Metallosis and Metal-Induced Synovitis Following Total Knee Arthroplasty: Review of Radiographic and CT Findings.
نویسندگان
چکیده
Metallosis and metal-induced synovitis are well-recognized complications of metal-backed polyethylene joint prostheses and have been frequently described in the orthopedic surgery literature; however, relatively fewer articles discussing the radiologic aspects of this complication have been published. To illustrate the importance of radiologic findings in the diagnosis and management of these patients, we present a case of metallosis and metal-induced synovitis complicating two revisions of a total knee arthroplasty, caused by polyethylene liner wear and dissociation of the polyethylene liner from the metal-backed patellar prosthesis. Specific attention is given to reviewing signs that aid in diagnosis, such as the "bubble sign," "cloud sign," and "metal-line signs."

Intraoperative findings revealed extensive polyethylene wear with ...
متن کاملMetallosis Presenting as Knee Pain 26 years after Primary Total Knee Arthroplasty
INTRODUCTION Metallosis occurs when periprosthetic soft tissues, synovium, and/or bone is infiltrated by metallic debris secondary to metal-on-metal wear. This debris can cause a chronic inflammatory reaction leading to joint instability, pain, and swelling, and may cause osteolysis, implant looseningand ultimately implant failure. CASE REPORT An 81 year old female, with a history of primary ...
متن کاملMetallosis: CT findings in a total hip arthroplasty
We report a case of a 50-year-old man with extensive metallosis 20 years after right total hip arthroplasty. CT demonstrated osteolysis and radiodense debris surrounding the right hip joint. Although the radiographic appearance of metallosis has been well documented in the literature, the CT appearance of metallosis after total hip arthroplasty has been only sparsely described.
متن کاملDelamination of tantalum porous coating from a TKA due to regional dissemination of debris.
Metallic debris from metal-on-metal bearings is a recognized mode of failure that may lead to implant loosening and periprosthetic soft tissue reactions. The sequelae of metallosis have been most commonly reported with respect to total hip arthroplasty. The authors report a rare case of metallosis following a hybrid metal-on-polyethylene total knee arthroplasty that used a porous tantalum tibia...
متن کاملAcute Metallosis Following Total Knee Replacement – A Case Report
INTRODUCTION Metallosis involving the knee joint most often results from metal-on-metal contact late in the life of a failing implant following polyethylene wear. We report a case of acute metallosis following knee arthroplasty in a previously healthy 59-year old male. CASE REPORT In June 2011, the patient underwent left knee arthroplasty for severe osteoarthritis with necrosis and bone edema...
