Abstract
Unicompartmental knee arthroplasty (UKA) has increased in popularity, yet utilization by surgeons varies based on training, experience, or comfort level with the procedure. The operation is growing in popularity, and many institutions are publishing 10-year survival rates above 90%; however, joint replacement registries are still showing relatively high rates of revision and failure compared to total knee arthroplasty (TKA). Among the modes of failure, the frequency of periprosthetic infection following UKA is relatively low and estimated to be between 0.1% and 1.0%. Patients typically present in a similar manner to TKA infections, and surgeons should follow a similar algorithm for appropriate workup and confirmation for infection. Once the diagnosis of UKA infection is confirmed, the best method of management remains unclear, given the limited data available. Options for management include debridement and implant retention (DAIR), one-stage exchange of UKA to TKA and two-stage exchange involving antibiotic spacer placement. The management of UKA PJI involves surgical intervention and involves collaboration with medical and infectious disease services.
