Osteoarthritis & Rheumatoid Arthritis

Arthritis is a broad term covering conditions that affect the joints, but osteoarthritis and rheumatoid arthritis are quite different in cause, presentation and management, even though both can cause pain, stiffness and reduced mobility. Understanding which one you’re dealing with matters, because while physiotherapy plays a valuable role in managing both, the approach and the broader medical context around it differ considerably.

Osteoarthritis is often described as a “wear and tear” condition, where the cartilage that cushions the ends of bones within a joint gradually breaks down over time, most commonly affecting the knees, hips, hands and spine as people age. Rheumatoid arthritis, by contrast, is an autoimmune condition, where the immune system mistakenly attacks the lining of the joints, causing ongoing inflammation. It can develop at any age, including in younger adults, and needs ongoing management with a rheumatologist alongside any physiotherapy input.

What causes osteoarthritis and rheumatoid arthritis

Osteoarthritis develops from a combination of factors including age, previous joint injury, repetitive loading through physically demanding work or sport, joint alignment, and reduced muscle strength around the affected joint, all of which increase the load the cartilage has to absorb over time. It’s a gradual, progressive process, though how much it affects day-to-day pain and function varies significantly between people and can be influenced considerably by activity levels and muscle strength.

Rheumatoid arthritis has a different underlying cause — it’s driven by the immune system rather than mechanical wear, and its onset and flare-ups aren’t within a person’s direct control in the way osteoarthritis risk factors are. Genetics, smoking and other factors are thought to contribute to why the immune system begins attacking joint tissue, though the condition requires diagnosis and ongoing monitoring by a rheumatologist rather than physiotherapy alone.

Symptoms

Osteoarthritis typically causes joint pain and stiffness that worsens with activity and eases with rest, morning stiffness that settles within around thirty minutes, and a gradual reduction in range of motion over time, sometimes with a grinding or crunching sensation in the joint. Rheumatoid arthritis more often causes symmetrical joint pain and swelling affecting both sides of the body at once, prolonged morning stiffness lasting an hour or more, and can involve fatigue, warmth around the joints, and flare-ups where symptoms worsen for a period before settling again.

When to see a physiotherapist

Physiotherapy is well suited to helping manage pain and maintain function in both conditions once a diagnosis has been established. If you haven’t yet been diagnosed, particularly if you’re noticing symmetrical joint swelling, prolonged morning stiffness, or significant fatigue alongside joint pain, tell us — Andrew will refer you for assessment and a rheumatologist opinion where it’s needed, alongside starting physiotherapy, since rheumatoid arthritis benefits from early medical management to limit long-term joint damage. For osteoarthritis, see Andrew if joint pain is limiting your activity or worsening, as earlier input on strengthening and load management tends to help more than waiting until symptoms become severe.

Physiotherapy treatment for arthritis

While the underlying conditions differ, physiotherapy plays a valuable, complementary role in managing both:

• Manual therapy and soft tissue work to ease pain and stiffness and maintain mobility in affected joints
• Exercise rehabilitation — a tailored, low-impact strengthening programme suited to your specific joints and activity level, since building strength around an affected joint helps support and offload it during daily activity
• Activity and load management advice, helping balance staying active — which is important for joint health — with managing flare-ups or particularly painful periods
• Joint protection strategies for daily tasks and work activities that place repetitive strain on affected joints

For rheumatoid arthritis specifically, treatment is coordinated around your broader medical management with your rheumatologist and GP, rather than replacing it — physiotherapy addresses the mobility, strength and function side of things alongside the medical management of the underlying inflammatory process.

What to expect from treatment

Exercise, when it’s the right type and dose, is one of the most effective tools for managing both osteoarthritis and rheumatoid arthritis — it helps maintain joint mobility and builds the strength that supports and protects affected joints, rather than making things worse, which is a common misconception. Andrew tailors the programme to your specific joints, current activity level and, for rheumatoid arthritis, where you’re at with any current flare-up, progressing it gradually as your tolerance improves.

Managing arthritis long term

Both conditions are generally long-term rather than something that resolves completely, so the goal of physiotherapy is as much about maintaining function and managing symptoms over time as it is about a single course of treatment. Staying active with an appropriately tailored exercise programme, alongside periodic reassessment as your joints or symptoms change, is one of the most effective ways to preserve mobility and limit the day-to-day impact of either condition.
