| Popis: | Revision total knee arthroplasty (rTKA) is a challenging problem in the setting of soft tissue defects. The purpose of this study was to evaluate patients who underwent rTKA requiring flap coverage and determine patient factors that predisposed them to failure. Forty-three consecutive patients (mean follow-up, 46.5 months) who underwent rTKA requiring flap coverage were retrospectively reviewed between January 1, 2000 and December 31, 2010. Sixteen of 43 patients experienced failure requiring either flap revision (n = 2) or above the knee amputation (n = 14). Patients with heart failure (p = 0.008), cancer (p = 0.049), or infection with Klebsiella pneumoniae (p = 0.002) had greater rates of failure. Smoking (p = 0.287), diabetes (p = 0.631), and flap type (p = 0.634, p = 0.801) were not associated with increased failure. Mean survival was 46.4 months. Survival of patients with a history of cancer (34.3 months) was less (p = 0.033) than those without (49.2 months). Flap coverage in rTKA is a viable limb salvage option for patients with soft tissue defects; however, failure rates are much higher than in patients not requiring flap coverage. |
