A clinical study of 105 upper tibial osteotomies was undertaken to investigate the incidence, pathology and outcome of perioperative neurological deficit. Motor weakness and/or sensory deficit occurred in 21 patients (20%) and in half of these the deficit was permanent. For descriptive purposes the fibula was divided into four zones. The occurrence of a neurological deficit was clearly related to the level of the fibular osteotomy. An anatomical explanation is proposed for this complication,
