OBJECTIVE: Tarsal coalition is known to cause abnormal talocrural stress, hindfoot malalignment, and ankle sprains. These can all be associated with osteochondritis dissecans (OCD) of the talar dome. We present the first detailed description of a series of talar OCDs occurring in patients with tarsal coalition, with the goal of determining whether there is an increased prevalence of OCDs among patients with tarsal coalition. MATERIALS AND METHODS: We studied ankle MRIs in 57 patients with tarsal coalitions, excluding those with a reported inciting traumatic event...

INTRODUCTION: Ankle arthroscopy has come a long way since it was thought, it is not feasible because of tight joint and anatomical characteristics of ankle joint. The same anatomical features like capsular attachment and safe accessory portals are used to access the whole joint even with a rigid arthroscope. Ankle distraction method was routinely used to access the anterior ankle. However, nowadays, anterior arthroscopy is done in dorsiflexion as this increases the anterior ankle joint volume, and thereby easy access to various anatomical structures...

Osteochondral lesions of the talus (OLTs) are characterized by damage to the articular cartilage of the talus and its underlying subchondral bone. Up to 75% of OLTs are caused by trauma, such as an ankle sprain or fracture. Physical examination and imaging are crucial for diagnosis and characterization of an OLT. No superior treatment for OLTs exists. It is paramount that an evidence-based personalized treatment approach is applied to patients with OLTs because lesion and patient characteristics guide treatment...

BACKGROUND: Osteochondral defects of the talus (OCD) are a well-established pathology within the ankle. They are most commonly associated with ankle trauma and whilst many are asymptomatic, they can have a significant negative impact on the patient, most notably with regards pain and mobility. Treatment of these lesions remains variable across the diverse cohort of these patients. AIMS: Evaluating the incidence of talus OCDs. Evaluating anatomic and morphologic data of the lesions against previous studies...

An osteochondral lesion of the talus (OLT) is an idiopathic acquired lesion of the subchondral bone that can lead to debilitating sequelae. The causes of OLT's are still debatable, however, most agree that the etiology is repetitive microtrauma associated with vascular impairment. OLTs are most commonly described in the medial portion of the talus, while lateral involvement is less frequent. If not properly recognized and treated, an OLT may lead to numerous secondary conditions including premature osteoarthritis and functional limitations of the ankle joint...

PURPOSE: ATFL's superior fascicle injury has been considered to be the underlying cause in cases of ankle microinstability. As its clinical diagnosis can be difficult, arthroscopic examination may be the only objective diagnostic tool. The purpose of this study was to determine what types of injuries to the ATFL's superior fascicle are associated with ankle microinstability, and to provide the reader with an arthroscopic classification of the types of microinstability affecting the ankle...

PURPOSE: The purpose of our study was to investigate the performance of MRI findings to predict instability of osteochondral lesion of the talus (OLT) in children and the association between skeletal maturity and lesion stability. MATERIALS AND METHOD: This retrospective IRB-approved and HIPPA-compliant study included children with OLT, who underwent an ankle MRI examination between March 1, 2011, and May 31, 2018. Blinded to the clinical outcome, 2 radiologists retrospectively assessed each MRI study for the presence or absence of various features on the articular side, along the interface, and on the subchondral side of each lesion...

Cryopreserved umbilical cord (UC) allografts have been shown to promote postoperative wound healing by suppressing inflammation and reducing scar formation. The purpose of this study was to determine whether adjunctive use of UC may improve clinical and functional outcomes following arthroscopic repair of talar osteochondral defects (OCDs). A total of 10 patients with talar OCDs that failed nonoperative treatment were enrolled in this single-center, prospective, pilot study. Clinical and functional outcomes were assessed using the Ankle Osteoarthritis Scale (AOS), Foot and Ankle Ability Measure, and Visual Analog Scale (VAS) pain scale at 6, 12, 24, and 52 weeks postoperatively...

BACKGROUND: The cause of osteochondritis dissecans (OCD) is unknown. PURPOSE: To determine if mechanical axis deviation correlates with OCD lesion location in the knee, if degree of mechanical axis deviation correlates with size of OCD lesion, and if the deformity was primarily in the distal femur or proximal tibia. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: We identified 61 knees that underwent osteochondral allograft (OCA) transplantation for femoral condyle OCD lesions and used preoperative lower extremity alignment radiographs to measure lower extremity mechanical axis, mechanical lateral distal femoral angle (mLDFA), mechanical medial proximal tibial angle (mMPTA), and hip-knee-ankle angle...

BACKGROUND: Low vitamin D levels are common in patients with foot and ankle disorders. We have previously demonstrated that juveniles diagnosed with osteochondritis dissecans (OCD) have a high prevalence of vitamin D deficiency. Moreover, there is evidence that OCD might be related to vitamin D deficiency in general. However, whether or not hypovitaminosis D is associated with OCD of the talus has yet to be elucidated. METHODS: The aim of this study was to determine serum vitamin D levels [25(OH)D] of patients diagnosed with traumatic and idiopathic OCD of the talus...

The purpose of this study is to describe, if there is, any relation between ankle morphology and development of talus osteochondritis dissecans (OCD) using certain morphological parameters derived from high resolution magnetic resonance imaging (MRI). Study included a total of 93 patients: 26 patients with traumatic medial talus OCD, 30 patients with idiopathic medial talus OCD and 37 patients with normal ankle as the control group. Five MRI morphological parameters (Maximal Tibial Thickness (MTiTh), Malleolar Width (MalW), Length of Trochlea Tali Arc (TaL), Height of Trochlea Tali Arc (TaH) and Angle of Trochlea Tali Inclination (TaIA)) that are expected to be relevant to talus OCD formation are measured and compared for the three groups...

A rigid surface⁻volume registration scheme is presented in this study to register computed tomography (CT) and free-hand tracked ultrasound (US) images of the talocrural joint. Prior to registration, bone surfaces expected to be visible in US are extracted from the CT volume and bone contours in 2D US data are enhanced based on monogenic signal representation of 2D US images. A 3D monogenic signal data is reconstructed from the 2D data using the position of the US probe recorded with an optical tracking system...

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...
