膝關節再置換後導致脛神經病變：個案報告

Abstract

We describe a 74-year-old woman with right knee osteoarthritis experiencing right tibial neuropathy because of complications of total knee arthroplasty revision. Weakness in the right toe flexors and paresthesia over the sole of the right foot were observed after operation. A nerve conduction study and electromyographic examination indicated right tibial neuropathy. Radiography indicated a prosthesis fragment in the right popliteal fossa, and its location was different before and after surgery. Prosthesis fragment dislodgement was also confirmed through ultrasonography, and the nearby tibial nerve may have been entrapped because of the dislocation process and surrounding tissue fibrosis. Ultrasonography confirmed the prosthesis fragment did not contact the right tibial nerve directly. After considering her medical condition, we chose conservative treatment including therapeutic exercise, electrical stimulation and ultrasound-guided 5% glucose tibial nerve hydrodissection, and the patient's symptoms much recovered 6 months later. The causes of tibial neuropathy in our case may be different from those reported previously. Ultrasonography played a valuable role in the examination and treatment of the injured nerve.
