Osteaoarthritis: Prognosis...

The most common course of OA is an intermittent, progressive worsening of symptoms over time, although in some patients the disease stabilizes. Prognosis also varies depending on which joint is involved.

Factors associated with progression of OA:

• Knees: High body mass index, varus or valgus knee deformity.
• Hips: Night pain, presence of femoral osteophytes, and subchondral sclerosis in females.
• Hands: Older age.
