Adverse local tissue reactions (ALTRs) due to tribocorrosion of head-neck taper junctions in contemporary metal-on-polyethylene (MoP) total hip arthroplasty (THA) are emerging as an important reason for failure requiring revision surgery. This study aimed at: (1) reporting early complication rates and outcome, and (2) identifying risk factors associated with complications of revision surgery for head-neck taper corrosion in patients with MoP THA. ⋯ A high rate of early complications (25%) and re-revisions (10%) was observed after revision of ALTR associated with head-neck taper corrosion. Pre-revision MRI findings of solid lesion(s) with abductor deficiency and intraoperative tissue damage were risk factors associated with the occurrence of a complication after revision surgery. This information provides clinically useful information for clinical decision-making and preoperative counseling of MoP THA patients undergoing revision surgery for head-neck taper corrosion.

The proximal femur represents the most common site of metastatic bone disease in the appendicular skeleton, and associated pathologic pertrochanteric femur fractures contribute to cancer-related morbidity and mortality. Controversy exists as to whether these injuries are best managed with intramedullary nailing (IMN) or with arthroplasty. ⋯ Level III.

Acute kidney injury (AKI) can complicate primary total joint arthroplasty (TJA) of the hip and knee, although the incidence of AKI following revision TJA including prosthetic joint infection (PJI) is poorly defined. We assessed the incidence and risk factors for AKI following revision TJA including surgical treatment of PJI with placement of an antibiotic-loaded cement (ALC) spacer. ⋯ AKI develops following aseptic revision TJA at a rate similar to primary TJA, but at a significantly higher rate following surgery for PJI with or without placement of ALC.

The diagnosis of a periprosthetic joint infection (PJI) remains a clinical challenge, as there is no uniformly accepted gold standard. In 2011, the Musculoskeletal Infection Society (MSIS) convened a work group to create a standardized definition for a PJI that could be universally adopted. Based on the MSIS criteria, the diagnosis of a PJI can be made with 1 of the 2 major criteria, or 3 of the 5 minor criteria. The purpose of this study was to determine the likelihood of having a PJI based on the number of positive minor criteria and thereby develop a prediction algorithm for differentiating between a chronic PJI and a non-PJI based on the number of positive MSIS minor criteria. ⋯ III.
