TAmiRNA and Orthopaedic Hospital Speising Publish Landmark Data on promiR® for Accurate Diagnosis of Periprosthetic Joint Infections
On November 19th, 2025, the study “Synovial Fluid MicroRNA Biomarkers Enable Accurate Diagnosis of Hip and Knee Periprosthetic Joint Infections” by Frank et al. was published in the Journal of Bone and Joint Surgery. This peer-reviewed publication marks an important milestone in TAmiRNA’s biomarker development program and presents promiR®, our novel microRNA-based diagnostic panel designed to improve the pre-operative assessment of periprosthetic joint infections (PJIs). Clinical Challenge PJIs remain one of the most serious and difficult complications following total joint replacement. Current diagnostic methods—including inflammatory markers, imaging, and cultures—often lack sensitivity and specificity, especially for low-grade or culture-negative infections. Even advanced approaches such as PCR or next-generation sequencing can suffer from contamination risks and ambiguous [...]
