Gout, pseudogout, degenerative joint diseases and reactive arthritis are the most common causes of the atraumatic knee effusions. Rheumatoid arthritis very rarely presents as arthritis of one or two large joints. Arthrocentesis, plain radiography and screening blood tests should be performed to help narrow the differential diagnosis. In some cases, advanced imaging modalities such as MRI may be indicated. This study reports a case of rheumatoid arthritis in a 75-year-old gentleman with oligoarthropathy of two large joints as the presenting symptoms.<\/jats:p>","DOI":"10.1071\/hc20035","type":"journal-article","created":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T23:46:25Z","timestamp":1600213585000},"page":"391-394","source":"Crossref","is-referenced-by-count":1,"title":["Unilateral knee effusion in an elderly patient: an unusual presentation of rheumatoid arthritis"],"prefix":"10.1071","volume":"12","author":[{"given":"Morteza","family":"Khodaee","sequence":"first","affiliation":[{"name":"AUniversity of Colorado School of Medicine, Department of Family Medicine & Orthopedics, Division of Sports Medicine, AF Williams Clinic, Denver, Colorado, USA"},{"name":"CCorresponding author.
