Chronic ankle instability

INTRODUCTION: After an ankle sprain, up to 20% of patients may develop chronic lateral ankle instability (CLAI) requiring surgical treatment. The objective of this study was to investigate the functional outcomes and rates of return to sport activities in a cohort of non-athlete patients with chronic lateral ankle instability (CLAI) who underwent the opened Brostrom-Gould technique (BGT). MATERIALS AND METHODS: Seventy-nine patients (seventy-nine feet) from three different centers undergoing BGT were reviewed...

Chronic ankle instability (CAI) is a common injury that can occur in daily life or sporting events. Injuries to the anterior talofibular, posterior talofibular, and calcaneofibular ligaments are common, and the core of rehabilitation training involves strengthening the peroneus muscle. Many studies on rehabilitation training have focused on strengthening the peroneus brevis muscle, and few studies have focused on specific training to strengthen the peroneus longus muscle. Therefore, this study aims to investigate changes in the symptoms and functions of patients by applying training to strengthen the peroneus longus and peroneus brevis muscles...

The purpose of this study was to calculate and compare (1) knee loads, (2) muscle-specific contributions to knee loads, and (3) effects of knee flexion angle on knee loads and muscle-specific load contributions during a forward jump-landing task in people with and without chronic ankle instability (CAI). Eight CAI patients and seven healthy controls performed a forward jump-landing task. We collected 3D kinematics, ground reaction force, and muscle activation and used musculoskeletal modeling. The results showed that only healthy controls exhibited an association between knee flexion angle and knee compressive impulse ( r  = 0...

OBJECTIVE: This study investigated the effect of neuromuscular electrical stimulation (NMES) on the frontal ankle motor control in individuals with chronic ankle instability (CAI) during drop-landing. DESIGN: This was a randomized, controlled, double-blind trial. Thirty-six individuals with CAI were randomly assigned to each group. Participants received 6-week NMES intervention and sham stimulation in the NMES and control groups, respectively. Data was collected at week0 and week6...

BACKGROUND: It has been shown that chronic ankle instability (CAI) leads to abnormalities in neuromuscular control of more proximal joints than the ankle. Although strength of the hip and the ankle muscles has been largely investigated providing concordant results, limited evidence with contrasting results has been reported regarding knee extensor and flexor muscles. PURPOSE: To investigate maximal and submaximal isometric muscle strength in individuals with CAI...

BACKGROUND: Generalized joint laxity (GJL) is a risk factor for inferior outcomes after the modified Broström procedure for chronic lateral ankle instability, while anatomic reconstruction with tendons is more inclined to be recommended. However, whether anatomic reconstruction could achieve better results than the modified Broström procedure in patients with GJL is unknown. PURPOSE: To compare clinical outcomes and return to sports between anatomic reconstruction and the modified Broström procedure in patients with GJL...

BACKGROUND: Lateral ankle sprain (LAS) is the most common sports injury, leading to a high rate of recurrence and the development of chronic ankle instability. One possible explanation is the lack of objective, evidence-based criteria to inform return to sport decisions following LAS. The aim of this study was therefore to assess the efficacy of a new functional score to distinguish patients at risk of recurrent LAS within two years after the initial injury. METHODS: The Ankle-GO score was used in 64 active patients two months after LAS...

BACKGROUND: This study aimed to investigate the prevalence of radiographic ankle osteoarthritis (AOA) in Japan and identify its risk factors. METHODS: The analysis included data from the population-based cohort study, radiographs of the knees and ankles, ultrasonography of the ankle to examine chronic ankle instability (CAI), and questionnaires on ankle pain, job history, height, and body weight. A total of 597 individuals aged > 50 years were included in the study...

CONTEXT: Repeated ankle sprains can lead to injuries, including those of the anterior talofibular ligament; however, the extent to which these ligament injuries are associated with symptoms of chronic ankle instability remains unclear. OBJECTIVE: To examine the influence of anterior talofibular ligament injury and ankle anterior displacement on symptoms of chronic ankle instability. DESIGN: Case-Control Study. SETTING: A university laboratory...

OBJECTIVES: This study aimed to determine the incidence rate and characterise the location and severity of cartilage lesions in the ankle in elite athletes undergoing suture-button stabilisation for unstable distal syndesmotic injuries using needle arthroscopic examination. The feasibility and safety of ad hoc needle arthroscopy and its assisted interventions were also assessed. METHODS: This prospective case series included elite athletes undergoing surgical stabilisation between April 2021 and June 2023...

INTRODUCTION: Lateral ankle sprain is the most common ankle injury and up to 40% of those who sustain a lateral ankle sprain will develop chronic ankle instability (CAI). The aim of this study was to explore the thoughts and expectations of CAI-patients concerning their condition and expectations of care in an orthopedic setting. . STUDY DESIGN: Qualitative study. METHODS: Nine semi-structured one-to-one interviews were conducted with CAI-patients who were referred to an orthopedic setting...

In recent years, anterior tibiofibular ligament-distal fascicle transfer for anterior talofibular ligament augmentation repair have proposed. However, a comprehensive biomechanical study on the anterior tibiofibular ligament-distal fascicle transfer is still lacking. We are established four distinct groups, namely the normal, the anterior talofibular ligament rupture, the anterior talofibular ligament repair, and the anterior talofibular ligament repair + anterior tibiofibular ligament-distal fascicle transfer...

This review article discusses the current evidence on the management of chronic syndesmotic instability. Conservative treatment has a limited role, and surgical intervention is most commonly reported as the mainstay of treatment, however the literature consists of small case series and descriptions of operative techniques, and thus the evidence base for any treatment is weak. Surgical options include arthroscopic debridement alone, static fixation with cortical screws, dynamic fixation with suture-button devices, and ligamentous repair or augmentation...

INTRODUCTION: The Reactive Balance Test (RBT) could be a valuable addition to research on chronic ankle instability (CAI) and clinical practice, but before it can be used in clinical practice it needs to be reliable. It has already been proven reliable in healthy recreational athletes, but not yet in patients with CAI who have shown persistent deficits in dynamic balance. The study aimed to determine the test-retest, intra-, and inter-rater reliability of the RBT in patients with CAI, and the test-retest and inter-rater reliability of the newly developed RBT score sheet...

BACKGROUND: Individuals with chronic ankle instability often present with clinical and biomechanical abnormalities, however squat biomechanics have not been investigated. The purpose of this study was to compare select clinical assessments and squat biomechanics between individuals with and without chronic ankle instability. METHODS: Fifteen individuals with chronic ankle instability and a matched control group were studied. A weight-bearing dorsiflexion lunge test, foot posture, and an in-line half-kneeling motor control test for core stability were assessed...

BACKGROUND: Ankle muscle strength should be assessed after a lateral ankle sprain (LAS) because a strength deficit can lead to chronic ankle instability (CAI). No field method is available to obtain quantitative ankle dynamic strength values. This study aimed to assess the reliability of the one-repetition maximal (1-RM) method and to compare ankle muscle strength between healthy volunteers and those with CAI using 1-RM strength assessment approach. METHODS: We recruited 31 healthy volunteers and 32 with CAI...

OBJECTIVE: Ankle injuries in delivery workers (DWs) are often caused by trips, and high recurrence rates of ankle sprains are related to chronic ankle instability (CAI). Heel rise requires joint angles and moments similar to those of the terminal stance phase of walking that the foot supinates. Thus, our study aimed to develop, determine, and compare the predictive performance of statistical machine learning models to classify DWs with and without CAI using ankle kinematics during heel rise...

CONTEXT: Researchers have shown that patients with chronic ankle instability (CAI) have deficits in memory and attention allocation. This functional deficit affects the lower extremity performance. Motor-cognitive dual-task training may improve lower limb dysfunction caused by central nervous system injury. Whether dual-task training is more favorable than single-task training for neuromuscular control in patients with single-task training still needs to be further proven. OBJECTIVE: To determine whether balance-cognitive dual-task training can influence cortical activity and has more effective treatment effects than balance single-task training...

Background and Objectives: This study aimed to evaluate the effects of subtalar joint axis-based balance exercises on the anterior talofibular ligament (ATFL) thickness, ankle strength, and ankle stability after an arthroscopic modified Broström operation (AMBO) for chronic ankle instability (CAI). Materials and Methods: The study included 47 patients diagnosed with CAI who underwent AMBO and were randomly divided into three groups: control ( n = 11), general balance exercise ( n = 17), and subtalar joint axis balance exercise ( n = 19), regardless of the affected area...

BACKGROUND: Several demographic and clinical risk factors for recurrent ankle instability have been described. The main objective of this study was to investigate the potential influence of morphologic characteristics of the ankle joint on the occurrence of recurrent instability and the functional outcomes following a modified Broström-Gould procedure for chronic lateral ankle instability. METHODS: Fifty-eight ankles from 58 patients (28 males and 30 females) undergoing a modified Broström-Gould procedure for chronic lateral ankle instability between January 2014 and July 2021 were available for clinical and radiological evaluation...
