Secondary aims were to assess the effectiveness of this ACG in reducing oedema, improving patient reported outcomes, and determining the patients' degree of satisfaction with the handling of the wrap.

Very early migration of a calcar-guided short stem: a randomized study of early mobilization and the influence of a calcium phosphate coating with 60 patients.

This study analyzed the migration of a calcar-guided short stem to determine the course of very early migration, as well as evaluated the effect of an additional calcium phosphate (CP) coating on a titanium plasma spray (TPS) coating, which has not been analyzed previously. Sixty patients were enrolled in this study and were treated with the A2 calcar-guided short stem. The implant coating was randomized with either the TPS or an additional CP coating, and radiostereometric analysis was performed with the baseline measurement before initial weight-bearing, along with follow-up examinations at 1 week, 6 weeks, 3 months, and 6 months.

An observational study of an adjusted patient blood management protocol intended to lower rates of transfusion following total knee arthroplasty in patients with preoperative anemia.

Background: Patients with preoperative anemia have a higher risk of requiring blood transfusion after major orthopedic surgery due to increased blood loss and closer transfusion thresholds. Various patient blood management (PBM) policies aim to reduce transfusion rates. This observational study aimed to investigate blood loss and evaluate the effectiveness of an adjusted surgical PBM protocol in patients with anemic chronic disease (ACD) undergoing elective total knee arthroplasty (TKA).

Postoperative cage migration and subsidence following TLIF surgery is not associated with bony fusion.

Pseudarthrosis following transforaminal interbody fusion (TLIF) is not infrequent. Although cage migration and subsidence are commonly regarded as evidence of the absence of solid fusion, there is still no evidence of the influence of cage migration and subsidence on fusion. This study aimed to evaluate cage migration and subsidence using computed tomography (CT) DICOM data following lumbar interbody fusion.

Application of an adjusted patient blood management protocol in patients undergoing elective total hip arthroplasty: towards a zero-percent transfusion rate in renal patients-results from an observational cohort study.

Background: Renal patients are at high risk of blood transfusion following major orthopaedic surgery. A variety of patient blood management (PBM) policies have been proposed to reduce the rate of transfusions. The aim of this observational study was to assess the performance of an adjusted PBM protocol in patients with chronic kidney disease (CKD) undergoing elective total hip arthroplasty (THA).

The study investigated whether the use of carbon fiber-reinforced PEEK screw material (CF-PEEK) can reduce magnetic resonance imaging (MRI) artifact formation. Two consecutive groups of patients were treated for degenerative spinal disorders of the lumbar spine with dorsal transpedicular spinal fusion. The first group (n = 27) received titanium pedicle screws.

[Adjusted mechanical alignment: operative technique-Tips and tricks].

Introduction: Mechanical alignment (MA) is a standardized procedure that aims to achieve a neutrally aligned leg axis. An alignment of the prosthesis closer to the patient's anatomy can be an approach for better clinical outcomes. The surgical technique of adjusted mechanical alignment (aMA) presented here is a modified extension-gap-first technique that takes into account the natural ligamentous tension of the knee joint so that ligamentous releases can be avoided as far as possible.

Translation, cross-cultural adaptation, and validation of the Italian language Forgotten Joint Score-12 (FJS-12) as an outcome measure for total knee arthroplasty in an Italian population.

Background: With ever-increasing numbers of patients undergoing elective total knee arthroplasty (TKA) and as TKA is performed in increasingly younger patients, patient demands and expectations have also increased. With improved patient outcomes, new PROMs with heightened discriminatory power in well-performing patients are needed. The present study aimed to translate and validate the Italian version of the Forgotten Joint Score (FJS-12) as a tool for evaluating pre-operative through longitudinal post-operative outcomes in an Italian population.
