MRI of Total Hip Arthroplasty: Successful Ripple Artifact Reduction Using Wavelet Domain Filtering

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Slice encoding for metal artifact correction (SEMAC) is used in MRI for total hip arthroplasties for metal artifact reduction. However, ripple artifacts often arise near the implant, impairing diagnosis in affected regions. Hypothesis Applying a wavelet domain filter (WD‐Filter) might reduce ripple artifacts and improve image ...

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...

Step‐by‐step insight into gait analysis: A narrative review unlocking knee biomechanics

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Gait analysis offers a powerful tool for clinical and orthopaedic decision‐making. By quantifying spatiotemporal, kinematic and kinetic parameters during walking, it provides a dynamic window into joint function that static imaging cannot capture.

Revision Total Hip Arthroplasty Complicated by Metastatic Malignant Gastrointestinal Stromal Tumour

Journal of Orthopaedics, Trauma and Rehabilitation, 2014
Periprosthetic malignancy causing failure of total hip arthroplasty is a rare entity. Metastasis of malignant tumour to the proximity of orthopaedic implants is even more uncommon.

Dynamic coronal plane knee alignment: Femoral anatomy determines kinematic curve morphology, tibial anatomy determines curve position

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose A single hip–knee–ankle angle (HKA) angle does not reflect the biomechanics of native, arthritic or prosthetic knees. Since HKA varies throughout flexion, dynamic coronal alignment is best represented by a kinematic curve plotting HKA against the range of motion.

Prior osteosynthesis—unlike osteotomy—raises revision risk after total knee arthroplasty, predominantly via periprosthetic infection

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Previous knee surgery is discussed as a risk factor for total knee arthroplasty (TKA), yet most reports do not distinguish between osteotomy and osteosynthesis. The German Operationen‐ und Prozedurenschlüssel (OPS)‐based classification was used to compare the impact of these procedures on implant survival, mortality and complications ...

Patients with previous anterior cruciate ligament reconstruction achieve equally good outcomes after total knee arthroplasty: A Swedish registry‐based study of 7755 patients

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patients who have undergone anterior cruciate ligament reconstruction (ACLR) may later require total knee arthroplasty (TKA) due to osteoarthritis (OA). The impact of previous ACLR on patient‐reported outcomes (PROs) after TKA remains uncertain.

Synovial interleukin‐6 point‐of‐care testing, alone and combined with D‐dimer, supports rapid diagnosis of periprosthetic joint infection

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Data on the reliability of point‐of‐care (POC) tests for the rapid diagnosis of periprosthetic joint infections (PJI) using synovial fluid (SF) D‐dimer (DD), interleukin 6 (IL‐6) and procalcitonin (PCT) are limited. This study aimed to address this issue by evaluating the diagnostic accuracy of POC tests for SF DD, IL‐6 and PCT in ...

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Single‐stage revision for chronic fistulized infected total knee arthroplasty achieves infection‐free survival comparable to non‐fistulized cases

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The presence of a sinus tract in chronic periprosthetic joint infection (PJI) has traditionally been considered a contraindication to single‐stage total knee arthroplasty (TKA) revision. However, an increasing number of surgeons are now performing single‐stage revisions in this context, despite limited comparative data.
