A 54-year-old woman presented with varus ankle arthritis, which was corrected with total ankle arthroplasty (TAA). Immediately postoperatively, she was insensate throughout the plantar foot. After seven weeks, she underwent tarsal tunnel release, and the tibial nerve was found to be intact. Plantar sensation improved by one week after exploration with neurolysis and was completely intact at one year.
Loss of plantar sensation can occur following TAA for varus arthritic deformity. One potential cause is tibial nerve compression from tightening the laciniate ligament, resulting in acute tarsal tunnel syndrome. The condition can be remedied with early recognition and tarsal tunnel release. .
一位 54 岁女性因内翻踝关节炎接受了全踝关节置换术（TAA），术后即刻整个足底均失去感觉。7 周后进行了跗管松解术，发现胫神经完整。探查松解后 1 周，足底感觉改善，1 年后完全恢复。
内翻性关节炎畸形行 TAA 后可出现足底感觉丧失。一种潜在的原因是拉紧裂状韧带导致胫神经受压，从而引发急性跗管综合征。早期识别和跗管松解可纠正该病症。
