CT and arthroscopic findings of the case shown in Fig. 2. a CT findings before OWHTO. The subchondral collapse of the medial tibial plateau was observed. b Arthroscopic findings during OWHTO showing the subchondral collapse and the defect of the medial tibial plateau. c CT findings at 19 months after OWHTO (at plate removal). The necrotic lesion has decreased in size, and remodeling of the lesion was observed. d Arthroscopic findings at plate removal. The necrotic lesion of the medial tibial plateau was covered with fibrous cartilage-like tissue
