Feczko PZ, et al. – The accuracy of the oscillating tip saw system (Precision Saw = PS) was compared with that of conventional fully oscillating blade system (Sagittal Saw = SS) during computer–assisted total knee arthroplasty (CAS–TKA). Findings did not prove a superior overall accuracy of the Precision Saw over the Sagittal Saw. Except for one cutting plane that favoured the SS, significantly better accuracy was shown with the PS in the two cutting planes. Greater number of outliers were found using the PS.
