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.

The clinical diagnosis of meniscal tear is not easy. Reliability of two clinical meniscal tests and magnetic resonance imaging.

Aim: to clarify the reliability of two clinical meniscal tests, McMurray's and Apley's and the MRI imaging, in order to establish how to reduce unjustified arthroscopies.

Methods: 102 patients were selected out of 160. All patients were submitted to a triple clinical examination (by a young surgeon and two skilled surgeons), MRI and an arthroscopic procedure.

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.

Surgical management of chronic, unreduced posterior dislocation of the shoulder.

Four patients with chronic posterior dislocation of the shoulder underwent surgical treatment after an average delay of 10 months from injury. They were examined clinically and radiographically at an average follow-up of 32 months. Treatment consisted of subscapularis tendon transfer (McLaughlin procedure) into the humeral defect in one case, transfer of the lesser tuberosity (McLaughlin modified procedure) in two cases, and in the fourth case-a patient with a 19-month missed dislocation and 50% humeral head lesion-a transposition of the coracoid process and conjoined tendon was performed.
