Enhancing cognitive processing therapy via stellate ganglion blocks: A pilot randomized trial

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Although trauma‐focused psychotherapies, such as cognitive processing therapy (CPT), are effective treatments for posttraumatic stress disorder (PTSD), a substantial portion of individuals exhibit a diminished response. Stellate ganglion block (SGB), an anesthetic procedure targeting the sympathetic nervous system, has shown promise for PTSD ...

Posterior cruciate ligament involvement leads to inferior outcomes in multiligament knee injuries involving the medial collateral ligament: A systematic review and meta‐analysis

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Multiligament knee injuries (MLKIs) involving the medial collateral ligament (MCL) present unique challenges in surgical management and postoperative rehabilitation. This systematic review and meta‐analysis aimed to evaluate postoperative patient‐reported outcomes in patients with MCL‐involved MLKIs, with a minimum follow‐up of 2 years.

MRI‐based deep learning models match or surpass physician performance for early detection and staging of avascular necrosis of the femoral head: A systematic review

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Efficient and reliable magnetic resonance imaging (MRI)‐based diagnosis of early avascular necrosis of the femoral head (AVNFH) is essential for guiding treatment but remains challenging due to variability in clinician experience. Deep learning (DL) models offer a promising solution. This review evaluates and summarizes the performance

Effects of fatigue are more pronounced on the uninjured side during single‐limb jumps 2 years after an acute Achilles tendon rupture

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Achilles tendon rupture (ATR) is a serious lower limb injury that may result in persistent deficits in strength and endurance of the calf muscles. Compensatory mechanisms at proximal joints are known, but the effects of fatigue are less studied.
