Navigated total knee arthroplasty: a radiological analysis of 42 randomised cases.

The purpose of this study was to evaluate the use of a navigation device in a cohort of 42 total knee arthroplasties (TKA). The patients were randomised into two groups. Total knee arthroplasties performed using the conventional technique formed the control group (21 knees); the experimental group included 21 knees performed with the aid of a computed navigation system.
