Ankle sprain is amongst the most frequent musculoskeletal injuries, particularly during sports activities. Chronic ankle instability (CAI) resulting from an ankle sprain might have severe long-lasting consequences on the ankle joint. Despite the fact that most patients will respond favourably to appropriate conservative treatment, around 20% will develop symptomatic CAI with sense of giving away and recurrent sprains leading to functional impairment. "Classical" surgical repair by Brostrom-like surgery in one of its many modifications has achieved good results over the years...

Peroneal intrasheath instability is a painful snapping condition of the lateral ankle. It consists of a transient retromalleolar subluxation of the peroneal tendons without disruption of the superior peroneal retinaculum or evidence of a previous definite trauma. In type A intrasheath instability, the peroneus longus and brevis tendons are intact, and there is an intertendinous intrasheath switch. In type B intrasheath instability, the peroneus brevis tendon has a longitudinal split tear through which the peroneus longus subluxates...

PURPOSE: To evaluate the difference between T2 relaxation values of the subtalar cartilage in lateral ankle instability patients and healthy volunteers. MATERIALS AND METHODS: This institutional review board-approved study included 27 preoperative magnetic resonance imaging (MRI) examinations of 26 patients who underwent Broström operations. Data of previously enrolled healthy volunteers (12 volunteers, 13 MRIs) were used as controls. Two radiologists independently measured T2 values in eight posterior subtalar joint cartilage compartments: central calcaneus anterior (CCA) and posterior (CCP), central talus anterior (CTA) and posterior (CTP), lateral calcaneus anterior (LCA) and posterior (LCP), and lateral talus anterior (LTA) and posterior (LTP)...

Evaluation and management of ankle fractures has progressed in parallel to an evolving understanding of ankle stability. While stability of the mortise had historically been attributed to the lateral malleolus, Lauge-Hansen's contributions followed by multiple other investigations increased the emphasis on the significance of medial-sided injury in destabilizing the mortise. As the importance of the deltoid ligament has been elucidated, the means of assessing ligamentous incompetence and the prognostic significance of an unstable mortise continue to be defined...

Lateral Ankle sprain (LAS) is a common sports injury associated with recurrent ankle sprain, chronic ankle instability (CAI) and post-traumatic ankle osteoarthritis (PTOA). Platelet Rich Plasma (PRP) has been increasingly used for herapeutic applications in sports-related injuries, and is thought to stimulate tissue healing. We reported a case of LAS with complete tear of anterior talofibular ligament, which showed complete healing of ligament and early ankle stabilization after PRP. The healing is supported by dynamic ultrasound images and magnetic resonance imaging...

Fractures of the lateral process of the talus are uncommon, but often overlooked. They can result in significant functional deficit with residual nonunion and arthritis if not recognized and treated appropriately. We describe 2 cases of such injuries, one with acute recognition and management, and one with delayed diagnosis and nonunion. In both cases, pain from the fracture was accompanied by symptoms of instability requiring simultaneous lateral ligament reconstruction along with fracture fixation. Evaluation of patients with lateral process fractures should include assessment of the lateral ligaments; ankle instability may need to be surgically addressed along with intervention for fracture fixation...

BACKGROUND: Previous studies have reported the factors contributing to chronic ankle instability, which could lead to more effective treatments. However, factors such as the reflex response and ankle muscle strength have not been taken into account in previous investigations. METHODS: Fifty recreational athletes with chronic ankle instability and 55 healthy controls were recruited. Peroneal reaction time in response to sudden inversion, isokinetic evertor muscle strength and dynamic balance with the Star Excursion Balance Test and the Biodex Stability System were measured...

Ankle and foot injuries are common among athletes and physically active individuals. The most common residual disability, ankle sprain, is characterized by instability along with postural sway. If the supporting structures around a joint become lax, posture stability and balance are also affected. Previous studies have examined muscle stiffness and elasticity and postural sway separately; however, the relationship between these factors is yet unknown. It is well known that the levels of sex hormones, especially estrogen, change in women over the phase of the menstrual cycle...

BACKGROUND: An acute ankle sprain can result in a bony avulsion of the lateral ankle ligaments. The extent of concomitant lesions and subsequent instability patterns are not clearly understood. The high incidence of old avulsion fractures found in symptomatic chronic ankle instability may indicate the need for primary fixation. METHODS: Ten patients (5 male, 5 female; mean age, 34 years; range, 15-64 years) with bony avulsion fractures of the fibula after acute ankle sprains were included...

Standing on unstable surfaces requires more complex motor control mechanisms to sustain balance when compared to firm surfaces. Surface instability enhances the demand to maintain equilibrium and is often used to challenge balance, but little is known about how balance training affects movement strategies to control posture while standing on unstable surfaces. This study aimed at assessing the effects of isolated wobble board (WB) training on movement strategies to maintain balance during single-leg standing on a WB...

Surgical procedures for managing chronic lateral ankle instability include anatomic direct repair, anatomic reconstruction with an autograft or allograft, and arthroscopic repair. Open direct repair is commonly used for patients with sufficient ligament quality. Reconstruction incorporating either an autograft or an allograft is another promising option in the short term, although the longevity of this procedure remains unclear. Use of an allograft avoids donor site morbidity, but it comes with inherent risks...

INTRODUCTION: Chronic lateral ankle instability occurs in up to 20% of ankle injuries. Most can be treated conservatively, but surgical reconstruction is required if conservative treatment fails. Modified Broström-Gould procedure is an effective surgical treatment and the augmentation of this procedure with a periosteal flap may confer additional stability. We report on the outcome of a technique combining a modified Broström-Gould procedure augmented with a periosteal flap in patients with chronic lateral ankle instability...
