Background: Graft failure and low rates of return to sport are major concerns after anterior cruciate ligament (ACL) reconstruction, particularly in a population at risk. Purpose: To evaluate the association between reconstruction techniques subsequent graft rupture return-to-sport patients aged 16 30 years participating pivoting sports. Study Design: Cohort study; Level evidence, 2. Methods: A prospective study undergoing primary ACL with bone–patellar tendon–bone (B-PT-B) graft, quadrupled...

Background: Reconstruction of the anterior cruciate ligament (ACL) is one most common procedures in orthopaedic surgery. However, even with advances surgical techniques and implants, some patients still have residual anterolateral rotatory laxity after reconstruction. A thorough study anatomy region knee needed. Purpose: To determine measurements points attachments (ALL). Study Design: Descriptive laboratory study. Methods: Dissections structures were performed 20 human cadavers. After...

Despite technologic advances in the surgical technique for anterior cruciate ligament (ACL) reconstruction, some patients continue to have rotational instability postoperatively. Recently, authors reported anatomic and functional characteristics of anterolateral (ALL), a structure that originates near lateral epicondyle on femur inserts tibia between Gerdy tubercle fibular head. Recent biomechanical studies shown ALL is an important stabilizer against tibial rotation, its reconstruction has...

We present a new technique for the combined intra- and extra-articular reconstruction of anterior cruciate ligament. Intra-articular is performed in an outside-in manner according to precepts anatomic femoral tunnel technique. Extra-articular with gracilis tendon while respecting parameters origin insertion points path described knee anterolateral

Recent anatomic studies have confirmed the presence of a true ligament structure, anterolateral (ALL), in region knee. This structure is involved rotatory instability knee and might explain why some isolated reconstructions anterior cruciate result residual pivot shift. Therefore, when considering least invasive method for reconstruction this it important to identify corresponding bony landmarks on radiographic images.To establish femoral tibial ALL frontal lateral views.Descriptive...

To evaluate the presence of anterolateral ligament (ALL) knee in magnetic resonance imaging (MRI) examinations. Thirty-three MRI examinations on patients' knees that were done because indications unrelated to instability or trauma evaluated. T1-weighted images sagittal plane and T2-weighted with fat saturation axial, coronal planes obtained. The evaluated by two radiologists experience musculoskeletal pathological conditions. In assessing visibility, we divided analysis into three portions...

Recent studies clearly characterize the anatomical parameters of knee anterolateral ligament (ALL). The potential clinical importance this is exemplified by some patients with possible combined Anterior Cruciate Ligament (ACL) and ALL rupture who do not progress satisfactorily following isolated ACL reconstruction. Previous biomechanical have assessed resistance in order to address reconstruction strategies; however, these reported conflicting results. Thus, study aimed evaluate linear means...

Broad variation in the reported rate of magnetic resonance imaging (MRI)-detected abnormalities anterolateral structures anterior cruciate ligament (ACL)-injured knee suggests a lack reliability that has limited use MRI clinical decision making.The aim this study was to determine prevalence and spectrum acute ACL-injured knees, using contralateral uninjured as reference. We hypothesized evaluation acutely injured (using reference) would allow reliable identification structures.Cohort...

Background: The anterolateral ligament (ALL) has been shown to have an important role in rotatory stability of the knee. While there is abundant research on sex-based differences related anterior cruciate (ACL) rupture, a paucity literature such ALL. Purpose: To define any ALL with regard length, width, and thickness. Study Design: Descriptive laboratory study. Methods: was initially evaluated 165 unpaired knees (92 males 65 females after exclusion criteria applied). thickness were measured...

Background: Recent anatomical studies have identified the anterolateral ligament (ALL). Injury to this structure may lead presence of residual pivot shift in some reconstructions anterior cruciate ligament. The behavior length and its tension during range motion has not been established is essential when planning reconstruction. Purpose: To establish differences ALL knee motion. Study Design: Descriptive laboratory study. Methods: Ten unpaired cadavers were dissected. attachments isolated....

No consensus exists regarding the anatomic characteristics of knee anterolateral ligament (ALL). A critical analysis dissections described in previous studies allows division ALL into 2 groups with similar characteristics. The presence considerable variability suggests that authors may not be referring to same structure.To perform a lateral dissection, by layers, seeking characterize variants for on knee. We hypothesized we would identify and these have distinct characteristics.Descriptive...

Combined anterior cruciate ligament (ACL) and anterolateral (ALL) reconstruction is associated with improved clinical outcomes as compared isolated intra-articular reconstruction, but the indications are not precisely defined. It may be case that patients proven injury on preoperative imaging most likely to benefit, accuracy of magnetic resonance (MRI) known.To evaluate correlation between MRI surgical exploration in acute ACL-injured knees. The hypothesis was a positive would identified...

Background: Isolated reconstruction of the anterior cruciate ligament (ACL) does not reestablish normal knee biomechanics in cases associated injuries to anterolateral structures. Studies evaluating potential clinical effect (ALL) injury on treatment ACL are necessary validate findings biomechanical studies. Purpose: To evaluate outcomes and failure rate patients with without ALL diagnosed using magnetic resonance imaging. Study Design: Cohort study; Level evidence, 2. Methods: A prospective...
