    Abstract Aim. To determine the most effective administration of tranexamic acid (TXA) in patients with primary total knee arthroplasty (TKA). Material and Method. We enrolled a total of 400 patients (154 men and 346 women) in this randomized trial (4 groups, each of 100 patients). The first group (IV1) had a single intravenous dose (15 mg TXA/kg) prior to skin incision. Group 2 (IV2) had TXA in 2 intravenous doses (15 mg TXA/kg): prior to skin incision and 6 hours after the first dose. Group 3 (TOP) had 2 g TXA in 50 mL of saline irrigated topically at the end of the surgery. The fourth group (COMB) combined IV1 and TOP regimens. We monitored the amount of total blood loss (TBL), haemoglobin drop, use of blood transfusions (BTs), and complications in each patient. Results. The amount of TBL was significantly lower in IV1, IV2 and COMB regimens compared to the TOP (P<0.0001). The lowest decrease in haemoglobin within 12 hours after surgery was observed in intravenous regimens (P=0.045). A significant difference in haemoglobin decrease on day 1 after the surgery was demonstrated in the COMB and intravenous regimens (P=0.011). Conclusion. In primary TKA, it is preferable to administer TXA intravenously in two doses or in a combined regimen. Simple topical administration of TXA was not as effective and is indicated only in cases where systemic administration of TXA is contraindicated. No substantial complications occurred in either group of patients.

    Abstract A projected increased use of total joint arthroplasties will naturally result in a related increase in the number of prosthetic joint infections (PJIs). Suppression of the local peri-implant immune response counters efforts to eradicate bacteria, allowing the formation of biofilms and compromising preventive measures taken in the operating room. For these reasons, the prevention of PJI should focus concurrently on the following targets: (i) identifying at-risk patients; (ii) reducing "bacterial load" perioperatively; (iii) creating an antibacterial/antibiofilm environment at the site of surgery; and (iv) stimulating the local immune response. Despite considerable recent progress made in experimental and clinical research, a large discrepancy persists between proposed and clinically implemented preventative strategies. The ultimate anti-infective strategy lies in an optimal combination of all preventative approaches into a single "clinical pack", applied rigorously in all settings involving prosthetic joint implantation. In addition, "anti-infective" implants might be a choice in patients who have an increased risk for PJI. However, further progress in the prevention of PJI is not imaginable without a close commitment to using quality improvement tools in combination with continual data mining, reflecting the efficacy of the preventative strategy in a particular clinical setting.

    Title translation Nutraceuticals in therapy of knee osteoarthritis: orthopaedic view.
    Abstract Knee osteoarthritis is one of the most frequent diagnoses of load-carrying joints encountered in orthopaedic surgeons offices. Depending on the clinical stage, the therapy starts with conservative treatment. Corrective osteotomy is indicated in younger patients without an extensive and serious impairment. Implantation of TKR (total knee replacement) is usually indicated in more advanced stages. One of the pillars of conservative therapy is analgesics and non-steroidal antirheumatic drugs. A specific group consists of perorally administered drugs for suppression of symptoms or even deceleration of knee osteoarthrosis. These products are popular mainly thanks to their good tolerance and minimal side effects. The clinical effect ranges between minimal and medium depending on the degree of osteoarthrosis, type of drug and study. Similar to rheumatologists, orthopaedic surgeons also find it difficult to identify candidates suitable for a particular type of therapy, except indication for TKR. By all means, nutraceuticals are still considered part of clinical practice.Key words: chondroitin sulphate - glucosamine sulphate - knee osteoarthrosis - methylsulfonylmethane - nutraceuticals - pharmaceutical intervention.

    Abstract Purpose of review: Joint replacement has revolutionized the treatment of end-stage arthritis. We highlight the key role of macrophages in the innate immune system in helping to ensure that the prosthesis-host interface remains biologically robust.
    Recent findings: Osteoimmunology is of great interest to researchers investigating the fundamental biological and material aspects of joint replacement. Constant communication between cells of the monocyte/macrophage/osteoclast lineage and the mesenchymal stem cell-osteoblast lineage determines whether a durable prosthesis-implant interface is obtained, or whether implant loosening occurs. Tissue and circulating monocytes/macrophages provide local surveillance of stimuli such as the presence of byproducts of wear and can quickly polarize to pro- and anti-inflammatory phenotypes to re-establish tissue homeostasis. When these mechanisms fail, periprosthetic osteolysis results in progressive bone loss and painful failure of mechanical fixation. Immune modulation of the periprosthetic microenvironment is a potential intervention to facilitate long-term durability of prosthetic interfaces.

    Abstract The use of biomaterials and implants for joint replacement, fracture fixation, spinal stabilization and other orthopedic indications has revolutionized patient care by reliably decreasing pain and improving function. These surgical procedures always invoke an acute inflammatory reaction initially, that in most cases, readily subsides. Occasionally, chronic inflammation around the implant develops and persists; this results in unremitting pain and compromises function. The etiology of chronic inflammation may be specific, such as with infection, or be unknown. The histological hallmarks of chronic inflammation include activated macrophages, fibroblasts, T cell subsets, and other cells of the innate immune system. The presence of cells of the adaptive immune system usually indicates allergic reactions to metallic haptens. A foreign body reaction is composed of activated macrophages, giant cells, fibroblasts, and other cells often distributed in a characteristic histological arrangement; this reaction is usually due to particulate debris and other byproducts from the biomaterials used in the implant. Both chronic inflammation and the foreign body response have adverse biological effects on the integration of the implant with the surrounding tissues. Strategies to mitigate chronic inflammation and the foreign body response will enhance the initial incorporation and longevity of the implant, and thereby, improve long-term pain relief and overall function for the patient. The seminal research performed in the laboratory of Dr. James Anderson and co-workers has provided an inspirational and driving force for our laboratory's work on the interactions and crosstalk among cells of the mesenchymal, immune, and vascular lineages, and orthopedic biomaterials. Dr. Anderson's delineation of the fundamental biologic processes and mechanisms underlying acute and chronic inflammation, the foreign body response, resolution, and eventual functional integration of implants in different organ systems has provided researchers with a strategic approach to the use of biomaterials to improve health in numerous clinical scenarios.
