Robotic-assisted total hip replacement using direct anterior approach

The combination of robotic assistance with the DAA represents a convergence of accuracy-driven technology and minimally invasive surgical philosophy. Technology-assisted hip arthroplasty has gained increasing attention as a mean to improve surgical accuracy, reduce complications, and improve long-term outcomes. In parallel, the direct anterior approach (DAA) has emerged as a popular muscle-sparing technique associated with early recovery and reduced postoperative pain in many reports. Current evidence suggests that total hip replacement (THR) using robotic technology achieves better acetabular socket orientation, a higher proportion of implants placed within predefined safe zones, and reduced variability compared with conventional techniques. Additionally, improved postoperative limb length and the horizontal femoral offset has been consistently reported. Despite these radiographic advantages, functional and patient-reported outcomes remain largely comparable between robotic and conventional THR. The safety profile of robotic arm-assisted THR via DAA appears comparable to conventional approaches, with no consistent reduction in complication rates, although improved accuracy may reduce outlier-related failures. The learning curve remains a consideration, as both DAA and robotic systems are independently associated with increased technical demands and operative time during early adoption. From an economic perspective, the high capital cost and uncertain long-term benefits continue to limit widespread adoption, particularly in high-volume centers with established outcomes. In conclusion, robotic-assisted THR via the DAA offers enhanced surgical precision and improved early recovery but has yet to demonstrate clear superiority in many patient-reported and long-term outcomes. Well-conducted, prospective clinical studies are needed to establish the role of these newer arthroplasty techniques.
