Results: The differences of three techniques were statistically significant among

EBL, duration of procedure and length of hospital stay. Conventional group

revealed greater EBL with P <0.001. In the secondary outcome, shorter

operative time was found in navigation-assisted group (P=0.001). Lastly, the

length of hospital was shorter in mini-open group (P <0.001). However, it

should be noted that there was no difference in three techniques according to

Macnab Criteria.

Conclusion: Statistically, the few parameters had no significant effect the

overall outcomes of three groups. Therefore, three surgical methods offer

similarly in term of an approach of satisfactory outcomes.
