BACKGROUND: Achieving precise three-dimensional reconstruction during foot and ankle corrective surgeries is challenging. Intraoperative plantar pressure measurement (IPPM) can help assess foot morphology and detect abnormal pressure distributions. We developed an IPPM system using a navigation to align the floor reaction force with the femoral head's center. This study evaluates its accuracy in anesthetized patients.
PATIENTS AND METHODS: Fifteen patients undergoing lower limb surgery were enrolled. Plantar pressure was measured intraoperatively in the supine position and compared with preoperative standing measurements. Similarity was evaluated using normalized cross-correlation (NCC) and peak pressure site agreement across 12 predefined foot regions.
RESULTS: The IPPM device replicated standing plantar pressure, with a mean NCC of 0.92 ± 0.1 and a peak pressure site agreement rate of 76.7 ± 37.2 %.
CONCLUSIONS: The newly developed intraoperative plantar pressure-measuring device accurately replicates standing plantar pressure in anesthetized patients, offering potential for improving intraoperative assessments and corrective procedures.
