The purpose of this study is to compare computer-assisted to manual implantation-techniques in total hip arthroplasty (THA) and to find out if the computer-assisted surgery is able to improve the clinical and functional results and reduce the dislocation rate in short-terms after THA. We performed a concise minimum 2-year follow-up of the patient cohort of a prospective randomized study published in 2014 and evaluated if the higher implantation accuracy in the navigated group can be seen as an important determinant of success in total hip arthroplasty. Although a significant difference was found in mean postoperative acetabular component anteversion and in the outliers regarding inclination and anteversion (p < 0.05) between the computer-assisted and the manual-placed group, we could not find significant differences regarding clinical outcome or revision rates at 2-years follow-up. The implantation accuracy in the navigated group can be regarded as an important determinant of success in THA, although no significant differences in clinical outcome could be detected at short-term follow-up. Therefore, further long-term follow-up of our patient group is needed.

Anesthesiology, Showa University School of Medicine, Tokyo, JPN.
Postoperative disorders of consciousness can arise from various factors, making diagnosis challenging. This report presents a case of a disorder of consciousness that occurred after awakening from general anesthesia, in which various examinations including computed tomography (CT) and magnetic resonance imaging (MRI) were conducted, but the cause could not be identified. A man in his 60s with a history of hypertension and cerebral hemorrhage underwent revision total hip arthroplasty under general anesthesia for a left periprosthetic hip fracture.

Background: A contemporary trend favours a restricted kinematic alignment (rKA) strategy, incorporating safe boundaries to restore a variable percentage of a patient's natural alignment.This study aims to compare preoperative and postoperative coronal plane knee alignment (CPAK) in patients undergoing bilateral TKA with SAIPH implants (MatOrtho, UK). The concept was to control the implant (same prosthesis both sides), patient (bilateral model) and assess what effect any surgical alteration in alignment had on patient's outcomes measured by patient-reported outcome measures (PROMS) and patient satisfaction.

Introduction: In this article, we report a unique case of head-stem dissociation in a metal-on-metal total hip replacement which utilized an Exeter stem. Although metallosis and pseudotumor formation are well recognized complications of metal-on-metal hip replacements, head-stem dissociations are rare with few being reported in literature. To the best of our knowledge, this case report is the first to report this occurrence in an Exeter stem.

Introduction: Total hip arthroplasty (THA) surgeries are rapidly increasing due to an aging population, leading to an increase in degenerative hip osteoarthritis. However, 1% of these patients go through prosthetic joint infection (PJI), which gives rise to implant failure with prolonged periods of patient incapacitation and higher mortality risk.
Case Report: In this article, we report an unusual case of a 62-year-old male who developed a PJI 7 months after a THA.

Introduction: Total hip arthroplasty (THA) is recognized as one of the most effective surgical procedures for the treatment of end-stage hip arthritis. However, the increasing number of primary THA cases has led to a corresponding rise in the frequency of revision surgeries, which are often more complex and challenging due to severe acetabular bone loss. In such cases, managing Paprosky type 3A and 3B defects requires precise implant design and advanced surgical techniques.
