Knee arthrodesis using a custom modular intramedullary nail in failed, infected knee arthroplasties: A concise follow-up note of 31 cases at a median of 13 years post-arthrodesis.
Knee arthrodesis utilizes an arthrodesis nail as a salvage technique for infected total knee arthroplasty (TKA), especially when the extensor mechanism is damaged, or the skin is compromised. This implant helps to minimize or prevent leg length discrepancy, while allowing immediate weight bearing without requiring bone fusion. However, there is a risk of infection. Surgical revisions were required in 19% of patients at 50 months' follow-up in our team's initial 31-patient case series. Since there is little long-term outcome data, we reviewed this same group of patients after a mean of 13 years to determine: (1) the implant's long-term survival, (2) the functional outcomes, (3) the microbiological changes in revision cases. ⋯ IV; Retrospective cohort study.
