BACKGROUND: Articular cartilage lesions of the talus remain a challenging clinical problem because of the lack of natural regeneration and limited treatment options. Microfracture is often the first-line therapy, however lesions larger than 1.5 cm2 have been shown to not do as well with this treatment method. METHODS: The objective of this retrospective study was to evaluate the outcomes of iliac crest bone marrow aspirate concentrate/collagen scaffold (ICBMA) and particulated juvenile articular cartilage (PJAC) for larger articular cartilage lesions of the talus...

BACKGROUND: Single Photon Emission Computed Tomography-Computed Tomography (SPECT/CT) gains an important part of diagnostics in patients with osteochondral lesions (OCL). SPECT/CT is a hybrid imaging modality, which combines a 3D scintigraphy (SPECT) and computerized tomography (CT) into one single procedure and combines metabolic data, structural and mechanical information. The purpose of the study was to develop and evaluate a standardized method to anatomically localize and quantitatively analyze the bone SPECT tracer activity of the ankle joint using SPECT/CT...

The incidence of revision of total ankle replacement prostheses remains unclear. We undertook a systematic review to identify the material relating to the incidence of revision after implantation of the Salto(®) mobile version and Salto Talaris™ total ankle prostheses. Studies were eligible for inclusion only if they had involved primary total ankle replacement with these prostheses and had included the incidence of revision. Eight studies involving 1,209 Salto(®) mobile version prostheses, with a weighted mean follow-up period of 55...

Juvenile osteochondritis dissecans of the talus (JODT) affects the subchondral bone primarily and, in a skeletally immature population, articular cartilage secondarily. It probably consists of aseptic bone necrosis whose spontaneous healing is impaired by microtraumas, resulting in an osteochondral injury and, in some cases, in osteoarthritis. In many cases the clinical presentation is asymptomatic. Mild chronic pain is frequent, sometimes accompanied by swelling, stiffness or locking. Few data are currently available on this topic and, moreover, most existing data were obtained from mixed groups and populations; it is therefore difficult to outline a scheme for the treatment of JODT...

PURPOSE: The purpose of this study was to compare the clinical and magnetic resonance imaging (MRI) outcomes of arthroscopic microfracture surgery alone or in combination with hyaluronic acid (HA) injection in the treatment of osteochondral lesions of the talus. METHODS: Thirty-five patients with osteochondral lesions of the talus who underwent arthroscopic microfracture were included and followed up for at least 9 months post-operatively. The patients were randomly divided into non-injection group (n = 17) who received treatment with microfracture surgery alone and injection group (n = 18) who also accepted intra-articular injection of HA post-operatively...

BACKGROUND: Osteochondral ankle injuries commonly affect the dome of the talus, and these injuries are a common cause of athletic disability. Various treatment options are available for these injuries including intra-articular hyaluronic acid (HA) and platelet-rich plasma (PRP) injections. The purpose of this study was to compare the effects of HA and PRP as adjunct therapies after arthroscopic microfracture in osteochondral lesions (OCLs) of the talus. METHODS: In this prospective, randomized blinded study, 40 patients with talar OCLs in their ankle joints were treated with arthroscopic debridement and a microfracture technique...

PURPOSE OF THE STUDY: Total talar extrusion is a rare injury. It is frequently associated with severe soft tissue injury. There is no consensus about an appropriate treatment for an extruded talus. Total extrusion of the talus has a high possibility of avascular necrosis of the talus or infection. The primary goal of this study is a retrospective evaluation of the patients with open total talar dislocation treated by immediate reimplantation. MATERIALS AND METHODS: We evaluated six patients (mean age, 29...

Osteochondroma occurs most frequently in the long bones such as the proximal humerus, tibia, and distal femur. It is rare for it to originate in the talar neck. In the present case report, we describe a case of osteochondroma arising from the talar neck. Furthermore, a review of the published studies of talar osteochondroma was performed to obtain a better understanding of the symptoms, diagnosis, and treatment of this unusual entity.

The talus is the most proximal bone of the hindfoot that couples the foot to the leg. It is the second most common fracture of the tarsal bones, second in frequency to the calcaneous. However, overall injuries to the talus are relatively rare, and most surgeons have little experience in managing them. This article discusses fractures of the talus, including injuries to the talar neck, body, head, and processes. Although subtalar dislocations and osteochondral injuries are important topics, they are not addressed in this article...

BACKGROUND: Talar chondral defects can be a source of persistent ankle pain and disability. If untreated, there is an increased risk of osteoarthritis. The purpose of our study was to determine diagnostic accuracy of 3T MRI in detecting Outerbridge grades 3 and 4 articular cartilage lesions of the talus in a clinical setting, utilizing a standardized clinical MRI protocol. METHODS: Patients who had a 3T ankle MRI and subsequent ankle surgery, by a single surgeon, were included in this study...

UNLABELLED: Osteochondral lesions of the talus (OLT) are commonly associated with traumatic injury to the ankle joint. Treatment options depend on the grade, location, and size of the lesion. Operative intervention is frequently required with initial management involving marrow stimulation techniques, such as microfracture/curettage. Larger lesions often require a secondary procedure, such as osteochondral transplantation or autologous chondrocyte implantation. The advent of particulated juvenile articular cartilage (PJAC) provides an alternative method for OLTs refractory to traditional treatments...

BACKGROUND: The early diagnosis of avascular necrosis of the talus (AVN) and prediction of ankle function for talar fractures are important. The Hawkins sign, as a radiographic predictor, could exclude the possibility of developing ischemic bone necrosis after talar neck fractures, but its relationship with ankle function remains unclear. The purpose of this study was to illustrate the prognostic effect of the Hawkins sign on ankle function after talar neck fractures and to study the value of early MRI in detecting the AVN changes after talus fractures...

BACKGROUND: Osteochondral lesions of the talar dome (OLT) involve the articular cartilage and/or subchondral bone. The subchondral bone plate plays an important role in cartilage metabolism. We hypothesized that the findings of subchondral bone on CT image would be related to the cartilage damage of OLT. The purpose of this study was to evaluate the relationship between the arthroscopic and CT findings focused on subchondral bone. METHODS: Thirty-one ankles diagnosed as OLT were analyzed...

BACKGROUND: Large talar cartilage defects can be treated with either autologous chondrocyte implantation or matrix autologous chondrocyte implantation. Both techniques depend on successful harvesting of the chondrocytes. In the past, they have come from the ipsilateral knee, which has been associated with donor site morbidity. We hypothesized that damaged cartilage from the talus can be used as a reliable source for chondrocyte cell harvesting in preparation for possible matrix-induced autologous chondrocyte implantation (MACI)...

BACKGROUND: Few reports have studied the treatment of osteochondral lesions of the talus (OLTs) in the setting of lateral ankle instability. HYPOTHESIS: Arthroscopic treatment of an OLT and lateral ankle stabilization in the same sitting is safe and leads to reliable improvement of symptoms. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Of 37 patients who underwent concomitant treatment of an OLT and lateral ankle stabilization, 31 (84%) were evaluated at a mean of 7...
