Osteoarthritis is the most common type of arthritis. It happens when the cartilage that lines your joints is worn down or damaged and your bones rub together when you use that joint. A healthcare provider will help you find a combination of treatments to manage your symptoms.
Osteoarthritis is the most common type of arthritis (a condition that affects your joints). Healthcare providers sometimes refer to it as degenerative joint disease or OA. It happens when the cartilage that lines your joints is worn down over time and your bones rub against each other when you use your affected joints.
Usually, the ends of bones in your joints are capped in a layer of tough, smooth cartilage. Cartilage is like a two-in-one shock absorber and lubricant — it helps the bones in your joints move past each other smoothly and safely. If you have osteoarthritis, the cartilage in your affected joints wears away over time. Eventually, your bones rub against each other when you move your joints.
Osteoarthritis can affect any of your joints, but most commonly develops in your:
A healthcare provider might classify osteoarthritis as one of two types:
Osteoarthritis is very common. Experts estimate that more than 80% of adults older than 55 have osteoarthritis, even if some of them never experience symptoms.
Around 60% of people with osteoarthritis have symptoms they can notice or feel.

The most common symptoms of osteoarthritis include:
Experts aren’t sure what causes osteoarthritis. Primary osteoarthritis usually develops slowly as you age. As you get older, normal wear and tear on your joints might contribute to their cartilage breaking down.
Anything that directly damages your joints can also cause osteoarthritis, including:
Other forms of arthritis (specifically inflammatory arthritis) can cause osteoarthritis, including:
Anyone can develop osteoarthritis. Adults older than 55 and people who are in postmenopause are more likely to develop osteoarthritis.
People with certain health conditions are more likely to experience osteoarthritis, including:
A healthcare provider will diagnose osteoarthritis with a physical exam and imaging tests. They’ll look at your joints and ask you when you first noticed any symptoms. Tell them if any activities make your symptoms worse, or if they come and go.
You might need blood tests to rule out other conditions or issues that cause similar symptoms.
Your healthcare provider will help you find treatments that relieve your osteoarthritis symptoms. There’s no cure for arthritis, and you can’t regrow the cartilage in your affected joints. Your provider will help you find ways to manage your symptoms when you’re experiencing them.
The most common treatments for osteoarthritis include:
The best way to prevent osteoarthritis is to maintain good overall health, including:
Most people with osteoarthritis need to manage their symptoms for the rest of their lives. Your healthcare provider will help you find the right combination of treatments to reduce your symptoms.
If you have osteoarthritis, it’s important to stay as active as possible. If joint pain and other symptoms make it too hard for you to move, you may face a greater risk for other serious health conditions like heart disease, diabetes and some types of cancer.
Talk to your healthcare provider if osteoarthritis makes it hard (or impossible) to stay active. They’ll help you find new treatments to manage your symptoms.
You might need to tweak your routine to make living with osteoarthritis easier. Depending on when you’re experiencing symptoms (and how severe they are), you may need to avoid or modify your activities while you’re managing symptoms. You might work with an occupational therapist if you need help performing your daily tasks. Occupational therapists are healthcare providers who can help you manage physical challenges like arthritis. They may recommend:
Visit a healthcare provider as soon as you notice any symptoms of osteoarthritis. Even minor joint pain can be a sign that you need treatment — especially if it doesn’t get better in a few days.
You can’t repair any cartilage degeneration (breakdown) that’s already happened, but starting osteoarthritis treatment can slow down further damage inside your joints.
Talk to your provider if it feels like your symptoms are coming back more often or are more severe than they used to be. Ask your provider about other treatment options or changes you can make to your existing treatments if you feel like they’re not working as well as they usually do.
Osteoarthritis usually affects people older than 55. However, there’s no set timeline or age restriction on when you might experience it. It also doesn’t start the way some health conditions do — there’s not usually an exact starting point your healthcare provider can precisely identify.
It can take a long time for the cartilage in your affected joints to wear down enough to cause pain and stiffness. So, even if you first notice symptoms around age 55, that doesn’t mean osteoarthritis started exactly at that time.
A note from Cleveland Clinic
Osteoarthritis is a type of arthritis that happens when cartilage in your joints wears down. Without that slippery, smooth shock absorber, your joints can feel stiff, painful or like they’re grinding together when you use them.
The best thing to do for osteoarthritis is to visit a healthcare provider as soon as you notice symptoms, especially if they’re making it hard to participate in your usual activities. You’ll probably have to manage your symptoms for a long time, but your provider will help you find a combination of treatments that keeps you active and your joints safe and supported.
