Biomechanical Analysis of an Arthroscopic Broström Ankle Ligament Repair and a Suture Anchor-Augmented Repair

2018-09-25T10:09:16-06:00

Secondary surgical repair of ankle ligaments is often indicated in cases of chronic lateral ankle instability. Recently, arthroscopic Broström techniques have been described, but biomechanical information is limited. The purpose of the present study was to analyze the biomechanical properties of an arthroscopic Broström repair and augmented repair with a proximally placed suture anchor. It [...]

Magnetic Resonance Imaging Characterization of Individual Ankle Syndesmosis Structures in Asymptomatic and Surgically Treated Cohorts

2018-09-25T10:09:16-06:00

Syndesmosis sprains can contribute to chronic pain and instability, which are often indications for surgical intervention. The literature lacks sufficient objective data detailing the complex anatomy and localized osseous landmarks essential for current surgical techniques. This study found that data regarding anatomic attachment sites and distances to bony prominences can optimize current surgical fixation techniques, [...]

Ankle Syndesmosis: A Qualitative and Quantitative Anatomic Analysis

2018-09-25T10:09:16-06:00

Syndesmosis sprains can contribute to chronic pain and instability, which are often indications for surgical intervention. The literature lacks sufficient objective data detailing the complex anatomy and localized osseous landmarks essential for current surgical techniques. This study found that the qualitative and quantitative anatomy of the syndesmotic ligaments was reproducibly described and defined with respect to [...]

Radiographic Identification of the Primary Lateral Ankle Structures

2018-09-25T10:09:16-06:00

Lateral ankle ligament injuries rank among the most frequently observed athletic injuries, requiring repair or reconstruction when indicated. However, there is a lack of quantitative data detailing the ligament attachment sites on standard radiographic views. This study found that radiographic parameters quantitatively describing the anatomic origins and insertions of the lateral ankle ligaments were defined [...]

Normative Rearfoot Motion During Barefoot and Shod Walking Using Biplane Fluoroscopy

2018-02-22T12:06:43-06:00

The ankle rearfoot complex consists of the ankle and subtalar joints. This is an observational study on two test conditions of the rearfoot complex. Using high-speed biplane fluoroscopy, we present a method to measure rearfoot kinematics during normal gait and compare rearfoot kinematics between barefoot and shod gait. This study found that biplane fluoroscopy can [...]

Diagnostic Accuracy of 3.0 Tesla Magnetic Resonance Imaging for the Detection of Articular Cartilage Lesions of the Talus

2018-02-22T12:06:43-06:00

Talar chondral defects can be a source of persistent ankle pain and disability. If untreated, there is an increased risk of osteoarthritis. The purpose of our study was to determine diagnostic accuracy of 3T MRI in detecting Outer bridge grades 3 and 4 articular cartilage lesions of the talus in a clinical setting, utilizing a [...]

The Ligament Anatomy of the Deltoid Complex of the Ankle: A Qualitative and Quantitative Anatomical Study

2018-02-22T12:06:44-06:00

The deltoid ligament has both superficial and deep layers and consists of up to six ligamentous bands. The prevalence of the individual bands is variable, and no consensus as to which bands are constant or variable exists. Although other studies have looked at the variance in the deltoid anatomy, none have quantified the distance to [...]

Anterior Talofibular Ligament Ruptures, Part 2: Biomechanical Comparison of Anterior Talofibular Ligament Reconstruction Using Semitendinosus Allografts With the Intact Ligament

2018-02-22T12:06:44-06:00

Anatomic reconstructions of the lateral ankle ligaments with grafts have been proposed for patients with generalized ligamentous laxity, long-standing instability with attenuated native tissues, varus hindfoot misalignment, or failed prior lateral ligament surgery and for very large patients or elite athletes because of increased demands. This study found that anatomic reconstruction of the ATFL with [...]

Anterior Talofibular Ligament Ruptures, Part 1: Biomechanical Comparison of Augmented Broström Repair Techniques with the Intact Anterior Talofibular Ligament

2018-02-22T12:06:44-06:00

The concept of utilizing nonabsorbable suture tape fixed directly to bone to augment Brostrom repairs of the anterior talofibular ligament (ATFL) has been proposed. No biomechanical studies of this technique are available. We hypothesized that suture tape augmentation alone and Brostrom repair with suture tape augmentation would have similar biomechanical properties to the intact ATFL at [...]

Radiographic Identification of the Primary Structures of the Ankle Syndesmosis

2018-02-22T12:06:44-06:00

The purpose of this study was to quantitatively describe the locations of the syndesmotic ligaments and the tibiofibular articulating cartilage surfaces on standard radiographic views using reproducible radiographic landmarks and reference axes. Quantitative radiographic guidelines describing the locations of the primary syndesmotic structures demonstrated excellent reliability and reproducibility. Defined guidelines provide additional clinically relevant information regarding [...]
