Combined Medial Patellofemoral Ligament, Medial Quadriceps Tendon-Femoral Ligament, and Medial Patellotibial Ligament Reconstruction for Patellar Instability: A Technical Note.

Lateral patellar dislocations often occur in a young, athletic population of recurrent dislocators with generalized laxity and an interest in returning to an active lifestyle. A recent appreciation for the distal patellotibial complex has directed surgeons toward attempting to re-create the native anatomy and knee biomechanics during medial patellar reconstructive procedures. By reconstructing the medial patellotibial ligament (MPTL) in addition to the medial patella-femoral ligament (MPFL) and medial quadriceps tendon-femoral ligament (MQTFL), the current article describes a potentially more stable construct that can be utilized in patients with subluxation with the knee in full extension, patellar instability with the knee in deep flexion, genu recurvatum, and generalized hyperlaxity.

Bilateral Exudative Retinal Detachments, Chemosis, and Impaired Ocular Motility in the Setting of Preeclampsia and HELLP Syndrome.

Purpose: We present a complication of preeclampsia and hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome including bilateral exudative retinal detachments, bullous chemosis, and impaired ocular motility.

Methods: The patient was followed in the inpatient and outpatient setting with clinical examinations, optical coherence tomography, widefield fundus photography, neuroimaging including magnetic resonance imaging of the brain/orbits, as well as carotid artery ultrasonography.

Results: Our patient was admitted with bilateral vision changes in the setting of preeclampsia and HELLP syndrome and was found to have bilateral exudative detachments, retinal exudation, severe bullous chemosis, and impaired motility.

Vertebral Augmentation in Spine Surgery.

Vertebral augmentation has been a well-studied adjunct percutaneous procedure in spine surgery. Cement augmentation has been used in the treatment of compression fractures through kyphoplasties or vertebroplasties. Historically, data have shown no difference between treating compression fractures conservatively versus with percutaneous cement augmentation procedures.

Medial patellofemoral ligament reconstruction in skeletally immature patients without correction of bony risk factors leads to acceptable outcomes but higher failure rates.

Objectives: To report outcomes and re-dislocation rates of medial patellar stabilizers reconstruction without bone procedures for correction of anatomical risk factors for patellar instability in skeletally immature patients; to compare isolated medial patellofemoral ligament (MPFL) reconstruction to combined MPFL and medial patellotibial ligament (MPTL) reconstruction in this population.

Methods: Patients with open physis and bone abnormalities including patella alta and/or increased tibial tubercle-trochlear groove (TT-TG) distance and/or trochlear dysplasia underwent MPFL reconstruction, either isolated or associated with MPTL reconstruction. Preoperative, 1-year follow-up and the latest follow-up (5 years minimum) data were collected.

The Rationale for Radiation Therapy in Alzheimer's Disease.

Alzheimer's Disease (AD) represents a major health problem without effective treatments. As the incidence of the disease will continue to rise, it is imperative to find new treatment options to halt or slow disease progression. In recent years, several groups have begun to study the utility of low total dose radiation therapy (LTDRT) to inhibit some of the pathological features of AD and improve cognition in a variety of animal models.

Preservation of Motion in Spine Surgery.

The number of spinal procedures and spinal fusions continues to grow. Although fusion procedures have a high success rate, they have inherent risks such as pseudarthrosis and adjacent segment disease. New innovations in spine techniques have sought to eliminate these complications by preserving motion in the spinal column.

Medial Patellofemoral Ligament Reconstruction in Obese Patients Results in Low Complication Rates and Improved Subjective Outcomes.

Purpose: To compare outcomes, activity scores, and complication rates of obese and non-obese patients undergoing medial patellofemoral ligament (MPFL) reconstruction.

Methods: A retrospective review identified patients undergoing MPFL reconstruction for recurrent patellofemoral instability. Patients were included if they had undergone MPFL reconstruction and had follow-up for a minimum of 6 months.

Barriers to the Initiation of Telecommunicator-CPR during 9-1-1 Out-of-Hospital Cardiac Arrest Calls: A Qualitative Study.

Introduction: Fewer than 10% of individuals who suffer out-of-hospital cardiac arrest (OHCA) survive with good neurologic function. Bystander CPR more than doubles the chance of survival, and telecommunicator-CPR (T-CPR) during a 9-1-1 call substantially improves the frequency of bystander CPR.

Objective: We examined the barriers to initiation of T-CPR.

Clinical Significance of Lateral Pedicle Screw Malposition in Lumbar Spine Fusion.

Study Design: Retrospective cohort study.

Objective: Our objective was to determine whether lateral pedicle screw breach affects fusion rates and patient-reported outcomes in lumbar fusion surgery.

Summary Of Background Data: Although lateral pedicle screw malposition is considered relatively benign, few studies have focused specifically on clinical outcomes or fusion rates associated with lateral screw malposition.

Safety and Effectiveness of Mechanical Thrombectomy From the Fully Enrolled Multicenter, Prospective CLOUT Registry.

Background: We report in-hospital outcomes from the multicenter, prospective, single-arm ClotTriever Outcomes (CLOUT) registry, which enrolled up to 500 patients with proximal lower extremity deep vein thrombosis (DVT) treated with percutaneous mechanical thrombectomy using the ClotTriever System (Inari Medical).

Methods: The CLOUT registry enrolled all-comer patients with DVT, irrespective of symptom duration, thrombus age, prior treatment of the current DVT, or bilateral thrombus. The primary effectiveness end point was defined as complete or near complete (≥75%) reduction in Marder score.

Graft-Versus-Host Disease: an Update on Functional Implications and Rehabilitation Interventions.

Purpose Of Review: Despite advances in treatment, chronic graft-versus-host disease (cGVHD) remains a highly morbid complication of allogeneic hematopoietic stem cell transplantation. Due to direct effects of the disease on specific body sites, and its treatment, patients lose function. This review summarizes the latest evidence surrounding how cGVHD affects function, and restorative interventions.

A New Era in Cardiac Rehabilitation Delivery: Research Gaps, Questions, Strategies, and Priorities.

Cardiac rehabilitation (CR) is a guideline-recommended, multidisciplinary program of exercise training, risk factor management, and psychosocial counseling for people with cardiovascular disease (CVD) that is beneficial but underused and with substantial disparities in referral, access, and participation. The emergence of new virtual and remote delivery models has the potential to improve access to and participation in CR and ultimately improve outcomes for people with CVD. Although data suggest that new delivery models for CR have safety and efficacy similar to traditional in-person CR, questions remain regarding which participants are most likely to benefit from these models, how and where such programs should be delivered, and their effect on outcomes in diverse populations.
