Osteoarthritis of the Knee

Osteoarthritis of the knee is a progressive and painful condition that occurs when the protective cartilage that cushions the bones of the joint wears down. The resulting friction and inflammation can cause joint pain, stiffness, and swelling.

It's one of the most common causes of joint pain and disability, affecting millions of Americans. It can gradually worsen over time, leading to decreased range of motion. The condition is more common in older adults but can occur in younger people due to obesity, overuse injuries, or genetics.

Symptoms

Common symptoms of osteoarthritis in the knee include:

Pain and stiffness in the knee, especially during activity
Swelling and warmth in the joint
A grating or crunching feeling when moving the joint
Difficulty bending the knee
A decrease in range of motion
Limping

Diagnosis

Your doctor can diagnose osteoarthritis by reviewing your medical history, performing a physical examination, and reviewing imaging scans and tests. An X-ray can reveal the extent of joint damage. Your doctor may also recommend a magnetic resonance imaging (MRI) or computerized tomography (CT) scan to get a more detailed view of the joint.

Treatments

Treatments for knee osteoarthritis involve managing symptoms and slowing the progression of the disease. Depending on the severity of your condition, your treatment plan may include:

Nonsteroidal anti-inflammatory medications (NSAIDs)
Physical therapy and exercises
Weight loss and diet changes
Corticosteroid injections
Surgical options, such as joint replacement

Your doctor can help you decide which treatments and therapies are best for your individual needs.
