Imaging of the right knee and tibia/fibula demonstrates a total knee arthroplasty in place. There is a lucency beneath the medial tibial component suggesting possible hardware loosening or infection. Periosteal reaction along the lateral proximal tibial metadiaphysis and posterior tibial metaphysis is noted, which may represent infection. Patellar fragmentation, degeneration, and postsurgical changes appear unchanged. Further evaluation with bone scan or MRI is recommended.
