Understanding Osteoarthritis |
Osteoarthritis (OA) is the most common type of arthritis, effecting over 32.5 million adults in the U.S. It's a degenerative joint disease that can impact various parts of a joint, including bone, cartilage, and ligaments. Although it has long been associated with aging, OA can affect adults of any age, especially those with previous joint injuries.
OA can lead to cartilage breakdown, changes in bone shape, and joint inflammation, causing pain, stiffness, and reduced mobility. Commonly affected joints include the hands, knees, hips, lower back, and neck. Though OA is more common in people over 50, younger adults may develop it after joint injuries.
While there is no cure for OA, many treatments can help manage symptoms, allowing individuals to stay active and maintain a good quality of life.

| Causes of Osteoarthritis |
| Several factors increase the risk of developing OA: |
|
| |
| Age: |
Risk increases with age, especially over 50. |
| |
| Joint injuries: |
Previous injuries, such as torn ligaments or fractures, can accelerate OA development. |
| |
| Overuse: |
Repeated joint use in sports or work can contribute. |
| |
| Obesity: |
Excess weight stresses joints and increases inflammation. |
| |
| Weak Muscles: |
Weakness around joints can lead to poor support, worsening OA. |
| |
| Genetics: |
OA tends to run in families. |
| |
| Gender: |
Women are more likely to develop OA than men. |
| |
| Environmental Factors: |
Lifestyle choices such as physical activity, prior joint injury, or occupational stress can impact the likelihood of OA. |
| Symptoms of Osteoarthritis |
OA symptoms usually develop gradually:
- Joint pain or aching during or after activity
- Morning stiffness or stiffness after rest
- Limited range of motion
- Swelling around joints
- Muscle weakness or joint instability (e.g., knees giving away)
OA symptoms vary depending on the joint affected. For example, OA in the hips may cause pain in the groin or buttocks, while knee OA often leads to a "grating" feeling during movement.
|
| Health Consequences of Osteoarthritis |
| OA not only affects joint health but can also contribute to other health problems: |
|
| |
| Obesity and heart disease: |
Painful joints make exercise harder, increasing the risk of obesity, heart disease, and diabetes. |
| |
| Falls: |
OA in the knees or hips, as well as side effects from medications, can increase the risk of falls and fractures. |
|
Diagnosis |
Your doctor may diagnose OA by reviewing your symptoms, medical history, and by performing a physical exam. Imaging tests, such as X-rays or MRIs, may be ordered to confirm the diagnosis.
|
| Treatment Options |
| Although there is no cure for OA, several treatments can help manage the condition: |
|
| |
| Medications: |
Pain relievers like acetaminophen, NSAIDs, or topical creams can reduce symptoms. In more severe cases, prescription medications or injections (e.g., corticosteroids) may be used. |
| |
| Non-drug therapies: |
Physical therapy, support devices (orthotics, braces, splints), acupuncture, electronic stimulators, or vitamins and supplements (i.e. Glucosamine and chondroitin) |
| Exercise: |
Regular physical activity helps strengthen muscles and improve joint function. Activities like stretching, strengthening exercises, and aerobic activities are recommended. |
| |
| Weight loss: |
Reducing excess weight can decrease stress on joints and improve symptoms. |
| Physical therapy and assistive devices: |
Therapists may provide exercises, joint braces, or shoe inserts to improve function and reduce pain. |
| |
| Surgery: |
Joint replacement surgery may be considered in severe cases, especially for hips and knees. |

Self-Care and Lifestyle Tips |
Managing OA requires a combination of medical treatments and healthy lifestyle choices:
- Maintain a healthy weight to reduce stress on joints.
- Control blood sugar to prevent cartilage damage.
- Keep joints moving with regular, gentle exercise like stretching or walking.
- Protect your joints by using proper body mechanics and avoiding overexertion.
- Relax and manage stress through activities like meditation, music, or spending time with loved ones.
- Maintain a healthy lifestyle with balanced nutrition, avoiding smoking, and getting good sleep.
By following a comprehensive care plan, you can manage OA symptoms and maintain a high quality of life.
