Knee Pain: Causes, Arthritis & Exercises That May Help

Knee pain has several possible causes, and exercises work best when chosen for your symptoms and ability. Osteoarthritis is one possibility; pain location or a difficult stair climb alone cannot confirm the diagnosis.

For an individual assessment, see our knee pain assessment and care.

Why Knee Pain Develops (Causes)

Signs Your Knees Need This Blueprint (Symptoms)

• A dull ache after running, squatting, or climbing stairs, without a specific injury moment
• Knees that feel unstable or "give way" occasionally under load
• Visible inward collapse of the knee during squats or landing
• Stiffness or mild swelling after longer activity that settles with rest
• A history of knee pain that eases and returns depending on activity levels

The Importance of Glutes and Hips

Exercises for Hip-Driven Stability:

1. Side-Lying Leg Lifts (Hip Abduction): Focus on slow, controlled movement. Do not let your hips roll back. This directly targets the gluteus medius.
2. Clamshells (with a band): The best exercise for isolating and strengthening the small, deep hip rotators. Keep your feet together and rotate your top knee upward.
3. Glute Bridges: Excellent for overall glute max and hamstring strength, which helps unload the knee.

Strengthening the Knee Directly (Treatment Options)

Once hip stability is established, we can focus on the muscles crossing the knee joint itself. These exercises are crucial for shock absorption and controlled movement.

Exercises for Controlled Loading:

4. Wall Slides (or Mini-Squats): Stand with your back against a wall and slide down into a 45-degree squat. This builds quad endurance with minimal shear force.
5. Seated Knee Extensions (Light Resistance): Using a light ankle weight or resistance band, slowly extend the leg to strengthen the quadriceps. Focus on the final 30 degrees of extension.
6. Hamstring Curls (Standing or Prone): Use an ankle weight or resistance machine to isolate the hamstrings, which protect the ACL and prevent hyperextension.

Functional Mobility and Resilience

The final phase integrates strength into real-world movements, ensuring your knee can handle daily activities and sport.

Exercises for Resilience:

7. Single-Leg Romanian Deadlift (RDL): This demanding exercise requires balance and simultaneous strength in the hamstrings, glutes, and core, teaching them to work together to stabilize the knee.
8. Controlled Step-Ups: Use a low box or step. Focus on pressing through the heel of the front foot (glutes) and controlling the descent very slowly.

It is vital to approach knee health with consistency, not intensity. All these movements should be performed slowly and deliberately, prioritising perfect form over heavy weight. For post-surgical clients or those with severe osteoarthritis, always ensure these exercises are cleared and monitored by your physiotherapist to ensure proper load progression and safety. Build these eight pillars of strength, and your knees will reward you with decades of pain-free activity.

When to See a Physiotherapist

This blueprint is built for prevention and general knee resilience — it isn't a substitute for an assessment if you have sharp or worsening pain, a knee that locks or catches, significant swelling, or pain that started with a specific twisting or impact injury. In those cases, see a physiotherapist before starting a new strength programme so exercises are matched to what your knee can actually handle right now.

Is every painful knee osteoarthritis?

Osteoarthritis is different from inflammatory arthritis and injuries affecting other knee structures. A history and examination help distinguish them; the same exercise routine is not appropriate for every painful or swollen knee.

For osteoarthritis, therapeutic exercise can be adapted to improve strength and daily function. Progress is about tolerating activity and doing meaningful tasks more comfortably, not promising to reverse every structural joint change.

What should I tell a clinician before exercising?

Explain where pain is felt, whether the knee swells, locks or gives way, how symptoms started and which tasks are difficult. These details are clues rather than a self-diagnosis chart. Seek assessment for significant injury or concerning changes rather than forcing an online exercise routine.
