Wichita Fusion Nail for Patients With Failed Total Knee Arthroplasty and Active Infection

In the study reported here, we retrospectively evaluated short-term results of knee arthrodesis using the Wichita® fusion nail (WFN) in patients with active infection.
Clinical examinations, x-rays, time to union, knee pain after fusion, and ambulatory status were compared in 7 patients who received the WFN. Mean fusion rate was
86%, mean time to fusion was 9.8 months, and mean complication rate was 57%. Complication rates were high, but clinical outcomes were acceptable, supporting
use of WFN as a reasonable way to salvage failed total knee arthroplasty in patients with active infection.
