Electrocautery Alters the Near‐Surface Microstructure, Phases, Composition, and Hardness of Ti‐6Al‐4V

Journal of Biomedical Materials Research Part A, Volume 114, Issue 1, January 2026.
ABSTRACT Despite the high success rates of total joint arthroplasty procedures, including total knee and hip replacements, implant failures still occur. This study investigated a potential, yet underrecognized, cause of implant failure: unintentional damage from the contact of electrosurgical blades with metal implant alloys.

In Vivo Corrosion of Acetabular Modular Tapers Reduces Local Corrosion Resistance: Near‐Field Electrochemical Impedance Spectroscopy as an Indicator of the Type and Severity of Corrosion in Retrieved Hip Implants

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT Retrieved hip implant components experience a range of corrosion types and severity, often on small surface areas of the taper region. Tribocorrosion‐related damage within modular taper regions and resulting changes of the oxide‐covered surface can alter the local impedance of the interface.

Clinico-demographical Profile of Pelvis and Acetabular Fracture Presenting in Tertiary Care Center of Nepal: An Observational Study

Journal of Nepal Medical Association
Introduction: Pelvis and acetabular fractures are complex, high-energy trauma and are often associated with life threatening injuries. The majority of them require surgical intervention and extensive rehabilitation. The epidemic figures are necessary to

Anterior knee pain and femoral torsion in female patients: Rationale and outcomes of rotational femoral osteotomy

Journal of Experimental Orthopaedics, Volume 13, Issue 1, January 2026.
Abstract Femoral and/or tibial torsional abnormalities are highly prevalent in female patients with anterior knee pain (AKP) who are recalcitrant to appropriate conservative treatment. In this paper, we focus on increased internal femoral torsion, which sometimes is an under‐recognised factor contributing to AKP. Two experts in patellofemoral pathology

Biomechanical comparison of a new minimally invasive technique versus conventional plating for the treatment of open book symphyseal injuries in osteoporotic human pelvises

Journal of Experimental Orthopaedics, Volume 13, Issue 1, January 2026.
Abstract Purpose Traumatic open book injuries of the pubic symphysis require stable fixation while minimizing surgical morbidity. Traditional symphyseal plating is associated with complications such as implant failure and infections. This study aims to evaluate the biomechanical performance of a novel minimally invasive technique using an internal ...

Liaw's Ellipse Anteversion Method for Distinguishing Acetabular Component Retroversion from Anteversion on Plain Radiographs

Orthopaedic Surgery
Improper acetabulum component position is a significant risk factor for postoperative dislocation after total hip arthroplasty. Several radiographic two‐dimensional methods exist for measuring acetabulum component anteversion, but they cannot distinguish

Correlation of the cross-over ratio of the cross-over sign on conventional pelvic radiographs with computed tomography retroversion measurements [PDF]

, 2018
Objective: To find a correlation between the cross-over ratio of the cross-over sign on conventional anteroposterior (AP) pelvic radiographs and retroversion measurements (‘roof-edge angle' and ‘equatorial-edge angle) on computed tomography (CT) scans ...

In Vitro Evaluation of Hemiarthroplasty Bearing Materials: A Scoping Review (Part I)

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Hemiarthroplasty is used to treat joint damage confined to one side, aiming to preserve the remaining healthy cartilage and bone while addressing conditions like femur fractures and osteonecrosis; however, challenges persist due to cartilage wear and inconsistent clinical outcomes.

Laser Disinfection Acts as Biofilm‐Disrupter in Periprosthetic Joint Infection (PJI)

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Infections after joint arthroplasties represent a devastating and progressively escalating complication with increased morbidity and mortality. The eradication of biofilms from infected implants is still an unsolved challenge. The erbium‐doped yttrium aluminum garnet (Er:YAG) laser, which delivers high‐energy light for rapid tissue ablation ...
