Agent-based model provides insight into the mechanisms behind failed regeneration following volumetric muscle loss injury.

PLoS Comput Biol 2021 May 10;17(5):e1008937. Epub 2021 May 10.

Biomedical Engineering, University of Virginia, Charlottesville, Virginia, United States of America.

Skeletal muscle possesses a remarkable capacity for repair and regeneration following a variety of injuries. When successful, this highly orchestrated regenerative process requires the contribution of several muscle resident cell populations including satellite stem cells (SSCs), fibroblasts, macrophages and vascular cells. However, volumetric muscle loss injuries (VML) involve simultaneous destruction of multiple tissue components (e. Read More

Effects of a neuromuscular training program using external focus attention cues in male athletes with anterior cruciate ligament reconstruction: a randomized clinical trial.

BMC Sports Sci Med Rehabil 2021 May 8;13(1):49. Epub 2021 May 8.

Orthopedic Department Chair, Akhtar Orthopedic Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: Athletes who have undergone anterior cruciate ligament (ACL) reconstruction often exhibit persistent altered biomechanics and impaired function. Neuromuscular training programs appear to be effective for reducing high-risk landing mechanics and preventing primary ACL injuries; however, there have been few attempts to examine their effects in athletes who have undergone ACL reconstruction. The purpose of our study was to examine the effects of a neuromuscular training program that emphasizes external focus of attention cuing on biomechanics, knee proprioception, and patient-reported function in athletes who had undergone ACL reconstruction and completed conventional post-operative rehabilitation.

Loading mechanisms of the anterior cruciate ligament.

Sports Biomech 2021 May 7:1-29. Epub 2021 May 7.

Department of Orthopaedic Surgery, University of Michigan, Ann Arbor, MI, USA.

This review identifies the three-dimensional knee loads that have the highest risk of injuring the anterior cruciate ligament (ACL) in the athlete. It is the combination of the muscular resistance to a large knee flexion moment, an external reaction force generating knee compression, an internal tibial torque, and a knee abduction moment during a single-leg athletic manoeuvre such as landing from a jump, abruptly changing direction, or rapidly decelerating that results in the greatest ACL loads. While there is consensus that an anterior tibial shear force is the primary ACL loading mechanism, controversy exists regarding the secondary order of importance of transverse-plane and frontal-plane loading in ACL injury scenarios.

Lisfranc injuries in adolescents: A case report and literature review.

Foot (Edinb) 2021 Apr 18;47:101812. Epub 2021 Apr 18.

Section of Orthopedics and Trauma Surgery, Ospedale Salvini, viale Forlanini 95, 20024 Garbagnate Milanese, Milano, Italy.

Lisfranc injuries result if bones or ligaments that support the midfoot are torn. In children and adolescents these injuries are not only rare, but are also similar to adult Lisfranc injuries, in that they are often mistaken especially if the injury is a result of a straightforward twist and fall. The goal of surgical treatment is to realign the joints. Read More
