Anterior cruciate ligament (ACL) injury is a significant cause of injury among pediatric patients with an increasing incidence. ACL insufficiency can lead to lifelong disability as further joint deterioration occurs in the form of meniscal and subsequently chondral pathology. Techniques for pediatric ACL reconstruction can broadly be classified as physeal-sparing and non-physeal-sparing. Bone age is frequently used when deciding which technique to employ. Patients are candidates for physeal-sparing, over-the-top iliotibial band reconstruction (i.e., modified MacIntosh II) when they have >4 years remaining before skeletal maturity. The modified Macintosh procedure provides both intra- and extra-articular rotational and translational constraint. This Technical Note describes the senior author's modified MacIntosh technique using knotless all-suture anchor fixation in a suture staple technique to mitigate risk of physeal damage.

Background And Aims: El-Ganzouri risk index (EGRI) scoring is a predictive tool for difficult video laryngoscope (VL) guided tracheal intubation, and its use has been studied for various VLs. This study evaluates the predictive value of EGRI scoring for difficult laryngoscopy and tracheal intubation with King Vision VL.
Methods: Airway assessment was performed preinduction using the EGRI score.

The force-length relationship is usually obtained for isometric contractions with maximal activation, but less is known about how sarcomere length affects force during submaximal activation. During submaximal activation, length-dependent alterations in calcium sensitivity, owing to changes in cross-bridge kinetics (rate of attachment and/or detachment), result in an activation-dependent shift in optimal length to longer sarcomere lengths. It is known that sarcomere length, as well as temperature and phosphorylation of the regulatory light chains of myosin, can modify Ca⁺ sensitivity by altering the probability of cross-bridge interaction.

Background: Nasotracheal intubation is challenging for anaesthesiologists in faciomaxillary injuries due to the anticipated difficult airways. The effectiveness of a non-channelled McGrath video laryngoscope was compared with a conventional Macintosh laryngoscope during nasotracheal intubation.
Methods: Sixty American Society of Anaesthesiologists I-II patients aged between 18 and 60 years of both sexes undergoing elective faciomaxillary surgeries from September 2019 to February 2020 were prospectively randomised into two groups (Macintosh laryngoscope Group, McGrath video laryngoscope Group) of 30.
