Purpose: Accurate cup placement is challenging in total hip arthroplasty (THA) for dysplastic hip osteoarthritis (DHOA) because of the complex morphology of the acetabulum. Studies have reported good accuracy for total hip arthroplasty (THA) using computed tomography-based navigation (CTN); however, in recent years, portable navigation (PN) has become more widely applied because of its low cost and ease of use. This study aimed to compare the accuracy of portable navigation with that of CT-based navigation.
Methods: A total of 114 patients underwent THA for DHOA via the standard posterior approach in the lateral decubitus position using the CTN (CTN-THA group) or PN (PN-THA group) system. After propensity score matching, 32 patients were included in each group. The accuracy of cup inclination, anteversion, cup placement position, and operative time were compared between the groups.
Results: There was no difference in accuracy error between the CTN-THA (inclination 2.8 ± 2.0° and anteversion 3.4 ± 2.1°) and PN-THA groups (inclination 2.5 ± 1.8° and anteversion 2.6 ± 2.2°). The CTN-THA group (inclination 2.2 ± 2.0° and anteversion 2.1 ± 1.6°) achieved better navigation error compared to the PN-THA group (inclination 2.6 ± 2.2° and anteversion 3.8 ± 3.3°). The error of cup placement position in the anteroposterior direction was significantly larger in the PN-THA group (4.27 ± 3.02 mm) than in the CTN-THA group (2.13 ± 2.17 mm). The operative time was significantly longer in the CTN-THA group (115 ± 41 min) than in the PN-THA group (87 ± 19 min).
Conclusions: CTN-THA exhibited better accuracy than PN-THA for both cup placement angles and positions. CTN-THA tended to increase the operative time compared to PN-THA.

This study aims to evaluate the effectiveness of total hip arthroplasty (THA) with subtrochanteric femoral osteotomy in patients with Crowe type IV DDH in terms of functional outcomes, complication rates, and implant stability. The study was prospective, conducted in the University Clinical Center of Kosovo and Otrila Hospital from 2016 to 2022 and included 22 patients with Crowe type IV hip dysplasia who underwent the THA with a subtrochanteric femoral osteotomy procedure. The treatment was performed using the posterior approach, and the placement of the dual mobility acetabular cup was based on the anatomic hip center using a Quattro non-cemented endoprothesis.

Objective: This study aimed to explore whether total hip arthroplasty (THA) aided by full-process robotics was effective in patients undergoing developmental dysplasia of the hip (DDH).
Methods: Totally 112 patients were enrolled and classified into robotic-assisted group (n = 56) and the conventional group (n = 56). In addition, retrospective analysis was used for comparing the difference in therapeutic efficacy.

Background: The present study aimed to examine the impact of prior experience of computed tomography-based navigated THA (CTN-THA) on the accuracy of cup placement in robotic arm-assisted total hip arthroplasty via direct anterior approach using the Mako system (Mako-THA).
Methods: We evaluated the first 60 hips that underwent Mako-THA performed by surgeons with and without CTN-THA experience and compared the absolute error of pre-operative and post-operative cup placement using a three-dimensional template between the two groups.
Results: The CTN-user group demonstrated significantly better results in radiographic inclination, y-(sagittal) axis placement, and z-(vertical) axis placement than the non-CTN-user group (CTN-user group: 1.

Background: Computer-assisted surgical navigation was designed to reduce the rates of acetabular component malpositioning, a common cause for revision following primary total hip arthroplasty (THA). We compared intraoperative measures such as radiation exposure, radiographic acetabular cup placement, and outcomes of patients who underwent a THA using computer-assisted surgical navigation with augmented reality (AR) compared to those who underwent traditional manual THA with fluoroscopic assistance (FA).
Methods: We retrospectively reviewed 115 hips who underwent primary direct anterior THAs using the intraoperative AR surgical navigation system between 3/30/2021 and 12/30/2022.
