This study reports on differences in the use of minimally invasive surgery for total hip arthroplasty related to the direction of cup insertion against the operating table, intraoperative hip range of motion, stability, and a choice of cup liners for both a mini-incision posterior approach (MPA) and a mini-incision anterior approach (MAA) using Stryker Navigation's CT-Hip system. The MPA group consisted of 39 consecutive patients and the MAA group consisted of 33 consecutive patients. Clinically, there was no significant difference in the average Japanese Orthopedic Association hip score or the Oxford hip score preoperatively and at 6 months and 2 years follow-up. The intraoperative joint stability measurements showed no large difference between the two groups when malpositioning of . the cup was eliminated.
