Gout rarely occurs in the setting of prior total joint replacement. It can present as an acute or chronic painful joint that may mimic prosthetic joint infection with further similarities found on physical examination and initial workup. Elevated leukocyte count, erythrocyte sedimentation rate, and C-reactive protein are common to both conditions. The confirmatory test to distinguish infection versus inflammatory arthropathy is joint aspiration with crystal or micro-organism identification microscopically. Establishing proper diagnosis is important in guiding appropriate treatment, which may prevent the unnecessary removal of implants. The current study includes a review of the literature and presents a case of bilateral gouty arthropathy after total knee arthroplasty.
Periprosthetic distal femur fractures can be treated nonoperatively, with open reduction and internal fixation or with more constrained prostheses. Distal femoral replacement is typically a last resort treatment option for comminuted periprosthetic or osteoporotic distal femoral fractures in patients with poor bone stock or resistant nonunions. We report the case of a 54-year-old female with a remote history of bone mulch ACL reconstruction who sustained an intraoperative comminuted bicondylar distal femur fracture during a primary total knee arthroplasty. This patient was treated with a distal femoral replacement and successfully returned to her preoperative function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
