Osteolytic Psuedotumor After Cemented Total Knee Arthroplasty

Wear debris leading to local inflammatory reactive changes and osteolysis is a common complication after total knee arthroplasty (TKA). While massive osteolytic lesions may be com- monly encountered in the revision setting, the appearance and location of these lesions rarely mimic expansile bone lesions. We report a case of severe osteolysis in a cemented TKA design, which presented as a pseudotumor of the fibular head. The diagnostic work-up and pathologic analysis are included in this report of a pseudo- tumor secondary to wear debris osteolysis.
