Chronic ankle instability

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...

First-time lateral ankle sprains often lead to chronic ankle instability (CAI), with 47% facing recurrent injuries, emphasizing the need for preventive measures. Side-cutting movements in sports pose a risk for CAI individuals due to potential biomechanical control alterations. While the hop-stabilization warm-up program has proven effective in preventing ankle sprains, its specific acute impact on CAI individuals lacks substantial evidence. This study employed a crossover design with eight CAI participants (23 ± 3...

BACKGROUND: Ankle osteoarthritis (OA) mainly arises from trauma, particularly lateral ligament injuries. Among lateral ligament injuries, ankles with calcaneofibular ligament (CFL) injuries exhibit increased instability and can be a risk factor ankle OA progression. However, the relationship between CFL injury and OA progression remains unclear. Therefore, this study aims to assess the relationship between CFL injuries and ankle OA by investigating stress changes and osteophyte formation in subtalar joint...

Purpose: The effects of the combination of strength training and acupuncture on chronic ankle instability have not been studied. This study examined effects of strength training combined with acupuncture on balance ability, ankle motion perception, and muscle strength in chronic ankle instability among college students. Methods: Forty-six chronic ankle instability college students were randomly categorized into the experimental group (n = 24, strength training + acupuncture) and the control group (n = 22, strength training) for an 8-week intervention...

BACKGROUND: Individuals with chronic ankle instability (CAI) may experience recurrent ankle sprains and symptoms during daily activities such as stair descent, where the associated proprioceptive deficit is largely unevaluated. OBJECTIVES: To evaluate the reliability and validity of an ankle inversion discrimination apparatus for stair descent, and examine whether proprioceptive scores from this apparatus are associated with patient-reported symptoms. DESIGN: Cross-sectional study...

BACKGROUND: Some children and adolescents can develop persistent pain and instability following inversion injuries of the ankle. In these cases, imaging exams could reveal small bone fragments distal to the lateral malleolus. For these patients, regular conservative treatment may not be successful, requiring additional management, which can include surgical treatment. This study aimed to present the short-to-midterm functional and clinical outcomes of a series of 12 pediatric and adolescent patients who underwent ligament repair surgery due to chronic instability associated with the presence of osseous components in the lateral ligaments...

BACKGROUND: Athletes engaged in sports dance frequently encounter the potential for ankle injuries and instability, factors that may contribute to diminished training efficacy, compromised athletic performance, prolonged recuperation, and heightened susceptibility to recurring injuries. OBJECTIVE: The objective of this study was to investigate the impact of an exercise intervention (comprising blood flow restriction training combined with low-load ankle muscle strength training and balance training) as well as instrument-assisted soft tissue mobilization (IASTM) on the foot and ankle function, strength, and range of motion in sports dance athletes exhibiting ankle instability (CAI)...

BACKGROUND: Perceived instability is a primary symptom among individuals with chronic ankle instability. However, the relationship between joint kinematics during landing remains unclear. Therefore, we investigated the relationships between landing kinematics and perceived instability in individuals with chronic ankle instability. METHODS: In 32 individuals with chronic ankle instability, we recorded ankle, knee, and hip joint angles during a single-leg drop landing...

BACKGROUND: Ankle sprains lead to an unexplained reduction of ankle eversion strength, and arthrogenic muscle inhibition (AMI) in peroneal muscles is considered one of the underlying causes. This study aimed to observe the presence of AMI in peroneal muscles among people with chronic ankle instability (CAI). METHODS: Sixty-three people with CAI and another sixty-three without CAI conducted maximal voluntary isometric contraction (MVIC) and superimposed burst (SIB) tests during ankle eversion, then fifteen people with CAI and fifteen without CAI were randomly invited to repeat the same tests to calculate the test-retest reliability...

AIM: To identify the effects of strength and balance training on dynamic balance and patient reported outcomes in people with chronic ankle instability(CAI). METHOD: Five databases(CNKI, WanFang, Web of Science, EBSCO-SPORTD and PubMed were searched in September 2022. The search was conducted on randomized controlled trials(RCTs) that the effects of strength training, balance training and combination of strength and balance training in people with chronic ankle instability compared to a control group...

BACKGROUND: Chronic ankle instability (CAI) is associated with changes in gait biomechanics which may be related to chronic dysfunction. Traditional statistical models may be limited in their ability to assess the complex 3D movement of the lower extremity during gait. Multivariate analysis of the lower extremity kinematics may reveal unique biomechanical differences associated with CAI. RESEARCH QUESTION: Do patients with CAI differ from healthy controls in their lower extremity biomechanics and GRF when comparing 3D biomechanics? METHODS: Thirty-nine young, active adults participated in this study...

BACKGROUND: The lateral ankle joint comprises the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL). The purpose of this study was to propose a classification of CFL morphology. METHODS: The material comprised 120 paired lower limbs from human cadavers (30 male, 30 female), mean age 62.3 years. The morphology was carefully assessed, and morphometric measurements were performed. RESULTS: A 4-part method for anatomic classification can be suggested based on our study...

BACKGROUND: Chronic ankle instability (CAI) is manifested by sensorimotor impairments in the sprained ankle, including deficits in sensation, motor function, and central integration or processing. These impairments have a significant impact on physical activities and daily life. Recently, some studies have suggested that bilateral deficits were observed in unilateral CAI, but contradictory evidence disputes this finding. Therefore, the objective of this study was to investigate whether bilateral sensorimotor deficits presented in individuals with unilateral CAI...
