AI Article Synopsis
- The posterolateral corner (PLC) of the knee is essential for lower extremity function, consisting of complex ligaments and muscles that help resist specific movements like varus and external rotation.
- Injuries to the PLC can lead to significant physical disability, impacting daily activities and sports.
- The paper is divided into two parts: one detailing the intricate anatomy of the PLC and the other examining how this structure's anatomy affects its biomechanics.
Article Abstract
The posterolateral corner (PLC) of the knee is a critical element for a functional lower extremity. It consists of an array of complex ligamentous and musculotendinous structures. The primary function of the PLC is to resist varus and external rotation and posterior translation of the tibia. Injuries to these structures can cause significant disability and compromise activities of daily living and work, recreational, and sporting activities. A thorough understanding of the complex anatomy and biomechanics of the PLC will aid the clinician in this challenging diagnostic and therapeutic problem. The first section of this paper describes the anatomy of the PLC of the knee focusing on the intricate insertion sites of the individual structures. The second section discusses how the anatomy influences the biomechanics of the PLC.

The biomechanical implications of lacunar and perilacunar microarchitecture on microdamage accumulation in cortical bone.

: This study aimed to explore how the microarchitectural features of lacunae and perilacunar zones impact the biomechanics of microdamage accumulation in cortical bone, crucial for understanding bone disorders' pathogenesis and developing preventive measures. : Utilizing the phase field finite element method, the study analyzed three bone unit models with varying microarchitecture: one without lacunae, one with lacunae and one including perilacunar zones, to assess their effects on cortical bone's biomechanical properties. : The presence of lacunae was found to increase microcrack initiation risk, acting as nucleation points and accelerating microcrack propagation.

Although the role of low-level laser therapy (LLLT) and human adipose-derived stem cells (hADSC) in accelerating diabetic wound healing has been proven, their synergistic effect is still debated. This study aimed to evaluate the individual and combined effects of LLLT and hADSC on wound healing and on biomechanical parameters in type 2 diabetic rabbits. In this experimental study, 40 rabbits with type 2 diabetes (induced by streptozotocin (STZ)) were included.

Introduction: Sacroiliac joint (SIJ) dislocations, particularly pure SIJ dislocations without associated fractures, represent a rare and complex subset of pelvic ring injuries. Given the intricate pelvic anatomy and the need to achieve both stability and functional recovery, the optimal surgical management for these injuries remains a topic of debate. This systematic review aims to evaluate the various surgical techniques employed in treating this rare and challenging injury and assess associated clinical outcomes and complications.

Background: Transfemoral osseointegrated prostheses, like other uncemented prostheses experience the risk of aseptic loosening and post-operative periprosthetic fractures, with an incidence between 3% and 30%. To date, however, osseointegrated off-the-shelf prostheses are manufactured in a limited number of sizes, and some patients do not meet the strict eligibility criteria of commercial devices. A customized osseointegrated stem was developed and a pre-clinical in vitro investigation of the stem was performed, to evaluate its biomechanical performance.

: Toe flexor strength (TFS) has been determined to evaluate the toe flexor muscle function. However, it is unclear how strength and size relationships of toe flexor muscles vary depending on the toes intended for force production. We aimed to clarify this by examining the relationship between TFS and toe flexor muscle size, and hypothesized TFS produced by all toes (TFS-All), the great toe (TFS-Great) and lesser toes (TFS-Lesser) would be specifically associated with the size of the muscles specialized in each corresponding toe flexion.
