Posterolateral Corner Reconstruction: Modification of the LaPrade Technique Using Autologous Hamstring Tendon Grafts: "The Popliteofibular Loop".

Posterolateral corner (PLC) injury is a significant cause of knee instability. In recent years, a better understanding of the anatomy and biomechanics of the PLC structures has led to significant advancements in the surgical treatment of this injury. Anatomical reconstruction techniques, particularly the LaPrade technique, have shown promising results.

POSTERIOR CRUCIATE LIGAMENT RECONSTRUCTION: ARE THE RESULTS SIMILAR TO ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION?

Objective: To report and compare the results of posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) reconstructions.

Methods: In total, 42 patients were retrospectively evaluated, 20 with isolated PCL injuries (group 1) and 22 with isolated ACL ones (group 2) who were subjected to arthroscopic ligament reconstruction with autologous grafts and followed up for at least two years. To evaluate the results in group 1, objective IKDC and Lysholm scores, posterior drawer tests, and evaluations by a KT-1000 arthrometer were used, whereas for group 2, subjective IKDC and Lysholm score and the Lachman test were employed.

Efficacy and safety of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers for IgA nephropathy in children.

Background: IgA nephropathy (IgAN) is one of the most prevalent primary glomerulopathies in children. There are various studies investigating the efficacy of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) in adults with IgAN. However, only few studies evaluated the efficacy of these medications in pediatric patients.

Skeletal posterior crossbite in patient with mandibular asymmetry: an alternative solution.

Introduction: Skeletal posterior crossbite (SPCB) has a multifactorial etiology, as it may be caused by parafunctional habits, atypical position of the tongue, tooth losses and maxillary or mandibular transverse skeletal asymmetries. Skeletal involvement may lead to facial changes and an unfavorable aesthetic appearance. The treatment of SPCB diagnosed in an adult patient should be correctly approached after the identification of its etiologic factor.

Double-bundle posterior cruciate ligament reconstruction: No differences between two types of autografts in isolated or combined lesions.

Background: To demonstrate and compare results obtained with the transtibial double-bundle posterior cruciate ligament (PCL) reconstruction technique using two types of autografts in isolated and combined PCL lesions.

Methods: Fifty-two patients with isolated or combined PCL injuries underwent double-bundle PCL reconstruction and were retrospectively evaluated. Among them, 34 were reconstructed using ipsilateral quadriceps and semitendinosus tendon grafts, and 18 were reconstructed using bilateral hamstring tendon grafts.
