Femoral Tunnel Positioning in Anterior Cruciate Ligament Reconstruction: Anteromedial Portal versus Transtibial Technique-A Randomized Clinical Trial.

 The purpose of this study was to investigate, through three-dimensional computed tomography (3D-CT), the accuracy of femoral tunnel positioning in patients undergoing anterior cruciate ligament (ACL) reconstruction, comparing transtibial (TT) and anteromedial (AM) techniques.  We evaluated postoperative 3D-CT scans of 26 patients treated with ACL reconstruction with hamstrings autograft using a low accessory AM portal technique and 26 treated with the TT technique. The position of the femoral tunnel center was measured with the quadrant method.

Use of innovative biomimetic scaffold in the treatment for large osteochondral lesions of the knee.

Purpose: Large osteochondral defects involve two different tissues characterized by different intrinsic healing capacity. Different techniques have been proposed to treat these lesions with results still under discussion. The aim of the study is to evaluate the clinical outcome of 19 patients treated with a type I collagen-hydroxyapatite nanostructural biomimetic osteochondral scaffold at minimum follow-up of 2 years.

Articular cartilage engineering with Hyalograft C: 3-year clinical results.

Unlabelled: The use of tissue engineering for cartilage repair has emerged as a potential therapeutic option and has led to the development of Hyalograft C, a tissue-engineered graft composed of autologous chondrocytes grown on a scaffold entirely made of HYAFF 11, an esterified derivative of hyaluronic acid. Here we present the results of an ongoing multicenter clinical study conducted with the primary objective to investigate the subjective symptomatic, functional and health-related quality of life outcomes of patients treated with Hyalograft C. Clinical results on the cohort of 141 patients with followup assessments ranging from 2 to 5 years (average followup time: 38 months), are reported.

Deep venous thrombosis and pulmonary embolism after knee arthroscopy in athletes carrying the thrombophilic factor lupus anticoagulant.

In patients undergoing arthroscopic knee surgery, deep venous thrombosis and pulmonary embolism are rare and there is not clear indication as to the necessity of thromboprophylactic treatment in these patients. However, the role of coagulation disorders in thrombotic events following arthroscopy is unknown. We report 2 cases of massive deep venous thrombosis and pulmonary embolism after knee arthroscopy in athletes carrying the thrombophilic factor lupus anticoagulant, but with no personal or familial history of thrombotic diseases.

Onset of Berger disease after Staphylococcus aureus infection: septic arthritis after anterior cruciate ligament reconstruction.

Septic arthritis is rare in patients undergoing knee arthroscopic surgery. If the infection is due to Staphylococcus aureus, patients might experience fever, severe clinical syndromes, and extra-articular manifestations, including vasculitis and glomerulonephritis. We describe a case of onset of immunoglobulin A nephropathy (Berger disease) after S aureus septic arthritis complicating an anterior cruciate ligament surgical reconstruction.
