Osteoarthritis (OA) is more than a natural part of aging. It is a complex joint condition affecting millions of people globally. In 2019, approximately 528 million people worldwide were living with osteoarthritis, with the knee being the most commonly affected joint. Despite being common, OA is often misunderstood, which leads to delayed treatment and reduced quality of life.

The good news is that with early intervention, lifestyle changes, and physiotherapy, people with OA can maintain mobility, reduce pain, and continue participating in the activities they love.

What is Osteoarthritis?

Osteoarthritis is a long-term condition that affects the whole joint. Changes can occur in the cartilage, bone and other tissues within and around the joint. These changes do not always relate closely to the amount of pain or difficulty a person experiences.

Common symptoms include:

Pain and tenderness
Joint stiffness, particularly in the morning or after inactivity
Swelling and reduced range of motion
Muscle weakness around affected joints

OA most commonly affects the knees, hips, hands, and spine, but it can occur in any joint.

Case Study: Sarah, a 60-year-old librarian, experienced persistent stiffness in her hands and knees. She was initially told it was “just aging,” but a physiotherapy assessment revealed early OA. Through targeted exercises and practical adjustments at work, she was able to continue managing her daily activities with greater confidence.

Causes and Risk Factors

OA is multifactorial—caused by a combination of biological, mechanical, and lifestyle factors:

Age: The likelihood of developing osteoarthritis increases with age, although OA is not an inevitable part of getting older
Genetics: Family history increases susceptibility
Previous joint injury: A history of significant joint injury can increase the risk of developing osteoarthritis.
Body weight: Living with overweight or obesity can increase the risk of knee and hip OA through a combination of mechanical and metabolic factors.
Gender: Women are more prone to OA, especially after menopause
Certain occupational or sporting exposures: Repeated high joint loading, particularly alongside previous injury or other risk factors, may increase OA risk.

Research shows that metabolic factors, including inflammation and insulin resistance, may contribute to OA progression, highlighting the importance of nutrition and lifestyle in managing the disease.

Recognizing the Symptoms

OA symptoms develop gradually and can vary widely:

Pain during movement or after activity
Joint stiffness, often after waking or periods of inactivity
Swelling or tenderness around the joint
Reduced mobility, making daily tasks challenging

Case Study: James, a 55-year-old runner, noticed knee pain after long runs. Early X-rays showed minimal damage, but physiotherapy assessment revealed muscle imbalances and poor running mechanics contributing to his symptoms. A progressive strengthening and load-management programme helped him gradually return to running.

How Physiotherapy Supports OA Management

Physiotherapy can support people with osteoarthritis through education, therapeutic exercise, progressive strengthening, activity guidance and strategies for managing symptoms and maintaining function.

Exercise is one of the core treatments for osteoarthritis and can be adapted according to a person's needs, abilities and goals.

Practical Tip: Physiotherapy programs are individualized. Someone with knee OA may require low-impact exercises, while another person may focus on progressively building strength and capacity for work, sport or other meaningful activities.

Practical Exercise Routines for Osteoarthritis

Exercise is safe and effective for most people with OA. Here are examples of practical routines for different joints:

1. Knee Osteoarthritis

Strengthening:

Quadriceps Sets: Sit with legs straight, tighten thigh muscles for 5 seconds, repeat 10–15 times
Straight Leg Raises: Lift one leg while keeping it straight, hold 3 seconds, repeat 10 times each leg

Flexibility:

Hamstring Stretch: Sit on floor, extend one leg, reach toward toes, hold 20–30 seconds
Calf Stretch: Stand facing a wall, press heel to floor, hold 20–30 seconds

Low-Impact Cardio:

Swimming, cycling, or walking 20–30 minutes, 3–5 times per week

2. Hip Osteoarthritis

Strengthening:

Bridges: Lie on back, knees bent, lift hips slowly, hold 3–5 seconds, repeat 10–15 times
Side-Lying Leg Raises: Strengthen hip abductors, 10–15 reps each side

Flexibility:

Hip Flexor Stretch: Kneel on one leg, push hips forward gently, hold 20–30 seconds

Balance Exercises:

Single-Leg Stands: Hold onto a chair for support, 10–15 seconds each leg

3. Hand Osteoarthritis

Strengthening:

Therapy Putty Exercises: Squeeze putty 10–15 times
Finger Lifts: Place hand flat, lift each finger slowly

Flexibility:

Finger Stretch: Stretch fingers apart gently, hold 5–10 seconds
Thumb Opposition: Touch thumb to each fingertip in turn

Functional Tips:

Use ergonomic tools for writing, cooking, and typing

If you're looking for a more structured approach, my Complete Knee Osteoarthritis Self-Management Workbook includes a progressive four-phase exercise programme alongside education, assessments, flare-up guidance and practical self-management tools.

These exercises provide general guidance and are not individually prescribed. What is appropriate can vary depending on your symptoms, health, abilities and other circumstances. Seek appropriate professional advice if you are unsure whether an exercise is suitable for you, if your symptoms are unusual or concerning, or where individual assessment is indicated.

Lifestyle and Long-term Self-Management

Long-term osteoarthritis management can involve a combination of regular physical activity, exercise, weight management where appropriate, healthy lifestyle habits and strategies for managing changing symptoms.

Preventing OA progression involves a holistic approach:

Regular low-impact exercise to strengthen muscles
Injury prevention and rehabilitation after trauma
A balanced, nutritious diet as part of overall health and, where appropriate, weight management.
Sleep and stress management to support overall health, wellbeing and symptom management.

Case Study: Linda, a 70-year-old retiree, incorporated yoga and resistance training into her routine. Over six months, she reported less knee pain, better mobility, and improved confidence in walking.

Tip: A combination of education, exercise and appropriate lifestyle strategies can support long-term osteoarthritis self-management.
