Physiotherapy for Arthritis — Can It Help and What Does It Involve?

Arthritis affects around 10 million people in the UK, making it one of the most common reasons people seek physiotherapy. The two most common types — osteoarthritis and rheumatoid arthritis — have different causes, but physiotherapy plays an important role in managing both. This guide explains what physiotherapy can do for arthritis, what the evidence says, and what to expect from treatment.

What is Arthritis?

Osteoarthritis (OA) is the most common form — a degenerative joint condition in which the cartilage (the smooth surface protecting joint ends) thins and breaks down. It most commonly affects the hips, knees, hands, and spine. OA is not simply "wear and tear" — it involves the whole joint, including the bone, muscles, and surrounding tissues. The severity of pain does not correlate well with the degree of change seen on X-ray or MRI.

Rheumatoid arthritis (RA) is an inflammatory autoimmune condition in which the immune system attacks the joint lining (synovium). It is managed primarily by rheumatologists with disease-modifying drugs, but physiotherapy plays an important role in managing the musculoskeletal consequences — joint protection, maintaining strength and flexibility, and managing flares.

Can Physiotherapy Help Arthritis?

Yes — and this is not just clinical opinion. It is backed by robust evidence and endorsed by NICE (National Institute for Health and Care Excellence). NICE guidelines for osteoarthritis explicitly recommend exercise and physiotherapy as first-line treatments — before consideration of surgery or steroid injections.

Research consistently shows that exercise reduces pain and improves function in osteoarthritis as effectively as pain medication, with fewer side effects. The benefits are most significant when the exercise is supervised and progressive — which is what physiotherapy provides.

What Does Physiotherapy for Arthritis Involve?

Assessment and Diagnosis Confirmation

Your physiotherapist will assess the affected joints, surrounding muscle strength, range of motion, gait, and functional capability. They will confirm whether your symptoms are consistent with arthritis or identify other contributing factors (such as a muscle weakness pattern that is loading the joint abnormally).

Exercise Therapy — The Core Treatment

Exercise is the most evidence-based treatment for osteoarthritis. The goals are: strengthening muscles around the joint (reducing joint load), improving range of motion and flexibility, improving balance and proprioception (reducing falls risk), and improving cardiovascular fitness and general wellbeing.

For knee osteoarthritis, key exercises include quadriceps strengthening (straight leg raises, leg press at appropriate resistance, partial squats), hip abductor strengthening, and low-impact cardiovascular exercise (cycling, swimming). For hip osteoarthritis, the focus is on hip abductor (gluteus medius) and hip extensor (gluteus maximus) strengthening, alongside hip mobility. For hand arthritis, fine motor exercises, grip strengthening, and joint protection techniques are central.

Manual Therapy

Joint mobilisation and soft tissue massage are used alongside exercise in osteoarthritis management. Manual therapy alone does not change the underlying joint but can reduce pain, improve joint mobility, and allow patients to exercise more effectively. It is used as an adjunct to exercise, not a replacement for it.

AlterG Anti-Gravity Treadmill for Arthritic Joints

At Lambert Sports Clinic we have an AlterG anti-gravity treadmill — a pressurised walking and running rehabilitation tool that reduces bodyweight load from 20–80%. For patients with moderate-to-severe osteoarthritis of the hip or knee, conventional ground-level walking may be too painful to exercise effectively. The AlterG allows walking at reduced joint load, maintaining muscle activity and cardiovascular benefit while managing pain. This is particularly valuable for heavier patients or those awaiting joint replacement surgery.

Advice and Self-Management

Education is an undervalued part of arthritis management. Your physiotherapist will advise on activity pacing (managing flares without avoiding activity), joint protection principles, appropriate footwear and orthotics, managing weight (which significantly affects joint load), and when to progress or modify exercise during flares.

Arthritis in the Knee — Key Points

• Quadriceps weakness is both a cause and consequence of knee OA — strengthening the quads is essential
• Cycling and swimming are preferred over running for knee OA — lower joint load
• Weight loss of even 5–10% significantly reduces knee pain and load
• Surgery (knee replacement) is effective but should be considered after conservative management has been optimised

Arthritis in the Hip

• Hip OA often presents with groin pain, reduced rotation, and a limp
• Gluteus medius strengthening reduces joint load significantly
• Hip replacement has excellent outcomes, but physiotherapy can delay surgery by years if started early
