With increasing patient awareness about various techniques of TKA and specific
demands for particular procedure, surgeons today face the challenge of being versed
with all the techniques of TKA. The purpose of this study is to compare the clinical
and radiologic outcome with three different techniques of TKA. One hundred fifty
consecutive TKAs were randomly divided into three groups and operated by a single
surgeon using conventional method, MIS technique and navigation assisted surgery.
Results were evaluated according to KSKS. Mean mechanical axis was significantly
different between three groups (p=0.014) and navigation-assisted surgery providing
more accurate alignment as compared to MIS (p value=0.014). Conclusion:
Navigation assisted surgery gives best prosthesis alignment. Alignment is less
predictable with MIS technique, so extra caution should be exercised while
attempting MIS.
