This is a 50 year old female (Table 1, Patient 3) who presented with severe medial compartment osteoarthritis bilaterally (A). (B) She underwent cemented bilateral TKA, and this is an anteroposterior (AP) film one year post-operatively from her right TKA and two years post-operatively from her left TKA. The tibial component on the right side is malaligned with respect to the tibial canal (arrow). (C) This is an AP film six years post-operatively from her right TKA. She was not experiencing any pain, but there is clear evidence of tibial component loosening (arrow) and migration. (D) This is an AP film after revision right TKA.
