BACKGROUND Oligoarticular juvenile idiopathic arthritis (oligoJIA), the most common chronic inflammatory arthritis of childhood, usually involves the knees and ankles. Severe oligoJIA monoarthritis presenting in a joint other than knees and ankles, is rare. FINDINGS We report four children who presented with severe isolated arthritis of the hip, wrist or elbow and were diagnosed with oligoJIA...

Objective: We report a rare case of revision total knee arthroplasty (TKA) for monoarthritis of the knee due to rheumatoid arthritis (RA). The patient underwent revision surgery at 8 years and 7 months after left unicompartmental knee arthroplasty (UKA). Case: The patient was a 72-year-old woman. She subsequently presented to the previous hospital with left knee pain of spontaneous onset at 7 y...

Acute monoarthritis can be the initial manifestation of many joint disorders. The most common diagnoses in the primary care setting are osteoarthritis, gout, and trauma. It is important to understand the prevalence of specific etiologies and to use the appropriate diagnostic modalities. A delay in diagnosis and treatment, particularly in septic arthritis, can have catastrophic results including...

Arthritis is a recognized complication of untreated coeliac disease. Symptoms and signs usually respond to the institution of a gluten-free diet. We report a case of occult coeliac disease presenting as a monoarthritis. Severe and progressive erosive damage has occurred in his talo-navicular joint despite a response to the institution of a gluten-free diet.

A description of the protracted course of kingella monoarthritis is given as an illustration of the importance of accounting for the slow growth, low viable numbers, and fastidious culture requirements of microbes that may be encountered in synovial samples. The practice of carrying out synovial fluid cultures in the same way as blood cultures is recommended.

Measles, mumps, and rubella vaccine carries a risk of joint symptoms particularly in children under 5 years. A boy who presented with an inflamed knee after measles and mumps vaccination is reported; synovial fluid aspirated from the joint contained 4.3 x 10(9)/l leucocytes. It is thought that the mumps component is the aetiological cause of acute monoarthritis.

It is recognised that, although in some patients monarthritis is rheumatoid in nature and progresses to a typical polyarthritis, the prognosis in many is not at all clear. In this study we have examined the clinical, serological and radiological features of patients with monarthritis. have assessed the value of open biopsy, and have attempted to make a firm diagnosis when possible.
