Semimembranosus Tendon Findings in Acute Anterior Cruciate Ligament Tears: MRI Evaluation and Associated Lesions.

Background: The semimembranosus (SM) tendon acts as a secondary dynamic stabilizer of the knee. It restrains external rotation and anterior translation of the medial compartment. Its role in the mechanism of injury during anterior cruciate ligament (ACL) rupture is unknown.

Failure rate analysis and clinical outcomes of two different femoral tunnel positions using anteromedial portal technique in anterior cruciate ligament reconstruction.

Aim: To analyze two different femoral tunnel positions and to evaluate their correlation with clinical, functional outcomes and surgical revision rate in patients who underwent primary arthroscopic anterior cruciate ligament (ACL) reconstruction with anteromedial (AM) portal technique.

Methods: From January 2015 to October 2018, we recruited 244 patients that underwent primary single-bundle ACL reconstruction, using four strand-semitendinosus graft and AM portal technique for femoral tunnel placement. Patients were divided into two groups based on the different femoral tunnel positions: 117 patients of group A had ACL footprint center femoral tunnel position compared with 127 patients of group B, with femoral tunnel placement close to the AM bundle footprint.

Oyster eaters: From consumer practices to the representation of risks.

This article focuses on a study of the representation of the health risks associated with oyster consumption. The research was initially part of an interdisciplinary project looking at the differences between diploid and triploid oysters. The triploid oyster has been genetically modified to stem reproduction, the process responsible for milt, in order that it can be consumed all year round.

Posterolateral bundle reconstruction of the anterior cruciate ligament to restore rotational stability of the knee.

Only 5-10% of partial tears of the anterior cruciate ligament (ACL) are symptomatic, especially in high demand individuals or in patients practicing sports requiring rotational motions.. A certain preoperative diagnosis of this condition is challenging and often needs the combination of clinical examination, magnetic resonance imaging (MRI) and knee-laxity tool measurements.
