From muscle fibres to muscle gears: how dynamic fascicle orientation and shape change impact skeletal muscle function

Biological Reviews, EarlyView.
ABSTRACT Skeletal muscle architectural design strongly affects force‐generating capacity and excursion range, and its functional importance to animal and human movement is well founded. Traditionally, this ‘structure–function relation’ has been inferred from architecture measurements with muscles at rest (from anatomical dissections or medical imaging ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

Surface electromyographic analysis of the common strengthening exercises for the vastus medialis and vastus lateralis muscles

, 2017
This study was done to identify strengthening exercises that elicit the greatest level of EMG activity in the vastus medialis and vastus lateralis muscles. Strengthening exercises are important to improve muscle power.

Rectus femoris tendon morphometry and practical landmarks for harvesting: A cadaveric study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To perform a qualitative and quantitative cadaveric analysis of the rectus femoris (RF) tendon to determine its suitability as a standalone autograft for knee ligament reconstruction and to identify consistent anatomical landmarks for safe and reproducible harvest.

Impact of hamstring versus quadriceps tendon graft on thigh muscle strength and surface electromyography activity after anterior cruciate ligament reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare quadriceps tendon (QT) and hamstring tendon (HT) autografts regarding isometric thigh muscle strength, surface electromyography (sEMG) activity and clinical outcomes following anterior cruciate ligament reconstruction (ACLR).

Preoperative and postoperative risk factors for arthrogenic muscle inhibition in anterior cruciate ligament reconstruction: A retrospective study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose This study aimed to identify preoperative and postoperative risk factors associated with the development of arthrogenic muscle inhibition (AMI) in patients undergoing anterior cruciate ligament reconstruction (ACLR). The hypothesis was that distinct risk factors contribute to the occurrence of preoperative and postoperative AMI ...

Quadriceps malalignment is strongly associated with recurrent patellofemoral instability in native knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral instability (PFI) has been associated with multiple anatomical risk factors. The recent development of accurate quadriceps muscle measurements using three‐dimensional imaging techniques have demonstrated that quadriceps alignment is highly variable and frequently leads to a lateralised force vector on the patella.

PATELLECTOMY WITH VASTUS MEDIALIS OBLIQUUS ADVANCEMENT FOR COMMINUTED PATELLAR FRACTURES

, 1997
We have compared the results of simple patellectomy (group A, n = 16) and patellectomy with advancement of the vastus medialis obliquus (group B, n = 12) in a prospective, randomised trial, with a minimum follow-up of three years.
