Abstract
Purpose: To introduce our surgical technique and report the clinical results of the knee arthrodesis with a Huck-step nail after a failed infected TKA
Materials and Methods: We retrospectively reviewed four patients who underwent knee arthrodesis with a Huck-stepnail after failed infected total knee arthroplasty. The average age of the patients at the time of the arthrodesis was 73 years (range: 70–79 years) and the mean number of previous surgical procedures was 3.2 (range:3–4 procedures). All patients had medical problems including diabetes mellitus and hypertension. We performed local bone graft in all cases. The duration of average follow-up was 20.2 months (range:12–36 months).
Results: Bone union was achieved within 1 year after arthrodesis radiologically. There was neither displacement of nail nor loosening. The average limb-length discrepancy was 3cm, measured clinically. All patients had a discrepancy that was corrected with a shoe-lift.
Conclusion: Arthrodesis with a Huckstep nail after failed infected total knee arthroplasty provides immediate axial and rotational stability and allows weight-bearing without use of external support.
