The Warning Signs of Osteoarthritis
This is the third in a series of general articles about osteoarthritis.
The Warning Signs of Osteoarthritis
STIFFNESS is a joint after getting out of bed or sitting for a long time.
SWELLING in one or more joints
A CRUNCHING FEELING or the sound of bone rubbing on bone.
About a third of people whose x-rays show evidence of osteoarthritis report pain or
other symptoms. For those who experience steady or intermittent pain, it is typically
aggravated by activity and relieved by rest. If you feel hot or your skin turns red you
probably do not have osteoarthritis. Check with your doctor about other causes, including
rheumatoid arthritis.
How Do You Know if You Have Osteoarthritis?
This is the second in a series of general articles about osteoarthritis.
Usually, osteoarthritis comes on slowly. Early in the disease, your joints may ache after
physical work or exercise. Later on, joint pain may become more persistent. You may
also experience joint stiffness, particularly when you first wake up in the morning or have
been in one position for a long time.
Although osteoarthritis can occur in any joint, most often it affects the hands, knees, hips
and spine (either at the neck or lower back). Different characteristics of the disease can
depend on the specific joints affected. For general warning signs of osteoarthritis, check
back later in the week for an article called The Warning Signs of Osteoarthritis. For
information on the joints most often affected by osteoarthritis, please see the following
descriptions.
Hands: Osteoarthritis of the hands seems to have some heredity characteristics; that is, it
runs in families. If your mother or grandmother has or had osteoarthritis in their hands,
you’re at greater-than-average risk of having it too. Women are more likely than men to
have hand involvement and, for most, it develops after menopause.
When osteoarthritis involves the hands, small bony knobs may appear on the end joints
(those closest to the nails) of the fingers. Ther are called Heberden’s nodes. Similar
knobs, called Bouchard’s nodes, can appear on the middle joints of the fingers. Fingers
can become enlarged and gnarled, and they may ache or be stiff and numb. The base of
the thumb joint is also commonly affected by osteoarthritis.
Knees: the knees are among the joints commonly affected by osteoarthritis. Symptoms
of knee osteoarthritis include stiffness, swelling, and pain, which make it hard to walk,
climb and get in and out of chairs and bathtubs. Osteoarthritis in the knees can lead to
disability.
Hips: The hips are also common sites of osteoarthritis. As with knee osteoarthritis,
symptoms of hip osteoarthritis include pain and stiffness of the joint itself. But sometimes
pain is felt in the groin, inner thigh, buttocks or even the knees. Osteoarthritis of the hip
may limit moving and bending, making daily activities such as dressing and putting on
shoes a challenge.
Osteoarthritis Basics: The Joint and Its Parts
This is the first in a series of general information articles about osteoarthritis.
Osteoarthritis Basics: The Joint and Its Parts
A joint is the point where two or more bones are connected. With a few exceptions (in the skull and pelvis, for example), joints are designed to allow movement between the bones and to absorb shock from movements like walking or repetitive motions. These moveable joints are made up of the following parts:
Cartilage: a hard slippery coating on the end of each bone. Cartilage, which breaks down and wears away in osteoarthritis, is described in more detail below.
Joint capsule: a tough membrane sac that encloses all the bones and other joint parts.
Synovium: a thin membrane inside the joint capsule that secretes synovial fluid.
Synovial fluid: a fluid that lubricates the joint and keeps the cartilage smooth and healthy.
Ligaments, tendons, and muscles are tissues that surround the bones and joints, and allow the joints to bend and move. Ligaments are tough, cord-like tissues that connect one bone to another. Tendons are tough, fibrous cords that connect muscles to bones. Muscles are bundles of specialized cells that, when stimulated by nerves, either relax or contract to produce movement.
Do I have Osteoarthritis In My Feet and Hands?
Q. I suspect I have osteoarthritis in my feet and hands. I would like to know, and better yet, I’d like to find out more about your research studies. Is a test for osteoarthritis easy? I just had a bone density test 30 days ago, but didn’t go back to get my results, but I can. Please let me know about the research studies and what to expect regarding testing for it. thanks.
A. Dear RD,
You asked seemingly simple and direct questions. I would like to be able to answer in the same manner.
Unfortunately, it is not quite as straight forward as we would all like. There is no one test to tell if you have osteoarthritis in your hands and your feet. Unlike some of the rheumatoid forms of arthritis, there are no blood tests or other tests currently available to diagnose or stage Osteoarthritis. Now, as in the past, Osteoarthritis is diagnosed clinically by a doctor asking questions and doing an exam. Some of the questions include: which joints are involved? do they hurt? when do they hurt? are they swollen? are they misshapen? have you lost strength? are there activities that you limit or avoid? did your joints change suddenly or over time? is there anything that makes them feel better? anything that makes them feel worse?
If an x-ray machine is available, a doctor might follow the physical exam with x-rays. Signs of Osteoarthritis on x-rays included joint space narrowing, , thickening of the edges of the bone, bone spurs, erosions under the edges of the bone, and bone deformities. Severe Osteoarthritis might show the ends of two bones touching. Additionally, there are now other imaging methods including CT’s and MRI’s. Both of these show about the same information as the x-rays – and then some. They provide 3-D rather than 2-D images and also show the soft tissues in addition to bone. Theoretically, MRI’s and CT’s would be able to diagnose Osteoarthritis at earlier stages than can be done in the x-rays, but to my knowledge guidelines for earlier diagnosis are not available yet.
A bone density test won’t tell you whether or not you have Osteoarthritis, it will tell whether you have osteopenia or osteoporosis. So, while it is helpful to know whether you have lost bone density, that particular test won’t tell you anything about whether you have Osteoarthritis in your hands or feet.
Part of the problem with diagnosing Osteoarthritis is that it appears to have some aspects that may be the same for every possible Osteoarthritis site in the body and there are some differences based on the specific joint(s) involved. This has complicated both the diagnosis and treatment of Osteoarthritis. That is one of the reasons that The Arthritis Research Institute of America is studying this very common disease which causes many people so much difficulty – we still just don’t know that much about it. The Clearwater Osteoarthritis Study (COS) has collected information for 20 years on hands, feet, knees, and necks as well as lifestyle information. As more data becomes available for analysis, we will be sharing the results of our findings in published papers, on our website and in our blogs.
Please see the recent and upcoming blogs for more specifics on what we are working on now.

Who knew a self administered survey with just over 130 questions, a physical exam and a few x-rays could be such a gold mine?! As ARIA’s biostatistician, I have the privilege of working with top epidemiologists to unravel some of the mysteries of osteoarthritis. There is still is so much to be learned about its etiology, diagnosis, and prognosis. Osteoarthritis can be defined in several ways: clinically, radiographically, and/or symptomatically. Interestingly, the experts cannot arrive at a conclusion of which definition to use; there are so many factors to consider. The old paradigm that osteoarthritis is the “wear and tear” form of arthritis is making room for one that considers it a systemic disease, much like cardiovascular or coronary disease, even diabetes.
One of ARIA’s goals, as I see it, is to add to what is known about osteoarthritis and untangle the many pathways to this disease. Present and future epidemiological, clinical and genetic research may eventually provide a consensual definition for osteoarthritis. One of the challenges researchers face when sorting through previous research is trying to draw conclusions about a topic when there are multiple definitions for an outcome. Multiple definitions make comparing results difficult and obstruct definitive conclusions. Any information ARIA can add to osteoarthritis research brings the research community one step closer to correctly defining this disease. Personally, I am awed that my statistical skill provides information on the distal and proximal risk factors of osteoarthritis. Needless to say, I take
my job of analyzing this data very seriously as it could reveal modifiable and unmodifiable risk factors
that may one day eliminate or greatly reduce my own disability from arthritis.
When not investigating associations of factors with osteoarthritis, I enjoy exploring Florida’s waterways and beaches. These excursions are a family affair. I am accompanied by my husband and three small children (aged 3.5yrs, 1.88yrs, and 0.33yrs). Born and raised in the City of Chicago, I am a Romanian American and first generation college graduate. I vaguely remember the ’85 Bears and the citywide celebration… wasn’t much of a football fan at the time. I am grateful to be living in Tampa Bay… I am a warm weather lady! Two interesting coincidences: my neighbor’s house was transported down the road from ARIA’s previous directors’ grandfather’s property and Dr. Barrett, founder, has traveled to
Romania numerously. My feeling is that I am meant to be a part of ARIA.
