“…In the dynamic evaluation, however, a significant increase in the mean pressure of the non-operated foot was recorded between the pre-and postoperative period, probably due to a compensatory mechanism acting to unload the operated foot. Indeed, the literature reported that the patient achieves a more balanced gait in relation to the gradual progress of rehabilitation [41,44]. Although no significant changes between the pre-and postoperative period were reported, the dynamic evaluation after surgery showed a satisfied peak pressure distribution throughout the feet for many patients, which correlated with the findings reported in the literature, i.e., peak pressure is localized at the level of the calcaneus during the contact phase and at the level of the head of the I metatarsal bone during the intermediate and propulsive support phases [9,11,41,45].…”

Background: Total ankle arthroplasty (TAA) has grown in popularity and indications, with encouraging results over time. Today, preoperative and postoperative evaluations are mainly performed using clinical test and diagnostic imaging, but there is a deficiency in objectively evaluating the biomechanics of the foot and ankle, which serve as the functional markers for monitoring the effectiveness and outcomes of surgery. Inertial measurement units associated with plantar pressure measurements may provide an accurate and reliable method of evaluating function through the analysis of gait and ankle joint mobility. The aim of this study was to introduce an innovative technology, to assess its accuracy and feasibility compared to standard clinical assessment methods and to objectify kinematic outcomes in patients with end-stage ankle OA before and after TAA surgery. Methods: A consecutive series of eight patients with symptomatic end-stage osteoarthritis and treated with TAA was prospectively evaluated using clinical scores (AOFAS, MOxFQ, VAS, SF-36, 17-IFFI), physical tests (FPI, ALT), plantar pressure measurements with FLEX EPS/R2 Letsense® baropodometric platform, gait analysis and wearable sensors-based ankle motion and kinematic outcomes using Wiva Science inertial sensors by Letsense®. Data were collected preoperatively and 4 months after surgery. Results: All PROMs exhibited statistical significance in improvement from pre- to postoperative periods, except for one. Physical examinations showed no significant changes of the foot shape and alignment. Plantar pressure analyses revealed no significant changes in static and dynamic evaluations, but a more uniform distribution of plantar pressure was observed between the two periods. Inertial sensor parameters demonstrated no significant differences, except for a significant reduction in stride length and step length for the operated foot after surgery. Conclusions: Gait analysis using inertial sensors and plantar pressure measurements offer ease of handling, cost effectiveness, portability and swift data reading, making them highly appealing for widespread clinical use. Integrating these tools into the routine assessments of patients with TAA holds promise for advancing precision of treating this condition and our depth of its understanding, contributing to more comprehensive and insightful patient care.

“…3D printed orthotic foot insoles elevated the medial longitudinal geometry for therapeutic effects on flatfoot patients after shape customisation [ 5 ]. A recent publication on the customised total talar replacement kept abreast of the importance of joint motion, segment movements, and joint contact force during gait [ 6 ].…”

“…They showed that the TTR better reproduced the foot joint motions, segment movements, and plantar pressure map of an intact foot during walking and thus could be a prospective surgical alternative for pathological ankles from a biomechanical perspective. Nevertheless, TAA reduced ankle mobility and increased movement of the adjacent joints and forefoot plantar pressure [ 8 ].…”
