Chronic joint pain

What is chronic joint pain?

Chronic joint pain is persistent pain in one or more joints lasting longer than three months¹. By far the most common cause is osteoarthritis (OA), a condition involving changes across the whole joint, including cartilage, the underlying bone, ligaments, joint capsule, synovial membrane and surrounding muscles². OA most commonly affects the knee, hip, hand and shoulder, and less commonly the spine, where facet joint OA can contribute to chronic back pain.

OA is one of the most common chronic conditions in Australia. It is the most common form of arthritis, and one of the leading causes of pain, disability and reduced quality of life in adults, particularly from middle age onward^2,3,4. The traditional description of OA as "wear and tear" is misleading. Modern understanding frames OA as an active condition involving low-grade inflammation, bone remodelling and changes in pain processing, not simply a worn-out joint².

Other causes of chronic joint pain include inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis), crystal arthropathies (gout, pseudogout), post-injury or post-surgical joint pain, and chronic conditions where joint pain is a prominent feature, such as fibromyalgia. Inflammatory arthritis in particular requires a different treatment pathway, usually under the care of a rheumatologist with disease-modifying medication. If you have joint pain with prolonged morning stiffness (longer than an hour), multiple swollen joints, or systemic features, see your GP: this is a different picture from OA and needs early assessment.

What current evidence says about chronic joint pain care

For osteoarthritis, international and Australian guidelines have converged on a clear set of recommendations^4,5,6,2. Education, exercise and weight management form the core of first-line care for everyone with knee or hip OA, regardless of severity^4,5. Pharmacological and surgical options sit on top of this foundation, not in place of it.

Exercise has the strongest evidence base of any treatment for OA. Land-based exercise (including strengthening, walking, tai chi and stationary cycling), aquatic exercise, and structured neuromuscular exercise programs all reduce pain, improve function, and improve quality of life across knee and hip OA, with effect sizes comparable to or better than common medications, and far safer^4,5,2,7. In Australia, the GLA:D Australia program (Good Life with osteoArthritis: Denmark, adapted for Australia and coordinated through La Trobe University) provides structured education and supervised neuromuscular exercise for people with knee and hip OA. Outcomes from the Australian implementation show meaningful reductions in pain and improvements in quality of life sustained at twelve months across more than 290 sites nationally⁸.

Education (particularly understanding that pain does not necessarily equal joint damage, and that movement is protective rather than harmful) addresses one of the most common barriers to OA self-management^9,10. Weight management, for people with knee or hip OA who are overweight, is recommended because each kilogram of body weight translates to several kilograms of force across the knee joint with each step, and modest, sustained weight loss has substantial effects on pain and function^4,5,6. The framing across guidelines is supportive and goal-based, not lecturing: weight is one factor among several, and tackling it works best alongside the exercise and education components.

Medication for OA has more nuanced evidence than many patients realise. Topical non-steroidal anti-inflammatory drugs (NSAIDs) such as topical diclofenac are recommended as a first-line analgesic option, particularly for knee and hand OA, because they provide meaningful relief with much lower systemic risk than oral NSAIDs^5,4. Oral NSAIDs are useful when topical agents are insufficient, but carry cardiovascular, gastrointestinal and kidney risks that need consideration, especially in older adults. Paracetamol's evidence base in OA is weaker than once thought, and recent guidelines have downgraded its routine use. Opioids are not recommended for chronic OA pain. They have limited effectiveness and substantial harm potential, and current Australian and international guidelines advise against routine use^4,5. Intra-articular injections (corticosteroid, hyaluronic acid, platelet-rich plasma) have a contested evidence base and are usually considered case-by-case under specialist care.

Surgery has a clear place but a more limited one than many patients expect. Total knee or hip replacement is highly effective for end-stage OA when symptoms remain significant after a genuine trial of conservative care, and outcomes in Australia are among the best in the world^4,6. By contrast, arthroscopic surgery for knee OA (without a discrete mechanical problem such as a locking meniscal tear) is not recommended by current guidelines, as multiple high-quality trials have shown no benefit over conservative care^4,5.

Imaging is overused in OA. Diagnosis of knee and hip OA is primarily clinical, based on symptoms, examination and the person's age and history. X-ray and MRI findings correlate poorly with pain and function, and many people without joint pain have OA changes on imaging^2,4,6. Imaging has a role when the diagnosis is uncertain, when symptoms change suddenly, or when surgery is being considered, but it is not needed to start evidence-based conservative care.

How Pain Coach is built for chronic joint pain

Pain Coach is a chronic pain tracking app designed to be used with your physiotherapist or GP. For chronic joint pain, the daily check-in captures pain alongside the five lifestyle factors most relevant to OA management (sleep, exercise, nutrition, stress and social connection) in under two minutes a day.

Because the strongest evidence-based treatments for OA (exercise, weight management, education) work gradually over months, tracking is particularly useful for seeing the trajectory clearly. A bad week in isolation can feel like failure. The same week, in the context of a downward trend in average pain over twelve weeks, looks different². Tracking activity and function alongside pain gives you and your physiotherapist a clear basis for judging whether the exercise dose is right (enough to drive improvement, not so much it triggers flares), and provides concrete information for conversations about whether to adjust treatment, add an intervention, or consider referral for a surgical opinion if conservative care has been genuinely tried and is no longer enough.

Pain Coach does not promise a cure. OA is a long-term condition, but the realistic goal across guidelines is meaningful improvement in pain, function and quality of life, and for many people, returning to activities they had given up on^4,5. The aim is clarity, steady progress, and better-informed decisions along the way.

The five lifestyle factors and chronic joint pain

Each of the five factors Pain Coach tracks affects chronic joint pain, with exercise carrying the strongest and most direct evidence.

• Exercise and movement. Exercise is the single most important intervention in OA, strongly recommended across all current guidelines, with evidence for reduced pain, improved function and improved quality of life^4,5,2,7. Land-based exercise (walking, strengthening, tai chi), aquatic exercise, and structured neuromuscular programs such as GLA:D Australia all have evidence⁸. The most common barrier is the belief that exercise will damage the joint, but the opposite is true. Graded, sustained exercise protects joints and reduces pain over time. The key is graded and sustained, not intense.
• Nutrition and weight management. For knee and hip OA in particular, body weight is a significant factor in joint loading, and modest, sustained weight loss meaningfully reduces pain and improves function^4,5. Regular, balanced eating supports the energy needed to exercise consistently and supports general health¹¹. Pain Coach tracks plant intake, whole-food intake and added sugar so your clinician can see the pattern. It does not prescribe a specific diet.
• Sleep. Chronic joint pain disrupts sleep: pain often worsens at night, and disrupted sleep amplifies daytime pain^12,13. Tracking sleep alongside pain often reveals how much of the daytime symptom load is downstream of poor sleep, and small improvements in sleep can have outsized effects on how the joint feels.
• Stress. Persistent stress amplifies central pain processing, and unhelpful beliefs about pain (particularly fear that movement causes damage) can amplify the experience and reduce engagement with the exercise that works^14,10. Psychological support has consistent evidence for reducing distress and disability in chronic pain¹⁵.
• Social connection. OA can be isolating, particularly when it limits activities (walking, sport, gardening, social events) that previously connected you to others. Isolation and loneliness independently worsen chronic pain outcomes^16,17. Group-based programs such as GLA:D often have a social component that adds to their effect⁸. Small, regular contact with people you trust tends to correlate with better days.
