PURPOSE The purposes of this study were to identify differences in the biomechanical and biochemical properties among the articulating surfaces of the ankle joint and to evaluate the functional and biological properties of engineered neocartilage generated using chondrocytes from different locations in the ankle joint. METHODS The properties of the different topographies within the ankle join...

Fractures of the talus are uncommon. The relative infrequency of these injuries in part accounts for the lack of useful and objective data to guide treatment. The integrity of the talus is critical to normal function of the ankle, subtalar, and transverse tarsal joints. Injuries to the head, neck, or body of the talus can interfere with normal coupled motion of these joints and result in perman...

Talar compression fractures are uncommon orthopaedic injuries, especially in the immature skeleton. Fractures of the talar body constitute >5% of all foot and ankle fractures. The combination of a medial compression fracture and corresponding medial malleolar fracture is rare and not previously reported injury in the literature. We present a case report of a skeletally immature 15-year-old Cauc...

OBJECTIVE To evaluate the clinical, functional and radiographic results from talar neck fractures in patients treated at the Foot and Ankle Surgery Group of Santa Casa de Sao Paulo. METHOD We evaluated 20 patients. The mean follow-up time was 71 months. One fracture was classified as Hawkins Type I, 12 as Hawkins type II, five as Hawkins type III, two as Hawkins type IV and four fractures wer...

BACKGROUND AND PURPOSE A metallic inlay implant (HemiCAP) with 15 offset sizes has been developed for the treatment of localized osteochondral defects of the medial talar dome. The aim of this study was to test the following hypotheses: (1) a matching offset size is available for each talus, (2) the prosthetic device can be reproducibly implanted slightly recessed in relation to the talar carti...

PURPOSE The purpose of this systematic review was to determine patient outcomes after arthroscopic debridement and microfracture for osteochondral lesions (OCLs) of the talar dome. METHODS Infotrieve-PubMed/MEDLINE and Google Scholar were systematically searched for the following terms: microfracture AND ankle OR talus. In addition, we hand-searched common American and European orthopaedic an...
