Reliability of the Phi angle to assess rotational alignment of the talar component in total ankle replacement

End stage ankle osteoarthritis (OA) is a chronic disease associated with mental and physical disability at least as severe as that associated with end-stage hip OA [1]. In the last decades, total ankle arthroplasty (TAA) has progressed as a treatment option in patients with ankle OA [2,3]. Total ankle replacement (TAR) has a learning curve [4,5]. The correct positioning of the talar component is one of the most demanding steps, especially in patients with valgus or varus hindfoot deformities. The primary goals when performing a total ankle arthroplasty is to restore a physiologic sagittal and coronal axis for the long-term survival of the implants.
