Sonographic appearance of fibrous nodules in patellar clunk syndrome: a case report.

Patellar clunk syndrome is a rare complication causing pain after total knee arthroplasty. However, it is important to differentiate it from the other causes of patellofemoral pain. In this article, we apply ultrasonography for the first time to demonstrate the suprapatellar fibrous tissue causing this condition.

Successful limb salvage of pathological fracture of the distal tibia caused by cancer metastasis.

Pathological fractures of the distal tibia as a result of cancer metastases are rare. In particular, the management of intraarticular fractures of the distal tibia has not been established. In this article, we present a case of pathological intraarticular fracture with an extensive bone defect of the distal tibia that was successfully treated by limb salvage with a locked intramedullary nail and pirarubicin-impregnated methylmethacrylate.
