#1
Julien Billières, Hermès Miozzari, Anne Lübbeke, Didier Hannouche
Degenerative meniscal tears (DMT) are common, often asymptomatic, and are associated with early-stage knee osteoarthritis in patients over 35 years of age. Conservative treatment, including exercise, physiotherapy and pain medication, should be offered as a first management approach for patients with symptomatic DMT. The indication for partial arthroscopic meniscectomy should be considered carefully, and based on specific criteria. Recently, several randomized controlled studies comparing partial medial meniscectomy to conservative treatment or to a sham procedure have questioned the effectiveness of surgical treatment of these lesions...

INTRODUCTION: Double-button devices for endoscopic management of acute acromioclavicular joint dislocation (ACJD) provide satisfactory short-term functional and radiological results. However, little exists in the literature regarding the long- and medium-term results of these implants, especially regarding the evolution of the acromioclavicular joint (ACJ). HYPOTHESI: Satisfactory and steady long- and medium-term outcomes can be achieved in patients with acute ACJD undergoing endoscopically assisted ACJ repair using a single double-button device...

: Liver transplantation is one of the treatments for haemophilic patients having severe liver cirrhosis who are infected with the hepatitis C virus. Patients with haemophilia can develop arthroplasty requiring surgical intervention, and the surgical outcomes of patients undergoing such procedures after liver transplant has not been reported. Treatment for arthropathy is important for improving the quality of life for patients who survive after liver transplantation. We report the first case of ankle arthroscopic arthrodesis in a patient with haemophilia B after undergoing living donor liver transplantation...

Meniscus tissues have limited regenerative capacity once damaged. The treatment options for the meniscus tissue regeneration have been limited to arthroscopic meniscectomy or surgical interventions. The injectable hydrogels based system would provide an alternative to the conventional meniscus therapy by providing a minimally invasive treatment alternative. Here we utilized enzyme-based approaches to fabricate tissue adhesive hydrogels for meniscus repair. Tyramine (TA) conjugated hyaluronic acid (TA-HA) and gelatin are susceptible to tyrosinase (TYR)-mediated crosslinking in vitro and in vivo...

Intracellular calcium ([Ca2+]i) signaling is an essential universal secondary messenger in articular chondrocytes. However, little is known about its spatiotemporal features in the context of osteoarthritis (OA). Herein, by examining the cartilage samples collected from patients undergoing knee arthroscopic surgery, we investigated the spatiotemporal features of spontaneous [Ca2+]i signaling in in situ chondrocytes at different OA stages. Our data showed zonal dependent spontaneous [Ca2+]i signaling in healthy cartilage samples under 4 mM calcium environment...
