Knee Arthritis Exercises: What You Should Know

If you have knee arthritis, moving around might feel like the last thing you want to do. 

But the right exercises can actually make a big difference. 

They help loosen up stiff joints, build strength, and make everyday movements feel easier.

Staying active is one of the most effective ways to manage knee arthritis and keep you moving without pain. 

This guide walks you through the best exercises for knee arthritis you can do at home and how we can help support your recovery.

 

GET RELIEF FROM YOUR KNEE ARTHRITIS

 

Why Exercise Is Good for Knee Arthritis

 

Knee arthritis doesn’t mean you have to stop moving. 

In fact, regular exercise can help you feel better. 

It can:

• Reduce pain and stiffness
• Improve flexibility and movement
• Strengthen muscles that support your knees
• Improve balance and help prevent falls
• Support healthy weight, which takes pressure off your joints

When you avoid movement, joints get stiffer and muscles weaken, which can make pain worse over time. 

The key is finding the right types of movement that feel safe and doable.

 

What Are the Best Types of Knee Arthritis Exercises?

 

To protect your joints and feel your best, focus on these four types of exercises:

• Stretching to improve flexibility
• Strengthening to support your knees
• Low-impact cardio to stay active without strain
• Balance and functional moves to help with daily activities

Let’s go through simple examples of each.

 

Gentle Stretches That Help Loosen the Knee

 

Tight muscles can pull on the knee and make pain worse. 

Try these simple stretches a few times a week:

• Hamstring Stretch: Sit at the edge of a chair or stand with one heel resting on a low surface. Gently lean forward until you feel a stretch in the back of your thigh. Hold for 20–30 seconds. Switch legs and repeat.
• Calf Stretch: Stand facing a wall. Step one foot back and press the heel down while keeping your back leg straight. Lean forward slightly. You’ll feel the stretch in your calf. Hold, then switch sides.
• Quad Stretch: Stand near a wall or chair for support. Bend one knee and hold your ankle behind you, gently pulling your heel toward your glutes. Keep your knees close together. Hold, then switch legs.

 

Strengthening Exercises to Take Pressure Off Your Knees

 

These exercises help your muscles do more of the work so your joints don’t have to.

• Straight Leg Raise: Lie on your back with one leg bent and the other straight. Tighten the thigh of your straight leg and slowly lift it a few inches off the floor. Hold for a few seconds, then lower. Do 10–15 reps per leg.
• Seated Knee Extension: Sit in a sturdy chair. Slowly straighten one leg in front of you and hold for a few seconds. Lower and switch legs. Add ankle weights later if this gets too easy.
• Glute Bridge: Lie on your back with knees bent. Squeeze your glutes and lift your hips off the floor. Hold, then lower slowly. This builds strength in your glutes and hamstrings, which support your knees.
• Wall Sit (Short Hold): Stand with your back against a wall and slowly slide down into a shallow squat. Hold for 10–15 seconds, then push back up. This strengthens your thighs and core without overloading your joints.

 

Easy Cardio That’s Gentle on the Knees

 

Staying active doesn’t mean pounding the pavement. 

Try these low-impact options:

• Stationary Bike: A great way to warm up and keep your joints moving without impact. Start with just 10 minutes and build from there.
• Water Walking or Pool Exercises: The water supports your body weight, making movement easier. Try walking laps in the shallow end or using foam weights for resistance.
• Elliptical Machine: A smooth, gliding motion makes this a great option for cardio without the pounding of running or jogging.

 

Balance and Functional Movements You Can Do Daily

 

These exercises help with coordination, walking, and everyday activities:

• Step-Ups: Use a low step or curb. Step up with one foot, then the other. Step back down. Repeat 10–15 times and switch your lead leg halfway through. 
• Sit-to-Stand: From a chair, stand up without using your hands if you can. Sit back down slowly and repeat. This helps with strength and mobility.
• Standing Leg Raises: Stand and hold onto a counter or chair. Lift one leg to the side without leaning. Lower and repeat. Switch sides. This builds hip strength to help stabilize your knee.

 

How Orthobiologics Associates Can Help You Manage Knee Arthritis

 

While exercise is a key part of arthritis care, some people need extra support to get relief and stay active. 

That’s where we come in.

At Orthobiologics Associates, we offer regenerative treatments that work with your body’s natural healing process. 

These therapies can help reduce inflammation, promote tissue repair, and make it easier for you to move without pain.

• PRP (Platelet-Rich Plasma) uses growth factors from your own blood to support healing inside the joint. It’s often used alongside physical therapy or exercise to speed up recovery and reduce pain.
• PRGF (Plasma Rich in Growth Factors) is a more refined version of PRP that focuses on reducing pain and helping cartilage stay healthy.
• BMAC (Bone Marrow Aspirate Concentrate) delivers stem cells and other healing components to the joint. It’s a good option for people with more advanced arthritis who want to avoid surgery.

Our team takes time to listen, assess your condition, and build a personalized plan that combines non-surgical treatments with the right movement strategy for your body.

FAQs: Knee Arthritis Exercises

 

What is the best exercise for an arthritic knee?
The best exercises for an arthritic knee include low-impact movements like straight leg raises, hamstring stretches, glute bridges, and water walking. These help improve strength, flexibility, and joint support without adding stress to the knee.

What not to do with knee arthritis?
Avoid high-impact activities like running, deep squats, or jumping, especially if they cause pain or swelling. You should also avoid sitting or staying still for long periods, as that can make stiffness worse.

Does knee osteoarthritis hurt all the time?
Knee osteoarthritis doesn’t usually hurt all the time, but pain can come and go depending on activity, inflammation, and joint wear. Some people feel stiffness in the morning or after sitting, while others have flare-ups with too much movement.

Should I walk with an arthritic knee?
Yes, studies show that walking is generally safe and helpful for people with knee arthritis. It helps maintain joint movement, improves circulation, and supports a healthy weight. Just make sure to wear supportive shoes and take breaks as needed.

Does GAE help with osteoarthritis?
Yes, genicular artery embolization (GAE) is a minimally invasive procedure that may help reduce pain from knee osteoarthritis by limiting blood flow to inflamed joint tissues. It can be an option for people who haven’t found relief with other treatments.

Why does my knee hurt when I bend it?
Knee pain when bending can be caused by worn cartilage, inflammation, or joint stiffness from arthritis. It might also be related to weak muscles or improper joint alignment. Stretching and strengthening exercises can help reduce this type of discomfort.
