Abstract Bone bruising of the posterolateral tibial plateau and the lateral femoral condyle sulcus terminalis has a well-established association with anterior cruciate ligament (ACL) tears. Impaction fractures of the femur and tibia may occur in these locations; however, there [...]
Morphologic Variants of Posterolateral Tibial Plateau Impaction Fractures in the Setting of Primary Anterior Cruciate Ligament Tear
Abstract Impaction fractures of the posterolateral tibial plateau commonly occur in the setting of anterior cruciate ligament (ACL) tears, with considerable variability found in fracture size and morphologic features. The primary objective was to characterize different morphologic variants of [...]
ACL and Posterolateral Corner Injuries
Abstract The importance of the posterolateral corner (PLC) with respect to knee stability, particularly in the setting of anterior cruciate ligament (ACL) deficiency, has become more apparent in recent years. The purposes of this article are to review the [...]
Posterior Medial Meniscus Root Tears Potentiate the Effect of Increased Tibial Slope on Anterior Cruciate Ligament Graft Forces
Abstract Increased posterior tibial slope and posterior medial meniscus root tears increase the force experienced by the anterior cruciate ligament (ACL) and predispose patients to higher rates of primary ACL injury or ACL graft failure after an ACL reconstruction [...]
Combined Anterior Cruciate Ligament Reconstruction and Lateral Extra-Articular Tenodesis
Abstract Anterolateral rotational instability may persist after anterior cruciate ligament (ACL) reconstruction for a variety of reasons including damage to lateral or posterolateral structures, injury to the meniscus, disruption of anterolateral soft tissue structures, or increased tibial slope. In [...]
Influence of Medial Meniscus Bucket-Handle Repair in Setting of Anterior Cruciate Ligament Reconstruction on Tibiofemoral Contact Mechanics: A Biomechanical Study
Purpose: To compare the impact of an inside-out repair versus meniscectomy of a medial meniscus bucket-handle tear in restoring native contact areas and pressures across the tibial plateaus in the setting of an anterior cruciate ligament (ACL) reconstruction (ACLR). [...]
Steeper Tibial Slopes, Like Steeper Ski Slopes, Might Lead to More ACL Stress and Tears
Commentary & PerspectiveSteeper Tibial Slopes, Like Steeper Ski Slopes, Might Lead to More ACL Stress and TearsCommentary on an article by Dean Wang, MD, et al.: “Tibiofemoral Kinematics During Compressive Loading of the ACL-Intact and ACL-Sectioned Knee. Roles of Tibial [...]
Anterior Closing Wedge Proximal Tibial Osteotomy for Slope Correction in Failed ACL Reconstructions
Abstract Increased sagittal plane posterior tibial slope has been identified as a risk factor for primary anterior cruciate ligament reconstruction (ACLR) failure. Although ACLR failure is multifactorial, correction of sagittal plane posterior tibial slope should be evaluated in patients [...]
Re-revision Anterior Cruciate Ligament Reconstruction: An Evaluation From the Norwegian Knee Ligament Registry
Purpose To identify the rate of re-revision anterior cruciate ligament reconstruction(ACLR) to estimate the influence of patient-related factors on the risk of re-revision ACLR. The secondary aim of the study was to report the intra-articular findings and patient-related factors at [...]
Current Trends Among US Surgeons in the Identification, Treatment, and Time of Repair for Medial Meniscal Ramp Lesions at the Time of ACL Surgery
2019 The Orthopaedic Journal of Sports Medicine Meniscal ramp lesions are becoming increasingly recognized. Ramp lesions have been described as tears at the posterior meniscocapsular junction and/or tears of the posterior meniscotibial ligament, and they have a reported incidence [...]
A History of Anterior Cruciate Ligament Reconstruction at the National Football League Combine Results in Inferior Early National Football League Career Participation
2018 Arthroscopy Journal Anterior cruciate ligament (ACL) tears have been reported to have an annual incidence of 0.17 per 1,000 players in college football and 0.7 per 1,000 players in the National Football League (NFL). Previous data have shown that [...]
Influence of Meniscal and Chondral Lesions on Patient-Reported Outcomes After Primary Anterior Cruciate Ligament Reconstruction at 2-Year Follow-up
Background: Meniscal and chondral lesions are commonly associated with anterior cruciate ligament (ACL) tears, and these lesions may play a role in patient outcomes after ACL reconstruction. Purpose: To determine the effects of the presence and location of meniscal and [...]
Primary Versus Revision Anterior Cruciate Ligament Reconstruction: Patient Demographics, Radiographic Findings, and Associated Lesions
Purpose: The purpose of this study was to evaluate the differences in intra-articular pathology, demographic characteristics, and radiographic characteristics of the knee associated with primary anterior cruciate ligament reconstruction (ACLR) versus revision ACLR at the time of initial presentation with [...]
Biologic Approaches for the Treatment of Partial Tears of the Anterior Cruciate Ligament
The anterior cruciate ligament (ACL) is one of the most studied structures of the human musculoskeletal system, being the subject of many anatomic and biomechanical studies. While treatment options for complete ruptures of the ACL are well studied, partial ACL tears [...]
Overlap Between Anterior Cruciate Ligament and Anterolateral Meniscal Root Insertions
AJSM 2016 Over the past decade, there has been an increasing emphasis on anatomic anterior cruciate ligament (ACL) reconstruction to best restore knee kinematics after an ACL tear. Although studies have shown that the position, size and shape of the [...]
Posterior Wall Blowout During Anterior Cruciate Ligament Reconstruction: Suspensory Cortical Fixation With a Screw and Washer Post
2016 Arthroscopy Posterior wall blowout can be a devastating intraoperative complication in anterior cruciate ligament reconstruction. This loss of osseous containment can cause difficulty with graft fixation and can potentially lead to early graft failure if unrecognized and left untreated. [...]
Posterior Wall Blowout in Anterior Cruciate Ligament Reconstruction
OJSM 2016 Violation of the posterior femoral cortex, commonly referred to as posterior wall blowout, can be a devastating intraoperative complication in anterior cruciate ligament (ACL) reconstruction and lead to loss of graft fixation or early graft failure. If cortical [...]
