Replantation of above-knee amputation: a surviving but dysfunctional case needing secondary amputation.

Above-knee amputations are rare injuries that need emergent replantation or primary amputation. Although survival could be achieved in selective cases, postoperative function of the affected limb is usually unsatisfactory and a late amputation has to be performed for poor prognosis or severe complications. Experience of the surgical team may play an important role in primary decision making, which leads us to report one case of above-knee replantation with poor postoperative function and needing a late amputation. Scoring systems, expected results based on our case, and a brief review of literature concerning above-knee replantations are discussed.
