Evaluation of Thigh Muscle Strength in Adolescent Patients After Anterior Cruciate Ligament Reconstruction With Lateral Extra-articular Tenodesis or Anterolateral Ligament Reconstruction.

Background: There has been increased interest in lateral extra-articular procedures, such as anterolateral ligament reconstruction (ALLR) or lateral extra-articular tenodesis (LET), to reduce anterolateral rotation instability of the knee after anterior cruciate ligament reconstruction (ACLR). Despite promising surgical outcomes with these techniques, their impact on knee strength recovery is unknown.

Hypothesis: Patients undergoing lateral extra-articular procedures at the time of ACLR would have impaired thigh muscle strength at 6 to 9 months after surgery.

Thoracolumbar spine muscle size and composition changes in long-duration space missions.

Muscle atrophy occurs with extended exposure to microgravity. This study quantified the overall muscle size, lean muscle area and fat infiltration changes pre- to post-flight that occur in the thoracic and lumbar spine with long-duration spaceflight. Pre- and post-flight magnetic resonance imaging (MRI) scans were obtained from 9 crewmembers on long-duration (≥6 months) International Space Station (ISS) missions.

Onchocerciasis is not a major cause of blindness in two endemic villages in Sierra Leone.

Objective: Sierra Leone, a country where onchocerciasis is endemic in 14 of the 16 districts, was the focus of our investigation. Despite 17 rounds of annual ivermectin treatment since 2005, a report circulated by a local politician indicated an increase in cases of suspected onchocerciasis-related vision impairment in two villages (Mangobo and Petifu) in Tonkolili district. In response, the National Neglected Tropical Disease Program conducted a comprehensive investigation.

Self-directed violence and unclear intent presentation within a major trauma system. A multisite analysis.

Background: Determining trauma as an act of Self-directed violence (SDV) or from high risk or unclear behaviours is challenging for trauma clinicians and may be affected by patient sex and mechanism of injury. The aim of this study was to examine the differences in characteristics and outcomes between those who have intentionally directed violence towards themselves with those of unclear intent, within a regional trauma system.

Methods: Data was collected between January 2018 and December 2021 in patients who had been identified as a result of either self-directed violence (SDV) defined as any intentional act that can cause injury to one's self, including death or participated in high-risk behaviours, where the intent was unclear (UI).

Comparison of Postoperative Strength Progression and Outcomes Following Primary Versus Secondary ACL Reconstruction in the Young Athlete.

Background: Return to sport testing after ACL reconstruction (ACLR) is becoming increasingly popular. Anecdotally, some believe that patients who undergo a second ACL surgery on either the ipsilateral or contralateral leg progress through their rehabilitation goals faster the second time through. The purpose of this study was to evaluate the rate of strength progression in return to sport testing after primary and secondary ACLR surgeries in a young, active population.
