Background: To harvest any flap on the lateral circumflex femoral artery (LCFA) including tensor fasciae latae (TFL) muscle, a precise description of the vascular anatomy is required. There have been conflicting reports of the vascular supply of TFL and its overlying skin. The objective of this study was to evaluate the anatomy of the TFL muscle according to the location, origin, type, caliber, and length of vessels that supply the muscle.
Methods: This study was performed on human cadavers ( = 16 thighs) that were injected with a mixture of lead oxide and gelatin through the femoral artery. Whole body computed tomography scans were performed. Three-dimensional images of the arterial anatomy were created using Materialise Interactive Medical Image Control Software (MIMICS). Anatomical dissection of all cadaver thighs was performed to visualize the arterial blood supply of the muscle and its regional perforators.
Results: Sixteen thighs were included in the study. The main arterial supply of the TFL muscle was in all cases, the ascending branch of the LCFA (LCFA-asc) artery. The mean external diameter of the LCFA-asc artery was 2.7 mm ± 0.4 and the mean length was 3.6 cm ± 0.6. The distance from the anterior superior iliac spine to point where the vascular pedicle reaches the muscle ranged from 6.7 to 10.2 cm. The average number of cutaneous perforators was 10.9 ± 4. There were musculocutaneous perforators in all of our dissections ( = 16) and 14 of our specimens had septocutaneous perforators.
Conclusion: The main vascular supply to the TFL muscle is the ascending branch of the LCFA, which also gives rise to septocutaneous and musculocutaneous perforators. MIMICS provides excellent three-dimensional anatomical information about the vascular supply of the TFL.

Background: Hip osteoarthritis patients display higher levels of fatty infiltration (FI) in the gluteus minimus (GM) compared to other hip muscles. We investigated specific histological factors such as fiber type composition and collagen deposition, and functional outcomes like muscle strength and activation associated with FI in these patients.
Methods: In twelve men (67 ± 6 y) undergoing total hip replacement (THR), hip and knee muscle strength and activation (electromyography, EMG) were assessed bilaterally.

This study aimed to evaluate the muscle activation ratio of hip and knee during hip-focused exercises. Eleven active university students performed 13 hip-focused exercises frequently used in the treatment of knee disorders. The average sEMG amplitude of tensor fasciae latae (TFL), gluteus medius (GMed), gluteus maximus (GMax), adductor longus (AL), vastus medialis (VM), vastus lateralis (VL), and GMed/AL, GMax/AL, and VL/VM ratios were determined.

Background: One key focus in the literature is the need to better understand how males and females perform neuromuscular control, which requires consideration of muscle morphology, as it may change neural drive during force production. Although previous studies focused on muscles around the knee and ankle, it is crucial to explore the behavior of other muscles, such as the hip abductors, since many lower limb conditions more common in females have been associated with alterations in hip muscles.
Research Questions: Are electromyography (EMG) variables (amplitude and low- and high frequency bands) of hip abductors during submaximal isometric tasks different between males and females? How is muscle size associated with EMG responses during these tasks?
Methods: Thirty-six participants (males, n = 18; females, n = 18) had muscle and subcutaneous thickness of gluteus medius (GMed) and tensor fascia latae (TFL) measured.
