Knee Osteoarthritis
_______________________________________________
Knee osteoarthritis (OA) is a common condition that afflicts many adults.1,2 Studies of the prevalence of symptomatic knee OA have found:3
- 4.9% of adults aged ≥ 26 years old may be affected
- 9.2% of adults aged ≥ 45 years old may be affected
- 12.1% of adults aged ≥ 60 years old may be affected
Knee OA may limit an individual’s ability to perform routine physical activities.2,3,4 The symptoms of knee OA may include: 5,6
- Persistent knee pain
- Limited morning stiffness (typically <30 minutes)
- Reduced function
Signs of knee osteoarthritis may include: 5
- Enlarged bones of the knee
- Restricted movement
- Grating sound or sensation in the knee
What Can I Do to Possibly Prevent This?
__________________________________________________________________
Risk factors an individual may have control over include obesity and prior knee trauma.7 Two-thirds of obese adults have a lifetime risk of acquiring knee OA.8 Maintaining a healthy weight and avoiding high-risk activities such as extreme sports may help prevent this condition.
Are There Ways to Manage This Other Than With Medication?
_____________________________________________________________________________________________
The American College of Rheumatology recommends exercise and physical therapy as nonpharmacological therapies for patients with OA. Nonpharmacological therapy is considered the cornerstone of OA management and includes:9,10
- Physical therapy (manual therapy with supervised exercise)
- An individualized exercise program (aerobic and resistance exercise)
- Weight loss (if overweight)
- Patient education
- Self-management programs (e.g., Arthritis Foundation Self-Management Program)
- Assistive devices such as a walker or cane for ambulation, as needed
- Appropriate footwear (including appropriate insoles)
- Patella taping
- Heat
Exercise and Physical Therapy
____________________________________________________
Consultation with a physical therapist to guide an individual with an exercise program is recommended.1 A course of formal physical therapy consisting of exercise and manual therapy may be beneficial for a person with knee OA.11,12 Those who attend formal physical therapy treatment tend to take less medication at one year than those performing only a home exercise program.11
