Bernholt, MD, [...]
Technique for Treatment of Subchondral Compression Fracture of the Lateral Femoral Condyle Associated With ACL Tear
Abstract: Excessive knee pivoting that causes a complete anterior cruciate ligament (ACL) tear may result in a subchondral compression fracture on the lateral femoral condyle after impacting the lateral tibial condyle. Because this mechanism is similar to the [...]
Bone graft substitute for tunnel filling improved ACL reconstruction outcomes
Overview Researchers randomly assigned 40 patients undergoing two-stage revision ACL reconstruction to receive either autologous iliac crest cancellous bone graft for tunnel grafting (control group; n=20) or silicate-substituted calcium phosphate in the form of sculptable microgranules (Actifuse MIS [...]
Incidence of Displaced Posterolateral Tibial Plateau and Lateral Femoral Condyle Impaction Fractures in the Setting of Primary Anterior Cruciate Ligament Tear
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, [...]
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 [...]
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 [...]
Clinical Characteristics and Outcomes After Primary ACL Reconstruction and Meniscus Ramp Repair
Authors: Nicholas N. DePhillipo, PhD, ATC, OPE-C; Grant J. Dornan, MSc; Travis J. Dekker, MD; Zachary S. Aman,BA; Lars Engebretsen, MD, PhD, and Robert F. LaPrade, MD, PhD Background Satisfactory outcomes have been reported after all-inside meniscus ramp [...]
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 [...]
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. [...]
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 [...]
Lateral Posterior Tibial Slope in Male and Female Athletes Sustaining Contact Versus Noncontact Anterior Cruciate Ligament Tears
Background Lateral posterior tibial slope (PTS) has been identified as a risk factor for primary anterior cruciate ligament (ACL) tears. Purpose/Hypothesis The purpose was to prospectively determine if there was a difference in lateral PTS between male and [...]
Steeper Tibial Slopes, Like Steeper Ski Slopes, Might Lead to More ACL Stress and Tears
Commentary & Perspective Steeper Tibial Slopes, Like Steeper Ski Slopes, Might Lead to More ACL Stress and Tears Commentary on an article by Dean Wang, MD, et al.: “Tibiofemoral Kinematics During Compressive Loading of the ACL-Intact and ACL-Sectioned [...]
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 [...]
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 [...]
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 [...]
Tibial Slope and Its Effect on Force in Anterior Cruciate Ligament Grafts
Background Previous work has reported that increased tibial slope is directly correlated with increased anterior tibial translation, possibly predisposing patients to higher rates of anterior cruciate ligament (ACL) tears and causing higher rates of ACL graft fail- ures [...]
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 [...]
Influence of Meniscal and Chondral Lesions on Patient-Reported Outcomes After Primary Anterior Cruciate Ligament Reconstruction at 2-Year Follow-up
