Presentation depends on etiology. Typically, pain is poorly localized and severe. Night and rest pain are present and are escalated with activity. Range of motion (ROM) is preserved in early disease; however, motion causes pain. Crepitation and locking are noted following subchondral collapse. With arthritic changes, ROM decreases mechanically.
