Abstract:
Robot-assisted total knee arthroplasty can achieve accurate lower extremity alignment better than conventional total knee arthroplasty, but it requires additional femoral and tibial pinning procedures. Complications because of pin fixation have been reported, such as fractures and infections around the pin, but nerve injuries due to pin fixation are rare. Among 360 patients who underwent robot-assisted total knee arthroplasty at the author’s hospital, five cases of dropped hallux occurred. All patients were treated with conservative treatment. Two cases showed good recovery of the great toe dorsiflexion muscle power, but three cases did not show improvement in muscle strength. This paper presents a case report with a literature review and shows that branches of the peroneal nerve can be damaged due to the tibial bone pinning procedure during robot-assisted total knee arthroplasty.
