An early sign of intraarticular fracture of the lateral tibial plateau during opening wedge high tibial osteotomy

Abstract

Intraarticular fracture of the lateral tibial plateau is one of the serious complications in medial opening wedge high tibial osteotomy (HTO). We present a case of fracture of the lateral tibial plateau during medial opening wedge HTO. The authors have found the early fracture sign, uneven divergence gap of proximal and distal parts during enlargement of the osteotomy site with a dilatator, a useful marker for early detection and prevention of fracture extending.
