The present study aims to elucidate the applications of Titania (TiO2) doped calcium borosilicate glass as a biocompatible material in regenerative orthopedic applications. In this context, we have examined the bioactivity of various concentrations of TiO2 doped glasses with the help of simulated body fluid (SBF). Cytocompatibility, cell proliferation, and protein expression studies revealed the potential candidature of TiO2 doped glasses on osteoblast cell lines (MG-63). We hypothesized that TiO2 doped calcium borosilicate glasses are most cytocompatible material for bone implants...

Zn and Zn-based alloys have been recognized as highly promising biodegradable materials for orthopedic implants and cardiovascular stents, due to their proved biocompatibility and, more importantly, lower corrosion rates compared to Mg alloys. However, pure Zn has poor mechanical properties. In this study, Ag is used as a promising alloying element to improve the mechanical properties of the Zn matrix as well as its biocompatibility and antibacterial properties. Accordingly, we design three ZnAg alloys with Ag content ranging from 2...

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder known to cause progressive joint destruction. Over time, untreated RA can lead to pain and increasing disability, making orthopedic intervention necessary. The treatment of RA revolves around a variety of medications that blunt the overall immune response. However, this may increase the risk of infection and impair wound healing. Given the nature of this disease, orthopedists frequently encounter patients with RA in the operative setting. To optimize surgical outcomes, orthopedists must carefully manage and pay special attention to the adverse side effects of the complicated medication regimens of these patients perioperatively...

REVIEW
Andrew N Fleischman, Matthew S Austin
Surgical site infection (SSI) is one of the most common complications after orthopaedic surgery, leading to significant morbidity and its associated costs. Surgical guidelines strongly recommend the use of systemic antibiotic prophylaxis to reduce the risk for developing SSI. Locally administered powdered antibiotics have the potential to provide remarkably high intra-wound concentrations without risk for systemic toxicity. However, a paucity of high quality evidence in the orthopaedic literature has prevented widespread adoption of this technique...

BACKGROUND: Periprosthetic joint infection (PJI) is a major clinical problem in orthopedic surgery. Capnocytophaga canimorsus (C. canimorsus) is an unusual and hardly detectable bacterium. A review of the literature indicates that C. canimorsus affects mainly immunocompromised patients. It has not been reported to cause periprosthetic joint infections in immunocompetent patients so far. This case report aims to raise awareness of C. canimorsus in orthopedic surgery with special regard to joint arthroplasty...

Novel anticoagulants (NAGs) have emerged as the preferred alternatives to vitamin K antagonists. In patients being considered for regional anesthesia, these drugs present a layer of complexity in the preprocedure evaluation. There are no established tests to monitor anticoagulant activity and our experience is short with these drugs. These authors believe it is important to review the relevant hematology, orthopedics, and anesthesiology literature to provide a valuable reference for the clinician who is met with these challenges...

Extra-cellular matrix (ECM) components are important and their stabilization is significant in maintaining normal healthy joint environment. In osteoarthritis (OA), ECM components are altered and indicate disease progression. The joint ECM is composed of proteoglycans (aggrecan, perlecan, inter α-trypsin inhibitor), glycoproteins (fibronectin, lubricin, COMP) and collagen types (most abundantly collagen type II) which represent structural and functional transformation during disease advancement. ECM investigation revealed significant biomarkers of OA that could be used as a diagnostic and therapeutic tool in different canine orthopedic diseases...
