Serum biomarkers in the diagnosis of periprosthetic joint infection: consolidated evidence and recent developments.

Eur Rev Med Pharmacol Sci 2019 Apr;23(2 Suppl):43-50

Department of Basic Medical Sciences, Neuroscience and Sense Organs. Orthopaedic & Trauma Unit, School of Medicine, University of Bari "Aldo Moro", AOU Consorziale "Policlinico", Bari, Italy.

Periprosthetic Joint Infection (PJI) represents one of the leading causes of revision prosthetic surgery, accounting for 25% of failed Total Knee Replacement (TKR) and 15% of failed Total Hip Replacement (THR). The search for a biomarker that, together with clinical and radiological findings, could improve the management of such a kind of patients is currently a big challenge for orthopaedic surgeons. This review aims (1) to assess the accuracy and the limitations of the traditional (Serum Erythrocytes Sedimentation Rate, C-reactive Protein, Procalcitonin, Interleukin 6, Tumor Necrosis Factor alpha), (2) and to analyse the emerging serum biomarkers (Presepsin, Toll-like Receptor 2, soluble urokinase-type Plasminogen Activator Receptor, Chemokine Ligand 2 and Osteopontin) in the diagnosis of PJI.

Step Length Asymmetry and its Associations with Mechanical Energy Exchange, Function, and Fatigue after Total Hip Replacement.

J Orthop Res 2019 Apr 12. Epub 2019 Apr 12.

Department of Kinesiology and Nutrition, , University of Illinois at Chicago.

Abnormalities in gait remain after total hip replacement (THR). The purpose of this study was to evaluate step length asymmetry and its links to other aspects of gait and physical function after THR and to investigate links with mechanical energy exchange. The rationale is that step length asymmetry may influence gait efficiency, which could adversely influence fatigue and physical function. Read More

The in vitro behaviour of canine osteoblasts derived from different bone types.

BMC Vet Res 2019 Apr 11;15(1):114. Epub 2019 Apr 11.

Comparative Biomedical Sciences, Skeletal Biology Group, The Royal Veterinary College, Royal College Street, London, NW1 0TU, UK.

Background: Our understanding of the biology of osteoblasts is important as they underpin bone remodelling, fracture healing and processes such as osseointegration. Osteoblasts isolated from human humeral samples display distinctive biological activity in vitro, which relates to the samples' bone types (subchondral (S), trabecular (T), cortical (C)). Our aim was to isolate primary osteoblast cultures from different bone types from the proximal femur of a clinical population of dogs presented for total hip replacement and compare the behaviour of the osteoblasts derived from different bone types, to identify a preferred bone type for isolation.

Subject-Specific Surgical Planning for Hip Replacement: A Novel 2D Graphical Representation of 3D Hip Motion and Prosthetic Impingement Information.

Ann Biomed Eng 2019 Apr 10. Epub 2019 Apr 10.

WMG, University of Warwick, Coventry, CV4 7AL, UK.

Prosthetic impingement (PI) following total hip arthroplasty (THA), which arises due to the undesirable relative motion of the implants, results in adverse outcomes. Predicting PI through 3D graphical representation is difficult to comprehend when all activities are combined for different implant positions. Therefore, the aim of the paper was to translate this 3D information into a 2D graphical representation for improved understanding of the patient's hip motion. Read More

Down-regulation of exosomal microRNA-224-3p derived from bone marrow-derived mesenchymal stem cells potentiates angiogenesis in traumatic osteonecrosis of the femoral head.

FASEB J 2019 Apr 9:fj201801618RRR. Epub 2019 Apr 9.

Department of Orthopaedics, Wuhan Third Hospital-Tongren Hospital of Wuhan University, Wuhan, China.

Traumatic osteonecrosis of the femoral head (ONFH) is a condition leading to the collapse of the femoral head, and the primary treatment is a total hip replacement, which has a poor prognosis. The current study was conducted with the aim of investigating the role of exosomes from bone marrow-derived mesenchymal stem cells (BM-MSCs) carrying microRNA-224-3p (miR-224-3p) in traumatic ONFH. Initially, a microarray analysis was performed to screen the differentially expressed genes and miRs associated with traumatic ONFH. Read More

Computed tomography evaluation of the periacetabular gap of a porous tantalum acetabular component.

Nagoya J Med Sci 2019 Feb;81(1):159-163

Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine, Nagoya, Japan.

The periacetabular gap is an inherent consequence of the peripheral rim press-fit of the porous tantalum acetabular component. The circumference of the prosthesis is clearly depicted with computed tomography (CT) images that have been optimised to reduce metal artefacts. This case report highlights the utility of single-energy metal artefact reduction (SEMAR) for CT evaluation of the periacetabular gap by comparing CT images with and without SEMAR. Read More

Acute kidney injury after hip or knee replacement: Can we lower the risk?

Cleve Clin J Med 2019 Apr;86(4):263-276

Assistant Professor, Department of Medicine, Division of Nephrology, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, PA, USA.

Patients who undergo hip or knee replacement (total joint arthroplasty) face a risk of acute kidney injury that may be higher than previously thought and that increases steeply if they undergo surgical revision to treat prosthetic joint infection. This article assesses the incidence of and risk factors for acute kidney injury after primary total joint arthroplasty or placement of an antibiotic-loaded cement spacer to treat infection, and offers suggestions on how to reduce the risk.

Causes of Revision in Young Patients Undergoing Total Hip Arthroplasty.

J Arthroplasty 2019 Mar 12. Epub 2019 Mar 12.

Adult Reconstruction and Joint Replacement Service, Hospital for Special Surgery, New York, NY.

Background: The purpose of this study was to identify reasons for revision of total hip arthroplasty (THA) in patients who underwent primary THA at or before the age of 35 years. We hypothesized that the reasons for revision in younger patients would be different from the general older population of patients undergoing THA because of the differences in diagnoses, complexity of deformities, and differences in activity level.

Methods: Data for 108 hips in 82 patients who underwent primary THA at our institution before the age of 35 years from 1982-2007 and subsequently underwent revision THA were reviewed. Read More
