Results Significant differences were found in the femoral offset and overall complication rate between the conventional and navigation groups .
Additionally , the conventional group had significantly less anteversion than the navigation group .
However , the navigation group had significantly better inclination .
The operation time was significantly shorter in the conventional than navigation group .
Conclusion Both the OrthoPilot navigation system and conventional total hip arthroplasty result in significant improvements in patient function with similar overall complication rates and have their own advantages in achieving good cup position .
The conventional procedure has a shorter operation time than does use of a navigation system
Objective This study was performed to compare the clinical efficacy between the OrthoPilot navigation system and conventional manual surgery in patients undergoing total hip arthroplasty .
Efficacy and Safety of 3 Different Anesthesia Techniques Used in Total Hip Arthroplasty
Background This study compared the efficacy and safety of 3 different anesthesia techniques used in  total hip arthroplasty ( THA ) . Material / Methods We allocated 198 patients preparing to undertake THA into 3 groups : general anesthesia group ( GA group , n=66 ) , caudal epidural anesthesia group ( CEA group , n=66 ) , and spinal-epidural anesthesia group ( SEA group  , n=66 ) . We compared postoperative adverse effects occurring in patients of the 3 anesthesia groups . The Visual Analog Scale ( VAS ) score , Minimum Mental State Examination ( MMSE ) score , and β-amyloid ( Aβ ) expression were calculated to determine the effects of different anesthesia on the postoperative pain and cognitive dysfunction of patients . Results The CEA and SEA groups had lower rates of perioperative adverse effects than in the GA group . Patients in the GA group required significantly higher administration of analgesics after the surgery than those in CEA and SEA groups . Higher Aβ expression levels and VAS scores , as well as lower MMSE scores , were also seen in the GA group compared with the other 2 groups . Conclusions CEA and SEA were more effective than GA in THA , and CEA seemed to be a better anesthesia technique than SEA
