A, B Aseptic loosening of tibial component was observed on the left knee anteroposterior and lateral radiographs 10 years after primary TKA in a 77-year old woman. C, D One-stage revision TKA using a hybrid cementation technique with press-fit cementless stem was performed. Since anatomical malalignment in which the center of the tibial canal was eccentric was observed, a press-fit long stem of tibia (14 × 110 mm) with a 6 mm offset adapter was used
