A reduced scapulo-humeral angle contributes to the development of scapular notching in reverse total shoulder arthroplasty.

Purpose: Scapular Notching (SN) is one of the most common postoperative complications for a patient after Reverse Total Shoulder Arthroplasty (RTSA). Despite employing various strategies to mitigate SN risk, the overall incidence remains far from zero. This article introduces a new risk factor, the scapulo-humeral angle (SHA), as a key element influencing the risk for SN.

Optimised fast-track protocols in total knee arthroplasty determine shorter hospitalisation time and lower perioperative/postoperative complications.

Purpose: This literature review aims to present evidence-based clinical recommendations for the eight most debated topics related to perioperative management in total knee arthroplasty: counselling, prehabilitation, transfusion risk, tranexamic acid, drainage, analgesia, urinary catheter and compression stockings.

Methods: A multidisciplinary team conducted a systematic review on these topics. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for the literature review and result presentation.

The meniscal extrusion index is a reliable indirect sign of different meniscal lesion patterns: a classification based on percentage of meniscal extrusion.

Purpose: This study's goal is to propose a straightforward classification system based on the MEI (Meniscal Extrusion Index), a measure of meniscal extrusion, that relates to various meniscal lesion patterns and has clinical and biomechanical significance. The study's secondary goal is to determine whether the standard 3 mm meniscal extrusion parameter still has value by correlating the MEI with it.

Methods: 1350 knee MRIs that were performed over the course of 2 years made up the study cohort.

Bone marrow lesions in the knee are associated with meniscal lesions and cartilage pathologies according to the six-letter system.

Purpose: This study aims to find a correlation between bone marrow lesions (BMLs) in knee MRI and pathologies of joint structures. In addition, according to the six-letter system classification, the authors analyzed a potential association between the area affected by BMLs and the specific type of joint lesion.

Methods: The authors screened all the knee MRIs performed in the investigation center between 2017 and 2018 to identify the presence of BMLs.

Validation of a new topographic classification of bone marrow lesions in the knee: the six-letter system.

Purpose: The aim of this study was to propose and validate a new six-item topographical classification of knee bone marrow lesions in coronal MRI images, to provide an easy-to-use aid to describe their location in a more reproducible and accurate way.

Methods: This study was conducted in four phases. The first was to do a literature search for methods of describing bone marrow lesions in MRI of the knee.

Early clinical and radiological evaluation in patients with total ankle replacement performed by lateral approach and peroneal osteotomy.

Background: The Zimmer Trabecular Metal Total Ankle Replacement (Zimmer TM TAR) is a recent ankle arthroplasty approved for use in the United States and Europe. Many of the studies reporting the results of this implant are provided by surgeons involved at least in the initial design of the implant under study. The aim of this study is to describe the early clinical and radiological outcomes in patients who underwent this procedure performed by non-designer surgeons.
