Septic arthritis due to (LM) is extremely rare and most infections due to this organism are seen in immunocompromised patients. We describe a patient without immunological compromise, with a late total knee arthroplasty infection caused by LM treated with one-stage revision surgery. She had an elevated erythrocyte sedimentation rate (79 mm/h) and C-reactive protein (13 mg/dL). Aspiration of the knee joint yielded purulent fluid; cultures showed LM. The patient was given 6 weeks of intravenous ampicillin, followed by trimethoprim/sulfamethoxazole, and finally amoxicillin orally for 7 months. Two years after revision surgery, radiographs showed no evidence of implant loosening. This is a single case and although one-stage approach seemed to have worked, it should not be recommended on the basis of a single report.

Revision total knee arthroplasty (rTKA) is an increasingly common challenge for arthroplasty surgeons. The survivorship of rTKA is significantly lower than that of primary total knee arthroplasty, resulting in increasing numbers of repeat rTKA. These repeat rTKAs present unique challenges including potentially massive bone loss and increased risk of infection.

The survivorship of rTKA is significantly lower than that of primary total knee arthroplasty, resulting in an increasing incidence of repeat rTKA. These cases present multifactorial challenges including the skin and soft-tissue envelopes, bone loss, ligamentous compromise, and often a history of periprosthetic joint infection.

For these patients, endoprostheses have become the principal means to reconstruct the extremity following an oncologic resection because they offer an off-the-shelf-option that is modular, cost effective, and durable. As with other forms of arthroplasty, several modes of failure can occur, with infection being common.

It is important to provide an overview of the current management of periprosthetic fractures, including techniques for osteosynthesis and revision total hip and knee arthroplasty, as well as special considerations for periprosthetic acetabular fractures, periprosthetic tibial fractures, and interprosthetic femur fractures. In addition, the guiding principles for the management of potential subsequent complications including infection, nonunion, and instability are discussed.

Current treatment options have specific advantages and disadvantages. These treatments include hemiarthroplasty with or without glenoid reaming, total shoulder arthroplasty (TSA) with or without eccentric reaming, TSA with bone graft or posteriorly augmented glenoid implant, and reverse TSA.
