Q
Osteoarthritis (OA)
-Patho
A
- Changes in cartilage cellular matrix — earliest manifestations of OA are superficial erosions of the cartilage
—Loss of articular cartilage
—Thickening of sub-chondral bone
—Development of osteophytes

4
Q
Osteoarthritis (OA)
-Clinical Presentation
A
- Joint pain — deep aching pain aggravated by motion & weight bearing — Worse at night s/p vigorous activity
- Joint Stiffness — esp after inactivity — morning stiffness usually <30 minutes
- Joint Enlargement — Osteophyte formation
- Crepitus on movement w/ joint
- Later stages — Pain on motion and at rest; limitation of motion; mal-alignment; body protuberances from spurs
NO SYSTEMIC SYMPTOMS

7
Q
Osteoarthritis (OA)
-Management
A
- Control Pain
- Maximize functional independence — encourage movement
- Minimize disability
- Preserve quality of life
- Non-Pharm
- Weight loss, proper body mechanics
- Warm, moist heat or Ice
- PT — Good for quad development for knee pain - Pharm
- Acetaminophen & NSAIDS
- Capsaicin cream (Topical)
