Physiotherapy vs Injections for Arthritis: Which Is Better?
When arthritis pain becomes difficult to manage, corticosteroid injections are often considered as a treatment option. These injections deliver anti-inflammatory medication directly into the joint, providing rapid pain relief. But how do they compare to physiotherapy, and when should each be used?
Corticosteroid injections can be very effective for short-term pain relief in arthritis, particularly during acute flare-ups. They work by reducing inflammation within the joint, and many patients experience significant pain reduction within days of the injection. The benefits typically last several weeks to a few months.
However, injections have important limitations. They do not address the underlying causes of arthritis — joint damage, muscle weakness, and biomechanical problems. They are a symptom management tool, not a disease-modifying treatment. Repeated injections carry risks, including joint cartilage damage, infection, and tendon weakening. Most specialists recommend limiting injections to three or four per joint per year.
Physiotherapy, by contrast, addresses the underlying factors that contribute to arthritis pain. Strengthening exercises improve joint support and shock absorption. Flexibility exercises reduce stiffness. Manual therapy improves joint mobility. Education on joint protection and activity modification reduces daily joint stress. And aerobic exercise improves overall fitness and reduces inflammation.
Research comparing the two approaches yields interesting findings. Studies have found that exercise therapy provides comparable pain relief to injections, but with longer-lasting benefits and without the risks. A combination approach — injection for short-term relief during a flare, combined with ongoing physiotherapy — may offer the best of both worlds for some patients.
The recommended approach, according to NICE guidelines, is: start with exercise and physiotherapy as first-line treatment. Consider injections if conservative management has not provided sufficient relief, or during acute flare-ups that limit your ability to exercise. Always combine injections with physiotherapy — use the pain relief window to establish an exercise programme that provides longer-term benefit.
