ABSTRACT

PURPOSE:

To evaluate the radiological stability according to the number of modular augments after revision of infected total knee arthroplasty (TKA). MATERIALS AND

METHODS:

Between February 2006 and September 2013, 37 patients (39 knees) followed > or =2 years after revision of infected TKA using modular metal augments for bone defects were reviewed retrospectively. We divided the patients into 3 groups according to the number of augments into group A ( or = augments, 7 knees) and evaluated the width of radiolucent zones around the implant at the last follow-up.

RESULTS:

There were 3 Anderson Orthopedic Research Institute type I, 33 type II, and 3 type III bone defects. The mean number of radiolucent zones of group A was 3 and the sum of width averaged 4.4 mm. In group B, the values were 4.8 and 6.2 mm, respectively. In group C, the values were 8.1 and 12.9 mm, respectively. The differences between the three groups were statistically significant.

CONCLUSIONS:

In revision TKA with modular metal augmentation caused by infected TKA, increased modularity can result in radiological instability.
