Graft Reorientation and Lateral Extra-articular Tenodesis in Revision Surgery for Persistent Rotational Instability of a Verticalized Anterior Cruciate Ligament Graft.

Persistent rotational instability after anterior cruciate ligament reconstruction is a relatively common postoperative complication, typically associated with graft verticalization due to improper femoral tunnel placement, especially with classic transtibial femoral tunnel techniques. This article describes a technique designed to reorient a verticalized anterior cruciate ligament graft at its femoral insertion to a more anatomic position in the coronal and sagittal planes, aiming to restore knee stability without the need for a complete revision operation. Additionally, a lateral extra-articular tenodesis with fascia lata is added to reinforce rotational stability.

The Proportion of Meniscus Tears Considered Repairable, and Thus Repaired, Increased During a Single Surgeon's Practice of 20 Years.

Purpose: The purpose of this study was to evaluate practice patterns of a single surgeon with respect to meniscectomy and meniscal repair over a 20-year period at a single institution.

Methods: A cross-sectional descriptive study was carried out by reviewing the surgical data from the past 20 years (2002-2021) of patients who underwent arthroscopic primary meniscal surgery. Age, sex, knee and meniscus affected, morphology of the meniscal tear, meniscal radial location, location on the axial plane, tissue quality, and associated injuries were recorded.

Improved tibiofemoral contact restoration after transtibial reinsertion of the anterior root of the lateral meniscus compared to in situ repair: a biomechanical study.

Purpose: To compare biomechanical behaviour of the anterior root of the lateral meniscus (ARLM) after a transtibial repair (TTR) and after an in situ repair (ISR), discussing the reasons for the efficacy of the more advantageous technique.

Methods: Eight cadaveric human knees were tested at flexion angles from 0° to 90° in four conditions of their ARLM: intact, detached, reinserted using TTR, and reinserted using ISR. Specimens were subjected to 1000 N of compression, and the contact area (CA), mean pressure (MP), and peak pressure (PP) on the tibial cartilage were computed.

Anterior Cruciate Ligament Revision Surgery Associated to Lateral Collateral and Anterolateral Ligaments Reconstruction With Single Achilles Tendon Allograft and Single Femoral Tunnel.

Lateral collateral ligament (LC) injuries that go unnoticed when associated with an anterior cruciate ligament (ACL) tear can increase stress forces on the ACL graft causing its failure. Furthermore, it is a main stabilizer to varus stress and external rotation. On the other hand, the reinforcement of anterolateral structures during ACL reconstruction has regained popularity in recent years, because evidence has shown that it increases the control of rotational laxity and decreases ACL graft failures, especially in revision surgery.

Biomechanical consequences of anterior root detachment of the lateral meniscus and its reinsertion.

Treatment of posterior meniscal roots tears evolved after biomechanical evidence of increased pressures on the tibiofemoral cartilage produced by this lesion and the subsequent accelerated development of arthritis or osteonecrosis observed clinically. However, little is known about the consequences of the detachment of the anterior roots. This in-vitro study analyzes the biomechanical changes in the tibiofemoral joint caused by avulsion of the anterior root of the lateral meniscus.
