The article describes a case in which a popliteal cyst was identified presenting as a mass on the anterior aspect of the
right tibia. This occurred as a result of polyethylene wear debris from previous total knee arthroplasty. Although alternative
diagnoses for an anterior tibial mass are more likely, a popliteal cyst must be considered, particularly if the patient has a
history of total knee arthroplasty.
