Implant-related osteomyelitis is common in orthopedics. Absorbable antibiotic-loaded calcium sulfate (ACS) is an alternative to nonabsorbable antibiotic depot options for osteomyelitis and fracture-related infections. This study aims to evaluate intramedullary canal filling and coating characteristics of ACS around tibial nails using a tibia SAWBONES model. This research was done to better understand the potential utility of ACS in situations requiring fixation in the setting of local infection.

Our research explores natural antimicrobials to combat orthopedic-device-related infections, a challenging issue due to antibiotic resistance. We reviewed agents from bacteria, fungi, viruses, animals, plants and minerals, evaluating their effectiveness and synergy with traditional antibiotics. Our findings suggest these natural alternatives could revolutionize infection management in orthopedic patients, offering new hope for reducing antibiotic resistance and improving treatment outcomes.

When acute soft tissue defects are present after knee arthroplasty, the infection risk is high. A gastrocnemius flap is used for anterior defects, and it is not usually combined with debridement surgery unless infection is clear. We examined the benefit of combining coverage treatment with debridement surgery, DAIR, comparing the isolated traditional coverage treatment. The results suggested a higher healing rate in the combined treatment, so we recommended it.

This study validated three models for predicting infection after hip and knee replacement surgery. By analyzing data from 2684 patients in the Netherlands, Portugal, and Spain, we found that the models developed by Tan, Del Toro, and Bülow effectively identified high-risk patients. These models can be used to enhance preoperative counseling and to tailor infection prevention measures individually, potentially improving outcomes and reducing healthcare costs.

A 71-year-old patient underwent shoulder surgery but developed a mild fever, swelling, a burning sensation, and redness of the right shoulder on postoperative day 5. Postoperative septic arthritis was diagnosed, and tissue culture revealed M. catarrhalis. Infection caused by M. catarrhalis is rare after orthopedic surgery, and this is the first reported case of septic arthritis of the glenohumeral joint occurring after arthroscopic surgery. 

Our orthopaedic hospital attempts to culture tuberculosis (TB) bacteria from all bone and joint samples sent to the microbiology laboratory. We looked at 6162 TB cultures performed between 2017 and 2022. Bacteria that cause TB, or similar bacteria, were found in 1 in every 229 patients. Tests were more likely to be positive in people being investigated for cancer (sarcoma) and in samples from the spine, whereas they were much less likely to be positive in samples taken from replacement joints.

This work outlines the first case study of Candida glabrata bone and joint infection successfully treated with 3 weeks of caspofungin followed by 10 weeks of rezafungin, a new generation of antifungal treatment, using a weekly administration mode.
