Total Ankle Replacement (TAR) could, in theory, partially restore joint sensation and motion, enhancing motor coordination, functional stability, and proprioception in a joint affected by osteoarthritis. The aim of this study is to evaluate ankle proprioception before and after a Total Ankle Replacement via an instrumental objective assessment. The evaluation of proprioceptive stability was carried out using the dedicated Delos Postural Proprioceptive System (DPPS). The clinical evaluation was performed by administering validated questionnaires, namely the American Orthopaedic Foot and Ankle Society (AOFAS) score and Short Form-36 (SF-36). Twenty patients were selected, undergoing a complete procedure with clinical and instrumental pre-operative and post-operative evaluation at the end of the follow-up. AOFAS ankle–hindfoot and SF-36 both showed a statistically significant improvement between the pre-operative and post-operative state. The postural tests performed using the DPPS showed that the affected limb showed results slightly lower than in pre-operative. In conclusion, according to the current data, the TAR does not show an improvement in proprioceptive joint stability, and although the registered mean values do not present a statistical significance, the stabilometry shows data lower than the healthy limb. In this perspective, further studies are recommended to highlight any rehabilitation scheme or protocols, using wider case series.
