Knee Pain Management: Exercises, Treatment Options, and Ways to Protect Your Knees

Knee pain management starts with understanding why your knee hurts and choosing strategies that match the underlying problem. Knee pain can result from an injury, overuse, arthritis, muscle weakness, poor movement patterns, or other conditions. While mild symptoms may improve with activity modification and home care, persistent, severe, or unexplained pain deserves professional evaluation.

The good news is that knee pain does not always mean you need to stop moving. Current clinical guidance increasingly emphasizes appropriately tailored exercise, education, and weight management when appropriate, particularly for knee osteoarthritis.

What Causes Knee Pain?

Knee pain has many possible causes, so treatment should not be based on pain alone.

Common causes include:

• Osteoarthritis: Gradual cartilage and joint changes can cause pain, stiffness and reduced mobility.
• Sprains and strains: Stretching or tearing of ligaments and muscles can occur after twisting or sudden movements.
• Meniscus injuries: A damaged meniscus may cause pain, swelling, catching or locking.
• Tendinitis: Repetitive running, jumping or other activities can irritate tendons.
• Patellofemoral pain: Pain around or behind the kneecap may be associated with activity, muscle weakness or movement mechanics.
• Bursitis: Inflammation of a fluid-filled sac around the knee can cause localized pain and swelling.
• Gout or infection: A hot, red and suddenly painful knee requires prompt medical assessment.

Knee pain may develop suddenly after an injury or gradually through repetitive stress. Johns Hopkins identifies aging, injury and repeated stress as common contributors.

Important: Do not assume that every painful knee has arthritis. The location, timing, swelling, movement limitations and history of injury can help a healthcare professional determine the likely cause.

How to Manage Knee Pain

Effective knee pain management is usually a combination of symptom control, appropriate movement and treatment of the underlying cause.

For a mild flare or minor injury, temporarily reducing aggravating activities may help. Ice can be useful for pain and swelling, while compression and elevation may also help after some injuries. The NHS recommends using an ice pack wrapped in a towel for up to 20 minutes at a time rather than applying ice directly to the skin.

For longer-term knee problems, avoiding movement altogether is usually not the goal.

Evidence snapshot for knee osteoarthritis management

Management approach	Current evidence/guidance	Typical role
Therapeutic exercise	Strongly supported	Foundation of management
Weight management when appropriate	Strongly supported	Can reduce symptoms and improve function
Topical NSAID	Recommended in current guidance	Short-term symptom relief
Physical therapy	Commonly recommended	Individualized strength/mobility program
Oral NSAIDs	May help but require safety considerations	Short-term medication option
Corticosteroid injection	Can provide short-term relief	Selected patients
Surgery	Reserved for appropriate cases	Severe structural disease or failed conservative care

The 2026 ACE framework identifies patient education, exercise programs and weight management as mainstay strategies for knee osteoarthritis. NICE similarly recommends therapeutic exercise and weight management as core treatments and recommends topical NSAIDs for knee osteoarthritis.

Medication should be discussed with a healthcare professional or pharmacist, particularly if you have other medical conditions or take other medicines.

Best Exercises for Knee Pain

The best exercise depends on why your knee hurts, but strengthening and mobility work are commonly important components of rehabilitation.

Good starting options may include:

1. Straight-leg raises
2. Side-leg raises
3. Supported squats
4. Glute bridges
5. Hamstring stretches
6. Quadriceps stretches
7. Gentle knee-bending exercises

HSS physical therapists emphasize strengthening the muscles around the knee and improving flexibility and mobility.

Start with a comfortable range of movement. Mild muscular effort can be expected, but sharp or progressively worsening joint pain is a reason to stop and reassess.

Strengthening Exercises for the Knees

Strong quadriceps, hamstrings, glutes and hip muscles can help support the knee during everyday activities.

Beginner-friendly exercises include:

• Straight-leg raises: Strengthen the quadriceps without repeatedly bending the knee.
• Glute bridges: Train the glutes and posterior chain.
• Side-leg raises: Strengthen the hip muscles that contribute to lower-limb stability.
• Chair squats: Build functional leg strength while allowing you to control the depth.
• Step-ups: Can be introduced gradually when basic exercises are comfortable.

HSS recommends progressive strengthening and notes that the muscles of the legs and glutes help stabilize the knee during movement. Its current exercise guidance suggests performing strengthening exercises around two to three times per week, prioritizing form and gradually increasing resistance.

For persistent pain, a physical therapist can personalize the exercise selection, repetitions and progression.

Stretching and Mobility for Knee Pain

Stiff hips, hamstrings, quadriceps or calves can affect how you move and may contribute to discomfort around the knee.

Useful mobility exercises can include:

• Hamstring stretches
• Quadriceps stretches
• Calf stretches
• Gentle knee bends
• Hip mobility exercises

Stretch slowly and avoid forcing the joint into a painful position. HSS recommends combining stretching with strengthening because both flexibility and muscle capacity can influence how the knee handles activity.

If you spend long periods sitting, regular movement breaks may also help reduce stiffness.

Low-Impact Exercises for Knee Health

You do not have to run or jump to improve cardiovascular fitness.

Low-impact options include:

• Walking
• Stationary cycling
• Swimming
• Water aerobics
• Elliptical training
• Gentle yoga

HSS specifically highlights walking, biking, water exercise and yoga as potentially useful choices for people with sore knees when the activities can be performed comfortably.

Choosing an activity

Activity	Joint impact	Best for
Swimming	Very low	Cardio with reduced weight-bearing
Water aerobics	Very low	Beginners and painful joints
Cycling	Low	Cardio and controlled knee movement
Walking	Low	Everyday fitness
Elliptical	Low	Higher-intensity cardio
Running	Higher	Only when tolerated and appropriate

If walking for 30 minutes causes discomfort, shorter sessions may be easier to tolerate. You can gradually increase duration as your symptoms allow.

How to Protect Your Knees During Exercise

Good knee protection is less about avoiding exercise and more about managing load intelligently.

Warm up first. Spend several minutes doing gentle movement before more demanding activity.

Increase gradually. Avoid suddenly doubling your walking distance, running volume or resistance training.

Use proper technique. Keep movements controlled and choose a range of motion you can manage comfortably.

Wear appropriate footwear. Comfortable, activity-appropriate shoes can make exercise easier to tolerate.

Modify painful activities. If jumping or running aggravates your knee, temporarily switch to cycling, swimming or another lower-impact activity.

Don’t push through worsening pain. HSS advises finding an activity that allows you to remain active without progressively increasing symptoms.

For people with knee osteoarthritis, braces, walking aids or other supports may be appropriate in selected circumstances, but they should not automatically replace exercise. NICE advises against routinely using braces, supports or insoles unless specific instability or biomechanical issues justify them.

When Should You See a Healthcare Professional for Knee Pain?

Seek medical advice if knee pain:

• Does not improve after a reasonable period of home care.
• Continues to interfere with walking or everyday activities.
• Keeps returning.
• Causes significant swelling.
• Causes the knee to lock or give way.
• Started after a significant injury.
• Makes it difficult to bear weight.

Seek urgent medical attention if the knee is severely painful, badly swollen or deformed, you cannot move it or put weight on it, or the knee becomes hot and red with fever or chills. These symptoms can indicate a serious injury or infection.

The Bottom Line

Successful knee pain management is about finding the right balance between protecting the joint and keeping it moving. For many people, appropriately selected strengthening, stretching and low-impact exercise can improve function and help control symptoms. However, the right approach depends on the cause of the pain.

Start gradually, monitor your symptoms and avoid treating persistent or severe knee pain as something you simply have to live with. When symptoms are significant, recurrent or associated with swelling, instability, locking, fever or an injury, professional evaluation is the safest next step.
