We report our experience with knee arthrodesis using a customized intramedullary nail implanted in 14 patients.
Indications for knee arthrodesis were: recurrent prosthesis infection (n = 11), post-traumatic septic arthritis (n = 1), aseptic loosening of a hinge prosthesis (n = 1), and nonunion (n = 1). A two-stage procedure was used for the 12 patients with infected joints.
Mean follow-up was 19 months. Weight bearing began during the first week after arthrodesis in 13 patients. First intention bone healing was achieved in 13 patients. Mean time to healing was three months. All patients rapidly recovered full independence. Complications were: one misinsertion of the tibial stem, one nonunion which fused after repeated grafting, and two recurrent infections (controlled chronic fistulae) which required skin flaps for cover.
We have found that this customized nail is a useful method for achieving bone fusion in patients with difficult indications for arthrodesis, particularly recurrent prosthesis infection.
