Article Synopsis
- The study evaluates the effectiveness of the iASSIST accelerometer-based navigation system in improving alignment accuracy during total knee arthroplasty (TKA) compared to conventional surgical methods using 3D imaging.
- A total of 83 knees were analyzed, with 42 using the iASSIST system and 41 using traditional guides, and results showed better alignment within 3° of neutral in both coronal and sagittal planes for the iA group.
- The findings concluded that iASSIST significantly improves femoral alignment during TKA, although there were no notable differences in clinical outcomes or patient reports at the 6-month check-up.
Purposes: Several studies have reported no differences in outcomes between total hip arthroplasty (THA) of osteotomized hips and primary hip THA. However, our results were worse after THA for converted osteotomized hips. Therefore, this study's aim was to clarify the differences between THA after osteotomy and primary THA for osteoarthritis in developmental dysplasia of the hip (DDH).

The purpose of this study was to investigate the morphology of the femur in patients who underwent THA, and to analyze the influence of femoral bowing on ROM due to implant impingement after THA.
Methods: The ROM was calculated from 100 hips in 90 patients who underwent THA using computed tomography data with a 3D dynamic analysis software.
