Rheumatoid arthritis vs. osteoarthritis — different diseases, different approaches

Reviewed by a board-certified rheumatologist

Watching your parent struggle to open a jar of pasta sauce tells you more than any X-ray could. Their hands aren't paralyzed, they aren't frozen in place, but the grip that used to twist lids and button shirts without a second thought has quietly disappeared. Hand osteoarthritis strips away the small movements that hold daily life together, and because hands are personal and private, most people suffer through it alone long before anyone else notices.

The Joints Wear Down, and Everything Built on Them Follows

According to the CDC, osteoarthritis affects over 32.5 million adults in the United States, and the hands are one of the most commonly involved sites. The Arthritis Foundation reports that hand OA is especially prevalent in women over sixty, with radiographic evidence appearing in more than half of women in that age group. This is not a rare condition. It is one of the most common reasons older adults lose the ability to perform everyday tasks independently.

What happens inside the joint is straightforward. The cartilage that cushions the bone surfaces wears away over decades. Without that buffer, bone grinds against bone. The joints closest to the fingertips and the base of the thumb take the worst of it because those are the joints that do the most work. Inflammation sets in. Bony growths called osteophytes develop at the joint margins. Morning stiffness settles into the fingers and loosens only partially as the day goes on. The pain is often described as a low, constant ache punctuated by sharper flares when the hand is used for gripping, pinching, or twisting.

The cosmetic changes bother some people more than the pain. Knobby, swollen joints are visible in a way that knee or hip arthritis is not. Your parent's hands are on display every time they shake someone's hand, reach for a glass, or sit at a table. Some people withdraw from physical contact because their hands look unusual or because a handshake hurts. That self-consciousness adds a social dimension to a condition that already makes daily life harder.

Pain Is Bad, but Lost Function Is Worse

The pain matters. Chronic pain is exhausting and demoralizing, and it colors everything from sleep to mood. But the loss of function is where independence actually erodes. If opening a jar hurt but your parent could still do it, that would be one thing. When the grip strength drops to the point where the jar simply will not open, that is a different problem entirely.

The ACL (Administration for Community Living) reports that difficulty with activities of daily living is one of the primary drivers of older adults needing assistance or transitioning to supported living environments. Hand function sits at the center of nearly every daily task. Writing, cooking, bathing, dressing, using a phone, managing medication bottles. When the hands stop cooperating, the ripple effect touches everything.

This is where depression often enters the picture. Your parent was someone who could do things. Someone competent and capable and self-sufficient. Now they need help with a jar lid. Asking for help is deeply difficult for many older adults, and the identity shift from capable to dependent can be devastating. The hobbies that filled their time and connected them to other people, sewing, writing letters, playing cards, gardening, fall away one by one. The world shrinks because the things that made it full have become painful or impossible.

What Treatment Looks Like

Pain management is usually the starting point. Over-the-counter anti-inflammatory medications like ibuprofen or naproxen reduce both pain and inflammation. Acetaminophen addresses pain but does nothing for inflammation. The NIH notes that topical NSAIDs, applied directly to the skin over the affected joints, can be effective for hand OA with fewer systemic side effects than oral medications, which matters for older adults already managing multiple prescriptions.

Heat helps many people. Warm water, heating pads, warm paraffin wax baths can soothe painful joints and make movement easier before activities that require hand use. Cold works better for others, particularly when joints are acutely swollen.

Splints designed by an occupational therapist can make a tremendous difference. A thumb splint that stabilizes the CMC joint, the joint at the base of the thumb where OA hits hardest, reduces pain during gripping and pinching tasks. Nighttime splints reduce morning stiffness. These are custom-fitted to your parent's hand, and the difference between a well-designed splint and a generic one from the drugstore is significant.

Hand exercises maintain and sometimes improve function. Gentle range-of-motion work, stretching, and strengthening exercises that do not overload the joints help prevent further decline. The Arthritis Foundation recommends consistent, daily hand exercises as a core part of OA management. A physical or occupational therapist can design a program specific to your parent's limitations.

Corticosteroid injections directly into the worst-affected joints provide relief lasting weeks to months. This is particularly useful for the thumb base joint, which bears disproportionate stress during daily activities. In severe cases, surgery becomes a consideration. Joint fusion eliminates motion but eliminates pain. Arthroplasty reshapes or replaces the joint to improve both pain and function. Surgery is typically reserved for cases where conservative treatments have been exhausted and functional limitation is severe.

Adapting Daily Life Changes Everything

Adaptive tools are not admissions of defeat. They are practical solutions that let your parent keep doing the things that matter to them. Jar openers that provide mechanical advantage. Ergonomic pens with thicker, cushioned grips. Button hooks that bypass the need to pinch tiny buttons with painful fingers. Weighted utensils and built-up handles on forks and spoons. Keyboards and mice designed for arthritic hands. Specialized can openers that require less grip strength.

A jar opener that lets your parent open jars independently is not a sad thing. It is a tool that means they do not have to ask for help, and that distinction matters enormously to someone whose sense of self is tied to doing things on their own.

Routine modifications help too. Pullover shirts instead of button-downs. Pants with elastic waists or zippers instead of clasps. Voice-to-text software instead of typing. Larger pens instead of standard ones. The goal is not to do everything the way it has always been done. The goal is to keep doing the things your parent wants to do, adapted in whatever way makes that possible.

Occupational therapy is one of the most valuable referrals for hand OA. An occupational therapist observes how your parent accomplishes tasks, identifies where pain and weakness create barriers, and recommends specific tools and techniques. They teach joint protection strategies, energy conservation methods, and better movement patterns that reduce stress on damaged joints. Many adaptive tools are available through medical supply companies, online retailers, and organizations focused on aging, with costs ranging from a few dollars for a jar opener to more for custom splints or specialized equipment.

Heat before activity helps. If your parent knows a task requiring hand strength is coming, warming the hands first with warm water or a heating pad reduces pain and improves function during the activity. Avoiding overuse matters too, but that means pacing and scaling rather than giving up entirely. Doing things more slowly, taking breaks, asking for help with the heaviest tasks while handling the rest independently. These are not failures. They are adaptations to a changed reality, and they allow your parent to keep doing what matters.

Frequently Asked Questions

Is hand osteoarthritis the same as rheumatoid arthritis?
No. Osteoarthritis is caused by mechanical wear of joint cartilage over time. Rheumatoid arthritis is an autoimmune disease where the immune system attacks the joint lining. They affect different joints in different patterns, progress differently, and require different treatments. Your parent's doctor can distinguish between them through examination, blood tests, and imaging.

Will hand exercises make the arthritis worse?
Gentle, appropriate exercises prescribed by a therapist do not worsen osteoarthritis. The Arthritis Foundation recommends daily hand exercises as part of standard OA management. The key is doing the right exercises at the right intensity, not pushing through sharp pain, and working with a professional who understands the condition.

Does Medicare cover occupational therapy for hand arthritis?
Medicare Part B covers occupational therapy when it is medically necessary and ordered by a doctor. Your parent will typically pay the Part B deductible and 20% coinsurance. Coverage applies to evaluation, treatment sessions, and the design of custom splints. The therapist's office can verify coverage before starting.

Can surgery fix hand osteoarthritis?
Surgery can address specific joints that are severely damaged and causing significant pain or functional loss. Joint fusion eliminates motion but eliminates pain. Joint replacement or reconstruction can improve both. Surgery is generally considered only after conservative treatments have been tried, and outcomes vary depending on which joints are involved and the extent of damage.

Are there foods or supplements that help with osteoarthritis?
The NIH notes that glucosamine and chondroitin supplements have mixed evidence for osteoarthritis, with some studies showing modest benefit and others showing none. Anti-inflammatory diets rich in omega-3 fatty acids, fruits, and vegetables may help reduce general inflammation. No supplement replaces medical treatment, but dietary changes that reduce inflammation are reasonable to discuss with your parent's doctor.

When should we see a specialist instead of the primary care doctor?
If your parent's hand function is declining despite treatment, if they are struggling with daily activities, or if the diagnosis is unclear, a referral to a rheumatologist or a hand specialist is appropriate. An occupational therapist referral is valuable at any stage for practical guidance on maintaining function.
