Purpose: To reassess the diagnostic approach to a patient with a monoarticular disease in light of the up-to-date medical literature and to examine the practical utility of traditional and newer imaging tools in the setting of monoarthritis.
Results: The monoarticular disease can represent a medical emergency on the one hand and be a diagnostic conundrum on the other. The management rules of patients with monoarthritis have been established long ago, but various pitfalls still lead physicians off the right diagnosis at times. Septic, pseudoseptic arthritis and hemarthrosis are the most common diagnoses made in patients with an acute presentation, and a decision not to perform a diagnostic arthrocentesis is the most prevalent cause of misdiagnosis in this setting. Many rheumatic and infectious diseases can present with more indolent monoarthritis; careful history and physical examination frequently provide clues to the straightforward diagnosis in some cases, but the extensive investigation is needed in others. Imaging methods become indispensable in individuals with the non-inflammatory monoarticular disease, with magnetic resonance imaging being the gold standard for diagnosing pigmented villonodular synovitis, lipoma arborescence, avascular necrosis, or neuropathic arthropathy.
Conclusions: A great variety of medical disorders can present as a monoarticular disease. The disease presentation dictates different diagnostic behavior, while knowing the available imaging methods' diagnostic potential should further shorten the diagnostic process.

Article Synopsis
- Reactive arthritis (ReA) is a condition caused by an external infection that leads to joint inflammation without detectable pathogens, indicating a possible ongoing interaction between the host and pathogen remnants.
- The main trigger for classical ReA is bacterial infections, often from urogenital or gastrointestinal sources, with common pathogens including Chlamydia species and enterobacteria.
- Diagnosis relies on clinical symptoms, evidence of prior infection, and ruling out other arthritis types, while treatment focuses on managing inflammation with NSAIDs and other immunomodulators; antibiotics do not typically help reduce the disease duration.

Calcium pyrophosphate disease (CPPD) is a commonly diagnosed crystal-induced disease that typically presents as acute monoarticular or oligoarticular arthritis. It is less commonly seen in the spine, and its clinical importance in this area is still relatively understudied. Isolated spinal CPPD is quite rare; a diagnosis of spinal CPPD is almost always accompanied by peripheral CPPD.

Division of Biostatistics, University of Minnesota, Minneapolis, MN, USA.
Article Synopsis
- rVSVΔG-ZEBOV-GP is a vaccine that helps protect people from the Ebola virus and is the first one to be officially approved for this purpose.
- This study wanted to see how well a booster shot given 18 months after the first vaccine dose helped keep the immune response strong for a longer time.
- Healthy adults who might be at risk of exposure to Ebola participated in the trial, and the results measured their antibody levels 36 months after the first vaccination to compare those who got the booster with those who did not.

Orthopaedics, Dr. D.Y Patil Medical College, Hospital and Research Centre, Dr. D.Y. Patil Vidyapeeth (Deemed to be University), Pune, IND.
Article Synopsis
- Synovial chondromatosis, or Reichel syndrome, is a rare condition affecting monoarticular joints, characterized by the growth of cartilage and the formation of small calcified loose bodies within the joint.
- The condition can lead to severe joint dysfunction if untreated, commonly impacting larger joints like the knee and hip, but sometimes affecting smaller joints like those in the fingers.
- A case study of a 60-year-old woman with pain and swelling in her finger led to surgical intervention, which successfully removed the calcified loose bodies, followed by rehabilitation to restore motion.
Crystal-induced arthritis in prosthetic joints: a systematic review of clinical features, diagnosis, management, and outcomes.
BMC Rheumatol

John A. Burns School of Medicine, University of Hawai'i, Honolulu, HI, USA.
Article Synopsis
- A systematic review examined cases of crystal-induced arthritis (such as gout and calcium pyrophosphate deposition disease) in prosthetic joints, focusing on clinical presentations, diagnoses, treatments, and outcomes.
- The analysis, which followed PRISMA guidelines, included literature searches from multiple databases and identified 44 relevant cases from 1984 to 2021, predominantly affecting patients with knee arthroplasty.
- Results revealed that this type of arthritis often appears suddenly as monoarticular arthritis, can be mistaken for infections, and typically responds well to anti-inflammatory treatments within a week.
