Chronic lateral ankle instability

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: 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: 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...

PURPOSE: Both the arthroscopic Broström-Gould and Lasso-loop stitch techniques are commonly used to treat chronic lateral ankle instability (CLAI). The purpose of this study is to introduce an arthroscopic one-step outside-in Broström-Gould (AOBG) technique and compare the mid-term outcomes of the AOBG technique and Lasso-loop stitch technique. METHODS: All CLAI patients who underwent arthroscopic lateral ankle stabilization surgery in our department from 2018 to 2019 were retrospectively enrolled...

Surgical repair of acute or chronic lateral instability of the ankle may be unsuccessful in the presence of associated anterior fibulotalar ligament (AFTL) and calcaneofibular ligament (CFL) injury. This Technical Note presents an arthroscopic double-row repair technique of the AFTL associated with suture tape augmentation of the CFL. The patient is in the supine position with the ankle hanging over the edge of the surgical table. The anteromedial portal is created inside the anterior tibial tendon, and the anterolateral portal is created under arthroscopic control...

BACKGROUND: Some patients with lateral ankle sprain (LAS) will experience chronic lateral ankle instability (CLAI). However, not all of those with residual increased lateral ankle laxity (ILAL) become symptomatic. There is a lack of evidence regarding the prevalence of undiagnosed ILAL in the general population. PURPOSE: To evaluate the prevalence of undiagnosed ILAL with the use of stress ultrasonography (US) and to investigate the percentage of ankle sprain copers (ASCs) with ILAL...

PURPOSE: Rotational ankle instability is a multiligamentous injury defined as an overload injury of the deltoid ligament caused by a long-standing injury of the lateral collateral ligament in patients affected by chronic ankle instability. The purpose of the study was to compare the clinical outcomes of combined arthroscopic repair of lateral and medial ankle ligaments for rotational ankle instability versus isolated arthroscopic lateral ligament repair for lateral ankle instability at 2 years' follow-up...

Background: The transfer of the anterior tibiofibular ligament distal fascicle (ATiFL-DF) for the augmentation repair of the anterior talofibular ligament (ATFL) shows potential as a surgical technique. However, evidences on the benefits and disadvantages of this method in relation to ankle joint function are lacking. Purpose: This study aimed to provide comprehensive experimental data to validate the feasibility of ATiFL-DF transfer augmentation repair of the ATFL. Methods: This study included 50 embalmed ankle specimens to measure various morphological features, such as length, width, thickness, and angle, for evaluating similarities between the ATiFL-DF and ATFL...

The lower-extremity kinematics associated with forward jump landing after an ankle injury is known to differ for patients with Chronic Ankle Instability (CAI), copers (injured but asymptomatic patients), and healthy individuals. However, the differences in the lower extremity kinematics of these groups associated with a Single-leg Lateral Drop Landing (SLDL) are unknown. The purpose of this study is to characterize the lower limb and foot kinematics during SLDL in CAI patients and to compare these characteristics with those of the copers and healthy individuals...

BACKGROUND: Chronic Ankle Instability (CAI) is a common musculoskeletal condition characterized by recurring ankle sprains and impaired postural control (PC). Understanding the relationship between ankle muscle strength, PC, and the role of pain is essential for effective management. OBJECTIVES: This prospective cross sectional study aimed to 1. Compare ankle isometric muscle strength (IMS) and PC between CAI and asymptomatic sides. 2. Assess the correlations between ankle IMS and PC and explore the potential mediating effect of pain in individuals with CAI...

CONTEXT: Chronic ankle instability (CAI) is prevalent amongst individuals who sustain a lateral ankle sprain (LAS) injury. The persistent of the characteristic long-standing clinical symptoms of CAI maybe attributable to the lack of adoption of evidence-informed clinical guidelines. OBJECTIVE: To investigate to what extent French-speaking physiotherapists implement the International Ankle Consortium Rehabilitation-Oriented-ASsessmenT (ROAST) framework when providing clinical care for individuals with an acute LAS injury...

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...

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...

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...

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...

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...

BACKGROUND: Posttraumatic osteonecrosis (ON) of the lateral distal tibia is a rare but severe complication of malleolar fractures. Treatment options include ankle fusion, arthroplasty, osteotomy, and drilling but clinical data on outcomes are limited to single case reports. The aim of this study was to prospectively evaluate the outcome following joint-preserving reconstruction. METHODS: Over a 10-year period, 10 patients (8 females and 2 males, average age 36 years; range, 27-68 years) with posttraumatic ON were treated with intra-articular osteotomy of the distal tibia and bone grafting...
