title: Non-oncologic total femoral arthroplasty: retrospective review.
abstract: Total femoral arthroplasty (TFA) is an option to amputation in the setting of excessive bones loss during revision total hip and knee arthroplasty. Twenty non-oncologic TFAs with a minimum of 2years follow-up were retrospectively reviewed. The average clinical follow-up was 73±49months. The incidence of new infection was 25% (5/20), while the overall infection rate was 35% (7/20). The incidence of primary hip instability was 10% (2/20), while the overall instability rate was 25% (5/20). Six patients (30%) required revision. The average pre-operative HHS was 30.2±13.1. The average post-operative HHS was 65.3±16.9. TFA is a viable alternative to amputation in non-oncologic patients with massive femoral bone deficiency. However, TFA performed poorly in the setting of infection and instability.
