Minimal incision total knee arthroplasty (MI TKA) was developed with the potential to decrease surgical trauma, pain, and recovery time. While this procedure has increased in popularity, some surgeons have questioned its safety and long-term efficacy. In this study 58 consecutive revision total knee arthroplasties (TKAs) (57 patients) performed at one academic medical center from 2006 to 2008 are reviewed. Prospectively collected clinical and radiographic data included: incision length, gender, age, time to revision surgery, and primary diagnosis at time of revision. Of these, 34 knees involving infection and rerevision were excluded. Of the remaining 24 knees, 11 knees that met inclusion criteria had undergone MI TKA. There were no differences between the groups with regard to age, diagnosis, body mass index, and gender. Average time to revision was shorter for the MI TKA patients (29 vs. 65 months, p < 0.032, odds ratio 14.7). Reasons for revision were aseptic loosening (55%), pain/stiffness (27%), malrotation (9%), and instability (9%) in the MI TKA group and aseptic loosening (53%), instability (15%), pain/stiffness (8%), malrotation (8%), combined malrotation and instability (8%), and polyethylene wear/osteolysis (8%) in the traditional TKA group. These data suggest that MI TKA may be a risk factor for early revision.
