Psoriatic Arthritis from Wright's Era Until Today

This article reviews advances related to psoriatic arthritis (PsA). While the period since Wright's seminal papers is emphasized, his achievements are reviewed in light of knowledge of PsA in his day, as well as knowledge gained since the seminal work of Wright and Moll. Since other presentations focus on pathogenesis and treatment, this article emphasizes the clinical features and prognosis, as well as development of outcome measures.
