“…Imageless navigation system, a computer-assisted procedure, exploits three-dimensional sensors positioned during surgery to detect the anatomical features, limb axes and joint orientation, avoiding exposure to X-rays [ 15 ]. Imageless navigated THA is believed to be more accurate than other techniques, as the use of these sensors is believed to overcome parallax or operator pitfalls with fluoroscopy or change in pelvis position during the operation [ 16 , 17 ].…”

Background There has been a growing interest in imageless navigation for primary total hip arthroplasty (THA). Its superiority over standard THA is debated. This meta-analysis compared surgical duration, implant positioning, Harris Hip Score and rate of dislocation of imageless navigation versus conventional THA. Methods The present study was conducted according to the PRISMA 2020 guidelines. All the clinical trials comparing imageless navigation versus conventional for primary THA were accessed. In January 2022, the following databases were accessed: PubMed, Web of Science, Google Scholar and Embase. No time constraints were used for the search. The outcomes of interest were to compare cup inclination and anteversion, leg length discrepancy, surgical duration, Harris Hip Score and rate of dislocation of imageless navigation versus conventional THA. Results Twenty-one studies (2706 procedures) were retrieved. Fifty-two percent of patients were women. There was between-group comparability at baseline in terms of age, body mass index (BMI), visual analogue scale, Harris Hip Score and leg length discrepancy (P > 0.1). Compared with conventional THA, the navigated group demonstrated slightly lower leg length discrepancy (P = 0.02) but longer duration of the surgical procedure (P < 0.0001). Cup anteversion (P = 0.6) and inclination (P = 0.5), Harris Hip Score (P = 0.1) and rate of dislocation (P = 0.98) were similar between the two interventions. Conclusion Imageless navigation may represent a viable option for THA.

Introduction Computer tomography (CT) based navigation is considered by some authors as an advance in total hip arthroplasty (THA). A meta-analysis was conducted to compare CT based versus conventional THA in terms of surgical duration of the procedure, leg length difference, acetabular cup position, and rate of dislocation. Material and methods The present study was conducted according to the PRISMA 2020. In December 2022, the following databases were accessed: PubMed, Web of Science, Google Scholar, Embase with no time constrain. All the clinical studies comparing CT based navigation versus the conventional THA were accessed. Results Data from 1801 procedures were collected. The mean age of the patients was 61.6 ± 5.3 years, and the mean BMI was 26.9 ± 2.3 kg/m2. There was between studies comparability at baseline in terms of age, BMI, pain score, Harris hip score, leg length discrepancy (P > 0.1). The navigated group demonstrated lower leg length discrepancy (P = 0.02), and lower degrees of cup anteversion (P = 0.002). Similarity was found in cup inclination (P = 0.98), surgical duration (P = 0.3), and the rate of dislocation (P = 0.6). Conclusion CT guided THA may have the potential to increase the accuracy of acetabular positioning and reduce the leg length discrepancy. Current evidence is very limited and heterogeneous, and no recommendations can be inferred. Further investigations are required to definitely clarify the role of CT based THA in current practice.

“…In addition to PT, navigation systems can address the multifactorial reasons that can contribute to instability and dislocation, which may improve functional alignment. Clinical data suggest that navigation offers a superior means than conventional methods for achieving the goals of reduced leg length discrepancy ( P = .004) [ 62 ] and offset [ [66] , [67] , [68] , [69] , [70] ].…”
