging additive manufacturing (AM) techniques. The fundamental, capabilities and limitations of each technique is investigated, and the latest achievements are presented.
