Core Tip
Core Tip: Our aim was to provide an overview of the clinical efficacy of a novel implant system that is a hemi-arthroplasty of the ankle. This device can be used for multiple, secondary osteochondral lesions of the talus and isolated osteo-arthritis of the talar dome. In this prospective case series, it was shown that this novel device showed promising clinical outcomes and can be considered safe.
