Musculoskeletal infections including periprosthetic joint infections, osteomyelitis, fracture-related infections, spinal infections, septic arthritis, and other orthopaedic device-related infections are the most feared complications in orthopaedics and trauma surgery. If not diagnosed and treated accurately, multiple revision surgeries accompanied by prolonged antimicrobial therapies and prolonged hospitalisation may be required. These can lead to an enormous physical and psychological burden for patients and an increased economic burden for healthcare systems.
However, diagnosing a periprosthetic joint infection or other musculoskeletal infections can be very challenging, especially when caused by low virulent organisms. Surgical and antimicrobial therapy can be delayed or even neglected.
Our cluster ‘Musculoskeletal Infections’ at the Department of Orthopaedics and Trauma Surgery covers various topics from prevention and diagnosis to treatment options for patients with infections of the musculoskeletal system to optimize patient management in clinical routine.
Our group concentrates on performance analyses of different novel diagnostic methods and biomarkers in serum, synovial fluid, and tissue to improve the diagnosis of infections which may ease decision-making for surgeons (e.g. synovial fluid marker, serum inflammatory marker, histopathology, genotypical identification of microorganisms, etc).
Another focus is on the evaluation, optimization, and development of treatment and revision strategies. Our outcome assessment aims to improve surgical care for patients with infections of the musculoskeletal system with a special focus on periprosthetic joint infections.
Our group collaborates with European Bone and Joint Infection Centres and participates in multicentre clinical trials. Due to the clinical need for multidisciplinary care, we enjoy collaborating with different medical disciplines (microbiology, infectious disease, pathology, other surgical disciplines, etc.). Therefore, our cluster offers space for colleagues working in related areas of research in different disciplines to collaborate, debate issues, and discuss mutual interests. Colleagues – at whatever stage in their careers – are encouraged to be involved.
