Posterolateral Knee Ligament Reconstruction Using the Arciero Technique Provides Greater Rotational Stability Than the Modified Larson Technique: A Biomechanical Study.

Background: It is still unknown if the double-femoral tunnel technique (Arciero [ARC]) provides better stability as compared with the single-femoral tunnel technique (modified Larson [LAR]) in posterolateral corner reconstruction. The ideal angle of fixation of the popliteofibular strand in ARC is also unknown.

Hypotheses: The ARC provides greater external rotation (ER) stability than the LAR (hypothesis 1); there is no difference in varus rotation (VR) stability between LAR and ARC (hypothesis 2); and femoral fixation of the popliteofibular strand at 60° during the ARC leads to greater ER stability than fixation at 30° or 90° of knee flexion (hypothesis 3).

Effects of Electroconvulsive Therapy on Brain Structure - a Neuroradiological Investigation into White Matter Hyperintensities, Atrophy, and Microbleeds.

Background: Electroconvulsive therapy (ECT) is a well-established treatment for severe depression, yet it remains stigmatized due to public perceptions linking it with brain injury. Despite extensive research, the neurobiological mechanisms underlying ECT are not fully elucidated. Recent findings suggest that ECT may work through disrupting depression circuitry.

Infratuberositary slope-decreasing anterior closed wedge proximal tibial osteotomy is safe and shows rapid bone healing.

Purpose: Different techniques of slope-decreasing anterior closed-wedge proximal tibial osteotomy (ACW-PTO) have been described. To determine the peri- and post-operative complication rate and obtain data on bone healing in ACW-PTO with an infratuberositary approach.

Methods: A total of 170 consecutive ACW-PTO of two sports-orthopaedic centres were retrospectively evaluated (97 and 73, respectively).

Stent-in-Stent Intervention for Pulmonary Vein in Stent Restenosis: A Long-Term Follow-Up Case Report.

Introduction: Pulmonary vein (PV) restenosis develops with reported incidence rates of up to 50%. Balloon angioplasty seems to be the widely preferred treatment of choice.

Method And Results: A 54-year-old man with long history of atrial fibrillations developed PVS secondary to multiple radiofrequency ablation procedures.
