Background: With the increasing prevalence of obesity, there is growing awareness of the impact of overweight and obesity on total hip arthroplasty (THA). Research exploring the accuracy of acetabular component orientation in THA between robotic-assisted and manual techniques across different BMI categories is insufficient.
Methods: This prospective study evaluated 221 patients who underwent THA with a Robotic Interactive Orthopaedic Arm system and 252 patients who underwent manual THA between March 2022 and January 2024. The patients were divided into four groups according to their BMI. We analysed whether there were differences in the accuracy of acetabular component positioning between robotic-assisted THA and manual THA across different BMI categories.
Results: In the overweight group, robotic-assisted THA achieved a significantly higher rate of abductions within the target range (73/6) than manual THA (62/28) (p = 0.000). Both abductions and anteversions within the target range were also significantly more frequent in the robotic-assisted THA group (69/10) than in the manual THA group (56/34) (p = 0.000). Among the obese patients, robotic-assisted THA showed a perfect record for anteversions within the target range (29/0), markedly outperforming manual THA (39/6) (p = 0.040).
Conclusion: In the overweight (24 kg/m² ≤ BMI < 28 kg/m²) and obese (BMI ≥ 28 kg/m²) groups, robotic-assisted THA demonstrates significantly greater accuracy in acetabular component positioning compared to manual THA. This indicates that robotic-assisted technology may provide a more precise positioning of the acetabular component in overweight and obese patients.

Aims: Excellent outcomes have been reported following CT-based robotic arm-assisted total hip arthroplasty (rTHA) compared with manual THA; however, its superiority over CT-based navigation THA (nTHA) remains unclear. This study aimed to determine whether a CT-based robotic arm-assisted system helps surgeons perform accurate cup placement, minimizes leg length, and offsets discrepancies more than a CT-based navigation system.
Methods: We studied 60 hips from 54 patients who underwent rTHA between April 2021 and August 2023, and 45 hips from 44 patients who underwent nTHA between January 2020 and March 2021 with the same target cup orientation at the Department of Orthopedic Surgery at Ozu Memorial Hospital, Japan.

Background: Accurate component placement plays a critical role in the outcome of total hip arthroplasty (THA). Robotic-assisted THA (R-THA) has emerged as an option to optimize this aspect compared to the conventional manual THA (C-THA). The aim of this meta-analysis was to analyze the studies comparing R-THA and C-THA.

Introduction: Robot-assisted instrumentation during total hip arthroplasty (THA) has the potential to improve acetabular cup positioning. This study aimed to evaluate the precision of robotic-arm-assisted THA (rTHA) and assess whether the system can provide accurate cup positioning comparable to conventional THA (cTHA).
Methods: A single-center prospective cohort study consisting of 151 patients who underwent THA (108 rTHA and 43 cTHA).

Introduction: The use of technology in direct anterior approach (DAA) total hip arthroplasty (THA) is expanding. Although the use of computer-navigation (CN-THA) and robotics (RA-THA) has previously demonstrated improved component positioning, it is important to understand whether its use is associated with differences in intraoperative complications or early return to the operating room when compared to fluoroscopy-only (manual-THA) DAA THA.
Methods: 3433 DAA THAs (226 RA-THA, 1007 CN-THA, 2200 manual-THA) performed at a single institution were retrospectively reviewed.

Introduction: Direct anterior approach (DAA) for total hip arthroplasty (THA) is increasing in popularity. Fluoroscopy is commonly utilized during DAA THA to increase the accuracy of component placement. The objective of this study was to compare the mean fluoroscopy time and radiation dose for DAA THA when utilizing robotic-assistance (RA), computer-assisted navigation (CAN), or manual (M) technique.
