“…A total of 12 RCTs that included 1,139 patients were included in the final analysis (Figure 1 ). Seven of these studies 20 21 22 23 24 25 26 assessed the use of computer-navigated THA versus manual THA while the remaining five 27 28 29 30 31 assessed the use of robotic-assisted THA versus manual THA. The mean age (robotic: 59.5 versus computer navigation: 61.2 versus manual: 61.0, P = 0.90) and BMI (robotic: 25.7 versus computer navigation: 27.0 versus manual: 26.8 kg/m 2 , P = 0.83) did not differ between the three cohorts.…”

Introduction: Recent years have observed the increasing utilization of robotic-assisted and computer navigation techniques in total hip arthroplasty (THA), given the proposed benefits of enhanced consistency and precision in implant placement. The purpose of this study was to conduct a systematic review of randomized controlled trials (RCTs) to determine whether differences in surgical times, adverse events, and implant positioning existed between manual, robotic-assisted, and computer navigation THA. Methods: PubMed, OVID/MEDLINE, and Cochrane databases were queried for RCTs comparing robotic-assisted versus manual THA and computer navigation versus manual THA at a minimum 1-year followup. Frequentist model network meta-analyses with P-scores were conducted to compare revisions, complications, and surgical times among the three treatment groups. A random-effects meta-analysis between computer navigation and manual THAs was conducted to analyze cup positioning because no robotic-assisted THA studies reported this outcome. Results: Five RCTs compared robotic-assisted and manual THAs, while seven compared computer navigation and manual THAs. manual THA was associated with significantly reduced surgical time in comparison with computer navigation (mean difference: 23.3 minutes) and roboticassisted THAs (mean difference: 8.6 minutes; P , 0.001). No difference was observed in the incidence of all-cause complications (computer navigation: 1.7%, manual: 6.6%, and robotic-assisted: 16.2%) or revisions (computer navigation: 1.0%, manual: 1.7%, and roboticassisted 4.8%) among the three treatment groups based on the network meta-analysis.

“…Third, functional parameters, such as pelvic tilt, were not included in the measurement of the current study. However, the issue of pelvic tilt is still an open question as pelvic tilt differs during gait cycle 26 , from preoperatively to postoperatively 27 , and from sitting to standing 28 . The use of navigation has four general limitations.…”

Impingement is a major source of dislocation and aseptic loosening in total hip arthroplasty (THA). We compared impingement free range of motion (ROM) using a novel computer navigated femur first approach to conventional THA. In addition, impingement between genders was also explored. In a retrospective analysis of 121 THA patients, subject-specific post-operative ROM was simulated using post-operative 3D-CT data, and compared with the benchmark ROM, essential for activities of daily living. Three parameters were defined to express both implant-to-implant (ITI) and bone-to-bone (BTB) impingement - coverage percentage, third angle, and impingement severity. Although coverage percentage was similar between the navigated and conventional group for both ITI (p = 0.69) and BTB (p = 0.82) impingement, third angle was significantly reduced in the navigation group for both ITI (p = 0.02) and BTB (p = 0.05) impingement. Impingement severity for both ITI (p = 0.01) and BTB (p = 0.05) was significantly decreased in the navigation group compared to the conventional. Impingement severity in men was considerably higher compared to women for both ITI (p = 0.002) and BTB (p = 0.02). Navigation guided femur first THA is able to improve alignment of ROM axis, and consequently, to reduce impingement in THA. Men seem to be more prone to impingement than women.
