“…While any joint can be affected, those that are most commonly reported are the distal extremities such as wrists, metacarpal and interphalangeal joints, as well as the ankles and metatarsophalangeal joints [18, 20, 36, 40, 41], though some studies have indicated that the knee is also commonly affected [9, 31, 36, 42]. While the majority of cases have this distribution, it is important to recognize that patient presentation can vary and include asymmetric polyarthritis, monoarthralgia, and involvement of less commonly affected joints, such as the elbow, hip, and shoulder, as well as vertebral pain in sacroiliac, lumbosacral, and cervical regions [9, 43, 44].…”
