Arthrodesis of the knee with a vascularized fibular rotatory graft

We retrospectively reviewed the records of thirteen patients who had been
managed with an arthrodesis of the knee with use of a vascularized graft
from the ipsilateral fibula and fixation with an intramedullary rod. The
indications for the operation included a large skeletal defect secondary to
the resection of a tumor about the knee in eight patients, an infection at
the site of an arthroplasty in four (with failure of a previous
conventional arthrodesis in three of the four), and severe rheumatoid
gonarthrosis as well as a persistent non-union of the distal part of the
femur in one. The average age of the patients at the time of the operation
was forty-three years (range, twenty-six to seventy-six years). Most of the
patients had had multiple previous procedures (thirty-three operations had
been performed in ten patients). Twelve of the thirteen patients had a
solid fusion and a successful result after an average duration of follow-up
of fifty-one months (range, eight to ninety-three months). The remaining
patient, who had had four previous arthroplasties, had a recurrence of an
infection seven months after the operation and was managed with an
amputation. Six complications--including two superficial wound infections,
one deep wound infection, one deep venous thrombosis, one transient
peroneal-nerve palsy, and one delayed union--occurred in three patients.
