Lateral soft tissue release with distal chevron metatarsal osteotomy in moderate and severe hallux valgus.

The purpose of this study was to evaluate the radiographic outcomes of distal chevron metatarsal osteotomy associated with lateral joint capsule split as only lateral soft tissue release in patients with symptomatic moderate and severe hallux valgus (HV) deformity. Ninety patients (103 feet) at our institution between January 2014 and December 2019 were included in the present retrospective study. Each patient was evaluated preoperatively and at final follow-up by means of weight bearing radiographs lateral and dorsoplantar views.

New Classification System for Proximal Fifth Metatarsal Fractures: Intraobserver and Interobserver Reliability Assessment.

Background: The most commonly used classification for proximal fifth metatarsal fractures has not shown good reproducibility. The aim of this study was to evaluate the intraobserver and interobserver agreement of a new classification system for such fractures.

Methods: The study involved the development of a novel classification system that categorized these fractures into 2 main types and 2 subtypes.

Arthroscopic Anatomic Reconstruction of the Anterior Talofibular and Calcaneofibular Ligaments Through a 2-Portal Technique.

Arthroscopic anatomic lateral ligament reconstruction of the ankle joint has proven to be a safe option in the treatment of chronic ankle instability (CAI), with good functional results as well as allowing simultaneous management of associated lesions. We described an arthroscopic technique for anatomic reconstruction of the anterior talofibular ligament and calcaneofibular ligament using only 2 arthroscopic portals. This surgical technique to treat CAI is technically less demanding than other described techniques that use 3 or 4 arthroscopic portals.

Results of Anatomical Arthroscopic Repair of Anterior Talofibular Ligament in Chronic Lateral Ankle Instability Patients.

Background: To assess the clinical and functional outcomes of all-inside arthroscopic anatomical repair of anterior talofibular ligament (ATFL) for management of chronic lateral ankle instability (CLAI) in a considerable number of patients during medium-term follow-up.

Methods: A retrospective analytic study was performed on 100 patients with CLAI who presented between August 2015 and July 2020 (average age: 32.9 years; range: 16-54 years).

Reconstruction of the interosseous talocalcaneal ligament using allograft for subtalar joint stabilization is effective.

Purpose: The aim of this study was to assess the biomechanical effects of subtalar ligament injury and reconstruction on stability of the subtalar joint in all three spatial planes.

Methods: Fifteen fresh frozen cadaveric legs were used, with transfixed tibiotalar joints to isolate motion to the subtalar joint. An arthrometer fixed to the lateral aspect of the calcaneus measured angular displacement in all three spatial planes on the inversion and eversion stress tests.

Increased subtalar rotational motion in patients with symptomatic ankle instability under load and stress conditions.

Purpose: Differentiating subtalar and ankle instability in the clinical setting is challenging. This study aims to analyze the rotational laxity of the subtalar joint bilaterally in patients with asymptomatic and symptomatic ankle instability under simulated load and stress-induced position of the subtalar joint.

Methods: A case-control study was conducted using an adjustable load device (ALD).

Comparison of Direct Repair Versus Anatomic Graft Reconstruction of the Anterior Talofibular Ligament: A Biomechanical Cadaveric Study.

The goal of our study is to compare the stability of the anatomic reconstruction of the anterior talofibular ligament (ATFL) with direct repair of the ATFL, in a cadaver model. We performed the following techniques in 18 cadaveric ankles: the intact ATFL was cut, after which a direct repair using 2 anchors was performed. The repair was sectioned, and anatomic reconstruction was then performed with a tendon autograft.

Anatomic Arthroscopic Graft Reconstruction of the Interosseous Talocalcaneal Ligament for Subtalar Instability.

Instabilities of the subtalar joint are commonly overlooked or mismanaged, and chronic instability is a debilitating condition leading to premature joint degeneration. Several methods of treatment have been described, mainly screw fixation, arthrodesis, or ligament reconstruction. Most studies describe open methods for ligament reconstruction.

Biomechanical study of autograft anatomic reconstruction in lateral ankle instability.

Introduction: The purpose of this work is perform a biomechanical comparison of anatomic reconstruction of the anterior talofibular ligament (ATFL) with the intact ATFL.

Materials And Methods: We studied 18 fresh cadaveric ankles with intact ATFL. Each specimen was clinically assessed with the anterior drawer (AD) and varus tilt (VT) tests and the angular movement in the three spatial planes (axial, coronal and sagittal) was measured with an arthrometer using a sensor located in the talus.

How to address the posterior malleolus in ankle fractures? A decision-making model based on the computerised tomography findings.

Introduction: The posterior malleolus (PM) is affected in around the 40% of ankle fractures. Anatomical reduction of the articular surface and fibular notch are essential for ankle stability and functional outcomes. These facts justify the increasing interest in the surgical treatment of PM in ankle fractures.

Arthroscopic posterior subtalar arthrodesis for salvage of posttraumatic arthritis following calcaneal fractures.

Background: Subtalar arthrodesis is a treatment option for pain due to posttraumatic arthritis following calcaneal fractures. The goal of this study is to examine the results of arthroscopic subtalar arthrodesis for posttraumatic arthritis following calcaneal fractures.

Patients And Methods: We performed a retrospective case series reviewing 37 consecutive patients (36 male) treated for posttraumatic arthritis following calcaneal fractures by arthroscopic subtalar arthrodesis.

Arthroscopic Subtalar Arthrodesis: Does the Type of Fixation Modify Outcomes?

The goal of the present study was to analyze a modified American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale score, time to union, and the incidence of fusion after isolated arthroscopic posterior subtalar arthrodesis using either 1 or 2 screws of different diameters. We reviewed a consecutive series of 65 patients, mean age 50.0 ± 15.

Anatomical Arthroscopic Graft Reconstruction of the Anterior Tibiofibular Ligament for Chronic Disruption of the Distal Syndesmosis.

Injuries of the distal tibiofibular syndesmosis are commonly overlooked or mismanaged, and chronic instability is a debilitating condition leading to premature joint degeneration. Several methods of treatment have been described, mainly screw fixation, arthrodesis, or ligament reconstruction. Most clinical evidence is limited to case series, mainly screw fixation, and there is a general paucity of evidence regarding ligament reconstruction, which is considered to be more anatomic and to restore joint biomechanics.

All-inside arthroscopic allograft reconstruction of the anterior talo-fibular ligament using an accesory transfibular portal.

Background: Anatomic graft reconstruction of the anterior talo-fibular ligament is an alternative for patients who are bad candidates for standard procedures such as a Broström-Gould reconstruction (high-demand athletes, obesity, hyperlaxity or collagen disorders, capsular insufficiency or talar avulsions). The purpose of this study is to describe an all-inside arthroscopic technique for ATFL reconstruction, and the results in a series of patients with chronic ankle instability.

Methods: We reviewed patients with chronic ATFL ruptures treated with an all-inside arthroscopic allograft reconstruction of the ATFL, with a minimum 2-year follow-up.

Purpose: The goal of this study was to describe the surgical technique and our results with arthroscopic posterior subtalar arthrodesis.

Material And Methods: Retrospective case series of 65 patients (38 men and 27 women) averaging 50 years of age (range 21-72 years) undergoing posterior arthroscopic subtalar arthrodesis using one or two percutaneous 6.5-7.

Clinical results following meniscal sutures: does concomitant acl repair make a difference?

Introduction: The purpose of this study is to analyze the clinical results of meniscal tears repaired with an all-inside suture with special attention to the results in stable versus anterior cruciate ligament (ACL)-deficient knees.

Methods: We studied 45 meniscal tears (32 medial, 13 lateral) repaired in 43 patients using a single all-inside suture system. The patients were divided in two groups and followed-up for at least 12 months.
