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...

Over the long term, acute patellar dislocations can result in instability, with high recurrence rates after nonoperative treatment.To compare results of operative (reconstruction medial patellofemoral ligament [MPFL]) versus treatment primary dislocation.Randomized controlled trial; Level evidence, 1.Thirty-nine patients (41 knees) (mean age, 24.2 years; range, 12-38 years) dislocation were randomized into 2 groups. One group was treated nonoperatively immobilization and physiotherapy, other...

Background: The patellar tendon has limited ability to heal after harvesting its central third. Platelet-rich plasma (PRP) could improve healing. Hypothesis: Adding PRP the harvest site would donor healing and clinical outcome at 6 months anterior cruciate ligament (ACL) reconstruction with a graft. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Twenty-seven patients were randomly divided receive (n = 12) or not 15) in during ACL reconstruction. primary was...

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...

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...

Nonanatomic anterior cruciate ligament (ACL) reconstruction (ACLR) with double-stranded semitendinosus grafts in children open physes has been described as a successful surgical technique short-term follow-up clinical reports.To evaluate the outcomes of nonanatomic ACLR and minimum 15 years' follow-up.Case series; Level evidence, 4.Twelve patients an average age 10.7 years (range, 8.3-12.4 years) underwent between 1991 1998. All were classified Tanner development stage 2 or lower. The...

Background: Anatomic and magnetic resonance imaging (MRI) studies have recently characterized the knee anterolateral ligament (ALL). So far, no study has focused on confirming whether evaluated MRI parameters truly correspond with ALL anatomy. Purpose: To assess validity of in detecting using an anatomic evaluation as reference. Study Design: Descriptive laboratory study. Methods: A total 13 cadaveric knees were subjected to then dissection. Dissection was performed according previous...

The anterolateral ligament (ALL) of the knee has recently been described in detail. Most studies ALL have conducted adults; therefore, little is known about anatomy and histology younger patients, nothing fetal presence ALL.To evaluate human fetuses to determine its or absence describe microscopic histological features compared with findings adults.Descriptive laboratory study.Twenty cadaveric specimens were used. mean age was 28.64 ± 3.20 weeks. dissected region knee, anatomic parameters,...

To evaluate the incidence of sports injuries in college athletes from same institution 1993 to 2013.Athletes 13 modalities were interviewed about presence and type injury, treatment time withdrawal, based on questionnaire "Injury Surveillance System" (ISS). Data analyzed with graphs tables injury prevalence by gender, age, site modality. We also average withdrawal athletes, returning practice new lesions.It was observed that 49.91% showed some similar between genders; most frequent anterior...
